How To Change iPhone Screen Lock Time and Save Your Battery


Mar 29, 2024 • Filed to: Remove Screen Lock • Proven solutions

You might have noticed that your iPhone's screen will turn off and lock itself after you haven't used it for a while. By default, this happens after 30 seconds of inactivity.

But if you are here, you are probably wondering how to change iPhone screen lock time to make the screen stay on for longer. When you're using Maps for directions or reading a long article, for example, you’ll need to adjust the screen lock time to suit your needs.

Below, we will show you how to change lock screen time on iPhone, along with other information you’ll need to know.

Part 1. What Is Screen Time/Screen Time Out on iPhone or iPad?

When your iPhone screen locks itself after a period of inactivity, it will require either your passcode, fingerprint, or face to unlock it again. The screen time or screen time out on an iPhone or iPad is a setting that determines how long the device's screen stays on before it automatically locks itself.

This iPhone screen lock time actually serves multiple purposes. First, it helps maintain your device’s privacy and security by ensuring no one can access it without your permission. Moreover, the automatic screen lock functionality can prolong your iPhone’s battery health by minimizing unnecessary power consumption when the device is not in use.

Part 2. How Does Screen Timeout Affect Battery Life?

In case you are not aware, learning how to set screen timeout on iPhone and adjust it properly is a widely recommended practice to make your iPhone's battery last longer. When your screen stays on, it uses up battery power. So, if you wait a long time for it to lock, you will drain more battery.

On the other hand, if you set up the necessary iPhone screen timeout, you will get to:

  • Prevents unnecessary power drain

If you forget to manually lock your device when you're not using it, the screen may remain on unintentionally and drain battery power. With a shorter screen timeout, the device automatically locks itself after a specified period of inactivity and prevents this kind of power drain.

  • Optimizes standby time

Even when you're not actively using your device, the screen timeout setting influences how quickly the device enters standby mode. When the screen turns off promptly after a period of inactivity, the device conserves power by minimizing background processes and reducing power consumption.

That’s why you need to learn how to change screen lock time on an iPhone and select an appropriate screen timeout duration that balances battery conservation with usability. Opting for a timeout that is too short may also lead to frequent screen lockouts, which can be inconvenient if you're frequently using your device.

Part 3. How To Change Screen Lock Time on iPhone?

Moving on to the next question: how do I change the auto lock on iPhone? You can follow the following step-by-step guide to the auto lock settings on your iPhone. This guide works for all iPhones running the latest versions of iOS.

How to change auto lock in iPhone:

Step 1: Go to iPhone Settings > Display & Brightness > Auto lock.

Step 2: Choose the duration of inactivity before your iPhone screen locks. The options range from 30 Seconds, one to five minutes to Never. If you select Never, your screen will remain unlocked indefinitely unless manually turned off using the Side button.

But remember, if you choose “Never” in the iPhone auto lock setting, make sure to switch back to auto lock when you're done using it. Leaving it on Never can quickly drain your battery and potentially expose your iPhone to unauthorized access if someone else picks up your phone.

Another option is to set it to the longest time (five minutes) before it locks. This way, you won't have to unlock your phone as often, and it'll still save battery power.

If the problem persists, you may need to reset your device settings or contact Apple Support for further assistance.
Currently, Apple doesn't offer the option to set a custom screen lock time on iPhone. However, you can choose from predefined time intervals such as 30 seconds, 1 minute, 2 minutes, 3 minutes, 4 minutes, or 5 minutes.
Changing the screen lock time usually does not directly affect the security of your iPhone. However, shorter screen lock times provide quicker protection against unauthorized access when your device is left unattended.
