iPhone 4S users are reporting that their device does not fully charge to 100%. Users report that their iPhones only reach 90 to 98 percent charge even though they charged their iPhones all night.
The iPhone battery may need to be recalibrated from time to time to keep the battery percent display accurate. It is recommended that you fully charge your iPhone, then completely run it down once a month to calibrate it.
