I'm seeing a good improvement in battery drain during sleep since the Windows 10 and SP4 firmware updates of 1/27/2016. Battery drain during sleep was running over eight percent per hour, but after the updates it's around one percent, half of which is Cortana. I thought I had disabled her but apparently not, so I'll be researching to get her usage down too. Prior to the updates the Intel Graphics and CPU C0 usages were terrible. They've now vanished.
