We have 2 new Tracfone ZTE Valets. Android 4.1.1 Mine gets 3 days of idle battery life while my wife's gets less than one day.
Charge both, unplug and leave overnight. Mine has 96% charge in morning, hers 65%.
The battery section shows Phone Idle and Cell Standby using about 33% battery each on hers. On her phone the WIFI is listed as using about 33% as well, while mine is 5-6%.
For some reason "The Weather Channel" on mine is listed as using about 50% battery, but charge lasts days while idle. (I assume the % means it's share of the power being used, not battery capacity)
The Tracfone "My Service" app/widget on hers was stuck 'pending reply' and using relatively large amount of data (17meg) while mine used perhaps a few k data. I assume it was repeatedly calling home. Uninstall/re-install and now it gets answer, uses little data (I include this just for recent related history)
Both phones are set to "Keep wifi on while asleep NEVER". From reading this should increase data usage on cell and perhaps even increase battery drain - but it doesn't drain my phone sitting right next to hers. 3-4 bars on cell service.
I read that "Location Services" could be turning the wifi on trying to determine location. It's true all three of the location options ARE checked, but again they are also checked on mine. GPS is ON on both as well. Bluetooth OFF, screen dim.
I'm assuming something on hers is calling home/keeping wifi active. How can I find out what it might be? Just start uninstalling things one per day?
