Why does my iPhone shut down with 15% battery remaining
I just installed my new iPhone 3GS battery and reset the phone's battery gauge by draining the battery completely and recharging it for 6 hours.
However, the gauge seems to be way off now. My phone has died 3 times when the gauge indicated I still had 10-20% left. This is extremely frustrating since I don't really know how much life I really have when I'm out and away from an outlet.
Is this a good question?
