Camera Performance
The Mate 7 sports the same camera setup as the Honor 6. I've already determined for that device that the quality suffers quite a bit due to what seems to be very poor ISP performance.
For all practical purposes, I don't see any improvement in quality in the Mate 7. The device is still very lack-luster in the camera department.

During day-light shots we see the same lack of detail as found on the Honor 6. It's a pity that Huawei didn't manage to improve the processing here as the camera should have been able to produce better results based on the Sony IMX214 sensor. The HDR shots similarly see a colour balance issue as the image loses saturation.

In night-time shots again the Mate 7 underperforms. Under dark conditions where other flagship phones would at least capture the scene in some reasonable manner, the Mate 7, like the Honor 6 will be hard to recognize what it is you took a shot of.
The camera application provides a fresh new UI that looks fantastic. But the problem here is that I find the usability has taken a toll, as previously easily available settings are now hidden behind various sub-menus.
In the end the still-picture performance of the Mate 7 is rather lackluster and competitor devices such as the Note 4 are on a completely other level in terms of picture quality. Huawei has a lot of progress to do if they wish to compete in the camera department.
In the standard 1080p mode we get a 24Mbps AVC Baseline@L4.0 video stream at 25fps with 96Kbps stereo AAC audio. The video is sharp and fluid, albeit the colours are a tad oversaturated. It's the lack of any kind of stabilization is very obvious and the video is very shaky. Again the device offers excellent video audio quality capture which is I think one of the best out there.
When turning on the electronic image stabilization the quality of the video dramatically decreases. We see a big reduction in the details of the video and what should be 1080p turns into something inferior to 720p. It's pretty obvious what's going on here: Instead of increasing the capture frame beyond 1080p on the image sensor, Huawei is retaining the 1080p capture frame and then reduces the actual video window inside of the frame and reserves the margins needed for the EIS to operate. The video window is then upscaled again to 1080p, resulting in a blurry image and loss of detail. The effect also reduces the field-of-view of the camera.
The 720p video with both HDR and EIS is even worse off. We go down to a 14.4Mbps AVC video stream on a custom encoding profile, while retaining the audio track quality. Here the resulting image resembles more what a 480p recording would produce. I've determined that this is solely due to a badly performing ISP on the Kirin SoCs.
NAND Performance
The Mate 7 employs the same Toshiba eMMC solution as found on the Honor 6. There's not much to say here other than the performance being outright horrible and unacceptable for a 2014 product. Although the model number of the chip is the same as on the Honor 6, it still manages to underperform what was already a device which was bottoming out our benchmark suite.
Competing flagships such as the Note 4 manage to outperform the Mate 7 by a hefty factor of 4 or 5 throughout all the tests. Surprisingly I don't seem to see the effect of this too much in everyday usage, but this might just be my subjective bias.

Ach, and that storage performance...Yup, all interest gone.massig93 - Tuesday, December 2, 2014 - link
Thanks for the great review! I'm so thankful you review products that are noto exclusively Samsungs, Apples or HTCs. I'd love to see more chinese phones reviews on anandtech (Xiaomi Mi4, Meizu MX4, Nubia Z7, Nubia X6, Huawei Honor X1)protomech - Tuesday, December 2, 2014 - link
Any comments on wifi performance? No 802.11ac so not expecting much.The Ascend Mate 2 was an interesting device: inexpensive and fantastic battery life, due to the 2011-class resolution and SOC performance. If you wanted a physically large display and were okay with the lower performance then it was easy to recommend.
There's no reason to recommend this phone.

I'm still lacking the proper equipment for Wifi tests, but from what I can see the Wifi reception and performance didn't change from the Honor 6.alfredska - Tuesday, December 2, 2014 - link
Especially for Android devices, it would be great if you could spend more time discussing a manufacturer's historical commitment to long-term support on their products. This includes: how regularly a product receives OTA updates; how recent the base operating system is (version of Android); whether kernel source is released in a timely manner following each update.In the case of Huawei, I'm very leary, because their first US phone offering, the Mate 2 which was just released this year, still runs Jellybean. While they claim a Lollipop is in its future, this only came after a barrage of harassment from users complaining about abandoned support. Even then, I don't want to give them praise until the update actually exists.

Huawei has been caught numerous times straight up stealing other company's intellectual property. They deployed an exact copy errata and all of Cisco's IOS in their routers. They are in a lawsuit with T-Mobile for corporate espionage. They also got caught siphoning non-anonymous user data from their cell phones and then they lied about doing it. Huawei is a government sponsored corporation and the Chinese government uses it to do whatever they want. I wouldn't anywhere near any Huawei product.pgari - Tuesday, December 2, 2014 - link
The performance charts should have included the Nexus 6 and OnePlus One results, which have already been reviewed by Anandtechpichemanu - Tuesday, December 2, 2014 - link
Hi, just today I read another review and they didn't encounter any overheating nor did they have problems in low light photography. Also the autonomy was quite good (5h of gaming if I recall correctly)Is the terminal you reviewed on the latest firmware? Maybe a defective unit or another hw revision could explain this.
Andrei Frumusanu - Tuesday, December 2, 2014 - link
It was on the a late October released firmware.I'm getting the same gaming battery life of 5h (5.6h!) as pointed out in the review, I don't think there's changes in that regard.

Sorry for the gaming autonomy number, I mistakenly remembered around 2h.
