What's so laggy for you guys? I was one of those hyper critical ios9 lag people too coming from 8.4.1. But iOS 9.2 is pretty good. The biggest problem in my eyes for overall usability/fluidity has been the cut off of user input during homescreen animations. Otherwise everything else feels more or less the same as 8.4.1 now. I think maybe the weather app still loads a fraction of a second slower than 8.4.1 but everything else feels about the same for app load times. What is dramatically improved for me has been safari. It's much faster and more stable with keeping tabs in memory. Mind you I'm on a regular iPhone 6. Apps in general stay in the limited memory better than they did than iOS 8.4.1 and I used that firmware a long time. If they would just allow user input during home screen animations again I'd be fully happy. I don't care if my control center drops a few frames when it gets almost open. Or if spotlight search jitters the first time you activate it. I don't use it anyway and have it turned off to speed up the device anyway. So what is dramatically lagging so bad for you guys on 9.2?! This overall feels like the best all around iOS I've used besides a few minor gripes.
Spot on. Same experience with my devices, especially since 9.2. I hardly got any stutter anymore and if I do they are now about as frequent as with iOS 8.4.1 or 7.
The animation stuff tho is so annoying, been complaining about it since the beta.
It started in 7 and got addressed in 8 and than returned in 9, arghhh.
I assume the reason they did it is because with 8 you could sometimes make things glitch out or behave weirdly, especially when doing a pinch to close gesture on iPads and than immediately start scrolling the home screen.
Still sucks tho because that delay on iPads is pretty annoying.
I also think that they could speed up the animations again. Not talking about how 8 might load an app faster, I mean the pure animation that happens when an app is opened or closed. It's nowhere near as slow as with 7.0 but I feel it could be a fraction faster without loosing the visual effect of it. I think that is a big factor in why iOS doesn't feel quite as responsive, especially coupled with the animation having priority.
