Running .211 while rooted. Three weeks ago, my battery started doing this thing where it would last 5 hours then get to 50%, then just drop to 5% then last another hour then die. Today it will now die after only 10 minutes even though it is fully charge. I have tried the following to trouble shoot: downloaded GSam Battery Monitor. The number 1 drain on the battery is the Kernel. Did a battery calibration with stock cable and charger. factory reset....not fixed. Last resort: Reverting to stock, unrooted .211 or updating to the leaked .215. Verizon is willing to do a warranty replacement but since I'm rooted, I fear they will charge me for the cost of replacing the phone. Has anyone has this ridiculously rapid battery drain issue?
