Step by Step Tutorial: Fixing Your iPhone 15 Screen Issue

Before we dive into the steps, it’s essential to understand that this tutorial aims to troubleshoot and fix the problem of your iPhone 15 screen not turning off. This could be due to a variety of reasons, including settings that need adjustment or a minor software glitch.

Step 1: Check Auto-Lock Settings

First, ensure that your iPhone’s Auto-Lock feature is set correctly.

Auto-Lock is a feature that automatically turns off your iPhone screen after a certain period of inactivity. If this setting is set to ‘Never,’ your screen won’t turn off on its own. To check this, go to Settings > Display & Brightness > Auto-Lock and choose a suitable time frame.

Step 2: Restart Your iPhone

Sometimes all your phone needs is a quick restart.

Restarting your iPhone can resolve minor software glitches that may be causing the screen to stay on. To do this, press and hold the side button and either volume button until the power off slider appears. Drag the slider, then wait for your device to turn off. Turn it back on by pressing and holding the side button until you see the Apple logo.

Step 3: Update iOS

An outdated iOS can cause various issues, including screen problems.

Make sure your iPhone 15 is running on the latest iOS version. To update, go to Settings > General > Software Update and download and install any available updates.

Step 4: Reset All Settings

If all else fails, resetting all settings might be the key.

This step should be your last resort as it will reset all your personalized settings to their defaults. To do this, navigate to Settings > General > Reset and tap on Reset All Settings.

Step 5: Seek Professional Help

If you’ve tried everything and the screen still won’t turn off, it might be time to consult the experts.

If none of the above steps work, your iPhone might have a hardware issue. In this case, it’s best to contact Apple Support or visit an Apple Store for professional help.

Once you’ve completed these steps, your iPhone 15 screen should turn off as expected when not in use. This not only saves battery life but also prevents unintended touches and potential privacy concerns.

Tips: Ensuring Your iPhone 15 Screen Turns Off When Needed

  • Regularly check for and install any available iOS updates
  • Avoid setting Auto-Lock to ‘Never’ unless necessary for a specific task
  • Restart your iPhone periodically to clear minor software glitches
  • Consider enabling Raise to Wake feature for easier screen management
  • Use AssistiveTouch if the physical buttons on your iPhone are unresponsive
