Haven't had problems with screen freezing, but I was getting some pretty subpar battery life.
It may be counter-intuitive but my battery life has Drastically
improved by turning off power saver. I don't know if the throttle up/down on cpu and brightness is too aggressive and does more harm than good or what but this was the major offender for me. My battery went from ~10 hours to ~20+ on normal usage.
Some other things I did that netted a gain before turning off power saver.
Change Settings/Wifi/Advanced/Keep Wifi on During Sleep from always to only when plugged in.
Freeze app/task for S-Search
Turn off settings / controls / motions
Turn off settings / controls / air gesture
Turn off settings / controls/ smartscreen
