1:06 Didn’t work out for me. Didn’t see where you removed the four screws that hold in the digitizer.

Because the LCD screen and digitiser glass panel of the iPad 6th generation is not laminated, it’s not recommended to do DIY to replace the battery, there are big chances of getting tiny bits of dusts or fluffs inside the screen and made it look like dead pixels. … iPad Air 2 has laminated screens, that means the digitiser and the LCD screen are in one piece after taking the iPad apart, so unlike the iPad 6th generation as seen in this video. Over a year ago I kept it in mind not to buy repaired iPad 6th generation, but this year ended up buying one used, and the seller had replaced the screen, it has 4 tiny bits inside the screen!

F*ck that!

where do I get this battery

Actually we don't need take apart too many thing like that, you may damaged the ipad
