Replaced the battery on my iPad 3 today due to the old battery not charging. The problem I am having is after I replaced the battery the iPad now continuously connects and disconnects while plugged in. I have triple checked all of the connections and everything is plugged in properly and all connections are clean. Any idea as to why this is happening?
When you say you have triple checked the connections, have you checked to make sure the contacts on the battery are making a good connection to the motherboard? Did you test the charging and functionality before closing the iPad back up?
Sounds like it might not have been the battery that was the culprit in the first place. Do you have a new charging port to try? Worst case scenario it might be an IC issue, more specifically the U2 IC might be fried.
