just installed the brand new Jelly-Bean update after i got the notification, that it is available. Installation and everything else went fine.
After a few hours i realised, that my battery status is still at 100%... i plugged in my charger to see what happens... nothing.
I plugged in the phone via USB an still, nothing happend (could not even get the phone connected to my pc).
I restarted the phone and the battery level was down to 2%... charging still not possible. I turned off the phone and plugged in the charger again. No it charges (but just in turned off state, not while it is turned on).
Any suggestions what to do now?
