The ‘Auto-Lock’ setting controls how long your iPhone will wait before locking the screen.

Step 4: Select Time Interval

Choose the time interval you prefer for your iPhone’s auto-lock feature.

The available intervals typically range from 30 seconds to 5 minutes. The setting you choose depends on your personal preference and how you use your device.

Additional Information

When you’re adjusting the auto-lock screen timeout period on your iPhone, it’s crucial to strike a balance between convenience and practicality. If you’re someone who frequently uses their phone for reading or other static activities, you might prefer a longer timeout period so you’re not constantly tapping the screen to keep it active. On the other hand, if you’re all about preserving battery and keeping your data secure, a shorter timeout will be your best friend.

Remember that your iPhone’s auto-lock feature works hand-in-hand with your passcode and biometric security settings. This means that even if your screen locks quickly, you can still gain speedy access to your device using Face ID or Touch ID. It’s also worth noting that certain apps can override the auto-lock setting. For example, if you’re using Maps for navigation, your screen won’t lock as long as the app is active. Keep this in mind as you experiment with different timeout periods to find the perfect fit for your iOS 17 device.


  1. Open the Settings app on your iPhone.
  2. Tap on ‘Display & Brightness’.
  3. Select ‘Auto-Lock’.
  4. Choose your desired time interval.
