Saw the option to install it this morning and went ahead with the upgrade. All is good with (possibly) the battery life being a bit lower, which could be because of the stress of the upgrade...

Your battery life will improve,might wanna clear the cache partition if you haven't already.
Doze seems to be working very well,little to practically no battery drain with screen-off..............
Also,take advantage of the ability to fine-tune permissions on a per-app basis:
If you didn't factory reset before taking the update,you won't be prompted to do this,& you'll need to go into Settings > Application Manager then MENU in the upper right-hand corner,select App Permissions & fine-tune as desired.
This may break some apps,you'll know if they force-close,just go back & re-enable the app permissions you denied until it works again.
You can also go to the app permissions on the app itself in Settings > Application Manager & scroll through each app,you'll see Permissions,tap on it & fire away................
