This battery fares only a bit better than the one I just replaced, which was the original 3G iPhone battery, with approximately 20 months of life. The original battery was 1150mA/h, and the one I just got was labeled 1500mA/h. So theoretically, the new one should go longer than the original one when I purchased the iPhone, but that's absolutely not the case. The tools were weak, and won't be useful in opening the glass cover, but are helpful in separating the connectors.
