Fix iPhone Always On Display Turning Off Unexpectedly

If your iPhone’s Always-On Display keeps turning off unexpectedly, the fix usually involves checking the Display & Brightness settings, disabling Attention Awareness, or adjusting the Low Power Mode setting. This guide walks through the most common causes and step-by-step solutions to keep your lock screen visible when you want it to be.

What Is Always-On Display on iPhone?

Introduced with the iPhone 14 Pro and available on all Pro models since, Always-On Display (AOD) keeps the lock screen visible at a dimmed brightness. It shows the time, date, widgets, and wallpaper so you can glance at your phone without waking it. The feature relies on the display’s ability to drop its refresh rate to as low as 1Hz, preserving battery while keeping information on screen.

Unlike Android implementations that often show only a black screen with white text, Apple’s version keeps your full wallpaper visible, just dimmed. This makes it more visually appealing but also more noticeable when it suddenly goes black.

Why Does My Always-On Display Keep Turning Off?

There are several reasons your AOD might turn off on its own. The most common is that your iPhone is in Low Power Mode, which disables the feature entirely. Other causes include:

Attention Awareness enabled – the phone checks if you’re looking at it and dims the display when you’re not.
Display Sleep set too short – if your Auto-Lock is set to 30 seconds, the screen may turn off before you expect it.
Face ID or proximity sensor issues – a case or screen protector can interfere.
Software glitches – a bug in iOS can cause the display to shut off randomly.
Overheating – if the phone gets too warm, it may disable AOD to cool down.

How to Fix Always-On Display Turning Off

Follow these steps in order. Most users find the fix in the first two steps.

Turn off Low Power Mode – Go to Settings > Battery and toggle off Low Power Mode. When this is on, AOD is automatically disabled. You can also check Control Center – if the battery icon is yellow, it’s on.
Disable Attention Awareness – Go to Settings > Face ID & Passcode, enter your passcode, and toggle off Attention Awareness Features. This stops the iPhone from checking if you’re looking at it, which is a common reason the display dims or turns off when you glance away.
Check Auto-Lock settings – Go to Settings > Display & Brightness > Auto-Lock and set it to Never. A short Auto-Lock time can override AOD in some situations.
Restart your iPhone – Press and hold the side button and either volume button until the slider appears, then slide to power off. Wait a few seconds, then turn it back on.
Update iOS – Go to Settings > General > Software Update and install any pending updates. Apple frequently fixes display bugs in updates.
Reset all settings – Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This won’t delete your data, but it resets display, Wi-Fi, and other preferences.

How to Adjust Always-On Display Settings

You can customize AOD to show only what you need. Go to Settings > Display & Brightness > Always On Display. From there you can toggle off Show Wallpaper or Show Notifications to reduce battery drain and potentially avoid unexpected shutoffs. Some users find that turning off the wallpaper makes the feature more stable because the phone doesn’t have to render a complex image at low refresh rates.

Also consider enabling Sleep Focus during night hours – this automatically dims the AOD and can prevent it from turning on at all if you prefer complete darkness.

Common Misconception: Always-On Display and Battery Life

Many users assume AOD is a major battery drain, but Apple designed it to use very little power thanks to the LTPO display. In practice, it typically uses less than 1% of battery per hour. However, if your battery health is degraded (below 80%), the phone may disable AOD to preserve power. Check your battery health in Settings > Battery > Battery Health & Charging. If it’s low, consider a battery replacement.

Another misconception is that AOD is the same as the lock screen. It’s not – the lock screen appears when you wake the phone, while AOD is the always-on state. If your AOD turns off but the lock screen still works, it’s not a hardware failure.

What to Do If the Fix Doesn’t Work

If you’ve tried everything and AOD still turns off unexpectedly, there might be a hardware issue. Try these last steps:

Check for a faulty proximity sensor – remove any case or screen protector and test again.
Restore your iPhone – back up to iCloud or a computer, then do a factory reset via Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Set up as new to see if the issue persists.
Contact Apple Support – if the problem continues after a restore, it may be a hardware defect. Apple’s diagnostic tools can identify sensor or display issues.

Frequently Asked Questions

Does Always-On Display turn off when the phone is face down?

Yes, by default, if you place your iPhone face down, the AOD turns off to save battery. This is a feature, not a bug. You can disable this in Settings > Display & Brightness > Always On Display by turning off Show Wallpaper or by using a compatible case that doesn’t trigger the sensor.

Why does my AOD turn off when I’m not looking at it?

This is due to Attention Awareness. The phone uses the TrueDepth camera to detect if your eyes are on the screen. If you look away, it dims the AOD. Turn off Attention Awareness in Face ID settings to keep it always on.

Can I set a schedule for Always-On Display?

There’s no direct schedule, but you can use Focus modes. For example, create a Sleep Focus that automatically turns off AOD during certain hours. Go to Settings > Focus and customize the display options.

Will Always-On Display damage my screen?

No. OLED screens are designed for this use. The pixels that display static elements (like the clock) may experience slight burn-in over years, but Apple uses pixel shifting and other techniques to minimize it. It’s safe to use normally.

Does the Always-On Display work with any wallpaper?

Yes, but some wallpapers (like those with bright colors) may cause the AOD to dim more aggressively to save power. If you notice unexpected dimming, try a darker wallpaper.

Why does AOD turn off during phone calls?

During calls, the proximity sensor turns off the display to prevent accidental touches. This is normal. The AOD will resume after the call ends.
