Last week another poster here noticed frame rate drops in certain games. For example, he mentioned Crossy Road. I can confirm that there are occasional hiccups in that game on my Mini 4. However after a week, I have played a few more games, and have noticed more frame rate drops. For example, Sword of Xolan will sometimes become a little choppy (looks like it's dropping from 60fps to 30fps). Also noticed similar choppiness in ShadowBlade. I have tried various settings changes, including turning off most background refreshing of apps. The framerate drops still happen. Anyone else notice similar performance issues during games or other graphical apps? I think the Mini 4 hardware should be capable of running these games at a constant 60fps easily, and can't quite figure out why it's doing this. FWIW my Mini 4 is updated to iOS 9.1.
