I just updated my Motorola Droid Turbo to Android 5.1 Lollipop and it's turned into a power hog. Where the battery used to last over 24 hours, now it's only five hours. I have it plugged into my computers USB port right now to charge and the battery level is actually going DOWN. Just sitting there! It's always warm, too, so it's doing something all the time. Can I reload Kit Kat?
