Rapid Battery Drain and Heat in Sleep? It's Windows Hello

[MartyB]

I've been having a problem that others have also described: machine gets very warm while sleeping, and battery drains ridiculously fast while sleeping. I did a reset, tried installing nothing but updates, a range of things. Finally thought, maybe it's Hello. Tried it out. Windows Hello off: 87 hours of sleep, no heat buildup; Hello on: 5 hrs of sleep, heat buildup.

Even without it, I think the battery life is pretty awful, but for now I'll skip on the Hello.

Update: disabling Windows Hello works! You need to disable it using the 'remove' option and restart your machine. Presto: battery drain and heat problem solved.

I have been using Windows Hello and have not had the battery drain and heat problem you are having. I did have the problems and I stopped using Edge and switched back to IE and the problems went away. On moderate use I got 7.5 hours of battery use on moderate to heavy use and today about the same so far. My fan has not been on since I stopped using Edge.

I can verify part of this. On standby I was losing about 4% of battery per hour, and after disabling Hello this reduced to 2.5% per hour. So it's an improvement but still too much. I like Hello so I put it back on. I'm trying it with hibernation now.

The problem some of us are having is not when the machine is in use: my fan never comes on when I'm using it. Our problem has been battery drain during sleep.

As expected, the battery drain went away completely in hibernation. It took about 12 seconds for it to wake up to a functional desktop, including going through Windows Hello. So that's a downside of using hibernation rather than sleep, but I can live with it for now. Of course we are all hoping Microsoft will fix this.

Are those analysis results available within Windows?

 

[MartyB]

If you mean the table I posted. Yes. You generate the report from a commandline: powercfg /sleepstudy

It used to be WiFi was draining the battery at 10-11% per hour on the 3s. That has since been fixed.

:unhappysweat: My new SF4 is same problem. After disable WHello, battery life comes back to 7h. If using WHello, it is just 3-4h.
Thanks for your post!

Have you installed the 11/2 system update? It has significantly reduced the battery drain for me in Connected Standby.

With Hello turned off, I get numbers similar to Marty's graph. Around 700mW per hour drain, over an 8 hour period. I would like to see it lower than that.

I just did a connected standby test last night with hibernation off, Hello enabled and chrome open to cnn. In 8 hours I had 17% drain or 2.12 per hour. I'm going to post a follow up to this once I get through some forum posting issues.

I have an aditional problem, on the All settings, Accounts, Sign-in Options screen Under Windows Hello my screen says Windows Hello isn't available on this device and I believe this is because my camera IS NOT capable BUT the point being because it isn't available it DOSEN'T OFFER REMOVE and I NEED to REMOVE it because it is throwing an error on the EVENT VIEWER "Windows Hello for Business provisioning will not be launched. Device is AAD joined ( AADJ or DJ++ ): Not Tested

Local computer meets Windows hello for business hardware requirements: Not Tested
