To me, this sounds like a feature.

Basically I'd like the phone to cut off all mobile data, wifi, gps, and other radio and kill all applications when the screen is locked.

OnePlus has some background activity limits and you can turn on the aggressive Doze (or whatever it's called these days) but if my phone is locked I would really, really like to just receive calls and sms and have the system enforce that, and switch off all the unrelated hardware to extend standby time.

I used to do this when I had a rooted phone. I kept the radio active so that I could receive calls and texts but data, GPS and wifi were all off.

It saved battery if I wasn't doing much with my phone. If I was constantly unlocking to check where I was on a map then it ate up more battery and it was incredibly frustrating as it takes a while to get a GPS lock when you don't have Wifi to assist in a city, until Wifi come back on which also takes a while. Friends that only communicate with messenger and Whatsapp had trouble getting through. Loads of apps that had been trying to communicate also woke up once there was a connection using up more CPU cycles, slowing everything down some more.

IMHO, its not worth it. Just use the background apps controller in Android 8.1. Whitelist the things that you do want notifications from and everything else can wait for you to open the app.

You can do this on the iPhone by completely disabling “background refresh”.

It will still poll for notifications - but nothing else.
