The only reliably persistent thing which keeps running in background is Termux.
I don’t know how, but it just doesn’t die in background. I also use it for downloads with wget. I can lock the phone, and it will keep working until it’s done. Any browser just has a high chance of dying.

Aside from the 3 top right icons (probably) not showing correctly it seems to run. But I never used it, so I don’t know what to test in there.
