If it has a 250mAh battery then that is good for a continuous 1/4W transmission for 1 hour. But I imagine the batter is mainly there for the watchdog and RTC. Which is why you never have to set the clock every time you turn the phone on.

You don't need to set the clock when you turn on the phone because it gets the time from the network when it registers.

  Pull your sim and battery. Reinsert the battery and turn the phone on. The time is still there, network or not.
