Hey guys. Since the April update I've noticed I'm getting a fair bit of Bluetooth Battery drain on my Ultra. Only thing I have connected all the time is my Huawei GT2 Pro watch, but this has always been the case and never had the issue.

Just a small snap shot from this morning.
Never used to see any Bluetooth use here really. Have rebooted both devices but seems to be getting worse.

Any ideas ?

I don't think Karma Firewall's logging feature works in Android 10 or 11.
That would allow you to see what is accessing the internet and how often. Might give you a clue to what app is responsible.

It may be an app connected with the watch that's gone wild. Google Play Services is a known troublemaker and battery hog.

Why is app usage so high?
It's not broke down by app. Wonderful.
More Android 10/11 security?🤣

Try disabling Google Play Services... just a hunch.
If that doesn't work...
Go to Developer options>running processes/cache processes after a reboot and see if you can spot it.

Is that high ? Went through ADB to break down the app usage ...

That is a mess. Ditch the trash social apps especially FB and instashit. Health is doing what? Is DeX just hanging out too?
All that message stuff?
G Board?

Which of these has bluetooth permissions?
Time to take out the trash... if you can bare to part with it. It all adds up.
The Adroid system looks high too.
Disable all power management after you take out the trash. Power management can cause erratic behavior and battery drain.

This what my 10+ battery profile looks like. I was using bt for a couple hours but it's bare bones.
The bells and whistles are power sucking and annoying.

Health is the app used to connect to the watch. G BOARD is the Google keyboard ? Use that all the time (same as IG and FB unfortunately)

Have you tried turning off nearby device scanning (under connections) and Bluetooth scanning (under improve accuracy in location)?
Also are you able to see if anything is draining your watch faster than it was before?

Yeah they are off already. The watch itself seems fine though

That should be ok then.
Google apks are notorious troublemakers though. Even Gmail I keep on a short leash.

Maybe the data in Health got corrupted, try clearing data or reloading it.
Don't forget all the Google apps and their many dependencies. One might be polling constantly and going unanswered*.
Tracking something like that down on a unrooted Android 10 or 11 platform is a bloody nightmare.

*I simply disabled Google Play Services expect when I need it because this.

If you disconnect the watch does the drain stop? Does the drain continue if you connect a different device? Might be easier to try resetting the watch before the phone?

Will disconnect the watch tomorrow when I wake and see.

It's been ok today. Only at 2% for the day

(Google Play services however showing as my second most used app )

You can disable GplayS in settings to see what happens. Mine is disabled right now.

You can also download Karma Firewall then firewall block GplayS, Google backup Transport and Android Services if those latter two aren't used by you. See if this helps.

    That is the easy way...
    Do a Google search if you don't know how for that make/model.
    Network reset is generally found in setting under connectivity at least on Samsung's.

    Cache clear seems to have fixed it for now ....cheers !!

    When I disabled GPS though , so many things didn't work - Google Pay, Google Keyboard etc
    Google apps will leave you high and dry eventually.
    Zero trust in Google... they earned it.
    Gmail is the only one I use daily... and that too may change.

    Remember this, with Google you are the product not a customer. Google is a parasite.
