Is Replacement Battery defect?
Replaced the battery coming with the iPhone by a new Battery received from ifixit following the the ifixit-guide.
When connecting to the charger the battery appeared on the screen showing a small red bar and a symbol similar to a lightning, but the battery won't charge.
I once more disassembeled and reassembled the IPhone checking all connectors, but no better result. No real function on Power- and Home-button.
Any suggestion what to do next?
Is this a good question?
