I know how you feel, I had to replace my first iPad, but not because of a failing battery, but because it was an older model and at its maximum software update; so technically I upgraded my iPad

Did it have a home button?

My old iPad? Yeah it did

Our first iPad Air 2 had the same issue, and with a home button too, btw... We changed it to a Galaxy Tab S8 Ultra and tadaaaaaaaa....

i'm still using my iPad Pro 12.9, the 2017 edition.
battery is okay-ish , it gave me some mini heart attacks during the past 2 years, where it was too cold for it to charge or for some reason had to flip and insert the cable for it to charge xD
Cheers and good luck with the new iPad
