My STOCK Samsung Galaxy S3 (says 4G LTE on the back) updated a few weeks ago and ever since, my battery has been draining at an exceptionally fast rate! My System Info says I have Android Version 4.1.1 which, according to Google shows up as Jellybean. Since the update, my battery drains approximately 1% every ten minutes when idle. If the phone is at 100% at 11pm and I take if off the charger and check it in the morning at 6am when my alarm goes off, it is in the 50% range or lower! This is with the phone doing nothing - idle! I've been reading all over the net about people having this issue with Jellybean! Are there any easy remedies for this problem, other than resetting the phone back to stock and updating again? And does that even solve the problem in all cases? I didn't get a warranty with my carrier, so am hesitant to root my phone because that voids my manufactures warranty, but if this keeps up, I don't see any other options! Thanks for any replies ahead of time!
