I had 76% battery before installing 2.3.6. I updated it and after rebooting my battery level suddenly said 45% battery. Then just a minute later it dropped to 14%. I rebooted and still at 14%. There's no way the battery would drain 62% over the course of <10 min. So now I don't know what to trust.
Was my battery really charged to 76% prior to updating? Is my OS now reading it incorrectly at 14%? I'm letting the battery drain completely and then recharging.
