Part 1. Why Does My iPhone Keep Going to Lock Screen?

Many iPhone users have encountered a weird issue that the iPhone turns to a black screen and jumps to the lock screen automatically. This could be very frustrating while using it. Here is a list of possible reasons that lead to the iPhone going to the lock screen:

iPhone Settings:

One of the main factors is your iPhone settings. Settings like Auto-Lock, Low Power Mode, and Back Tap will trigger the iPhone screen to keep locking.

System Glitches:

Sometimes, minor system glitches or software bugs can also make the display go black and return to the lock screen randomly.

Hardware Issue:

A hardware problem, such as a faulty power button or internal component, may trigger the device to lock as if you're pressing the button yourself.

Part 2. How to Keep iPhone from Going to Lock Screen

Now that you know why your iPhone keeps going to the lock screen, we'll walk you through a series of step-by-step methods to help you troubleshoot the issue. Whether it's a simple display setting or a software conflict, you'll find a solution.

Method 1. Adjust Auto Lock Timer

If your iPhone keeps going to the lock screen regularly, the most likely culprit is the Auto Lock setting. You can adjust the Auto Lock timer to avoid the iPhone getting locked automatically.

Step 1. Head for iPhone Settings > Display & Brightness.

Step 2. Find Auto-Lock and set a longer timer.

Method 2. Disable Back Tap to Lock Screen

Once you have set a shortcut to lock your iPhone, this could be one culprit. Your iPhone may go to the lock screen if you unconsciously tap the back of your phone. Check the Back Tap settings to stop the iPhone from going to the lock screen.

Step 1. Navigate to iPhone Settings > Accessibility.

Step 2. Find Touch > Back Tap. Check and adjust if you have set the back tap to Lock Screen.

Method 3. Turn Off Low Power Mode

When Low Power Mode is enabled, the Auto-Lock timer is set to 20 seconds by default to help conserve battery life. If you want the screen to stay on longer and avoid the iPhone, you can turn off Low Power Mode.

Step 1. Open iPhone Settings and tap Battery.

Step 2. Find Low Power Mode and turn it off.

Method 4. Restart Your iPhone

Minor glitches will also cause the iPhone to go to the lock screen unexpectedly. A simple restart can clear temporary system issues and reload essential services, giving your iPhone a fresh start.

iPhone X and later:

Step 1. Hold down the power button together with the volume up button.

Step 2. Drag the power off slider to the right to shut down your iPhone.

Step 3. Hold down the power button until the Apple logo appears.

Medols before iPhone X:

Step 1. Keep the power button and the home button pressed until the screen changes.

Step 2. Drag the shut off slider to the end to shut down your iPhone.

Step 3. Hold down the power button until the Apple logo is displayed.

Method 5. Update the Software System

Apple regularly releases iOS updates that fix bugs, improve performance, and address unexpected behaviors, such as the iPhone randomly locking. If you're running an older version of iOS, a known issue could be causing the lock-screen problem you're experiencing.

Step 1. Access your iPhone's Settings and tap General.

Step 2. Tap Software Update and check if there is a newer system version to be downloaded and installed.

Step 3. Tap Download Now or Install Now to update the software system.

Method 6. Reset All Settings

Instead of trying to track down one specific setting, you can reset all settings on your device to return system options to their defaults without deleting your personal data.

Step 1. Go to iPhone Settings > General.

Step 2. Scroll down to the bottom and tap Transfer or Reset iPhone.

Step 3. Tap Reset and choose Reset All Settings. Enter your iPhone passcode to confirm the operation.
