iOS 9.2 beta 4 - UI performance on 6s Plus

Spotlight from the top is now completely iPhone 6s style fluid. It was like 30fps when blurring downwards with a janky keyboard prompt but now it's 60fps easily.

3D Touch animations are slightly better, not perfect 60fps but still better than before.

Multitasking is smooth entering or exiting the feature but scrolling through suspended apps still lightly lags and the kinetics just feel off (accelerates scrolling through apps as you get closer to the edge but accelerates fasting on the right edge than the left edge etc).

Thank goodness. The UI slowdown is such a disappointment to me. I've had translucency off for the last few weeks, but it doesn't completely smooth out the os.

I am still getting slow-downs, and others in different threads have had a similar experience.

Honestly, I haven't noticed a big change from beta 2 or 3 in terms of performance.

What kind of slow downs? Spotlight animation is definitely improved and so have 3d touch ones (although sometimes it kinda reverts to the previous beta lagginess, i'm not sure why, it's weird).

They might have improved but they are not smooth. There are definitely dropped frames. They appear proper smooth on my friends 6s, but not my phone.

Yeah I'm getting similar results on my 6S Plus. Spotlight seems to be full 60fps. 3D Touch menus are probably somewhere around 30, noticeably laggy still but probably a little improved from 9.1. Task switcher also is usually 60 fps with occasional hiccups.

As with previous iOS versions these issues all resolve and run at 60 fps with Reduce Transparency enabled.

Make sure you submit feedback to Apple so they know getting proper performance is a priority to users.
