I updated to the latest firmware version as prompt to me by the phone 6.1.A.2.55... (But it didn't pormpt me the update the new theme again, I had the new theme at the old firmware but not with the new one, anyone has it with the new firmware update?) Everyting was OK for 7 days now until last night... Today my phone was overheating and the battery was totaly depleated in 4hrs after I charge it all night (100% full charge). What now? I'm currently recharging the phone by USB over a PC...
Power down and turn on your phone when the phone is over heating.. that solves the issue temporarily .. but if you reset your phone and do a fresh start that issue gets solved permanently at least for me .. but do give it a try.
