Hi everyone

My iPad Air 2 battery got weak, and my volume down button stopped working.

So I bought:

- New battery $19.50

- New volume-microphone flex cable $4.00

- Pre cut adhesive strips $4.50

Installed everything with utmost care. Unfortunately I forgot to reinstall the plate that secures the cables connecting the LCD to the iPad. So I reopened the iPad, this time foolishly a tad less careful, so I ended up breaking my LCD screen.

I was devastated.

Had no choice, so ordered and installed a new one for $118.00.

Now I have the following issues:

Issue 1:

The iPad works, but every time the battery drains to zero and I charge it, it boot loops 3 - 4 times before staying turned off for a few minutes. Then boots and charges normally while staying on. But now I have this suspicion that the fully charged battery kinda drains faster than it should. It still lasts a fair bit, but I feel not as long as it should.

And in Settings > Battery, I get no battery info even after using the iPad for a few hours. It just says “Battery information will be available after using the iPad for a few minutes”

Question 1:

Are these sign of a bad/cheap or even damaged replacement battery?

Issue 2:

The new LCD screen displays waves along the left edge when holding the iPad on its left bezel in portrait mode.

On that left bezel the LCD also has a thin line of being a tiny bit dimmer.

Also I’m not sure about this, but I have a slight suspicion that this new LCD has slightly less color saturation, slightly weaker black levels, and kinda worse viewing angles with more blueshift than I think I remember.

Question 2:

Are those commonly known signs of a potentially not as good as original, cheap LCD screen? Or does it sound like a damaged screen?

Issue 3:

I have difficulties with the new LCD staying in the chassis.

I tried the seemingly quality pre cut adhesive strips, but the LCD simply keeps slowly coming off. I then diligently cut fitting strips myself from generic double sided tape we have at home. Which seems to hold in the screen a bit better, but still, the LCD keeps slowly coming off. So I currently constantly keep pressing the edges of my LCD back in to the chassis.

Question 3:

Are there specific pro-tips on how to make sure the LCD stays in the chassis? Or is it not normal for the front to slightly keep pushing out, maybe a sign of the new battery being slightly too thick? I’d really appreciate some experts advice.

Thanks in advance

Update 20.02.2019

Ok after analyzing the new screen some more I can definitely confirm that this new one has noticeably worse viewing angles and color saturation.

I figured because I have my old broken LCD still around I can simply reconnect it and quickly compare image quality.

This is my old screen:

This is my new screen:

Things like this are difficult to capture in pictures, but you can clearly see the new one is washed out in comparison.
