Just replaced battery but not holding a charge.
I just purchased an ifixit replacement battery to exchange for the dead battery in my wife's iPhone 6. Out of the box it charged up and my wife used it. That night she did not plug it in (the connector she plugged her phone into was not connected to an actual charger.) Anyway, after hours of being plugged in, the phone indicated that it took a charge, was at 100% and powered on. She just yelled down to tell me that it has no power and has no charge - just the low battery indicator and the animation saying to plug it in. Is there some mistake I could have made during installation that it would only last for one cycle?
Is this a good question?
