Don’t want to jinx myself, but whatever Apple did with iOS 11.3, it has made my iPad Pro 10.5 and iPhone SE SOOO much better. I’ve been frustrated with constant animation jitter, lag, UI stutter since iOS 11.0, and it drove me crazy all this being rendered on a 120hz screen. Kudos to Apple.
It’s not been long enough to really notice yet but hopefully they’ve also fixed the terrible iOS 11 battery drain. Fingers crossed.
