Performance on my iPad Air has always been "slightly" slower than my previous 5s and my 6. iPads have to render more pixels than iPhones, so this is no surprise. I decided to do a clean install of iOS 8.1.1 to regain some of the speed I was missing. While playing with various settings, I decided to turn on "Reduce Transparency". To my delight, I've noticed a boost in OS animations. Here are some examples: - I can now click Safari's omnibar and there is a clean transition to my available bookmarks. Previously, there would be a slight delay and a jerky animation. - Messages scrolling seems quicker - Safari scrolling seems, eh, snappier - The keyboard appears more quickly and I experience less "typing lag" - Spotlight search is now seamless I have a meticulous eye for this kind of stuff, so don't be alarmed if you don't notice a difference. I, for one, am happy I experimented with my settings to figure this out. My iPad feels similar to the iPad Air 2 I toyed with at the Apple Store. Anyone else notice an improvement with Reduce Transparency? I haven't tried, but I'd bet this works on other iOS 8 variants.
