Both a tablet and Android Noob here... I recently purchased a 7042-4 for my wife and she just called me stating that the battery drained overnight without her doing anything. It was at 66% when she went to sleep last night and this morning about 10 hrs later, when she went to check her email and it had powered off. At power up, it said the battery needed a recharge. My phone gets a 2% drain (if that) on the battery overnight. Is this typical/Expected? Is there anything I can do to tune the OS to use less power? My only suggestion to her was to power it off at night, but I think that it shouldn't drain that fast in standby. Thanks!
