I've heard of people going into subways or areas with low coverage and the battery of their phone taking a hit. The phone should know where these areas are and take corrective action not to drain the battery. Now in an emergency, you hope the phone will jump like hell between the networks so you can receive reception to place a call and get help if necessary.
