I've had my Iphone 4s for about 6 weeks with no problems. In the last few days, my battery is losing the charge really quickly. For instance, after charging all night and making sure it was at 100%, I drove to work (20 min)-without using my phone for anything, and the charge was down to almost 80%. I'm not super tech-savvy, but I've closed everything I can that I'm not using and made sure that nothing is running constantly with no improvement. Any ideas?
Back up your iPhone in iTunes and then fully charge. Reset you iPhone and use it until it automatically shuts down (0%). Now your battery is calibrated!
