Owners of the popular Xiaomi Redmi Note 8T often face the need to keep the display on for a long time. This may be required when reading e-books, viewing circuits during repairs, using the smartphone as a desktop clock or navigator. Standard MIUI energy saving settings aggressively extinguish the screen to save battery power, which creates discomfort in specific use scenarios.
The solution to this problem is not always obvious, because manufacturers intentionally limit the maximum backlight time. In this article, we will examine all available methods, from standard system settings to advanced developer tools, learn how to bypass system limitations and get the Redmi Note 8T to ignore idle timers.
It is important to understand that the constant operation of the display at maximum brightness can lead to accelerated wear and overheating of the matrix, but with the right approach and temperature control, you can safely operate the smartphone in the mode of “perpetual” screen.
Timeout settings in MIUI
The first step should always be to check the basic system parameters. In the MIUI shell installed on the Redmi Note 8T, the path to screen settings may be slightly different from stock Android. Standard time range is usually limited to a few minutes, but this is the minimum necessary to start a configuration.
To find these options, you need to open the main menu and go to the settings section. Here you are interested in the unit responsible for the visual design and display. The interface may vary depending on the firmware version (Global, EU or China), but the logic remains the same.
- 📱 Open the Settings app on the main screen.
- 🔍 Find and select the screen and brightness (or just the screen).
- ⏱️ Click on the option Sleep Mode or Time Out screen.
- ⚙️ Choose the maximum value available, usually 5 minutes or 10 minutes.
Unfortunately, Xiaomi rarely allows you to set a “Never” value or more than 10 minutes with standard means, which is done to prevent pixel burnout and maintain autonomy. If you need more time, you will have to resort to additional methods described below.
💡
Use the brightness boost feature only when necessary, as on the Redmi Note 8T it significantly speeds up battery discharge in continuous on mode.
Use of the developer mode
The Android developer’s hidden menu contains debugging tools that can help control screen behavior. For the Redmi Note 8T, activating this mode opens up options that are hidden from the average user. It’s a secure system method that doesn’t require root rights.
The developer mode is activated by repeatedly clicking on the build number, and then a new section will appear in the settings menu where you can find useful options, and in particular, we are interested in a feature that prevents you from going to sleep during charging.
☑️ Activation of the developer mode
In the menu that opens, you scroll down to the Debugging block, and here's the "Stay awake" option, and when activated, the Redmi Note 8T display will not go out while the device is connected to the power source, which is the perfect solution for using the smartphone as a stationary panel.
⚠️ Warning: Turning this feature on when using non-original chargers can cause the power controller to overheat.
Always on Display and its impact
Technology Always on Display (AOD) It allows you to display time and notifications on the screen off. on Xiaomi Redmi Note 8T s AMOLED-This is a software-based function that can be configured to run on a schedule, and although this doesn't keep the main interface active, it prevents the backlight from completely quenching at certain hours.
To set up, go to Settings → Wallpaper and Personalization → Always on screen, where you can choose the display style and, most importantly, the time interval, you can set a period, for example, from 8:00 to 23:00, when the screen will constantly display information.
AOD is less energy-intensive than full mode, but still battery-intensive. The Redmi Note 8T has a variety of styles, including digital watches and animations. Some styles can be optimized better than others, so it's worth experimenting with the design.
Third-party screen management applications
If system constraints aren't enough, specialized apps from the Google Play Store come to the rescue, run on top of the system and force you to stop going to sleep, and the Redmi Note 8T is a good fit for applications with minimal resource consumption.
One popular solution is the "Keep Screen On" app, or analogues, which, when you install it, you have a floating button or switch in the notification curtain on the screen, and you press it to block the sleep timer until you turn it off.
When choosing an application, pay attention to the permissions requested. They have the right to “Prevent Sleeping Mode” to work. If the application requires access to contacts or geolocation, it is suspicious and it is better to abandon such a program for the sake of data security.
- 📥 Download a proven app, such as Keep Screen On or Caffeine.
- 🔐 Provide the minimum permissions required at the first launch.
- 🔘 Add a widget or shortcut to the Quick Access Panel for convenience.
- ⚡ Use the function only when it is really necessary.
Specificity of the AMOLED matrix
The Redmi Note 8T screen is built on AMOLED technology, which means that each pixel is individually illuminated, and in a static image at high brightness, there is a risk of burnout, the appearance of a residual image that cannot be removed software.
To minimize the risks of long screen operation, it is recommended to use dark themes. AMOLED-The matrices are actually turned off and do not consume energy, and are not subject to degradation.
| Parameter | Impact on AMOLED | Recommendation for the Redmi Note 8T |
|---|---|---|
| Brightness | High brightness accelerates the degradation of organic matter | Reduced to 30-40% with static content |
| Staticity | Fixed elements burn out faster | Use screensavers with moving elements |
| Temperature. | Heating above 45°C is harmful to the matrix | Remove the cover during long work |
| Content. | White background consumes maximum energy | Include a dark theme of the system |

Automation through Tasker and macros
For advanced users, automation is the best solution, and applications like Tasker or MacroDroid allow you to create a scenario where the screen doesn't go out just when you run a particular application or connect to a Wi-Fi network, eliminating the need to constantly monitor your settings manually.
For example, you can set up a macro: "If you run a Navigator or Reader app, set a screen timeout to Never, otherwise you can return the standard 30 seconds, which provides a balance between convenience and energy efficiency."
It takes time to set up these scenarios, but it's worth it. You get a flexible system that adapts to your actions. This is especially true for the Redmi Note 8T, because the regular MIUI functionality isn't always flexible in power management.
⚠️ Note: When using automation, make sure the system is allowed to run in the background. Check the battery settings for the automation application and select "No restrictions».
