    Had a look about and couldn't see any other threads regarding this but wondering if anyone else has this issue? I recently upgraded from a 5C to an iPhone 6, I swear the 5C ran better on 9.2 than this iPhone 6 does .

    When you unlock the screen it stutters and is laggy, when you type its sluggish etc. I've done all the usual clear back round apps, clear the ram etc etc, this was dowloaded and installed via iTune so not an OTA update.

    This doesn't happen all the time but it does happen enough for it to be annoying.

    The 5c definitely runs 9.2.1 better than the 6. iOS 9.3 (which is currently in beta) is a lot better though. Still, the 5(c) seems to runs iOS 9 better.

    Did you do a clean setup, or import files from backup?

    My one annoyance is from time to time I really have to "close" apps to get back wifi, or switch wifi off and use cellular which works fast and better but a few apps refuse to use cellular.

    Backspace / delete can be terrible and refuse to work or act frozen and have to keep at delete key. Lack of cursor/pen and forward + del -- there is almost no ay to highlight text and copy, or drag finger to move cursor and see where what is under where finger is.

    5C is 32bit and uses OpenGL graphics API. Newer phones are 64bit and use the new Metal API in iOS9 which appears to need more performance optimisation.
