Were you using an exit node? Because that really does hammer the battery, but vanilla TS without a bunch of traffic doesn't seem to do much to mine.

The only always-on TS service on my phone is Immich for photo backup, and I don't take enough photos for that to matter much.

I wasn't, no. I'm not the only one whos hit it either, not sure what the cause is :(

You should compare battery consumption of TS exit node with something like WG app which low

WG gonna punch through NAT for me?

My endpoint is a pretty stable (though technically dynamic) IPv4 on one end, but the other might be a cell phone with CGNAT, some random WiFi, blah blah etc. TS does that. If you don't want to use it, cool. Don't. I'm willing to make the tradeoffs to use TS for now. That could change in the future.

No but hole punching isn't really needed in that scenario. Open a port on the IPv4 side + dyanmic DNS. More than likely that is what tailscale is doing for you. Opening a port on that end w/UPnP. But can't argue with how simple it is with tailscale.

Yeah, I could do that, and it would work for most of the time, but TS does it for even the weird cases when I’m away from home and can’t play with it.

EDIT:good call, though.
