It's amazing how different my phone feels since I've set up Wireguard to a server I have set up a few milliseconds away from me and put a pihole at the end of it, too. Blocking the (web) trackers at their source, coupled with less "wake up the radio to make this network call" is really quite nice, and the in-app advert spaces don't load except for a handful of folks doing (reasonable) native advertising.
Wouldn't you still have to wake up the radio to perform the (pi-holed) DNS lookup, though? Just curious because I would love to use a similar kind of system, but I am concerned about battery life.
I've been doing this for a few months now and the impact on battery life is noticeable but acceptable to me. iOS reports that WireGuard was responsible for 8% of my battery use today.
