BT mouse disconnects after a few minutes

I have a bluetooth mouse that works great when connected to AC, but when on battery the BT controller seems to fail or turn off and the mouse stops responding.

Here’s the relevant dmesg output:

Have you already checked those?

The problem is not the BT adapter itself or the mouse, it seems to be something related to power saving. It’s like the BT adapter disconnects itself after a few minutes.

Stopping or restarting the BT service does nothing.

Check TLP settings for the port where the dongle is connected and disable power saving. You can make use of tlpui

I’ll try that, thanks!

Seems like your suggestions fixed my issue, no more BT mouse disconnect when on battery.
