How to Fix Auto Lock Grayed Out on iPhone 11 and 11 Pro

To save battery life and enhance the security of your iPhone, Apple provides an auto-lock feature that locks your iPhone after a certain time limit. So, if you forget to lock your iPhone, it automatically locks itself. This is a handy feature as it protects your iPhone against prying eyes. However, the default auto-lock time limit, which is set to 30 seconds, might become a hassle for some users. Since the introduction of biometric authentication like Touch ID and Face ID, the unlocking process has become simpler. Still, it’s a hassle to unlock your phone every time you want to use it. Thankfully, Apple includes a setting to change auto lock time and even completely disable it. But, some users are reporting that the setting has been grayed out. So, let’s see how we can fix the auto lock grayed issue on iPhone 11 Pro.
