recently i have been having problems with my phone it keeps losing battery power fast and i have taken off all apps that drain power but it still loses power and also when i turn my phone off it just goes to white screen plz help
1. Try a new battery. A quick test of your old battery is to remove it, lay it flat on a table, and try to spin it. If it spins freely, it's bulging in the middle, which is bad.
2. Unmount the SD card (Settings>Storage), remove it, and reboot. A corrupt SD card can cause problems.
The newest version of CleanMaster has a list of about 50 Apps that can be disabled if you are not explicitly using them. I have disabled all but about three.
