Budget smartphone owners often wonder how to optimize the device in low light. For Xiaomi’s Redmi 9, this is especially important, as IPS-type screens require proper calibration to reduce eye strain. In this article, we will discuss in detail all available methods for activating “dark theme” and specialized shooting modes.
Understanding the difference between system settings and camera features will allow you to make the most of the gadget. Night mode can mean both inversion of interface colors and algorithms for improving photos in low light. We will consider both options so that you do not have any questions after reading the material.
Activation of dark theme in the Android system
The first and most obvious step to make a smartphone comfortable in the dark is to switch the system interface to a dark theme.This action instantly changes the background color of menus, settings and supported apps to black or dark gray. To do this, open the Settings app and search for the Screen section.
In the menu that opens, you'll need to find Dark Mode, and once you activate the slider, the MIUI interface will change instantly, and not only does it reduce the visual load, but it also saves battery life if the screen was AMOLED, although Redmi 9 has IPS, where the savings are minimal, but visual comfort will remain high.
Additionally, you can configure the dark theme schedule so that it will be turned on automatically after sunset.
- 🌙 Open the screen settings through the notification curtain for quick access.
- 📅 Set a timer for including a dark topic in the “Schedule” section».
- 🎨 Choose the degree of dimming if your version of the shell allows customization.
Use of night mode in the Camera app
Under-light photography is a separate story that requires specialized processing algorithms. The standard Camera app on Redmi 9 has a feature that allows you to take vivid pictures even at night. To access it, run the app and scroll through the lower mode menu to the More tab.
Here you'll find Night Shooting, and when you choose this mode, the camera takes a series of different exposures and then combines them into one final image, which allows you to significantly reduce digital noise and pull details out of the shadows, which is critical for budget matrixes.
Stabilizing your hands during nighttime shooting is a must for a clear shot.
Setting up the blue light filter (Reading Mode)
The blue spectrum of screen radiation can disrupt melatonin production, leading to sleep problems. Xiaomi smartphones have an effective tool to combat this effect, often referred to as the “night mode” of the screen. Go to Settings → Screen → Vision Protection.
This section has a blue light filter intensity slider, you can manually adjust the level or trust it to the system, and Adaptive Protection is available, which changes the parameters depending on the time of day and the lighting of the environment.
⚠️ Note: When you turn on the maximum level of protection of vision, the colors on the screen can become noticeably yellower, which is normal for this function, but can interfere with graphics.
💡
For quick switching of the protection mode of vision, add the corresponding switch to the notification curtain through the editing menu of the control buttons.
Automation through schedule and alarm
Manual mode switching can be inconvenient, so MIUI offers process automation, so you can set your smartphone to go to night at a certain time, and it's not just about the alarm clock, but about the overall behavior of the device.
To set up, go to the Watch app and select the alarm clock you want. In the settings of a particular alarm clock, there is often an option called Sleep Mode or Do Not Disturb, which activates along with the wake-up or fall asleep signal, which limits notifications and reduces brightness.
An alternative way is to use the function “Digital well-being”, where you can set the mode “Sleep”.
- ⏰ Set the start and end times of the “Do Not Disturb” mode».
- 🔇 Set up exceptions for selected contacts to avoid missing an important call.
- 🌗 Synchronize sunset and sunrise times to automatically change the subject.

☑️ Checking screen settings
Third-party applications and advanced settings
If standard MIUI 12 or more is not enough, you can always turn to third-party solutions. There are many applications in the Google Play store that allow you to darken the screen below the minimum threshold set by the manufacturer.
One popular solution is to use applications with a translucent black layer overlay, which makes the Redmi 9 screen virtually invisible in total darkness, but it's worth remembering that these applications consume additional CPU resources.
⚠️ Note: Install applications from unknown sources or modified versions of system APK It can lead to unstable operation of the smartphone.
Risks of using third-party filters
Features of the Redmi 9 display in the dark
The Redmi 9 screen has a resolution of 1080×2340 pixels and is made using IPS technology. Unlike AMOLED-matrixes, black here is displayed as dark gray, since the backlight is constantly working, which is an important nuance to consider when setting up night modes.
At low brightness on IPS-Sometimes there is a "glow" effect on the screens or uneven lighting around the edges. Using a dark theme helps to hide this defect, making it less noticeable to the human eye.
