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.

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

  1. Here, tap on “Low Power Mode” and disable it.

The above steps will solve the problem for everyone. However, some users have reported that their auto-lock feature is disabled or grayed out even when their iPhone is not on low power mode. If that’s the case with you, you will have to take the route of tried and tested methods that solve eccentric issues on iOS devices. Before trying any of these steps remember to take a back-up of your data so you don’t lose it.

The first thing you should try is force restarting your iPhone. Most of the time, a good force restart can solve many iOS problems that you are facing. The steps to force restart are different for an iPhone with Home Button and one without it. So follow the steps below.

On iPhone with Home Button: Hold down the Home and sleep/wake buttons at once for about 10 seconds to force restart your device.

If the above steps didn’t work you, try resetting your iPhone’s settings. To do this, go to Settings -> General -> Reset and choose the “Reset All Settings” option. Remember that this step will change all the settings to their default state. So, any changes you have made to your settings app will be lost.

Sometimes an error may result from a faulty iOS update. So always make sure to update your iOS device. To see if there’s a pending update or not go to Settings -> General -> Software Update and update your device if it’s pending.
