After a few weeks I have to admit bitterly that fast this battery (the not already looked like virgin) loses its power. In normal use, the battery is flat in the afternoon. The iPhone can display only 20% charge capacity. Before 10% are reported, the device switches off completely already. The re-charging gear requires an eternity until the device switches on again. NOT BUY recommendation and probably no original battery (at least no new!). The former original battery had after 5 years still far better than this offer here!
