recalibrate it. Let it run till it dies, then recharge. Should get back up to 100%. If not, then go to Apple store.
My iPhone 4 is fully charged at 98% why
i had this problem with my 3GS. id charge it overnight to 100% and in the morning id unplug to go on with my day and it would read 99, 98 or 97%. id try to re-calibrate it but it did nothing. it didnt do it all the time at 100%, but every now and then it did. i dont have this problem with my iPhone 4 though?
