I ran into that after the iOS 17 update. A reboot fixed the problem.
Reboot seems to be helping somewhat.
Tailscale has been eating my battery, but yeah my 13 mini has been chewing battery more lately.
First its more helpfull to show statistics for last 10 days so we can see your usual battery life. Second you have 3h off screen time, so it means something that is in the background is eating your battery…
I think it’s Voyager.
Haha funy joke…
No, really…
If you are serios its easy to check that. You have procent that voyager drained and also number of howers that you used the app. Didnt notice it drained any battery on my phone so i daubt it drained large amount on yours…
Apple has a battery health screen you can go check. What is the percentage it shows on your battery health?
86%
