Software - EmotionUI 4.0

The Mate 8 is the first Huawei device to ship with Android 6.0 Marshmallow. As in the past, Huawei tries to improve and differentiate from stock Android by including a customized UI that tries to introduce some larger UI changes as well as functionality. The newest iteration of Huawei’s skin, called EmotionUI, reaches version 4.0 and is an evolution of EmotionUI 3.1 that we’ve seen on the P8 and Mate S.

 

 

In terms of design we see a continuation of a frosted translucent black notification shade and quick-settings drop-down panels. Here we didn’t see much change compared to EmotionUI 3.1. I appreciated the look that was introduced on the P8 and as such don’t see much need to change what is otherwise a clean interface.

I did notice that Huawei changed the drop-down behaviour when swiping down the notification shade; in the past you’d have to swipe down with two fingers to get to the quick-settings view, while one finger swipe naturally opened up the notification view. The difference in behaviour now is that when you don’t have any notifications available, a one finger swipe will open up the quick settings panel instead of the notification shade, a change that made sense to me and I somehow appreciated with continuous usage.

An extremely large improvement and change to a nagging UI choice in EmotionUI 3.x is the task switcher. Huawei has thankfully abandoned the 4-tile paginated preview UI in favour of a more stock-ish continuous scrolling linear layout. The difference here is that instead of having vertically stacked previews of the apps, we see full-screen previews that are arranged horizontally. This allows Huawei to still keep the gestures (swiping down on a preview) for “locking” an app from being killed by memory management. Swiping up will still kill the application.

The video above was recorded via the system built-in recording function. Beyond the already existing option to draw letters or figures with your knuckle and bind them to shortcuts to applications, Huawei introduced the option to take a screenshot with a double-tap with one knuckle, or to trigger video recording with a double-tap with two knuckles. The resulting video format is 720p at 18fps with a bitrate of 2.7Mbps, which is not quite of the best quality but at least serves its function and is storage friendly.

On past year’s devices I mentioned that the overzealous power manager’s (Power Usage Firewall) default settings resulted in a lot of warning notifications of power-hungry apps running in the background. On EmotionUI 4.0 I haven’t seen a single such warning as it seems Huawei has greatly toned down the default warning thresholds. Unless an application is “locked” or protected via the task manager interface, the system kills applications once the device is suspended, even if they acquire wake-locks. The feature that can be positive to disarm badly designed applications which might drain battery life in the background, but definitely needs to getting used to when coming from other Android implementations following the default memory management behaviour.

 

Further large UI changes can be found in the settings page where Huawei has drastically cut down on the amount of items in the main settings view, rearranging a lot of the usual configuration categories in sub-menus. The “Advanced settings” sub-menu has become a collection of the least accessed settings, which oddly enough also now includes the Battery Manager page which further also hides the classic “Consumption level” page in a further sub-menu. Android’s battery consumption statistics are just estimates than are often very inaccurate so I’m glad that Huawei buried the misleading numbers away from the average user, but I still would have liked to see at least a more accessible device battery lifetime and screen-on time statistic at higher level somewhere in the settings.

 

 
Large vs small view mode

Because the Mate series and phablets in general come with such large displays I’m always disappointed to see manufacturers not actually take advantage of the screen estate and ship the devices with an appropriate UI density that allows for more content on a given screen area. This was a problem for the Mate 7 and something that I also immediately picked up on on the Mate 8.

Thankfully a new feature of EmotionUI 4.0 is the ability to change the system’s global DPI settings. Found under the display settings, the “View mode” page allows to choose between three different density settings that scale all interface elements system-wide. Changing the setting requires a reboot for it to take effect. At the highest density the Mate 8’s UI elements are roughly the same size as found on the Nexus 6P, but with the advantage of having a larger screen area. Looking back at the Mate S I now realize that it’s something I didn’t pick up on while reviewing the phone, and Huawei’s past device would definitely benefit from higher density interfaces and inclusion of this new feature. I would more than welcome other vendors to include configurable DPI settings as it can greatly improve a device’s screen experience, which is by the way also something that isn’t solely limited to large screen devices.

 

In terms of system applications there hasn’t been much change in EmotionUI 4.0. All default apps are very functional and work well. The Mate 8 hasn’t lost any of the additional features that were introduced with past devices and that’s not a negative thing either. Even though themes are available, they are just able to change icon packs and colour accents in applications. There is still a lot of white in the UI of the system apps, something we saw introduced in Huawei’s larger UI overhaul in EmotionUI 3.0. It may have been interesting to see a switch to the more modern navigation and button schemes that were introduced with Android 5.0.

One particular design choice that still doesn’t go well with me personally is the default launcher and the normalized icon frames that try to mimic iOS’s style. This together with the fact that there is no application drawer inclines me to quickly drop the stock launcher in favour of a third-party one, which thankfully is an option and works without any issues.

 

I’ve liked EmotionUI in past reviews and the Mate 8 is able to make some evolutionary improvements that is able to fix some of the more outstanding critique points found in past devices. I’m definitely happy that Huawei finally changed the multi-tasking UI as it makes for much more fluid and ergonomic usage, something which was definitely a problem with last year’s Mate 7 and to a lesser extent smaller form-factor devices such as the P8.

In terms of performance Huawei and particularly HiSilicon seem to have made very large improvement to the Android codebase. This was one of the talking points during HiSilicon’s presentation of the Kirin 950 and how the new BSP software improves on things such as touch latency and application launch time. This seems to have very visible and immediately noticeable results as the Mate 8 is by far the fastest Android device I’ve come to use to date. When turning off all system animations it becomes visible that when switching between applications the Mate 8 is able to respond much faster than for example the Nexus 6P or Galaxy Note 5.

All in all the Mate 8’s software is very good. Any subjective design elements such as the launcher are replaceable, while the rest of the UI is clean and attractive, although one can still fine some older design elements related to the system applications. It’s definitely in regards to performance that Huawei was able to impress as it’s something I didn’t expect at all and actually puts the performance of other Android devices in perspective, so I hope Google and other vendors are closely paying attention to the improvements made on the Mate 8.

    Wow, the efficiency of the A72 seems the best out of any CPU.
    If I'm not mistaken, it consumes less than 50% of what the Apple Twister in iPhones needs

    Read my comments above.
    The SPEC numbers seem tainted and untrustworthy. I wouldn't trust them in the slightest until AnandTech (or someone else) has had a chance to validate them. In particular the vpr number still seems unlikely.

    As for your efficiency of A72, I don't know where you're getting that claim from. In particular the sort of fine-grained per-core power data needed to make the determination has not been made available for iOS. The best we can do is macro-level tests like the WiFi and LTE battery life tests, and obviously iPhone does fine on those. (Which is not to denigrate ARM/TSMC/Huawei's achievement --- this does look like a very nice CPU, unlike the somewhat more problematic A57.)

    I made sure all the tests passed validation so the scores should be correct this time around. Reply

    Disappointed to not see the OnePlus 2 in the benchmarks, seeing as it's a dual SIM phone as well. Reply

    What smartphone sites and reviewers doing wrong is comparing two completely different systems which is VERY WRONG and misleading to the ppl on internet !!!
    It is simply inapplicable ! If Apple would manufacture their iphone with android system then their pone wouldn't even start .. ! And it would be MEGA slow But IF iOS for iphone would be on an android (latest) device , you would not even realize when the phone iOS booted to home screen..
    That is the FACT ! The main reason is that android is and true operating system where are 5x more processes than on poor simple iOS which is just the ''shell'' system.. there are no many processes in background as on android system.. android is linux which is VERY VERY similar to Desktop PC linux.. AND THAT is WHY Apple DENIED put iphone's iOS onto MACs or MacBook PROs or OSX onto iphones !!
    There is ''behind the scenes'' big game around and about this ''secret'' Apple's software but unfort. many ppl HAS NO IDEA unfortunately ! ..

    You appear to have misplaced your tinfoil hat. There is no reason android wouldn't run on an iPhone if Apple decided to do that. Literally no reason. It also wouldn't be MEGA slow, since the a9 is one of the finest SoCs ever made. The rest of your post appears to be uninformed dribble and garbage. Reply

    OK u unknowledged person I won't be even bothering with you .. who DOESN'T understands the reality which is in the world.. A9 finest ? pleease .. you are so stupid bcos u believe media and advertise marketing.. and maybe fake benchmarks when it comes to iphone .. such common person you are.. live you in your dreams.. ;) Reply

    Well, since you claim that the tests for the a9 are fake, you mind sharing tests of your own? Reply
