Same problem here. We have an activity tracking app and people lock their phones to go out with it. We have advanced tracking based on raw sensor data and this uses more than 15% CPU. IOS 14 no problem. Also IOS 15 no problem with iphone 12/13, because they have more CPU resources and we stay under this new/undocumented limit. If you google you only find the 80% limit in the official documentation. Very annoying, our app is now not working anymore expect with Guided Access. Guided access is not really a solution though since it drains the battery because the screen stays on. Any work arounds would be awesome if you know one. I'm currently testing to play some audio because maybe the % limit does not apply to audio apps.
