How to Adjust Auto-Lock Screen Timeout Period on iPhone

Before we get into the nitty-gritty, adjusting the auto-lock timing is about finding the right balance between convenience and security. Let’s see how you can customize this setting to suit your needs.

Step 1: Open Settings

Start by tapping the Settings icon on your home screen.

The Settings app is your go-to place for all things iPhone customization. It’s where you can tweak your device to work just the way you like it.

Step 2: Select Display & Brightness

Scroll down and tap on Display & Brightness.

This menu holds all the options related to your iPhone’s screen, from brightness levels to text size and now, the Auto-Lock feature.

Step 3: Tap Auto-Lock

Once in the Display & Brightness menu, find and tap on the Auto-Lock option.

Auto-Lock is the feature that determines how long your iPhone stays awake before the screen goes to sleep.

Step 4: Choose the desired time

You’ll see several time options ranging from 30 seconds to 5 minutes, or even Never. Tap on the time that suits your needs.

Choosing ‘Never’ will keep your iPhone awake until you manually lock it, while selecting a shorter time, like 30 seconds, will lock it quickly when not in use.


Saves Battery LifeBy reducing the time your screen stays on when not in use, you save significant battery power.
Increases SecurityA shorter auto-lock time means your phone locks faster when idle, reducing the chance of unauthorized access.
Prevents Burn-InWith OLED screens, having static images for too long can cause burn-in. Auto-lock helps by turning off the screen.


InconvenienceConstantly unlocking your phone can be annoying, especially if you set the auto-lock period too short.
May Affect Certain AppsSome apps that require the screen to stay on may not function properly with a short auto-lock time.
Risk of Data LossIf your phone locks while you’re in the middle of something, you could potentially lose unsaved data.

Additional Information

When adjusting the Auto-Lock settings on your iPhone running iOS 17, it’s essential to consider your personal preferences and the way you use your device. For instance, if you’re someone who reads a lot on your phone, you might want to set a longer Auto-Lock period to avoid frequent screen dimming. Conversely, if you’re concerned about privacy and security, a shorter Auto-Lock time can give you peace of mind.

Remember that adjusting this setting can also impact battery life. A shorter Auto-Lock time can help conserve battery, as the screen is one of the biggest power drains on your iPhone. Additionally, if you’re in a situation where you need your screen to stay on for an extended period, like when following a recipe or using your phone as a navigation aid, you can temporarily select ‘Never’ for the Auto-Lock period. Just don’t forget to change it back afterward to avoid unnecessary battery drain.
