I saw that tipp before, but on twitter I saw that it did not help much on macOS 12. But of course you are right, one should try everything. Therefore I did. And it helped to bring it down to 90 - 115%.
But I saw something else in the logs. Before I limited the scope to warnings and errors. Without the filter I saw that suggestd logged the contacts that are allowed to send me text massages, even when my screentime is "over".
- The numbers got logged in clear. Which I would consider bad practice.
- There where a lot of those massages.
Thus I deactivated screen time. And well... it helped to drive it down to 15 - 20%, which I consider still too high. But AddressBookSourceSync is up to 50 - 70 % 🙈
adding up all internal apple process I'm still over 100 %.
But I guess that the problem will be mixture of Addressbooksync, which gave me a major headache anyways, and Screen Time. Looking into the statistics I noticed that Facebook had a Screen Time of 100% every day. But the thing is... I'm not a frequent user of Facebook. I don't have the app installed on my iPhone and I only use the web version in private mode. Thus I should not be logged in.
