One of the key features of this new phablet, besides its huge screen, is its impressive battery capacity, at 4050 mAh it is the highest available on a smartphone. When it comes to power, in addition to the hardware performance, Huawei also optimized the power consumption on the software side. According to the manufacturer, with Huawei’s patented proprietary technology Quick Power Control and Automated Discontinuous Reception (see slides from the press conference below), both the Mate and the D2 can save up to 30% power. During the press conference, the manufacturer stated that the estimated battery life for continuous video playback should be 10 hours 8 minutes and 22h 13 minutes of talk time. Huawei claims that its more than what the samsung Galaxy Note 2 can deliver (see the sldie below).: http://www.ubergizmo.com/2013/01/hands-on-huawei-ascend-mate-review/
