Buggy 6s plus

[Mr.Pooya]

Hi there.

My 6s plus on 9.2.1 is so buggy e.g all of a sudden all the effects of multitasking were gone or it freezes when i swipe left from home screen for a sec or two. Spotlight search is off.?or sometimes touch id has delay unlocking the phone. My iPhone was set as a new while doing first setup. Is anyone facing the same issue ?
In such cases i force restart my phone.
Whats wrong with ios 9.2.1 ?
And also I'm having 7-8 hours of battery life with 2 bars LTE signal is it normal ? I mostly use safari and massaging apps and music

iOS 9.2.1 is buggy; I was looking at the iPad Pro last night in a store and that had a few issues (yeah I know it's a demo unit for the tablet's specs it wasn't worthy of the asking price).

9.3 is infinitely better. Can see it being rolled out this next week.

With mine I go through and close the open apps and then it is fine, usually 20+ are showing. Thy do impact performance and functionality and maybe threads though can't see why. And to those that think 2GB RAM is enough... tried with 4GB to see the difference it makes? My Note had more and I miss that.
