Kernel and Android system using more battery % than screen

[quickaudi]

Haven't had the 4 hours SOT that I got when I first got my 6P for a while now. Something is keeping the phone from deep sleep. I've wiped the phone and reinstalled the latest PureNexus ROM and radios, etc. - no improvement. I've turned motion sensors off for Google Play Services - no improvement, so turned them back on. Turned off ambient display - no change, so turned back on. I'm running minimal apps - mainly Google stuff, like Drive, etc.

Looks like Google Play Services is using a bunch of sensor data - I've uninstalled all updates - no change.

Below is the GSam data. Let me know what you think.

Perhaps turn off google sync for a while to see if it helps.

It may just be gmail or any other app that just got updated causing the battery drain.

Test it out and let me know

Tried that, no change. Screen uses 12%, kernel and Android system were over 30%.

You may just need to try a new kernel, you see all those kworker processes?

All of those are of different things waking up your phone, but off the log you provided it has to do woth the kernel internal and not any known apps.

Then it maybe the kernel source causing the issue.

Most custom kernels are all based off the same source.

Thought about that as well, so I swapped from PureNexus to CarbonROM to NitrogenOS. Saw similar on all 3 ROMs.
Took my phone in to have battery replaced. We will see how that goes.

My phone (Sony Xperia) using the battery in similar proportion. It is normal, most of the time your display is off, most battery is using Android kernel and Google Services.

I've turned off Google services and GPS. It didn't drop my usage. And my screen on time was still 2 hours.

 

[quickaudi]

So, I got my battery replaced. I've been getting 3-4 hour screen on time range (right now I'm 2.6 hours with 20% battery left), and I've been able to take the battery down to 1%, whereas before it would shut down at 20%.

While the other stuff is still higher than the screen, but I'm better off than I was.

Hi,

What happens when you turn wifi and wireless data off? If the phone goes silent then you can configure Tasker to turn these off when you lock the screen and back on when you unlock it. That way your battery will only be used when you are looking at the phone.

Of course this only works if you are not desperate for your notifications (or, in the case of some of my family: have the screen on all the time).

Regards,
Eric.

Thanks for the input. I've really been much happier with the new battery. Nearly got 4 hours SOT the other day.

I'm going to go out on a limb, since I had those same issues, and blame the age of the battery. I can go all the way to 1% now before it shuts down.

I have noticed that if I turn auto rotate off, then Android OS disappears from the list. When I do want to rotate the screen, I use the app "Rotate".

 

[quickaudi]

Interesting. Are you stock or rooted?
