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.

Also received a firmware update yesterday on my SP3, probably a variant of same.

The SP3 update was released on 1/19/2016 and is unrelated to the SP4 update. See .

Thanks, I didn't say they were related... just that I got a firmware update also. I hadn't used it in a while.

Oh I thought you did when you said "...probably a variant of same..." The change logs for firmware update for the SP3 are very different from those of the SP4, so they are not at a variant.

Ok.... I have to get back to work.
