This can drain the battery of a phone within a few hours....,. Usually that's not happen, since the phone looks for service and once it found the service, it's locked in and doesn't search anymore. However, for example, you put your phone in a metal locker, or you're in a basement, concealed from cell tower reception, that can cause the phone constantly look for a signal and drains the battery in no time.

ADVISE : If you are in an area, where you know you either have no service or bad service, turn the phone off if you can !!
