Keeps restarting after battery replacement

"It SOUNDS like a battery issue.

I've seen that with iPhones as well. When the battery goes bad or is faulty it jumps around in %'s and then can die randomly. Not sure about the logic board, but I can't imagine that's not bad."

"i have the same problem. it is twofold.

-keeps rebooting itself after 3-6 minutes of being turned on.

-when plugged into the wall, an overnight charge only restores charge from 0 to 75%- it shoud fully charge in a couple of hours!

while all this is happening, it is downloading and installing the latest ios version!

so maybe replace the motherboard will fix the problem?"

"I recently replaced the battery of an Ipad 3 4G using a ""non-apple"" battery, and experienced the same problem. The Ipad did not recognise the battery level, and rebooted every 2-3 minutes. After every reboot it showed a different battery level, and on the lock screen it didn't show that it was plugged to a charger. So obviously it had to do with the battery gauge...

After making sure no damage occurred while working on the iPad, (Motherboard) I ordered an original Apple Battery and replaced the non original.

That solved the problem immediately, now it's charging without reboot and everything went back to normal."

I found what causes the problem you are describing. Next to the battery connection on the motherboard. There are 6 resistors. When disconnecting the battery it is easy to displace one.(as I did) as soon as you power on and run for awhile the OS checks the battery level the pad reboots and then the percentage of battery life changes.

Have you fixed your problem? I have the same issue and I do not know how to fix the ribbon cable.
