How to change auto lock on iPhone?


After 30 seconds of inactivity, the iPhone screen will automatically lock when it’s put into Auto-Lock mode when you first get it. Being forced to hand your phone back to someone to unlock can be extremely annoying, especially if you’re letting someone else use it.

Your iPhone will stay on if it’s busy being used. Some functions, such as running a timer, don’t count as activity on the iPhone. The screen will still turn black, so it’s impossible to see how much time there is left without changing your screen settings.

This is programmed into your iPhone for multiple reasons. This feature is not to everyone’s taste, so if you don’t like it or think that your iPhone locks too early, you can fiddle with Auto-Lock’s settings to suit your needs. You will learn everything you need to know about how to change auto lock on iPhone in this article.

You will understand why Auto-Lock exists, how to personalize it, and how to resolve some issues associated with it after reading this article.

What Is Auto-Lock on the iPhone?

Sleep mode is another term for auto-lock. After a set amount of time, Auto-lock activates a timeout for the screen, unless it is disabled. In a similar way to your computer going to sleep after a set period, the iPhone dims the screen in order to conserve battery power. Setting your iPhone’s screen to sleep earlier can help you save battery life if your iPhone runs out of power too quickly. To change the Auto-Lock setting, click on the Lock icon in the Settings menu. Auto-Lock can be completely disabled, however. This tip will allow you to change your iPhone’s Auto-Lock time if it keeps shutting off.

Why does the iPhone have Auto-Lock?

Knowing that Auto-Lock is a feature that locks your iPhone, why is this feature present on an iPhone? There are several reasons for this.

A security measure has been implemented because if your iPhone is unlocked and if you are not around it, there is a possibility that someone could snoop or do something malicious. Therefore, even when your iPhone Auto-Locks itself, it will remain safe while you are away from it.

In addition to preserving battery life, your iPhone automatically locks itself. The screen will go to sleep when your iPhone Auto-Locks and background tasks will be suspended, thus saving battery life. As a result, if you were using your iPhone and fell asleep, it would automatically shut down to conserve battery life after some time.

On the other hand, this can also be annoying in some cases, since your iPhone may go into Auto-Lock even when you’re not looking for it. During such times, you can change the Auto-Lock settings to suit your preferences. The following instructions will explain how to change the Auto-Lock setting on your iPhone.

How to change Auto Lock on iPhone?

With a few clicks, you can alter the Auto-Lock setting that turns off your screen.

  • Click on Settings.
  • Select “Display & Brightness.”

  • Select “Auto-Lock.”

  • Set how long you want your iPhone screen to remain on after you last touched it. If you don’t want to wait 30 seconds, you can wait anywhere from one to five minutes, or never. Unless you turn your screen off manually by using the button on the side of your phone, your screen will remain unlocked and awake all the time.

There might be a reason why the “Never” option is not displayed, such as if your iPhone is managed by an organization, school, or another administrator. It is in these situations that you will need to contact the administrator for further information.

When you are finished with setting your iPhone screen to always be on for a short period of time, remember to change it back to Auto-Lock. It is a good idea to leave your phone on the Never setting in order to quickly drain its battery and allow anyone to access your apps.

How do I fix the iPhone that keeps going to lock screen (bug)?

A user’s screen goes black when they’re using an app, displays a spinning wheel at the center, and then reverts to the Lock screen. Why are these iPhones so difficult to unlock? The original post of this solution on Reddit notes that many users have had immediate success deleting the app Headspace and restarting their phones. However, if you do not have the Headspace app and are still experiencing this issue, or if you would rather not delete that app, there is another method you can use. You can resolve the “iPhone keeps going to the lock screen” issue by following these steps. 

You must disable all Notifications first. Here are the steps:

  • Go to the Settings app.
  • Choose Notifications.
  • Each app can be accessed by tapping the arrow.
  • For every app, turn off Allow Notifications. 

Your next step is to upgrade to the latest iOS or iPadOS. As soon as your device has been updated fully and downloaded, you can go through and turn on notifications for the apps you wish to receive notifications from; although, I recommend not turning on notifications for Headspace for the moment. 

For further assistance, contact Apple Support. You may also want to check the epic Reddit forum to see if anyone else has come up with a solution that might work for you.
