"Enter your passcode to trust this computer and start a backup." Every time iPhone is on charge.

After the upgrade to iOS 16.1 from iOS 15.7, with no other changes to my paired iMac, my iPhones now both routinely ask me to type in my passcode to trust this computer and start a backup. This happens whenever the device is put on charge, even if only to AC power, and the sync and backup happens over Wi-Fi. Why, and how do I put a stop to it so it goes back to the iOS 15 and expected behaviour of doing the sync and backup over Wi-Fi automatically and immediately when the device is put on charge?


I've looked around and tried various solutions, all to nothing. I reset privacy and network settings, repaired over USB, restarted everything, etc. It's still happening.

iPhone 13 Pro Max, iOS 16
