I repaired the screen on a iPad Pro 9.7 for a customer “have been repairing iPads for over 6 years” but my first iPad Pro. It worked fine after the repair, then came back a couple days later stuck on the battery screen, it recognises the charger then just stays charging but never boots, it’s pulling between 0.15A and 0.40A depending if the screen is turned on. The battery is reading 3.6V also so not a dead battery. Opened it up and can’t see anything straight away, I can only imagine I’ve damaged the battery connection while isolating it, does anyone know if these are repaireable, and if so any guides please? Any help is appreciated! Kind regards Harry

The iPad Pro’s are harder to work on because there are no published schematics out in the wild. The logic boards are designed similarly to other existing devices but obviously they are not exactly the same. I suspect that this devices has a charge circuit issue as it has the same symptoms as fake charging. So in theory this could be a gas gauge or Tristar issue. Ask the customer what kind of charging brick they use to insure they are using an apple original brick. An experienced micro-solderer may be able to troubleshoot this but without schematics and boardviews, it’s a bit difficult.
