S21 headphone issues on mobile data

[Churf]

While I wait with baited breath for the freebie Buds with my S21, I wanted to try using the phone with my bose earbuds. I bought the USB C to 3.5mm jack and at home, all was well.

Took the dog for a walk and I noticed, when phone was on mobile data, the media (BBC sounds or YouTube Music) worked for about 10 seconds and then disconnected. I reinserted the USB jack again and again, and it always disconnected after about 10 seconds, so I have up. I know my data is fine as Strava was working.

When I came come and back on WiFi, the headphones was fine. As soon as I disconnected WiFi and used mobile data in the house, the headphones stopped again after 10 seconds, but the music was still playing, so again, I know the data was OK.

So my question is, why would my USB C to 3.5mm jack, 'turn off' when playing music via mobile data and not via home WiFi. I'm confused!

could it be the app you are using? and not the connector

Mine is doing the same, have you managed to solve the problem?

[Churf]

No is the simple answer. I didn't want to buy another connector but that may be the answer. Mine was off ebay and not Samsung. Anyway I got the free Buds Live today so I'll be using them

I found the answer. The apps I use were going go sleep when not I use ( so when the screen was turned off onwalks).
Go to
settings
battery & device care
battery
background usage limits
never sleeping apps. Find the apps you want to remain alive, like Spotify or YouTube Music

that seems to have fixed it
