The tale of this phone's performance and battery life is one you could comfortably call Beauty and the Beast.

The bad news is that the performance of the Acend Mate doesn't live up to the sum of its parts. The Huawi K2V3 quad-core processor just doesn't cut it, and the user experience is frequently marred by extended pauses and general lagginess.

This lag is most obvious when opening and closing apps, and is also noticable when switching between homescreens. Even tasks like loading images in the Gallery takes much longer on the Huawei than it does on other phones with similar specs.

After running a number of benchmark tests, the problem seems to be in the way the phone deals with graphics processing. It performs well in tests that focus on number crunching and web-based processes, but once complex 3D graphics are involved, the performance dips.

On the flip side, the battery life in the Ascend Mate is outstanding. One of our tests involves loading web pages continuously on a Wi-Fi connection. Most phones last for between 4 - 5 hours, but the Mate lasted for an impressive 7 hours and 6 minutes.

Anecdotally, this equates to two full business days use, though your milage may vary depending on how you use it.
