I'm used to the fast battery drain on this phone, but today it started acting up. I charged it at work to 100%, I took it off the charger and immediately it dropped to 99%, 15-20 seconds later, 98%, a few seconds later, 97%. It's slowed down a little, but it's been 8 minutes and I'm at 92%. Nothing major running in the background, brightness is around 40%. I can't figure this out. I did a soft restart, still rapidly draining. Thoughts?
