Win10 PReview on SP3, horrible battery life

[dkp23]

Anybody else have battery issues with sp3 with the preview? Sat here for about 10 minutes and it has almost drained 10% doing nothing.

What Build are you using?

I carried out ​an upgrade using he 10162 ISO and have had no issues with battery life, the only slight issue is I'm not getting a very accurate time remaining with the charge. For example, I currently have 80% battery with an expected duration of 1Hr 52 Mins, but I know it will last the rest of the day.

I have the same build, just put it on two days ago. Not sure about the time, but the % declines pretty rapidly and the fan turns on faster than it use to on windows 8.1. I could watch a movie or leave it on for an hour and not have a fan come on, now, it just goes on within 10 minutes and gets pretty hot.

concerned this will overheat my device.
