iPad Pro has bent and cracked screen

Ultimately you need to deal with Apple about this if not satisfied. Nobody here in these volunteer user forums can help with this. If the battery had swollen, the store would be able to determine that. But in the absence of any discernible defect or malfunction, the fault for damage tends to fall on the owner.

From your photo, quite honestly it looks to me like it got bent while pressed up against something? Accidental or otherwise, that would qualify as non-warranty accidental damage. It's hard to imagine a swollen battery bending it in the middle like that - swollen batteries usually manifest themselves by pushing the screen and bezel apart from the frame, and bulging out the back of the device.

Apple would offer you an out of warranty replacement. They would not even try to repair that. If you tried it yourself, the issue I think you'll find is the machined aluminum case of the iPad is, obviously, pretty thin in areas and this won't survive well being bent, then bent back again. Thin aluminum metal fatigues pretty quickly with that sort of manipulation. Also, getting it open and apart is not trivial.

There are also no OEM parts available at retail (only through repair by Apple or an Apple Authorized Service provider). So your replacement display and any other parts are going to have to be used/salvaged or otherwise suspect parts.

Also if you try to fix it, or have some shop try to, you'll then be ineligible for any Apple support if it cannot be repaired and you want to go the out of warranty replacement route with Apple.

In the end, an out of warranty replacement from Apple is likely best. You'll get a like new device (with OEM new battery and display) and it will have a minimum 90 day warranty (or reinstates the remainder of your original warranty, if that period is longer than 90 days).

I doubt you could really do it by yourself. Get a quote from a repair shop, but expect it to be quite expensive. Probably cheaper and better to get refurb from Apple.

Hi

Ask apple for a out of Warrenrty replacement

But you will need to pay part of the cost about half price of a new one .
