Why Does iPhone 15 Screen Stay On? A Comprehensive Guide to Troubleshooting

I. Power Management Settings

Your iPhone’s power management settings play a crucial role in determining how long your screen stays on. If certain features are enabled or configured incorrectly, it can lead to the screen remaining active unnecessarily.

  • Always On Display (AOD) feature: The Always On Display feature allows you to view essential information (time, date, notifications) even when your iPhone is locked. However, this feature consumes battery power and can contribute to your screen staying on longer than desired. Consider disabling it if you want to extend battery life.
  • Auto-Lock timeout: The Auto-Lock timeout setting determines how long your iPhone’s screen remains active before it automatically turns off. If the timeout is set to a relatively long period (e.g., 5 minutes), the screen may stay on unnecessarily, draining the battery. Adjust the timeout to a shorter period (e.g., 30 seconds or 1 minute) to conserve power.
  • Raise to Wake: The Raise to Wake feature automatically wakes your iPhone’s screen when you lift it. While convenient, it can lead to accidental screen activation, especially if your iPhone is frequently jostled. Disable this feature if you find it unnecessary to have the screen turn on every time you pick up your phone.

II. App or System Issues

In some cases, the issue of your iPhone’s screen staying on may be related to problematic apps or system settings. These issues can disrupt the normal behavior of your device and prevent the screen from turning off as intended.

  • Background apps running: Background apps, even if not actively used, can continue to run on your iPhone, consuming resources and potentially preventing the screen from turning off. Periodically close all open apps to ensure that only the necessary ones are running.
  • Faulty software updates: Occasionally, software updates may contain bugs or glitches that can affect various aspects of your device’s functionality, including screen behavior. If you suspect that a recent update is causing the screen to stay on, consider contacting Apple Support for assistance.
  • Corrupted settings files: Corrupted settings files can disrupt the normal operation of your iPhone, leading to various issues, including the screen remaining on. Resetting all settings to factory defaults can resolve such issues by restoring the settings to their original state.

III. Hardware Problems

While software issues are more common, there’s also the possibility that the reason your iPhone’s screen stays on is due to hardware problems. These issues can affect the functionality of the screen or its associated components.

  • Damaged screen: If your iPhone’s screen has been physically damaged (e.g., cracked, scratched), it can lead to malfunctions, including problems with the screen turning off. In such cases, it’s advisable to seek professional repair to restore the screen’s proper functionality.
  • Faulty battery: A faulty battery can affect the overall performance of your iPhone, including the screen’s behavior. If the battery is not providing sufficient power, the screen may flicker or stay on even when the device is in sleep mode. Consider replacing the battery to resolve this issue.
  • Proximity sensor issues: The proximity sensor, located near the top of the iPhone, detects when the device is close to your face during calls. If the sensor is faulty, it may fail to recognize when you’ve moved the phone away, causing the screen to remain on unnecessarily.

IV. Troubleshooting Steps
