Wireguard is amazing.

I have an "always on" VPN routing back home. Anything destined for my home network gets routed that way, and there's literally zero battery drain.

I'm not paranoid enough to route everything through VPN though.

For me it's not paranoia.. more like: I have a ton of unused GBit/s left.. so routing a few kBit... MBit/s of mobile data doesn't hurt.
