Is there a way to use Apple diagnostic tools to check the battery health on an ipad like one can do on an iphone? My ipad pro 12.9 inch doesn't hold the charge nearly as long as it used to. I used coconutBattery and it claims that the battery is at 78.5% health which is quite low. But when I went to an authorized Apple repair store near me they checked and said it's at 87% and it needs to be at 85% before they would replace it. 78.5% vs 87% is a large discrepancy. The guy at the repair store said that it should be possible to run Apple diagnostics yourself as long as it's connected to wifi but I can't find anything online about how to do it.
