Marshmallow: Keep Wifi on during sleep

mrmetacrisis — Mon, 14 Mar 2016 20:48:29 GMT

Hello.

I upgraded to Marshmallow today and I like it so far. One thing I've noticed is that my Wifi isn't turning off when the phone is locked and in sleep mode like it used to in Lollipop. In my phone settings, 'Keep Wifi on during sleep' is set to 'NEVER' – and yet it's staying active. Why is this? It's draining my battery unnecessarily.

Go to settings - location, tap on 3 dots and disable wifi scanning. It might help.

I already have that disabled. Wifi still remains on. There's clearly something wrong in Marshmallow that's allowing it to stay on despite it being set to never.

That shouldn't happen though. We have quite a different story now:

Can you boot in safe mode and check if the same occurs?

Well, I am not making this up. My Wifi is staying on despite me setting it to never and disabling scanning.

I understand. Can you try out my suggestion?

I tried it, Alex. When I navigated there, it was already disabled as per my previous settings, so I couldn't disable it again. Unless you wanted me to turn it on and disable it again, which I've just done. Wifi stays active.

Sorry, I've just spotted your safe mode suggestion. I'm in Safe Mode now and it's still active. In Lollipop, whenever the phone was in sleep, Wifi would turn off. Then when I used the device, Wifi would come back on after a few seconds. In Marshmallow, it's staying on all the time.

Let me try to find more about this. Thanks for trying out the suggestion.

Thanks, Alex. I appreciate the help.

@mrmetacrisis One suggestion for now: try to turn off mobile data, turn off the display and send an email or any kind of notification to your device. See if you receive it.

Hello again.

I followed the steps you suggested (disabling mobile data, disabling screen and emailing myself). After I locked the screen, I waited two minutes and used my laptop to send an email to myself. Sure enough, the email notification came through to my phone despite Keep Wifi on during sleep being set to never and Wifi scanning being set to off. I repeated this three times to make sure: same result each time. I can't be the only one whose Wifi is staying on all the time, surely. This never used to happen on Lollipop. It's not a huge battery drain, but it's one that shouldn't be happening because my settings are all set to stop this from happening. Wifi should not remain on while my phone is asleep. This seems like a bug to me.

Thank you, will keep you updated.

Thanks so much. I really appreciate it. As I said, I'm happy with Marshmallow and battery life does seem better, but this drain is annoying when my settings should stop it.

@mrmetacrisis Back to you

Can you try to reset network settings?

When u deactivate Wifi, go in Settings - WIFI - And there you have other options to disable, and then try to see if it could help !

But remember that, in this case, some minutes have to pass to let sleep Wifi

@mrmetacrisis Ok man, I will get back to you.

Re: Marshmallow: Keep Wifi on during sleep

_alexdon_ — Wed, 16 Mar 2016 12:45:23 GMT

@mrmetacrisis Ok. Another try. Turn off the display and wait a while, the phone doesn't go directly to sleep mode. Then try again to send an email.

I think, infact as I said yesterday, that must wait about 10 minutes or less ...
