My past and current experiences with #iPad: Mini battery lasts for about 2 years (maybe a bit over) I’m currently on my third mini now, bought mid-last year. Never had a regular one.
iPad pro original 12.9”: it’ll be a decade old in about 2 months. Apple crippled the OS on that in stupid ways and no new update is coming through. I had some battery problems last year, but charging fine now, but battery gets depleted fast. Currently typing on that and it sucks. Also got original 11” for family.
