Has anyone updated their iPhone 6s to ios 10.1? Is it easy to use? Too frightened by ios10 to update

Don’t upgrade to ios10. It’s very stuck and crashes all the time. Sometimes even the built-in camera crashes. It consumes a lot of power. It basically drains the battery. It's too obvious, and there are also software lags, no matter how many lags there are. Many of the new operations in iOS 10 really rely on 3D Touch. Both iPhone SE and iPad Pro users may be affected by this, but considering that the two devices are slightly different in positioning and purpose, the iPhone 6 and iPhone 6 Plus are the "biggest losers."
