The Huawei Ascend Mate 2 does everything big. It’s a 6.1 Android mega-phone with a whopping 4050mAh battery in the back, making it potentially the longest lasting smartphone to date. For perspective, the T-Mobile Galaxy Note 2 has a 3200mAh battery -- nearly 1000 mAh less than the Mate 2 -- and it lasted 11 hours during our testing. The Mate 2 doesn’t skimp on optics either: the front-facing camera’s 5MP sensor took excellent selfies. Throw in 4G LTE support and a March arrival to the U.S. smartphone market, and you’ve got a big device with big features that will be a big problem for the competition.
