My xperia zl c6506 continuously restarts. After 4+ hours a full battery is completely drained. Events that preceded the restarts: I was not receiving any data service, contacted my carrier (tmobile), who was useless, but in trying to help me, made me hold down the "power" and "volume up" buttons for a few seconds, which did nothing (but I am wondering if that is somehow causing the restarts). RESTARTS ONLY OCCUR WHEN THE PHONE IS NOT PLUGGED IN (i.e. only when it is on battery power). On another forum, I was advised to re-download internet settings on the phone to get the data to work (settings à wireless + networks à more à internet settings). I did this and the data now works....except for the constant restarts…did the download have something to do with it….? Please help.
