Not rooted, T-Mobile, i was in the middle of texting, no other background apps running, 4.3, i performed a soft reboot a few days ago so the phone was perfectly fine performance-wise, used the htc cable it comes with.
At the time the amber light was not on or anything. Just now, it turned on. It was charging for 15 minutes, and it showed 0% for like minutes with the battery meter filling up. then i tried turning it on, and it came on. It's on and charging. But I appreciate you trying to help, I think you helped with the soft reboot because i couldn't access my messages the other day. Thank you.
