You can get the official figure from Apple or 3U Tools. But that's less accurate.
You're probably talking of idle load. What's it under heavy load?
And how old is it? Which model? This is the first I'm hearing of an iPad Pro 10.5 with 100 cycles still being at 100%.
3U Tools doesn’t even work any more...at least mine doesn’t. That was with my Spectrum app streaming live TV, my AirPods connected, a bunch of browser tabs open, and a couple of apps in slide over. There are millions of 10.5 pros out there so why is it shocking to you? Have you surveyed them all? You keep saying you have proof that they all have bad batteries yet that isn’t possible.....
3U Tools works just fine.
I have surveyed over a dozen modern iPads, not one lived up to expectations. Not one. Including several in Apple stores, several owned by my family, and several owned by others online.
It’s not supposed to be lower. It never is for new products. That’s a sign of battery degradation.
