Bought this as a cheaper option to replace broken Ipad Air3. Set it up so that it looks and appears just the same (once the cloud had done its job), and so just like having the old one back. Except the finger ID works properly on this one. So very happy, but for one thing. At my usual use, with the same apps, the old IpadAir would last 2 days before needing a recharge. This one is unplugged at 100%, do a few jobs (maybe 2 or 3 hours), battery empty. Can't really trust using it anywhere without a backup power source. Not sure how this is 80% minimum of a full life battery. But wont send back because so much is set up on it again and that would be a stress. The one upside to the battery is that it does charge up fully in about half the time the old one did using the same cables. Glad I saved money to get something that seems to work well overall, but the battery is a frustration.
