- Shows time, date, widgets, and notifications in a dimmed, monochrome state.
- Requires iPhone 14 Pro models or newer Pro iPhones.
- Designed for minimal battery consumption.
This display technology is an evolution of smartphone lock screens, moving beyond mere aesthetic presentation to offer functional utility. When your iPhone is locked and idle, the Always-On Display intelligently dims the wallpaper, reduces the refresh rate of the display panel, and employs power-efficient rendering techniques to show a simplified version of your lock screen. The goal is to provide glanceable information while conserving battery life, distinguishing it from simply keeping the screen fully illuminated. It's a feature that blends aesthetics with practicality, allowing users to stay informed without constant interaction.
At its core, the feature is enabled by the ProMotion display technology found in specific iPhone models. This technology allows the display's refresh rate to dynamically adjust from a high rate down to as low as 1Hz. When the Always-On Display is active, the screen operates at this extremely low refresh rate, which drastically reduces power consumption. Furthermore, the iPhone's processor intelligently senses when the phone is placed face down, in a pocket, or when a connected Apple Watch is moved far away, and it turns the Always-On Display off to save power. These sophisticated management protocols ensure that the feature’s convenience does not come at a prohibitive energy cost.
The implications for user interaction are significant. Instead of needing to pick up your phone or tap the screen to check the time or see if a new message has arrived, you can simply glance at your device. This is particularly useful in situations where interaction might be inconvenient or impossible, such as during a meeting or while your hands are occupied. The information presented remains static and muted, designed to be unobtrusive yet readily available, providing a constant connection to your device's status without the need for full engagement.
How iPhone Always-On Display Works
What makes the iPhone's Always-On Display possible is a combination of advanced hardware and software optimizations. The ProMotion technology in the display, capable of variable refresh rates down to 1Hz, is fundamental. This low refresh rate means the screen redraws its image much less frequently, consuming significantly less power than a standard 60Hz or higher display. Coupled with an efficient processor that manages which elements are displayed and when, the system minimizes energy usage.
The iPhone uses sensors like the accelerometer and proximity sensor to detect when the screen is not needed. If the device is placed face down, it turns the Always-On Display off. Similarly, if the iPhone is put into a pocket, the display is deactivated. A particularly clever integration is with the Apple Watch: if you move your paired Apple Watch away from your iPhone, the Always-On Display will turn off to conserve battery. These contextual triggers are designed to maximize battery savings without the user needing to manually intervene.
Intelligent Screen Dimming and Content Rendering
When the Always-On Display is active, the iPhone doesn't just keep the normal lock screen lit. Instead, it intelligently adapts the display. The wallpaper is dimmed significantly, often appearing in a desaturated or monochrome tone. The time, date, and widgets are rendered with a low refresh rate, and only essential elements remain visible. Notifications that arrive will briefly appear and then fade back into the dimmed lock screen, ensuring you don't miss alerts while the display remains subtle. This selective rendering is key to the feature’s low power draw.
The operating system, iOS, plays a crucial role in managing the Always-On Display. It orchestrates the screen’s state, deciding when to activate and deactivate the feature based on various inputs. For instance, if you're using the iPhone's Focus modes, the Always-On Display will adapt its content to reflect the active Focus. When you lift the iPhone or tap the screen, it immediately transitions to the fully active, high-refresh-rate display, providing a seamless user experience. This dynamic management ensures the feature is always available when you want it, and conserves power when you don't.
The core principle is prioritizing essential information delivery with minimal power expenditure. This is achieved through hardware capabilities like the 1Hz refresh rate and software intelligence that monitors context and user activity. The system is designed to be proactive in saving battery, ensuring the convenience of an always-visible lock screen doesn't compromise your device's longevity throughout the day. The integration of sensors and the Apple Watch further enhances this intelligent power management.
Supported iPhone Models for Always-On Display
The Always-On Display feature is not available on all iPhone models. Apple introduced this capability with the iPhone 14 Pro and iPhone 14 Pro Max. Consequently, these are the first devices to natively support the Always-On Display function. Subsequent Pro models, such as the iPhone 15 Pro and iPhone 15 Pro Max, also include this feature as a standard component of their display technology.
It's important to note that the standard iPhone models, such as the iPhone 14 and iPhone 14 Plus, or the iPhone 15 and iPhone 15 Plus, do not feature the necessary hardware components, specifically the adaptive refresh rate display capable of dropping to 1Hz. Therefore, they lack the Always-On Display functionality. This distinction highlights Apple's strategy of reserving certain advanced display technologies for its premium Pro line-up, differentiating them from the base models.
Identifying Your iPhone Model's Compatibility
If you are uncertain whether your iPhone supports the Always-On Display, the easiest way to check is to look for the Pro designation in its model name. iPhones that include 'Pro' in their title, particularly from the iPhone 14 series onwards, are likely candidates. For precise verification, you can navigate to Settings > General > About on your iPhone and check the 'Model Name'. If it reads 'iPhone 14 Pro', 'iPhone 14 Pro Max', 'iPhone 15 Pro', or 'iPhone 15 Pro Max' (and any future Pro models), then your device is equipped with Always-On Display.
The absence of this feature on non-Pro models means that their screens turn completely black when locked, requiring a tap or a physical interaction to reveal the time and notifications. This is a key hardware differentiator that allows the Pro models to offer a more glanceable and continuously informative lock screen experience. The underlying display technology, which includes an advanced OLED panel and ProMotion, is what enables the Always-On Display to function efficiently.
Compatibility is strictly tied to the Pro series of iPhones. This includes the iPhone 14 Pro, iPhone 14 Pro Max, iPhone 15 Pro, and iPhone 15 Pro Max, and is expected to continue for future Pro model releases. Users of these devices benefit from the advanced screen technology that allows for a persistent, low-power display of essential information.
Managing iPhone Always-On Display Settings
For users with compatible iPhones, managing the Always-On Display is straightforward through the device's settings menu. Apple provides granular control over how and when this feature operates, allowing you to customize it to your preferences and optimize battery usage. The primary settings reside within the Display & Brightness section of the Settings app.
By default, the Always-On Display is enabled on supported iPhone models when you first set them up. However, users have the option to turn it off entirely if they find it unnecessary or if they are concerned about battery impact. To disable the feature, navigate to Settings > Display & Brightness > Always-On Display and toggle the switch off. This will revert your lock screen to a completely black state when idle.
Customizing What Appears on the Always-On Screen
Beyond simply turning the feature on or off, you can also customize the behavior of the Always-On Display. For example, you can choose to hide notifications when the screen is dimmed, or disable the display of wallpaper. These options allow for a more minimalist lock screen experience if desired. To access these further customizations, go to Settings > Display & Brightness > Always-On Display. Here, you can toggle options such as 'Show Wallpaper' and 'Show Notifications'.
You can also configure the Always-On Display to turn off when certain Focus modes are active.

Always-On Display and Battery Life
A common concern with any feature that keeps the screen active is its impact on battery life. Apple has engineered the Always-On Display to be as power-efficient as possible, but it does consume some battery power. The exact impact varies depending on usage patterns, screen brightness when the phone is active, and how many notifications you receive. However, for most users, the battery drain is minimal and manageable, especially when compared to the convenience it offers.
The technology behind Always-On Display is designed to minimize energy consumption. The ProMotion display's ability to drop to a 1Hz refresh rate is crucial, as is the intelligent dimming and desaturation of the screen content. Furthermore, the system is programmed to turn off the display entirely in certain situations, such as when the iPhone is face down, in a pocket, or when the paired Apple Watch is removed. These measures significantly reduce power draw when the Always-On Display is not providing essential utility.
Estimating Battery Consumption
While Apple does not provide an exact percentage for Always-On Display battery drain, independent testing and user reports suggest it can range from 1% to 5% of the total battery capacity over a 24-hour period. This figure can fluctuate. For example, if the phone is constantly receiving notifications, or if the ambient light sensor is tricked into thinking the environment is darker than it is (causing the display to be brighter than intended in its dimmed state), battery consumption might be slightly higher. Conversely, if the phone is not actively being used and is in a pocket or face down for extended periods, the drain will be negligible.
The power consumed by the Always-On Display is accounted for separately in the Battery settings. You can check Settings > Battery to see 'Display & Brightness' usage, which includes the Always-On Display. This allows you to monitor its impact directly and make informed decisions about managing your iPhone's power. If battery life is a critical concern, you can always disable the Always-On Display entirely through the Display & Brightness settings.
