Hi, Been checking my phone status battery usage over the last week. Maps seem to be top every time, eg - this morning, had the phone doing nothing for the last 5 hours. Maps has used 36% of battery consumption. Why is this? I have everything turned off - by everything I mean you get this power button display bar - with the screen brightness and wifi, bluetooth and two other symbols (I dont know what they are / stand for, if someone could tell me?) I have all of these things turned off. Please help!
