With 300 mAh more than the original battery, the charging stand for several hours longer. Upon receipt, remember to fully charge the battery, turn off the phone, to properly initialize. (4 to 5 hours even if the charging indicator tells you she is full after an hour !!!) Then do 3-4 full recharge-discharge cycles without going below 10% (if not bad for Li-ion batteries must NEVER be fully discharged) before normal use.
