Battery drain after dock problems

Hello everyone,

A month ago I, using all my wisdow, cleaned my lightning dock on my iphone 5s. I screwed it with the tweezers I was using. I did not brake any pins but I really bend one of them. I fixed it pulling it back but my phone began to drain the battery. Bought a dock replacement and the phone is like before: it charges but drain the battery (in stand by) in 3 hours.

My guess: U2 IC (1610a) problem. Do you guys think the same?

Can anybody help me with some other possibilites?

Thanks a lot

It's possible that U2 was damaged; you may have shorted something with the tweezers or due to the bent pins. However, small parts, such as the Dock flex are known to suffer from poor quality so it is also possible that it is defective.

Ideally, you would want to use a known-good Dock flex to completely eliminate that as a issue. If you still have a drain issue, than a good micro-soldering repair shop would be able to properly diagnose your problem.

The new dock seems ok.... The battery drain still the same after changing the dock. Guess the problem is the U2....
