What is the impact of “raise to wake” and “WiFi calling” on battery life? (alien.top)

I have noticed that I see many different opinions in this. Raise to wake goes from “it’s a constant drain” to “negilble”. And for WiFi calling I have literally seen both that it has a negative (it’s constantly maintaining WiFi signal, especially on 5Ghz WiFi that can be an issue) or a positive impact (it doesn’t have to connect to a transmission mast / post further away) on battery life.

So I was wondering how do you feel about the above? I always had both turned off because I personally felt that was better for battery life. But I have recently turned on raise to wake again because the functionality just makes things nicer to use!

Don’t think raise to wake matters much unless you also turn-off the Health App (step counter) - either one turned on means the accelerometer runs 24/7 IMHO. I use a shortcut to toggle between wifi-calling/cellular when I’m home/out, so only 1 antenna runs at a time. GPS is huge as Apple uses as many phones as possible as crowdsource beacons. FWIW, I’m a battery/efficiency hobbyist that gets Apple’s ‘up to’ SOT spec for year.
