The iPhone 15 features a stunning OLED display designed to stay on when you need it and turn off to save battery when you don’t. Sometimes, you may want to manually turn off your screen to save power, lock your device, or troubleshoot. This guide will walk you through all the ways to make your iPhone 15 screen turn off quickly and efficiently.
1. Use the Side Button to Turn Off the Screen
The simplest way to turn off your iPhone 15 screen is by pressing the Side button (previously known as the power or sleep/wake button):
- Press the Side button once: This immediately turns off the screen and locks the iPhone.
- Your iPhone will stay locked and the screen will remain off until you wake it again by pressing the Side button or tapping the screen.
2. Set Auto-Lock to Turn Off the Screen Automatically
Your iPhone 15 automatically turns off the screen after a period of inactivity to save battery. You can adjust this timing:
- Open Settings.
- Tap Display & Brightness.
- Select Auto-Lock.
- Choose the time interval (from 30 seconds up to 5 minutes, or Never).
- After the selected time without interaction, the screen will turn off automatically.
3. Use AssistiveTouch to Turn Off the Screen
If your Side button is hard to reach or not working, you can turn off the screen using AssistiveTouch:
- Go to Settings > Accessibility > Touch > AssistiveTouch and enable it.
- Tap the AssistiveTouch on-screen button.
- Tap Device.
- Press and hold Lock Screen until the screen turns off.
4. Turn Off Screen Using Siri
You can also ask Siri to lock your iPhone, which turns off the screen:
- Activate Siri by saying “Hey Siri” or pressing the Side button.
- Say “Lock my iPhone”.
- Siri will lock the device and turn off the screen.
5. Use the Power Off Slider to Turn Off the Screen and Device
If you want to turn off your iPhone completely (not just the screen):
- Press and hold the Side button and either Volume button simultaneously until the power off slider appears.
- Drag the slider to turn off the iPhone.
- This turns off the screen and powers down the device.
6. Troubleshooting: Screen Won’t Turn Off?
If your iPhone 15 screen won’t turn off:
- Try a force restart: Quickly press Volume Up, then Volume Down, then hold the Side button until the Apple logo appears.
- Check if any apps or settings are preventing sleep (e.g., navigation apps or video players).
- Reset all settings: Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings (this won’t delete your data).
