Lenovo P770 Overview
The Lenovo P770 may not be the super phone we all dream of at night, but it has the battery life we have been begging for since smartphones came to the market. Its 3500 mAh will not have you looking around for a power outlet, as it should last more than a full day. Other specs include a 1.2 GHz dual-core processor, 1 GB of RAM and a 4.5-inch display (960x540).
Sadly, this phone will probably not make it outside of Asia, so you might have to go with the Motorola DROID RAZR Maxx HD for crazy battery life.
