Apple Always-On Display: What It Is, How It Works and What to Expect

Apple’s Always-On Display has become one of the most talked-about features in recent iPhone and Apple Watch models. If you’ve been wondering, what exactly is Apple’s Always-On Display and how does it work?—you’re in the right place.

This guide covers how Always-On Display works across devices, what models support it, how to customize it, and everything else you should know before you start using or buying a device with this feature.

What Is Apple’s Always-On Display?

Always-On Display (AOD) is a feature that keeps part of your screen visible even when the device is locked. Unlike older displays that turn off entirely when inactive, Apple’s AOD shows minimal but useful information—like time, date, widgets, or background dimmed visuals—at all times.

Introduced first on the Apple Watch Series 5 and later on iPhone 14 Pro and iPhone 14 Pro Max, this feature has quickly become a staple in Apple’s premium devices.

How Always-On Display Works

Apple’s AOD relies on LTPO (Low-Temperature Polycrystalline Oxide) display technology, which allows the screen to reduce its refresh rate to as low as 1Hz when idle. This saves battery life while keeping the screen minimally active.

You’ll still see:

• Time and date
  
• Lock Screen widgets (like Weather or Activity rings)
  
• Notifications (if enabled)
  
• Your wallpaper in a dimmed tone
  

The screen intelligently adjusts brightness based on ambient lighting and user activity.

Devices That Support Apple’s Always-On Display

Not all Apple devices support this feature. It’s currently limited to higher-end models that use LTPO display panels.

How to Enable or Disable Always-On Display

If you’d prefer to keep your screen fully off when not in use (for privacy or battery reasons), you can toggle this feature on or off.

On iPhone:

• Open the Settings app
  
• Tap Display & Brightness
  
• Tap Always On Display
  
• Toggle it on or off
  

You can also customize:

• Show Wallpaper: Hide or display the Lock Screen wallpaper
  
• Show Notifications: Choose whether or not alerts show when the display is dimmed
  

On Apple Watch:

• Open the Settings app on your watch
  
• Tap Display & Brightness
  
• Scroll to Always On
  
• Toggle it on or off
  

When the Always-On Display Automatically Turns Off

To preserve battery or maintain privacy, the screen will turn off entirely in certain scenarios:

• When your iPhone is face down
  
• When it’s in your pocket or bag
  
• If Low Power Mode is enabled
  
• During Sleep Focus or Do Not Disturb
  
• When using CarPlay or Continuity Camera
  

This makes the feature smart—not just always on, but intelligently on.

Battery Impact of Always-On Display

A common concern is: Does Always-On Display drain the battery? The impact is minimal, thanks to Apple’s optimizations.

Apple designed AOD to consume very little power, using:

• Low refresh rates
  
• Dimmed display levels
  
• Smart context-aware shut-off
  

However, if you’re trying to extend your battery as much as possible, disabling AOD will help.

Benefits of Using Apple’s Always-On Display

Can You Customize What Appears on AOD?

• Choose specific Lock Screen widgets
• Select a wallpaper style
• Enable or disable notification previews
• Set up Focus modes that interact with AOD
  

Apple Watch also offers customization through Watch Faces and complications that adapt to AOD.

Common Issues and Fixes
