Xperia III running the latest update.
About 10 days ago I noticed my battery didn’t make a day. Plugged it in, came back an hour later and it had fully discharged. Put it on a different charger, charged to 100%, went on. Plugged it in that night and when I got up the next morning it had been discharging, not charging.
Happened a couple more times mixed in wtih a few days of no issue. Now I notice it only charges when the phone is turned completely off.
This leads me to believe this is a software glitch of some sort, but I have no idea who, what, where, or when to even begin looking.
Anybody have the same issue or a suggestion for a fix that does not include "reflash the OS’?
