The always-on display (AOD) feature has revolutionized the way we interact with our smartphones. This innovative technology allows users to glance at their phone’s screen without having to wake it up, providing a convenient and power-efficient way to stay informed. In this article, we’ll delve into the world of always-on displays, exploring which phones have this feature, how it works, and its benefits.
What is an Always-On Display?
An always-on display is a feature that allows a phone’s screen to remain partially lit, even when the device is in a dormant state. This means that users can view essential information, such as the time, date, notifications, and battery level, without having to wake up their phone. AODs are designed to be power-efficient, using minimal battery life while still providing a convenient way to stay informed.
How Does an Always-On Display Work?
Always-on displays work by using a combination of hardware and software technologies. Here’s a breakdown of the process:
- Display Technology: AODs typically use OLED (Organic Light-Emitting Diode) or AMOLED (Active Matrix Organic Light-Emitting Diode) display panels. These panels are designed to produce true blacks, which helps to conserve battery life.
- Power Management: The phone’s power management system is responsible for controlling the AOD feature. When the phone is in a dormant state, the power management system reduces the screen’s brightness and limits the amount of power consumed.
- Software Integration: The phone’s operating system and software work together to provide the AOD feature. The software is responsible for displaying the relevant information on the screen, such as the time, date, and notifications.
Which Phones Have Always-On Displays?
Many modern smartphones come equipped with always-on displays. Here are some of the most popular phones that feature AODs:
- Samsung Galaxy Series: Samsung’s flagship Galaxy series, including the S22, S21, and Note 20, all feature AODs.
- Google Pixel Series: Google’s Pixel series, including the Pixel 6, Pixel 5, and Pixel 4, all come with AODs.
- OnePlus Phones: OnePlus phones, such as the OnePlus 9, OnePlus 8, and OnePlus 7, feature AODs.
- Huawei Phones: Huawei phones, such as the P30, P20, and Mate 30, come with AODs.
- Xiaomi Phones: Xiaomi phones, such as the Mi 11, Mi 10, and Redmi Note 10, feature AODs.

Whether you’re looking for a convenient way to stay informed or a power-efficient way to conserve battery life, always-on displays are an excellent choice.
What is an always-on display, and how does it work?
An always-on display is a feature that allows a phone’s screen to remain partially lit, even when the device is locked or in a low-power state. This allows users to quickly glance at information such as the time, date, and notifications without having to fully wake up the device. The always-on display typically uses a low-power mode to conserve battery life, and it can be customized to show different types of information and to turn on and off at specific times.
The always-on display works by using a combination of hardware and software to minimize power consumption while still providing a visible image on the screen. The display is typically dimmed to a very low brightness, and the phone’s processor is put into a low-power state to conserve energy. The phone’s operating system is also optimized to only update the display periodically, rather than continuously, to further reduce power consumption.
Which phones have an always-on display feature?
Many modern smartphones have an always-on display feature, including devices from Samsung, Google, OnePlus, and Apple. Some examples of phones with always-on displays include the Samsung Galaxy S22 series, the Google Pixel 6 series, the OnePlus 9 Pro, and the Apple iPhone 14 Pro. It’s worth noting that not all phones from these manufacturers have always-on displays, so it’s a good idea to check the specifications of a particular device to see if it has this feature.
In addition to these flagship devices, some mid-range and budget phones also have always-on displays. For example, the Samsung Galaxy A52 and the Google Pixel 5a both have always-on displays, despite being more affordable than some of the other devices on the market. As the technology becomes more widespread, it’s likely that we’ll see even more phones with always-on displays in the future.
How does an always-on display affect battery life?
The impact of an always-on display on battery life can vary depending on the specific device and how the feature is used. In general, an always-on display can consume a small amount of power, which can reduce the overall battery life of the device. However, many modern phones are designed to minimize the power consumption of the always-on display, and some devices can even use the feature to help extend battery life by reducing the need to fully wake up the device.
According to some studies, an always-on display can consume around 1-2% of the device’s battery life per hour, although this can vary depending on the specific device and usage patterns. To put this in perspective, if you use your phone for 16 hours a day, an always-on display might reduce your battery life by around 16-32 minutes. However, this is just an estimate, and the actual impact on battery life will depend on many factors, including the device, usage patterns, and other settings.
Can I customize the always-on display on my phone?
Yes, many phones with always-on displays allow you to customize the feature to some extent. For example, you may be able to choose what information is displayed on the screen, such as the time, date, and notifications. You may also be able to adjust the brightness and timeout of the always-on display, as well as schedule it to turn on and off at specific times.
Some phones also offer more advanced customization options, such as the ability to add custom widgets or images to the always-on display. For example, the Samsung Galaxy S22 series allows you to add custom images and widgets to the always-on display, while the Google Pixel 6 series offers a range of customization options through the Google Launcher. It’s worth checking your phone’s settings to see what customization options are available.
Is an always-on display available on all screen types?
Not all screen types are compatible with always-on displays. For example, LCD screens typically do not support always-on displays, as they require a backlight to be turned on in order to display an image. However, OLED and AMOLED screens are well-suited to always-on displays, as they can turn individual pixels on and off to create an image without requiring a backlight.
As a result, many phones with always-on displays use OLED or AMOLED screens. These screens are not only more power-efficient than LCD screens, but they also offer better contrast and color accuracy. However, it’s worth noting that some LCD screens may offer a similar feature, such as a “breathing light” that pulses on and off to indicate notifications.
Can I turn off the always-on display on my phone?
Yes, you can typically turn off the always-on display on your phone if you prefer not to use it. The process for doing so will vary depending on the device and operating system, but it’s usually a simple matter of going into the phone’s settings and toggling off the always-on display feature.
For example, on a Samsung Galaxy S22, you can turn off the always-on display by going to Settings > Lock screen > Always On Display, and then toggling off the switch. On a Google Pixel 6, you can turn off the always-on display by going to Settings > Display > Lock screen > Always show time and info, and then toggling off the switch. It’s worth noting that turning off the always-on display can help extend battery life, although the impact will likely be small.
Are there any security concerns with always-on displays?
There are some potential security concerns with always-on displays, although these are generally relatively minor. For example, if your phone is set to display sensitive information on the always-on display, such as notifications or calendar events, this information could potentially be visible to others if they glance at your phone.
However, most phones with always-on displays offer features to help mitigate these risks, such as the ability to hide sensitive information or to require a PIN or fingerprint to unlock the device. Additionally, many phones will automatically turn off the always-on display when the device is in a pocket or bag, or when it is in a location where it is likely to be private. As with any feature, it’s a good idea to review the settings and options for your phone’s always-on display to ensure that you are comfortable with the level of security it provides.
