I'm glad we chose to try this battery even after reading some bad reviews. We did our research on the internet and found some instructions on CALIBRATING AN EXTENDED BATTERY. We followed the instructions and this extended battery has been working a lot better than the old original battery that came with the phone - we actually wish that we had purchased this extended battery much sooner! If you need the instructions for calibrating the battery like we found, you may do the following: After installing the extended battery, with the phone turned on, charge up the battery fully until the phone tells you it's 100% fully "Charged," then unplug it and wait a moment, then plug it back in to charge it up again until it says it's 100% fully charged again. Then, unplug it and turn the phone off. After the power is completely off, plug the phone back in to the charger cord and charge it completely up with the power still off. When you get the green light for it being full charged once more, then it's time to unplug it, turn the phone on and use the phone until the power runs completely out and shuts off automatically from running out of power. Then, all you do is charge the phone completely once more and it's ready for normal usage.
