iOS 12 boasts multiple security features including the highly effective USB Restricted Mode. So, what does this new setting do? Once activated, it prevents USB accessories from connecting to iPhone if it’s been more than one hour since the device was last unlocked. They will require your authentication to connect to the iOS device. However, you can choose to toggle ON/OFF USB accessories on your iOS 12 based on your need.

By default, USB accessories are restricted to have the access of the iPhone if it hasn’t been unlocked for more than an hour. Though it’s a great security feature, you might want to disable the USB Restricted Mode, if you regularly sync your device with iTunes.

Your take
