I have had my Droid Razr from Verizon for about 6 months now and it is running Android 4.1.2 Jelly Bean. I used to be able to go all day on my battery if I charged it every night and kept my brightness fairly low. When I looked at the battery consumption percentages, the highest user of battery was always the screen, by at least double everything else. Now all of a sudden, my phone died within 5 hours today, it was dead by noon, starting on a full charge at around 7 a.m. I havent done anything differently with it, but all of a sudden my battery consumption percentages have changed. The Android OS is now the #1 user of the battery, while almost doubling that used by the screen. I am very confused by this and would greatly appreciate if someone could tell me how to fix this and make the OS go back to its normal amount of battery consumption. It is pretty important that my phone lasts more than 5 hours a day. If anyone could help, I would greatly appreciate it. Thanks!
