The other day I had unbelievable battery life and did not even need to charge it. Last night I fully charged the phone and today while at work I noticed the battery power has depleted by almost HALF and I have made no phone calls or anything. I checked my services application and WiFi and SSH were turned off. I do notice I have no service where I am. Is it related to this? Is it trying to find service and killing itself? Any ideas appreciated!
