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.
