Hat geantwortet auf: iPhone battery not charging after DIY battery replacement. Why?Has a similar issue, posting it here to help in case someone is facing the same thing: I noticed that my battery was charging fine with the little battery port cover removed, but as soon as I screwed the cover on, the battery wouldn't charge, even though the iPhone was indicating that charging is in progress. Figured that it must be some electrical issue, and upon closer inspection, I saw the plastic insulator on top of the battery connector was flaking off. So I put a little piece of plastic tape on top of the connector and screwed the cover back on. The battery is now charging fine, I suspect the cover was causing a short with the connector that allowed the charging current to escape.
