Battery is new and ok. However, there is this about a normal iPhone 4s battery with 1430 mAh. That is, the 1600 mAh are an outright lie. I did not send the battery back anyway. There is probably no more battery power. To check the condition and the performance of the battery I have read with the free tool iBackupBot drew lots, and can therefore say with certainty that it is not dealing here with a battery with more power.
