Battery drain, TouchID dead, warm display/LCD in locked mode

Hi all,

I have an issue with my iPad Air 2:

A few weeks ago, I did drop it. But as I remember it did still work fine for a few days.

But then, from one day to the next, it started to drain battery very quickly (in locked mode, screen off, it goes from a full charge to 0% in about 3-4 hours).

I then realized that TouchID didn't work anymore, but the home-button is functional.

The LCD display gets warm to the touch (even if locked for 1-2 hours) in the lower right corner (not directly above the home button).

I opened it up and disconnected the home-button as well as the digitizer/touch-glass. I only left the LCD connected. In that configuration the battery drain still happens and again the LCD gets warm in the lower right corner, while the battery/logic board area stays cool (I left it open with LCD flipped to the other side, so I am sure the display gets warm, not the logic board).

I guess I would have to buy a new LCD, but that is quite expensive.

Does anyone have an idea how I can further narrow down the root cause before ordering a display?

Perhaps the drop loosened a component inside the display, but it had no adverse effects for a brief period?

Soluzione Prescelta

I did order a new screen. The first one I received worked fine in terms of display and touch, but the home button was completely dead.

I got a warranty replacement sent - that one finally worked fine (including home button and touchID)

So it was indeed the display unit that was causing the battery drain and touchID to stop working properly.
