It seems that the battery only drains when it is within range of a cell tower.

Another commenter speculated that when you're out of service, the software correctly identifies that there is no tower to connect to and stops trying. But when you're in service, the code repeatedly tries to do the 3G handshake because it can see a valid tower.

This would explain why mine's been mostly fine since I moved to a place with an underground garage. Now I park 4 floors underground and the battery has only died once in the last two years.
