Ubuntu 20.04 – Fix Bluetooth Not Working Often

I'm using powerbeats 3 earphones via bluetooth with my desktop and every 2 days after a boot, I find myself debugging why my earphones don't seem to connect anymore.

I've used the following questions and its answers and used every time I can:

• Bluetooth Problem Ubuntu 18.04 LTS
• Bluetooth not working on Ubuntu 16.04 LTS

Some of the answers work sometimes, and sometimes a combination of them and rebooting my system seem to magically help.

Symptoms of my earphones not connecting through bluetooth anymore:

• Using the GUI, while clicking on the connect on/off button to turn it on, it inmediatelly turns itself off.
• Using bluetoothctl, removing the device, trusting the device again and trying to pair just goes on until it fails due to my device turning off being so long trying to pair.

Might be related to some of these packages:

• bluez 5.53
• libbluetooth3 5.53

I'd like help in debugging this problem, I guess I'm tired of rebooting a few times every few days just to get my earphones working.

Edit: I'm using the tp link ub 400 bluetooth adapter.

"lsusb" result:

Edit 2: To clarify compared to this other question:

"hciconfig" result:

hci0:   Type: Primary  Bus: USB

As you can see, my device shows running compared to the other question in which it shows is DOWN.
