Battery Usage meter is crazy or Bluetooth is eating my battery.

[Hobbes2099]

I've noticed that lately (couple of months) my beloved Z4 tablet's battery performance is less than optimal.
I'm about to go through the song and dance of battery optimization, but I wanted to find abusive apps.

Here's what I see; battery is being consumed mostly by the bluetooth connection I keep on nearly 100% of the time I'm using my tablet because of the BK50 keyboard.

Is anyone experiencing something similar or has any recommendation?

thanks,

Im using lineage os and some gladly helped me out with battery im sure tis will work on stock rom no root too. Enable aeroplane mode, disable WiFi when screen is off and disable Bluetooth. Not sure why but I noticed WiFi greatly drains the battery having it off makes it last much longer.

any recommendation?

I would try to upgrade to the latest ROM and hopefully some Bluetooth settings are reset after this.
If this does not help do a factory reset.
You could also try a search on "bluetooth reset" on xda.

I get several days of usage (reading, websurfing in the evenings) out of my tablet where Bluetooth is normally switched of.

On my SONY XZ where Bluetooth is on but only utilized in the car or sometimes with a headset it does not even make it to the list of battery drainers.
