How to fix grayed out auto-lock on iPhone 11 and 11 Pro

To save battery and increase 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 will lock automatically. This is a useful feature as it protects your iPhone from prying eyes. However, the default auto-block timeout, set to 30 seconds, can become a nuisance 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. Fortunately, Apple includes a setting to change the auto-lock time and even disable it completely. But some users are reporting that the setting has been grayed out. So, let’s see how we can fix the grayed out auto-lock issue on iPhone 11 Pro.

The steps to resolve this issue are the same for all iPhones. So if you are using the latest iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max or older iPhones like iPhone X, iPhone 8 and so on, these steps will work for you. Also, while we are using an iPhone running iOS 13, the steps are the same for older versions of iOS, including iOS 12.

Talking about why this issue occurs, iOS disables the auto-lock feature when you are using an iPhone in low power mode. This is done to preserve your iPhone’s battery life.

With that out of the way, let’s get to the steps.
