[RESOLVED] Kubuntu 24.04 Bluetooth keeps disconnecting

[TheYikes2]

As the title tells, I'm having issues with my bluetooth headphones on kubuntu 24.04. up to recently it was working fine but in the last week or 2 it's inclined to disconnect randomly. The first thing i noticed was while i was playing youtube videos it would make a "Beep" then it would play the song and then it would "Beep" again and disconnect. Has anyone else had this issue?

Obvious question, but are the headphones fully charged?

[TheYikes2]

100% charged. That was the first thing i thought of Snowhog. I like the way you think, keep it simple.......

So then my next question: Does this occur when you aren't watching a YouTube video; just listening to music for example?

I can add my information, all bluetooth devices (mouse and headphones) were working correctly until last week or so.. I can't connect them anymore. restart of service or laptop (Dell Inspiron 15 3530 didn't help.
Pairing again doesn't help

Hey guys. I'm back with an update. SnowDog you were pretty much correct on your assumption about the battery. I was charging it but it wouldn't hold a charge. It was going from 100% to 25% in minutes. Thasnk for you help. On the upside i have a nice new set of headphones to play with!

For me, it was a matter of applying updates... in linux-image-6.8.0-47-generic, bluetooth was not working at all,
after update to linux-image-6.8.0-48-generic, everything works find and laptop is able to find bluetooth devices
