Pretty much the thread title. I'm running 9.3.3 on my main iPhone (a standard 6s) with excellent battery life and performance (92% battery capacity, it has never been exchanged; I'm getting 8-9 hours of on-screen usage with light use, and 6-7 with high brightness and LTE, and heavier usage). Not much to say about performance, it's excellent with no bugs at all. App compatibility is still fine and however little I can't download doesn't bother me yet. Anyone on iOS 9 on the 6s/6s+?
