How to Change Auto Lock on the iPhone 15

In this section, we will walk you through the steps needed to change the auto lock setting on your iPhone 15. This adjustment will help you tailor your phone’s behavior to better suit your needs.

Step 1: Open the Settings app

Find and tap the “Settings” icon on your home screen.

The Settings app is the hub of all your iPhone’s configurations. It looks like a gray gear and tapping it will open up a wealth of options for customizing how your phone works.

Step 2: Tap on “Display & Brightness”

Scroll down a bit in the Settings menu until you see “Display & Brightness,” then tap on it.

This section contains various settings related to your iPhone’s display, including brightness adjustments and some other important features like auto lock.

Step 3: Select “Auto-Lock”

Within the Display & Brightness menu, find and tap on the “Auto-Lock” option.

The Auto-Lock setting controls how long your iPhone will wait before automatically locking the screen when not in use. It’s an important feature for both security and battery conservation.

Step 4: Choose your preferred timing

Pick the duration you want your iPhone to wait before locking, ranging from 30 seconds to 5 minutes, or choose “Never” if you don’t want it to lock automatically.

Selecting a shorter duration can help save battery life and increase security, while a longer duration might offer more convenience when you’re using your phone intermittently.

Step 5: Confirm your selection

Once you’ve picked the timing, simply exit the settings, and your choice will automatically be saved.

There’s no need to hit a save button; your iPhone will remember your new setting right away. Just navigate back to your home screen or any other app, and you’re all set.

After you complete these steps, your iPhone 15 will use the new auto lock timing you have chosen. This will determine how quickly your device locks itself when it is not being used, enhancing both its security and battery life.

Tips for Changing Auto Lock on the iPhone 15

  • Adjust the auto lock setting to 1 minute if you are concerned about security; this will lock your phone quickly when not in use.
  • Choose a longer auto lock duration if you frequently use your phone for reading or following recipes, so it won’t lock while you’re still using it.
  • Avoid setting the auto lock to “Never” unless you have a specific need for it, as it can drain your battery quickly and reduce security.
  • Regularly review and adjust this setting to match your current usage patterns and habits.
  • Remember that shorter auto lock durations not only save battery life but also reduce the risk of unauthorized access if you leave your phone unattended.
