iOS 9.1 was just released. That could potentially address some of this. I haven't loaded it yet, but wanted to let you know.
My 6s+ was super smooth until i did a restore.....i think it might be a 9.1 issue
My iPhone 6s Plus continues to run like "BUTTA" with iOS9.1 installed...NO PROBLEMS what so ever.
My 6s+ was lagging as soon as I switched from my 6s. When I unlocked it it was froze for maybe 2-4 seconds. After a 6 hrs it was snappy and runs like it should very snappy and am very happy with it.
I have been doing so super apple lab behind the scenes testing and have found that when unlocking the 6s plus with fingerprint reader is when having the lag issue, when using passcode or other code option there is no issue...
WOW, I'm finding there is no lag whatsoever with the fingerprint reader (Touch ID second generation), if anything it's toooo FAST.
It doesn't actually lag until after the screen unlocks. The screen unlocks really quickly, but then sometimes the screen lags after the home screen starts to display.
Oh okay....nope, I don't have that problem either. Sometimes I forget and tap the home button twice and get my credit card..LOL
Do you ever see the clock in the status bar (or the whole status bar) disappear briefly? That's a sign of it. I actually had it, then it went away and then came back after iOS 9.1 was released.
