Slow Charging of iPhone via USB A port of Mac Mini M1 after iOS16 update

Ever since i updated my phone xr to iOS16, my Mac mini M1 isnt able to charge it at usual speed. It’s taking 10 minutes to increase by 1%. Unprecedentedly slow.


although when tested with Windows Laptop or the original iPad Charger 12W, is charging at much faster rate.


any reason? Any fix?

Mac mini, macOS 12.6

Yes. I did select the 'Trust' option. And to be sure that I did that correct or not, I had also reset my privacy and netowkr settings as well and 'Trusted'ed the computer once again. But still the same.


One thing I noticed was when I connected my phone to the computer for the first time after iOS16 update, my Mac Mini M1 showed an alert saying some extra Mac Updates are required before this phone works with the Mac Mini. I downloaded those as well and restarted my PC as well. Not sure if some issue in that update as well.

If a hard restart doesn’t fix, a full erase/reset might. Sounds like a lot of trouble but really isn’t and it does yield results.


If you go the route, and if restore from iCloud backup doesn’t fix, repeat without iCloud restore, manually install your apps instead (save screenshots to help you with that). The other option is to wait out for the next release. Good luck!
