The battery life on my iPhone is great. I get about 6 hours or more of use between talking and edge (very little wifi) and about 3 days of Standby. The only thing is that once my battery indicator goes less than halfway, its depletes rapidly. Once I hit 20% it gets to 10 % within an hour of standby and from 10% to 0 within 30 minutes. Is there any reason why this is happening? Like I said, the total time is great, but the indicator meter appears to be incorrect.
