Function Always On Display, often called ACR or AOD by users, has become a standard for modern smartphones, allowing you to see the time and notifications without completely waking up the device. However, owners of gadgets running Android 10 sometimes encounter difficulties in activating this option, since its presence and location in the menu are highly dependent on the shell manufacturer. In this article, we will look in detail at how to find and configure the mode for constantly displaying information on the screen.
It is worth noting right away that not all smartphones support this technology in hardware. For correct operation ACR you need a display built using OLED or AMOLED technology, where each pixel is individually illuminated. If your device is equipped with an IPS matrix, the system may not offer this feature at all, or it will operate in a reduced mode with high power consumption. Understanding this limitation will save you time searching for non-existent switches in the settings.
We will look at various enablement scenarios: from standard system tools to using third-party utilities if the manufacturer has hidden this feature. We will also touch on the issues of optimizing energy consumption so that the beautiful interface does not drain the battery in a matter of hours. Ready to turn your black screen into a dashboard? Let's start by checking the basic settings.
Checking hardware compatibility and screen type
The first step before attempting to activate any always-on display feature is to verify the technical specifications of your smartphone. The mode Always On Display critically depends on the type of matrix, since the principle of its operation is to light only a small number of pixels on a black background. On IPS screens, the backlight works constantly over the entire area, which makes the implementation of ACR inefficient and excessively energy-consuming.
To find out the type of your screen, you can use specialized applications from the store Google Play, such as Device Info HW or AIDA64. In the "Display" or "Screen" section, look for mention of technologies OLED, AMOLED or POLED. If it says IPS, TN or LCD, then the native ACR function is most likely not available to you without obtaining root access and deep modification of the system, which is not recommended for ordinary users.
Even with an OLED matrix, some budget models may have software restrictions on the part of the vendor. Manufacturers often reserve this feature for flagship lines to boost sales of more expensive devices. Therefore, having a suitable screen is a necessary, but not always sufficient condition for the function to work out of the box. Android 10 may have software restrictions on the vendor's side. Manufacturers often reserve this feature for flagship lines to boost sales of more expensive devices. Therefore, having a suitable screen is a necessary, but not always sufficient condition for the function to work out of the box.
⚠️ Attention: Attempts to enable ACR on IPS screens through third-party applications will lead to rapid burnout of the matrix and critical battery discharge in 2-3 hours. Make sure you have the display type before installing the software.
Activation through standard system settings
In most cases, if a function is supported by your device, it is hidden deep in the system menu. The interface Android 10 provides a single framework of settings, but each manufacturer (Samsung, Xiaomi, OnePlus, Motorola) arranges the items differently. Start your search from the main settings menu using the built-in search options.
Enter the query “Always-on screen”, “AOD” or “Active Display” in the settings search bar. The system should redirect you directly to the desired switch. If the search does not produce results, try manually following the following typical paths that are found in popular shells:
- 📱 Samsung One UI: Settings → Lock screen → Always On Display.
- 📱 Xiaomi MIUI: Settings → Always on screen and lock.
- 📱 OnePlus OxygenOS: Settings → Personalization → Always On Display.
- 📱 Motorola My UX: Settings → Display → Active display.
After finding the item Always On Display activate the toggle switch. Often, immediately after switching on, an additional configuration menu appears, where you can select the clock style, color and information displayed. Do not ignore these settings, as not only aesthetics, but also battery consumption depend on them.
Setting the ACR schedule and operating conditions
Continuous operation of the display, even in economy mode, affects battery life. To balance convenience and autonomy, the system Android 10 and vendor add-ons offer flexible activation scenarios. The most popular mode is scheduled operation, when the screen lights up only during the hours of your activity, for example, from 8:00 am to 11:00 pm.
In the ACR settings menu, find the item "Schedule" or "Operating time". Here you can set specific time intervals. This is especially useful for keeping the screen lit all night when you're sleeping and don't need to check notifications. Some implementations allow you to select the "From Dusk to Dawn" mode, using geolocation to determine the time of day.
Another important parameter is the response to user actions. You can set the screen to turn on only when you receive a new notification or when you pick up your smartphone. The mode "Touch to show" is the most energy efficient: the screen remains black until you touch it, displaying information for 10-20 seconds.
Use the "Scheduled" mode with an interval of 7:00–23:00 to save up to 15% of the charge batteries overnight, eliminating display operation in the dark.
Experiment with combinations of settings to find the perfect balance. If you frequently check your phone at night, leave the mode on, but reduce the brightness. If the smartphone is during the day, the “When picked up” mode will be the best choice.
Using third-party applications to emulate ACR
If your manufacturer has not implemented a native function in Android 10, but the device screen meets the specifications, the situation can be corrected using third-party software. There are many applications in the Google Play store that emulate the Always On Display with high efficiency. One of the most popular and reliable solutions is the application Always On AMOLED.
Once you install such an application, you will need to grant it certain permissions, including the right to display on top of other windows and access to usage data. This is necessary so that the app can intercept screen-on and lock events, replacing the standard screensaver with its own interface. The setup process is usually intuitive and takes no more than a couple of minutes.
It is important to note that third-party applications may consume slightly more resources than their system counterparts due to the way they work in the background. However, modern optimization algorithms can minimize this impact. Before use, carefully study the reviews and requirements of a specific application for the OS version.
⚠️ Attention: Third-party applications for ACR require constant work in the background. Add them to the list of exceptions of the power saving system ("Do not limit"), otherwise Android 10 may forcefully close the process and the screen will not light up.
Fine-tuning content and display styles
Visual component ACR plays an important role in perception. The standard clock is a classic, but modern implementations allow you to display much more useful information on the lock screen. In the style settings, you can choose to display a calendar, pedometer, battery level, or even the cover of the playing track.
Pay attention to the brightness of the display. The settings menu often contains a slider or automatic mode for adjusting the AOD brightness. For nighttime, it is recommended to set the value to the minimum so that the luminous pixels do not dazzle the eyes and create the effect of “light pollution” in the bedroom. During the day, the brightness can be increased for better readability.
Some shells, such as One UI from Samsung, allow you to upload your own images or GIFs as a background for the Always On Display. This personalizes the device, but it is worth remembering that complex animations and light colors in the background significantly increase power consumption. For maximum autonomy, use a black background and white or colored thin fonts.
Why does a black background save battery?
In OLED matrices, black means the pixel is completely turned off. The more black area on the screen when AOD is enabled, the less power the display consumes. Bright and white pixels consume maximum energy.
Diagnosis of problems and impact on the battery
Users are often concerned that turning on Always On Display will lead to rapid discharge of the smartphone. The reality is that on modern devices with capacious batteries and optimized software, the consumption is approximately 0.5% - 1% per hour, depending on the number of active pixels. For comparison, background processes of instant messengers and synchronization can consume the same amount.
If you notice an abnormally high discharge after enabling ACR, check the battery usage statistics in the system settings. Perhaps some application is abusing screen wakening or the function is not working correctly. Also make sure that you do not have the “Continuous backlight” mode without timeout enabled, if such an option is available in third-party software.
The table below shows approximate energy consumption data for different ACR operating modes on a standard 4000 mAh battery:
| Operating mode | Description | Approximate consumption for 12 hours |
|---|---|---|
| Always on | The screen is constantly on | 6% – 8% |
| According to schedule | Work 12 hours a day | 4% – 5% |
| When touched | Turn on for 10 seconds by tap | 1% – 2% |
| When notification | Only for new events | 2% – 3% |
To extend battery life, it is recommended to use hybrid scenarios. For example, turn on AOD on a schedule during the day, and at night use the “On Touch” mode or disable the function altogether. This will allow you to maintain the information content of the interface without sacrificing autonomy.
☑️ Optimizing AOD operation
Frequently asked questions (FAQ)
Does Always On Display affect Screen burn-in (Burn-in)?
Modern OLED matrices are protected against burn-in, including periodic pixel displacement by several points. With moderate use and automatic brightness adjustment, the risk is minimal. However, a static image at maximum brightness for months can leave a mark.
Why is there no "Always On Display" option on my Android 10?
Most likely, your smartphone uses an IPS matrix, which does not technically support the economical display of individual pixels. Or the manufacturer has programmatically disabled this feature for your model. Check the screen type through the Device Info HW application.
Can you customize your own image for AOD?
Yes, many third-party applications (for example, Always On AMOLED) allow you to upload your own images. In stock firmware, this feature is often limited to a set of preset clocks and animations, although some brands (Samsung, LG) allow you to add your own photos.
Will AOD work if the phone is face down?
In most implementations, the proximity sensor or accelerometer determines the position of the phone. If the device is face down or in a pocket, the backlight ACR automatically turns off to save energy and prevent accidental clicks.
How to disable AOD if it has started to irritate?
Go to Settings → Display (or use search settings), find the item Always On Display and turn the switch to the "Off" position. If you were using a third-party application, simply uninstall it or revoke the rights to display on top of other windows.
Key takeaway: Always On Display is a safe and useful feature for OLED screens that, when properly scheduled, consumes less than 5% of the battery per day.
