Plus 1 for a refurb or gently used Dell Latitude series. My daily beater for the last 5 or 6 years has been a pre-2020 Dell Latitude 7390 13". Works really well with the *bian distros I've run on it, decent battery life, OK mic and speakers.
I've had to replace the battery once, and the keyboard once (which I damaged myself by applying a small amount of Coca Cola).
Refurb ThinkPads are also great, but they have a high resale value.
Had some good Chinese takeaway tonight, which was a treat. Ate that while watching my countrymen descend into some kind of froth for dystopic, authoritarian autocracy. That's kind of a bummer.
"Restricted" means the app has been limited by your Android on the amount of data it may transmit/receive as a background app. The app settings assume you're on a meterd or low-volume data plan, and so they don't transmit data except when they're active, or up on your screen.
Their upload/download tallies will still count in your Network accounting. Frankly, your screenshot looks like something I'd expect. Nothing untoward seems to be occurring.
Let those other restricted apps 'run in background" (an app permission) and you'll see a different picture.
