Presently, I have an iPad mini 4 and a Sixth Generation iPod touch. Both are still on iOS 9. I have an iPad mini 2 set to run new versions of the iOS Public Betas (and is therefore running the latest iOS 10.3.2 Public Beta) and I have a 12.9" iPad Pro running the most current public release of iOS (so, 10.3.1, as of this posting). The mini 2 runs an A7 (similar if not identical to the one in the iPhone 5s). The Pro runs an A9X (and, given that I'm on the 12.9" Pro and not the 9.7" Pro, supposedly a beefy one at that). The iPad Pro runs iOS 10 with smooth performance. The iPad mini 2 can be laggy. Considering it's a one-way jump, I'm curious. How is performance with A8 devices (such as my mini 4 and sixth generation touch)? There's a world of difference between how iOS 10 runs on my 12.9" iPad Pro compared to my iPad mini 2. So, I'm wondering where in that range my A8 devices fall. Ultimately, there are many things in iOS 10 that I utterly detest, so holding off on updating (especially since I still have devices running the current version) is working out okay for me so far. But if iOS 11 comes out and fixes most of my grievances, I'll give thought to updating. But if iOS 10 is already making these older A8 devices show their age, perhaps that might not be the best? I remember reading that the A8 in the sixth generation iPod touch was the closest of all the A8 devices to the A7 in terms of performance, so I'd imagine I'll feel the sluggishness more there. The A8 in the iPad mini 4 might fare better given its 2GB of RAM, but I suppose RAM isn't EVERYTHING when it comes to iOS. Anyway, if any of you have any educated insight on this, I'd love to hear it. I'm probably not making the jump to iOS 10 on those devices, but if 10 doesn't slow them down noticeably, I might give thought to moving them to iOS 11 later (assuming Apple fixes the glitches that plague iOS 10).
