Yes, but not through the default settings. You will need a configuration profile (see Method 5), where you can set rules for networks with specific names (for example, Free or Public). Some routers also allow you to configure "client isolation," which prevents devices from automatically connecting.

Why did auto-connect re-enable after updating iOS?

Apple sometimes resets user network settings after major updates (for example, when upgrading from iOS 16 on iOS 17). To avoid this, make a backup before updating iTunes and save the list of networks in a notepad. After the update, check the settings manually.

Will iPhone connect to Wi-Fi if mobile data is turned off?

• Set up Sleep mode V Health → Sleepto restrict device activity.
• Use Shortcuts (Shortcuts) to automatically turn off Wi-Fi on a schedule.
• Install a router with this feature Parent Control and block access iPhone during the night hours.

Does disabling auto-connect affect AirDrop and Handoff?

Partially. AirDrop And Handoff to transfer files between devices Apple Use a combination of Wi-Fi and Bluetooth.
