On my iPhone 5S, no noticeable change - runs buttery smooth. If it gets rid of the bugs, then great - why not update!
Comparing my iPhone 5 on 8.1.3 with my iPhone 5 on 8.2:
8.2 is slightly less sluggish and "snappier", the lag is not as noticeable and some animations are smoother. An improvement in this regard.
Not sure about battery life, so far seems the same as before for both devices
