After many months of speculation – and more than a little anticipation – at an event in Austin, Texas this evening, NVIDIA announced the next generation of GeForce video cards, the GeForce 1000 series. Powered by the company’s new Pascal architecture and built on TSMC’s 16nm FinFET process, NVIDIA is promising that the 1000 series will set a new high bar for performance and efficiency while also offering a collection of new features to further set it apart from its predecessors.
The first two cards out of the gate will be NVIDIA’s high-end cards, the GTX 1080 and GTX 1070 series. 1080p jokes aside, these are straightforward successors to what has now been NVIDIA’s product stack naming scheme since 2010, with the GTX 1080 representing their new high-end card while the GTX 1070 is a cheaper card meant to hit the enthusiast sweet spot. These cards will be launching over the next month, with GTX 1080 hitting the market May 27^th, and GTX 1070 two weeks later, on June 10^th. They will be priced at $599 and $379 respectively.

Our Skylake NUC review had a brief section on the storage subsystem performance. The comments section raised a few questions about the inability of SSDs such as the Samsung SSD 950 PRO to achieve maximum performance in the NUC. After some discussion with Intel, we discovered some interesting aspects in the design of Skylake-U systems that have a bearing on the performance of some M.2 PCIe SSDs. These can affect the consumer's choice of SSDs for a Skylake-U system - be it a NUC or an user-upgradeable notebook. In this article, we quantitatively explore various M.2 SSD options for the Skylake NUC. This will help readers in choosing the right SSD that fits their use-case requirements and budgets.

After posting several teasers on the official twitter feed, Xiaomi has now announced a large battery, large screen ‘smartphone’ that blurs the line between 7-inch tablets and 6-inch smartphone. The Mi Max is a step above the previous Mi Note devices, trying to combine the pervasive ‘thin’ design in modern smartphones while also adding plenty of battery life. The only way to effectively do this is to add area, so the final result is a 6.4-inch device.

The phablet will be offered in three models, similar to the Mi 5. The low-end model, coming it at an equivalent of $230, will feature a base Snapdragon 650 with 3GB of DRAM and 32GB of storage. Moving up the chain changes the SoC to the 652 and doubles the storage. The best version tops out at 4GB of DRAM and 128GB of storage, and all three allow installation of a 128GB microSD card in place of one of the SIM cards.

The Snapdragon 650 and 652 are renamed models of the 618 and 620 respectively, as we reported in December. The two SoCs differ in the number of A72 cores – the 650 is a ‘six-core’ part, featuring dual ARM Cortex A72 cores at 1.8 GHz and quad ARM Cortex A53 cores at 1.44 GHz in a big.LITTLE configuration, whereas the 652 has quad-A72 cores at the same frequency. These parts have an 3 or 4GB of DRAM (in an LPDDR3 memory interface we assume), along with Adreno 510 graphics. In the Mi Max, this powers the 6.44-inch display running at a Full HD (1920x1080) resolution, which comes to a 74.8% screen-to-body ratio.
The SoCs use Qualcomm’s integrated X8 LTE modem, rated at category 7, and supports dual 20 MHz carrier aggregation. The Mi Max will support dual 4G SIM cards (one slot also supports microSD), a rear based fingerprint sensor, a 16MP PDAF rear camera and a 5MP front camera with an 85º wide-angle lens. The device weighs in at 203g, which as a whole is not too dissimilar from the 6-inch HTC One Max.

Other features include Quick Charge 3.0 (rated at 83% in 30 minutes), active noise cancellation and 802.11ac, but USB is only at 2.0 speeds. Black, White and Gold colors are to be released, although release dates outside of China are unknown at this point.
Xiaomi Announces MIUI 8.0

With Xiaomi devices, the default OS uses their custom Mi User Interface (MIUI), and as part of the announcement today version 8.0 is soon to be available to Chinese users who sign up to the beta program. Mi 2/2S/3/4/4C/4S/5/Max and Redmi/Mi Note devices are supported, with beta testing starting on June 1^st. MIUI 8.0 will include a new power saving mode that freezes background activity, multi-window management, fingerprint security for notes, a bundled QR and barcode scanner, a mathematics solver included, an updated camera and gallery software, and a base Chinese font redesign.

Last time I wrote about smartphones beyond the odd news post and live blogs at events, I had purchased a $160 smartphone for my own use that ran four days on a single battery charge. Not too long after, Huawei invited me over to their UK office to show me the Mate S, and their new Force Touch edition. Andrei’s review of the Mate S had been uploaded only the previous day, so part of the discussion was around some of the findings in that review, but the purpose of bringing me into the London office was to actually try the new features. I was taken through the motions of Force Touch on Huawei’s hardware. I wasn’t expecting it at the time, but at the end of the demonstration they handed me the unit and said ‘try it for a while, tell us what you think’.
So I’ll admit from the start – it isn’t every day that I use a $650 smartphone. This is Huawei’s top model of the Mate S, featuring 128 GB of storage, Force Touch, and in rose gold, which sets it apart from other Mate S implementations. On the color, which is typically not one I would have considered, I had more positive than negative comments on the rose gold in the past couple of months, with most questions about the color being directed to the comparison to Apple’s equivalent. A number of people also suggested that the Mate S was copying the iPhone, which was not an uncommon sentiment.
In these ‘a month with’ pieces, I use the smartphone as a daily driver, trying to see how easy the device fits into my slightly uncommon use case. I also try to use the new features on offer when they become relevant to what I do. If you want the full review of the Mate S, please read Andrei’s very detailed breakdown of the Mate S and the Kirin 935 SoC – this piece is my expression my personal opinion as a technical user but not a smartphone reviewer.

Gallery: Two Months With: The Huawei Mate S in Rose Gold, with Force Touch

For readers who haven’t come across these posts before on AnandTech, my use case and feel about the smartphone industry is a little different from most. I’m rather tight-fisted when it comes to smartphones, and I feel anything over $200 seems a bit excessive especially when it’s my money. I use my smartphone 99% of the time as a data device, rarely making calls, but either taking pictures and talking to the family outside of work, playing basic smartphone games in downtime, or using it as a data point while working. I also write reviews on my smartphone, using Evernote during trips on the London Underground where I’d rather write for 20 minutes when I have no internet than sit idle.
This review is going to be a list of pros and cons that I’ve come across in the last couple of months that are purely related to me. Your mileage may vary. When I gave Huawei this feedback, they agreed with most of what I had to say. I also took a small video explaining some of the interesting features that were difficult to explain in text:
Pro: Fingerprint Sensor Speed

When I road-tested the HTC One max, I struggled using the fingerprint sensor they had on it. It was an early generation swipe sensor on the rear of the phone, and no matter what I did it would only unlock 30% of the time or even less. With the swipe sensor, it only worked within a small range of angles, and invariably with a large phone you do not always hold it at the same angle to unlock. Having never used any other fingerprint sensor other than that at the time, the sensor on the Mate S was superb. I logged five different fingers in the system (first two on each hand and a third finger on my right), and it beats my previous experience in two ways. Firstly, it’s a touch sensor, which means no swiping. Secondly, the response time is super quick, so if it fails to unlock another attempt is less than a third of a second away. It’s not only quick by comparison to the One max, but I’ve also played with the 6P a little bit and the Mate S easily beats the 6P in time to calculate the unlock and then retry. Because I’ve gotten so used to the Mate S, I end up removing my finger from the sensor too early on the 6P, and it asks to try again. It’s going to be a tough habit to break out of.
Con: EMUI, Software Glitches and Response to Voice

Here’s a triple whammy of annoyance. EMUI, for all its best wishes, attempts to be very iOS like. Despite being on an Android base, there is no true list of apps or app drawer, limiting each app icon to only one screen. My typical Android experience up to this point involves some app on multiple screens, just to save time, but that isn’t possible here. The background seems only to be changeable to a set of Huawei defaults, as even after two months I haven’t found a way to put my own picture there (all the normal Android ways don’t work). EMUI also interferes with a number of apps I like to use, such as a network speed monitor so I can tell when I’m on a limited connection if some app in the background is hogging all the data. My app of choice, while it starts up, seems to be ejected from memory automatically very quickly when the screen is turned off.
The voice glitching is another aspect to be wary, and this comes in two forms. Firstly, at the end of my last smartphone test, my use of an Android phone had evolved to the point where I was starting to use Google Now to do simple tasks like set reminders and alarms, or ask basic questions very easily. On the Cubot H1, a smartphone with four A53 ARM cores running at 1.0 GHz, Google Now responded immediately without hesitation. However, the Mate S has issues. Sometimes saying ‘Google Now’ doesn’t activate the feature, and when it does, the system ends up trying to load something for three seconds and you get the ‘I didn’t hear that’ because the processor was busy. That means every time you ask it something, it’s an additional delay that I could have spent typing the question into Google for.
The other voice glitch is completely random and happens about twice a month. I will have the phone on the desk or in my pocket when talking to friends when out of the blue it will start talking about how it can’t understand a command, reach a contact, or let you know where it is. It has even done this while sitting on my bed side table while speaking with my wife. There is an always on voice feature to help you find where the phone is (which never seems to activate when you are actually looking for the phone), but the fact it activates randomly and usually when it is at high volume makes the user look like a random idiot. It’s not a good look.
Pro: Knuckles

One of Huawei’s interesting features on the Mate S is the ability to do certain things with your knuckles. It sounds odd, but essentially this means striking the screen with one or two knuckles and drawing out a box or a letter to perform certain functions. Writing a C for example, no matter where you are in Android (or even when locked), will force the camera application to load. This makes it easy to take pictures rather than searching for the camera icon (which you can’t put on multiple screens due to EMUI). The software recognizes C, M and two other letters, all of which can be customized to run the application you want. Please watch the video above for a demonstration.
The other knuckle-based features aren’t that useful so much, but are still there for the odd time you show them off to friends. A double tap will take a screenshot, while forming a box on any screen will cause what is in the box to be cropped into an image, which can then have filters or shapes applied. A double knuckle double tap will let the smartphone record both audio and on-screen activity, so if you want to show how to do something to someone else, you can make a direct video recording and send it to them.
Con: Gmail App on EMUI, Split Windows

I’ll round the EMUI issues off with these two. I use the Gmail app like a number of Android users, however the EMUI implementation is extremely annoying, especially with the backgrounds in play. When you have email and a number of new messages, then scroll down the notifications bar, EMUI displays the name of the sender and the email topic in black. This is black on a gray notifications bar which is semi-transparent, but most of the Huawei backgrounds for EMUI are quite dark, meaning you can’t read anything. This just adds another couple of seconds to looking at email and completely negates a quick notification look at the subject to see if it’s something you should respond to.

Huawei does implement a variant of multitasking in EMUI called Split Windows, and is extremely similar to other multitasking arrangements in other Android and iOS devices. It’s a good feature that I can see myself using a lot of, so why list it as a con? Well I’m not sure whether it is new, or it was a last decision thing, but the split windows require each app to be able to dynamically handle the adjustment of two screens side by side – the split windows feature can’t manage it on the fly. As a result, there are only eight apps that use the feature, and they are all from Huawei, and I don’t tend to use any of them. My best use for this, because of the limited application limitation, is typically when I want to listen to music on YouTube while searching in another browser window. But both browser windows have to be using Huawei’s browser, and not the one I normally use with all my bookmarks and cookies.

Windows splt between browser and notepad

Meh: Force Touch

So Huawei technically came out with a Force/3D Touch implementation before Apple, however this implementation seems limited in scope. The two best things you can do with it is zoom in on pictures in the gallery using one finger (it comes up like a magnifying glass with a zoomed view) and weigh round fruit between 100 and 400 g (0.15-0.90 lbs). There are other non-obvious uses for Force Touch, but these are the only two I’ve used since having the device, and even then I don’t use the latter except to show the feature off. The picture zooming thing gets a bit more use, but even then it’s fairly minimal. In order to make Force Touch more of a thing, it has to be obvious that it does more in more apps.

Pro: Screen Size

Ever since I used the HTC One Max as a daily driver, I am sold in large phones. I get why they exist, and I somehow adapted to them rather quickly. The Mate S is 5.7-inches, below the 6-inch of the One max but above the 5.5-inch of the Cubot H1. The screen has a reasonable brightness range, although doesn’t go as low as some other devices like the Nexus 6P. What I would say though is you won’t be using the Mate S in high brightness mode that often. This brings me to an issue I’ve had with the Mate S: battery life.
Con: Battery Life

We covered this in the original Mate S review, but due to an issue in the SoC silicon, the memory controller consumes a lot of power when at high frequency, even when idle. For most smartphone users that means nothing, but it relies on the OS to de-clock the memory when speed is not required. I’m not sure how often this happens, but I can easily burn through 50-60% of the battery in three hours, watching video/flipping between Skype and Twitter even at low brightness while at an airport. True story.

Putting it in Flight Mode and not using it during the 10-hour flight by comparison and the device was barely sipping at the power. But it does mean the Mate S is certainly a device that requires a daily charge, sometimes before the end of the day. This was a very quick slam to the face coming from a four-day charge smartphone in my last road test.
Pro: Software Eviction on Battery

Because I’m not so liberal with spending money on smartphones, I’ve often ended up with low power, low memory devices, or I worry about what background services are eating power. I get the typical case of memory and battery anxiety, wondering if I’m still going at full speed when I need it or if the device is going to last the full day. This is especially true when using the device at an event. Luckily there are two things on the Mate S that help here: an optimization widget and a software power detector. The first one is software which I’m not sure is part of Android, but does an optimization of currently running apps. (I know that removing apps from memory means it costs power when you need them next, but somehow memory anxiety still exists, despite having 2GB to play with.) The second is the eviction on battery use – if the OS detects that a certain piece of software is causing the SoC to draw more current, it will tell you and offer to close the software. I have seen people complain that on the Mate S this feature is fairly aggressive, and it does come across that way, but at least it gives me the option to do so.
Con: Camera

As mentioned in Andrei’s review, the camera on the Mate S isn’t one of the plus points in the device. It certainly takes a picture, but I’m an unsteady photographer who wants the photo taken as quickly as possible, and sometimes that doesn’t happen. Don’t get me wrong, I’ve used the Mate S to take pictures for AnandTech Live Blogs, but when an image gets compressed to the size of ravioli it doesn’t matter too much anyway. But on the important stuff, the family photos, there are smartphones with better quality implementations at this price point. As with my other road tests, here are some example pictures.

Gallery: Example Photographs taken with the Mate S

Pro: Camera and Document Adjustment

The camera has one nice feature worth mentioning, especially for anyone having to take notes on lectures/meetings or someone who photographs a lot of documents. The Document Readjustment option in the camera attempts to detect the edges of a piece of paper, a monitor or a projection, and will tilt, stretch, rotate, expand and adjust the image as necessary to give a flat representation. This means that you can take the image at a wide angle (I’m not sure the limit, but it certainly works up to 45 degrees) and it will come out, around 80% of the time, like the photograph was taken head on. I have used this on a number of presentations over the last couple of months, and in the review of a server motherboard recently I used it when the BIOS did not have a print screen option. In this case, I’d normally set up my DSLR on a tripod and take pictures that way, but with the Mate S I was able to simply raise the camera each time on a different screen, wait a second, and then take the image. So rather than having to crop then color balance, all I had to do for 95% of the photographs is a bulk color balance. I would note however that it does seem to strip the EXIF data from the image.
Con: Call Quality

I don't have any tools that will directly measure call quality, but I found the Mate S to be difficult to use in any environment with mild background noise. When in a quiet environment though, a call was clear to hear and easy to speak to. I'm not sure if it was the position of the microphone on the bottom, but more often than not I would have to fish out my headphones and plug them in, so I could arrange the phone and speak directly into the bottom of it.

Con: Too Many Cons

I’ve been using the Huawei Mate S 128 GB with Force Touch in rose gold for over two months now. It has many good features, and some of them feel top notch in my limited testing sphere, such as the fingerprint sensor and the ability to knuckle into the camera at any time. But it has too many issues to make me fully content with the device. Most are derived from software, most likely the nature of the latest version of EMUI supported on the Mate S, but things like not being able to read email notifications at a glance or the random nature of how it likes to talk to you in the most random situations mean that I’d probably end up buying something without EMUI or flashing the device (assuming I could get all the feature I like some other way). I feel if that it was running a base version of Android, it might have given a better user experience. All that being said, the one waking day battery life (or under one day of battery on active days) is something not easy to overcome, and means carrying around a battery pack. At least anecdotally it felt like it charged rather quickly.
Along with the Mate S, part of the way through I decided to also try out the Huawei TalkBand B2 smartwatch for some time. The TalkBand B2 was a one of the cheap press event freebies, but it tracks a few smartwatch type features in a non-Android way at a low price and comes with a monochrome display. For someone who has resisted the smartwatch market up until this point, as well as being apprehensive about the utility of such devices, I decided to bite the bullet and at least have a go. I’ll write up my experiences is a separate piece and upload it shortly.

Microsoft has certainly gone all-in on their Universal Windows Platform (UWP) and have been updating it, including the name, for several years now. What originally started as WinRT apps has morphed into a much more powerful platform which can support a wide variety of apps. There’s no doubt that traditional Win32 apps made for the desktop are not going away, but with Project Centennial, Microsoft hopes to bring at least actively developed Win32 apps over to the UWP platform.
One of the main areas that Microsoft has focused on in their marketing is UWP’s support for DirectX 12 in Windows 10, and to that end they have promoted several big budget games which have come to the Windows Store as a UWP app. But the move from tablet style games to high demand PC games was not entirely smooth. The UWP platform operates in a different way than traditional Win32 games, and it lacked several features that PC gamers had become accustomed to. Some of those features were as simple as the ability to control V-Sync in a game, and exclusive fullscreen.
In today’s patch Tuesday, Microsoft has addressed some of these complaints, and the timing of the updates are important as I will get to in a bit. First, UWP now support controllable V-Sync, as well as support for adaptive framerate displays in AMD’s FreeSync or NVIDIA’s G-SYNC. That is very important if they really want to reach for the PC gamer, since these technologies come at a price premium, and there’s no point buying a game in the Windows Store if this will not work, especially when it will work if the game is available on Steam.
The games themselves will need to be updated to support this, but since most of the games that have been released so far are either published by Microsoft, or worked on closely with Microsoft, this should happen soon.

One known caveat at this time is that people with laptops which have an integrated GPU plus a discrete GPU will not yet have the option to disable V-Sync, and Microsoft states they are working on having this available “as quickly as possible” so if you have a laptop using Optimus or Dynamic Switchable Graphics, some more waiting will be needed.
Microsoft also addressed another point in today’s news announcement. Exclusive Fullscreen is another PC quirk where a game is given unrestricted access to the display, and this was done for greater performance many years ago. UWP apps cannot access this mode though, and instead run in a borderless window. There are advantages to this method, since you can more easily multitask, but there are concerns about performance. Traditionally, you’d be at the mercy of the Desktop Window Manager to do the game rendering in a window, which is likely why V-Sync was likely an issue with UWP apps until today. Microsoft is addressing the performance though by stating that any DirectX 12 game will have identical performance in borderless windowed mode or exclusive fullscreen. Since most new games coming to the store will likely support DirectX 12, this shouldn’t be an issue then.
These changes are important for a couple of reasons. First is the timing, which I alluded to earlier. The next big update for Windows 10 is codenamed Redstone, and is due to land in the July timeframe, or about a year after Windows 10 was launched. By pushing out these changes prior to that update, it sends a message that they are not planning on being bound by major releases of Windows 10 in order to fix gaming issues. Microsoft wants Windows 10 to be a good gaming platform, so this is very important.

Even with these changes though, there are still some other issues with UWP which will need to be addressed. Since the games launch in a sandbox, tools that PC gamers are used to using such as FRAPS will no longer work, and because there is no EXE file launched, per application settings in something like the NVIDIA control panel. Mouse settings, which detect the .exe and change the button mapping, as well as macros which do the same, also will not work. The Windows Store is also missing the ability to backup games, so if you ever have to reinstall a game again, you have to download the entire game from the store, rather than restoring from a backup. Since the games we are discussing can easily be 50 or more Gigabytes, this should be an option like it is on Steam.
The timing of these updates though, which are not tied to a major Windows 10 update, are encouraging, and hopefully display that Microsoft is committed to the UWP platform for PC gaming and will update it to address issues. It’s an important step, but with major competition in this market from Steam and Origin, they won’t be able to rest on their laurels.

Just recently, Intel announced a proposal for its part in the USB-C Digital Audio specification, which is expected to be finalized in the coming weeks. Judging by our email, the first chips compliant with the new spec were announced on Tuesday by Conexant, and we asked for more information. These chips are about to hit mass production in mid Q2, therefore the first devices with USB-C Digital Audio might be expected to hit the market later this year.
Conexant introduced two new AudioSmart CODECs which are designed specifically for smartphone headsets and docking stations that use USB Type-C connection. We are told that the CX20985 and the CX20899 are to be compliant with the yet-to-be-released USB-C Digital Audio specification, and they support enterprise requirements for Skype for Business as well as meet the Android Wired Audio Headset specification. Both chips support USB 2.0 bandwidth of up to 480 Mbps, which should be enough for audio as well as additional functionality. Finally, the parts support four-conductor CTIA and OMTP headsets with up to eight buttons and can auto-detect and auto-switch between them. Since these are two very different chips with dissimilar capabilities, let’s talk about them separately.

CX20985

The Conexant CX20985 is specifically designed for headsets, but it could be used for other audio applications too. The chip integrates a stereo 24-bit DAC and stereo ADC for music and voice communication applications and supports sampling rates of up to 48 kHz. Besides this, the CX20985 has a built-in capless headphone driver that eliminates the cost and space of AC coupling capacitors. In addition, the chip sports a five-band parametric equalizer for playback, a two-band equalizer for recording, and adjustable microphone boost circuitry. The CX20985 is promoted with minimal power consumption: the specification sheets list the nominal idle current as 22.6 mA with a voltage between 4.35 and 5.25 V. The CX20985 is set to hit mass production in July and is projected to be available in 6×6 mm 50-pin QFN package.
While the CX20985 should be fine for mainstream headsets, Conexant does not expect it to be used for higher-end digital headsets. The chip does not support sampling rates higher than 48 kHz, something that their Hi-Fi audio partners and customers expect. By comparison, the CX20899 has improved DAC and power supply circuitries, which will effect the quality of analog audio.

CX20899

The Conexant CX20899 is optimized for larger devices, such as docking stations, yet it could be used to build higher-end headsets as well. This chip is considerably more advanced than the CX20985: it features a fully-fledged digital signal processor (DSP), supports sampling rates up to 96 kHz (both on DAC and ADC) as well as stereo playback path with differential line-out or capless headphone driver. The DSP fully supports functions as acoustic echo canceling, noise reduction, a programmable equalizer, digital room correction, microphone AGC (automatic gain control), volume control, and a microphone boost. The CX20899 also supports PCM/I²S and S/PDIF digital audio interfaces which should help to build docking stations for mobile devices and subsequently connections to Hi-Fi audio equipment via USB-C. The power consumption of the CP20899 is listed as a nominal idle current is 1.8 mA with a voltage is between 4.35 and 5.25 V. The chip uses a 76-pin QFN package and is currently in mass production.
Conexant was one of the early adopters of the USB Audio technologies many years ago and it is not surprising that it is also among the first to support the USB-C Digital Audio technology. Going forward, Conexant intends to introduce more sophisticated USB-C Digital Audio-compliant chips, which will enable health-monitoring headsets as well, following the wearable/health trend in the market.
Conexant does not reveal pricing of its chips for digital headsets, but typically such chips are not very expensive. For example, Conexant’s previous-generation USB Audio-compliant semiconductors for headsets cost around $1 per unit.

Today Logitech announced the Logi ZeroTouch, a new in-car mount for Android smartphones. The Logi ZeroTouch is another step in Logitech's push to diversify their product offerings and expand beyond their traditional market as a computer peripheral manufacturer.
The Logi ZeroTouch is actually two different products. Both are mounts for your Android phone that can be installed in your car. One is a clip mount that can attach to an air vent, and the other is a larger mount with a suction cup that can be put on the dashboard. Both have a magnet embedded in the back, and they communicate with your smartphone using Bluetooth LE. Most smartphones that support wireless charging should work with the system directly, as they already have embedded magnets for connecting to wireless chargers. For Android phones that don't, Logitech provides metal strips that can be attached to the back of the phone to make it work with the mount.

The goal of the ZeroTouch is to bring the features that exist in modern connected cars to older vehicles. It works with an Android app developed by Logitech. By attaching the phone to the dock, the app is automatically triggered. Logitech says that the app uses voice recognition and natural language processing to respond to queries and actions in a natural manner. You can perform actions like checking and sending messages, with incoming messages being read aloud by the application. There's also integration with popular apps like Google Maps and Waze for directions, and Spotify for music.
Logitech says that they hope to reduce the number of people texting and driving with this system. While I understand the rationale here, I'm a bit skeptical of products that take this standpoint. In my view, the best thing to do with your phone when driving is to not use it at all. While a voice-controlled app for checking and sending messages and controlling audio playback is safer than fiddling with your phone directly, I can't help but worry that these systems will entice drivers who would otherwise have not used their phone at all when driving to start doing so. Even when your phone is voice controlled, it's still a distraction from your driving. I think it'd be interesting to see companies perform some studies on the positive and negative effects of introducing voice-controlled smartphone systems in vehicles.
Both the vent clip and dashboard versions of the Logi ZeroTouch are available today. The vent clip model comes in the three colors you see above, while the dashboard mount just comes in black. They're priced at $59.99 and $79.99 respectively, and you can buy them right now directly from Logitech or from Amazon.

ASUS has introduced its flagship dual-band AC3100 wireless PCIe x1 adapter with four antennas and a maximum supported throughput of 2167 Mbps (270 MB/s). The card is powered by Broadcom’s flagship 802.11ac Wave 2 system-on-chip for Wi-Fi adapters and to show its best, it has to be connected to a router featuring another high-end Broadcom SoC.
The ASUS dual-band AC3100 wireless (PCE-AC88) PCIe adapter is based on the Broadcom BCM4366 SoC introduced early last year. The BCM4366 supports 4x4 802.11ac MU-MIMO technology and can thus use four 802.11n (2.4 GHz/5 GHz) or four 802.11ac (5 GHz) streams. The PCE-AC88 is a small half-height card that features PCIe x1 interface (the Broadcom chip supports PCIe 3.0, but exact data rate of the card is not given) and is equipped with a large big red cooler, and it is particularly large compared to other WiFi heatsinks. The device features four RP-SMA connectors for antennas as well as a special external magnetic base for the antennas which may be installed on top of a desktop PC or positioned somewhere else for better radio performance.

To actually hit the maximum bandwidth, the card has to be connected to routers powered by Broadcom’s latest Wi-Fi SoCs that support TurboQAM (256 quadrature amplitude modulation) and NitroQAM (1024 quadrature amplitude modulation) technologies. For pairing, ASUS currently offers its AC3100 (RT-AC88U) and AC5300 (RT-AC5300) routers, which support both TurboQAM and NitroQAM features. Netgear offers its Nighthawk X8 R8500 AC5300 router, which also supports maximum bandwidth up to 2167 Mbps.
The ASUS PCE-AC88 card was approved by the FCC in late November 2015, and is currently listed on ASUS’ website. The product is ready and may emerge for sale anytime, but its price is still unknown. Keeping in mind that the ASUS PCE-AC68 costs around $95, we expect the newest and fastest one to be at a higher price.
At present, the ASUS dual-band AC3100 wireless (PCE-AC88) PCIe adapter seems to be the only add-in Wi-Fi card for desktops which supports speeds up to 2167 Mbps using a 4x4 SoC. The part should come in handy for various media center PCs or NAS environments where wired Ethernet is absent but can benefit from high network speeds.

As part of the test with the Huawei Mate S, I also decided to use Huawei’s TalkBand B2 wearable which I got at the end of a press event. I have been using it for a good couple of months or more, from just before MWC. Along with the smartwatch, there is the Huawei Fit app required to digest the data it tracks.
Having never used a smartwatch-like device before, and not being enthusiastic about wearing one, I bit the bullet to at least experience it. I’ve come out the other end not completely changed, and the TalkBand B2 has a list of issues that need solving, but I have softened my opinion to smartwatches as a result.
So, the TalkBand B2: it shows the time/date, steps, calories, time slept, time biked and you can start then stop a ‘run-mode’ with it.

The display is a basic black and white affair, but sharp enough for almost all the detail you need to see on it. It’s called a TalkBand, and this means that via Bluetooth you can receive calls and minor notifications on it. The notification pop-up is not as advanced as you might think - merely showing what app or name is causing the notification, rather than any details. This is useful if the user wants to keep an eye on a certain app (I tend to keep it linked to WhatsApp and Twitter which I use several times a day, but not Skype because that is always going off).
Taking calls on the TalkBand B2 is a little odd, and I have not had much success with it. The band will vibrate as someone calls (useful when the phone needs to be silent), but then I will go find my phone to answer it forgetting that I can answer and talk on the watch. So I answer the phone, but the setup is such that it will only accept voice from the band and not the smartphone, meaning I sound muffled as I do not realize that I’m supposed to talk into the watch. Even then, because audio going in and coming out of the smartwatch is usually loud, you can’t really have a private conversation. I don’t think I’m sold on taking calls on a watch just yet.

The screen has a feature that turns itself on when it detects movement that mimics looking at a watch on your wrist. Do the motion repeatedly and it will go through the different screens on the display. However, it has a few flaws. Firstly, the flick wrist motion to see the time only seems to work about 40% of the time. Then, in broad daylight, the display is nowhere near bright enough to even see anything. But, at night, when you want the device to monitor sleep patterns, any time you turn over it turns on the display which is way too bright, either blinding yourself or a significant other at 3am. It’s not great.

On the monitoring aspects of the device, I feel that the step counter is not that great. It recorded over 66000 steps and 45 km during Mobile World Congress, but it also detected 500 steps when I was packing my suitcase the day we left. This makes me think that a step counter is better suited for the ankle perhaps. An interesting thing is the cycling detection: while at the gym on the treadmill, I will sometimes rest my hands in front of me on the heart-rate monitors while jogging/walking in a down period, but then my steps do not count and because of the arm position. As a result, the TalkBand thinks I’m cycling. So in a 45-minute run, it will detect running for 25-30 minutes and cycling for 10-15, which isn’t true, and messes up the calorie calculations. A better way perhaps to do this is via the user indicating a cycle time, similar to enabling the start of a run.

The sleep monitor works when the watch is worn in bed. The thing is, if the feature that shows the display when you rotate your wrist is enabled, the screen is far too bright at night. When not being blinded by the light, the TalkBand has a feature where during a 30-minute ‘alarm’ period set by the user (say 6:00-6:30am). If it detects the user in a light sleep mode it will vibrate to wake the person without the need for an alarm. This means that the user won’t wake from a heavy sleep, feel fresher, and it won’t wake their significant other. The downside of this is that if you are never in a light sleep during that period, the smartwatch won’t go off. That’s assuming the TalkBand has any battery left (see later). But a final word on the sleep monitor: sometimes when you take the watch off (either for comfort or to charge), it sometimes detects the lack of movement as a sleep pattern. So despite wearing it all day, if I’ve taken the watch off at some point to do the washing up, it might tell me that I slept for a couple of hours in the afternoon (which I definitely did not do).
The TalkBand B2 is a detachable module from the wristband, allowing for configurable straps. In this instance, I used the one supplied - a leather band in a silver backing. The device is easy enough to remove, and small enough to lose if you aren't too careful. On the rear is the charging port and what looks like the speaker which uses the internal open space in the wristband as an echo chamber to amplify the sound.

On the battery, this is going to be a pain point for anyone using the TalkBand B2. In order to charge it, the unit has to be removed from the clasp and the micro-USB port on the bottom used, meaning that the device cannot be used while charging (which takes around 30 mins for a full charge). For the most part, it lasts two days on a full charge. It uses more when you are exercising, up to 10% per hour, but the two days per charge means that I was always destined to either go to bed, or to the gym, on 2% battery. Even a small 15-minute window to charge it can give it enough juice for most of the day. During some of the time that I tested the device, I remembered to charge it while I was in the shower. But to put this into real world context, in March, I forgot to charge it about 20% of the time meaning it lacked sleep data collection, or for several days during April I forgot to charge it and wear it overnight.

On the data collection, the screen shots here pretty much sums it all up, telling the user how much sleep and how many steps. It is up to the user to decide what to do with the data, and I’m not sure how much might be being uploaded to a personal account. If you are trying to maintain a regular exercise and sleep schedule, it gives rough metrics that can be interpreted on whatever side your confirmation bias ends up on, but at the end of the day the only thing that makes this data collection useful is if it provides recommendations, and the TalkBand and Huawei Wear app currently do not do that. Actually, I’ll adjust that statement: if it detects you are sitting down for more than an hour, it will vibrate to tell you to stand up. Somewhat annoying when watching a film or on a long haul flight, and the time gap is not adjustable.

At the end of the day, I am glad I’ve tried the TalkBand B2. It’s not the best device for me, because of the brightness (especially at night-time) and the battery life really puts a dampener on the user experience, but it comes in a lot cheaper than the Android, watchOS or Tizen-based devices if you absolutely need a screen. If another smartwatch ever floats my way, I’ll see how that compares to this one.
