Misc Issues when replacing battery? Restarting on its own and Error 29

Put in a different battery and then:

1) Phone will restart on its own intermittently

2) Show a different battery percentage every restart


3) Occasionally cause the LCD to shake in the corners

4) Will not restore via iTunes (ERROR 29)

I tried replacing the charging port, re-flowing the battery connector and cleaning the whole board.

When I place the original battery back in the device all these symptoms disappear and the device will actually restore successfully. I have tried multiple OEM batteries. This isn't the first time I have ran into this issue.

I am almost positive there is no board damage.

Any help would be wonderful.

Answer this question I have this problem too

Is this a good question?

Turns out the batteries were faulty. Brand new OEM ... APN's: 616-0580

I have never seen this issue before but sure enough when I popped in one of my used batteries the problem was solved.


I have the same problem, when I replace 4s screen it's happen.

so I replace a new batteries, but it's still 29.

If the original battery is working and no issues then it's a problem with the batteries your buying try a different battery from a different source
