I followed all the net instructions on saving battery, on turning off unwanted app use, etc. Google Play has 11 processes running, and I have no idea what they do. I reboot, I turn off sync, I follow the direction, but why suddenly (in the last month or two) is Google play eating my battery? I have installed no new apps, my AT&T HTC M8 is as updated as AT&T allows (5.0.2 software) etc. My phone used to last me two days on a charge (I don't use it a lot), but lately I get a day, max. Google Play and Android system use almost 50% of the battery. I can't turn Carrier IQ off for long, it always comes back, sort of like the clap. HELP!!!!
