How long should I charge my S3 extended life battery?
Depending on the size of your battery we recommend 9 to 10 hours of consecutive charging. If your battery is 4500mah or higher you would want to charge your battery for at least 8-10 hours. Even when it says that it is fully charged, keep charging overnight. If you don't the battery will show that it is draining quickly.
Your phone will take a little while to adjust to the new battery capacity. The phone will think that it is fully charged but it is not. The battery will slowly charge the rest of the way all night.

Why is my Galaxy S3 extended battery not holding a charge?
The most common reason a battery doesn't seem to be holding a charge is due to the battery not being charged the proper amount. This is the reason about 95% of the time. The other could be a bad charger, a low-quality cable, or keeping your phone in a really high or really low temperature environment.
