You might need to callibrate your battery as well.

Discharge your device to zero and charge it back to 100 while switched off. After that please don't let the battery fall below 20 percent and don't charge it to 100 percent often. If is based for the battery to be used under 20 percent, unless in certain unavoidable circumstances.
