This is still an issue for me. I upgrade iOS as soon as they are available in the hopes of a bugfix for the CPU scheduling. I have also suspected its a problem with the performance cores not being used for some games/applications. The most annoying thing is that while all my 2fa, work and personal setup has been transferred to the iphone 12, im still carrying around my XR to play games because there is zero issues with it. Very, Very disappointing to say the least.

Still happening on iphone 12, still perfectly fine on my old XR. Thanks apple

Ive been watching and updating iOS as soon as it comes out. The other recent updates didn't seem to make any difference however yesterdays 14.2.1 seems to have made a noticeable improvement for me. There's nothing in the patch notes about fixing any general or specific performance issues though. Hope i am not jinxing myself. Anyone else's better after iOS 14.2.1? Side note: This update isn't on my ipad pro or iphone XR (they are up to date with only 14.2) so seems to be for 12's only. Neither of those devices had any issues with the game.

I have this problem in games as well. Mostly noticeable for me in DC Legends. My old XR side by side has no lag or anything. The 12 you cant even slide the hero list, shop or gear on heroes without it stuttering and lagging really badly. The matches themselves lag horribly too. I hope this can be resolved with a software fix and is something to do with the games not using the performance cores properly and it is using the low power cores or something. Otherwise i will either go back to the XR or maybe android
