iPad Pro 9.7 Charging Stuck at 1% After Screen Repair

Problem Description

We’re starting common problem with these iPad Pro 9.7 tablets after a screen repair.  It seems as though Apple decided to hold the logic board in place with some pretty sticky adhesive, which makes it very hard to isolate the battery during a screen repair.  Ultimately, the technician sticks a guitar pick underneath the battery connector, like they’ve been taught all of these years, but damages the battery connector pins.

Some of the common symptoms are as follows:

  • No Charging
  • No Power
  • Battery Stuck at 1%

Inspecting the battery connector under a microscope, you can see that the 5 pins have a ridge on them, which makes it even more prone to damage.

Depending on which pin or pins are damaged, then you will see one of the problems specified above.

Repair

The repair process is as follows.

  1. Disassemble the logic board.  The hardest part in this step is removing the top part of the logic board without damaging the flex below it.  The whole thing is held in place with some very strong adhesive and the adhesive sticks to logic board flex and the flex below.  It’s awful.
  2. Remove the black tape from the bottom of the battery connector and desolder the 9 solder joints with the help of some low melt solder.  Use your tweezers to push down on the solder joints.
  3. Resolder the new battery connector.  This should be simple through hole soldering.  Just make sure that you use ample flux.

Audio IC iPhone 7 Loop Disease Repair w/Lifetime Warranty

Recently, several articles have been released on the problem plaguing the iPhone 7 and iPhone 7+ called Loop Disease, also known as Audio IC iPhone 7 disease.  This problem usually results in audio problems.

Essentially, the mic and speaker functions will stop working for no apparent reason.  The red button under voice memos will be grayed out.  Also, the caller can’t hear the person on the other end and vice versa.  Depending on the iOS version, maybe you’ll get a grayed out speaker.   You might get something like this:

You might also have an iPhone where the phone is stuck on the Apple logo, but you can feel the vibration of the home button.

Update 12/10/2018

In iOS 12, you’ll see this error message (Recording Failed) when you try to record a voice memo.

Loop disease is becoming an ever increasing problem, especially since these iPhone 7/7+ phones are coming off of their 1-year warranty.  Once again, instead of addressing the issue, Apple has decided that the best course of action is to just ignore the issue and hope that customers pay $600 – $1,000 to upgrade to a newer version of one of their phones

Here at Microsoldering.com, we’ve known about this problem for a while now.  The problem is that due to the bending of the logic board or a hard drop, a pad under the chip that handles the audio on the iPhone becomes disconnected from the logic board.

The logic board is missing a silver pad

Every pad under a chip is designated by a letter proceeded by a number.  This missing pad under the audio IC is known as c12.  To fix this problem, we must disassemble the iPhone down to the logic board, then remove this chip, run a microjumper, and reball and replace the chip.  You can watch a video of the repair here:
