How to use “USB Restricted Mode” on your iPhone
Initially, Apple added “USB Restricted Mode” feature in iOS version 11.4.1 that was providing one hour grace period. During that one hour, you may connect your iPhone multiple times with any USB device. After every USB connection, the timer would be reset on your phone. However, this feature was providing data security at some extent but then also there were chances of hacking. Now, in iOS version 12, apple removed this one hour grace period and whenever you will connect your iPhone with any USB accessories, you will always need to unlock your Phone with Touch ID or Face ID.
After updating your iPhone to iOS version 12, USB Restricted Mode will get enabled by default and prevent people from getting access to your iPhone without permission. If your iPhone is locked and you connect a device, you will always be asked to unlock it. If USB Restricted Mode is activated, your iPhone is always protected.
Moreover, it is not recommended to disable USB Restricted Mode but if you really feel annoyed from unlocking device again and again, you may disable this feature by following the below given steps:
- In order to disable USB Restricted Mode, go to Settings>Touch ID & Passcode (or Face ID & Passcode) and enter your PIN to continue.
- In the “Allow Access When Locked” section, enable the “USB Accessories” option. By enabling this option, devices can connect to your iPhone even if they are locked.
This is how you may easily disable USB Restricted Mode but it is always better to keep enabled to protect your iPhone data from unauthorized access.
