30% battery issue
Recently after updating to 4.4.2, I've been experiencing a weirdass issue.
The phone will drain normally/fast from 100% to 40%, with system_server draining the most, and then once it's at 40%, the radio will malfunction, sometimes not getting a signal and sometimes showing full bars but it actually doesn't have one.
At 30%, I cannot get any reception whatsoever, even with turning airplane mode on and off. And then a while after hitting 30%, the phone will just die instantly, no "Powering off" popup, just sudden black screen until I plug it in again, in which case it it will be partially reset in the fact that I will show the "Android is upgrading" popup and the clock and date will show 8:00 and 1/1/1970 respectively. If I manually shut the phone off, it can't be booted up again until it is plugged in.
