Battery improvements with W10 Fall Update?

[jojoe42]

I know it's probably too early to ask, but if anyone has installed the Fall Update on their laptop/Surface and has noted any battery improvements/changes with the Fall Update it would be good to know!!! Last time I installed Windows 10 on my SP2 I lost an hour of battery life compared to 8.1, so if anyone has any news on potential improvements that would be sweet.
