Daytime mode on Xiaomi: what it is, how it works and why you need it

If you own a Xiaomi, Redmi or POCO smartphone, you've probably encountered the term "day mode" in your screen settings. But what does it really mean? Many users confuse it with night mode or adaptive brightness, although the features of these options are completely different. In this article, we'll take a look at how day mode works on Xiaomi devices, how it differs from other screen modes and how to adjust it correctly for comfortable use.

The concept of day mode appeared in firmware MIUI It's a response to users who want a more natural color reproduction in bright light, and unlike night mode, which reduces blue light in the evening, daytime mode adjusts color temperature and contrast according to environmental conditions. This is especially true for modern AMOLED-screens that are prone to excessive saturation of colors in sunny weather.

It's important to understand that daytime mode is not just a marketing feature, but a really useful feature that can reduce eye strain when using a smartphone on the street for a long time. However, not all users know how to activate and configure it correctly. Next, we will look at all the nuances of this feature, including hidden settings that are not obvious at first glance.

What is Xiaomi’s Daytime Mode and How Does It Work?

Daylight Mode (International firmware) is a color-correction technology that automatically adjusts screen settings to indoor or outdoor lighting, and unlike standard brightness settings, it affects three key parameters:

• 🔹 Color temperature – shifts shades towards warmer or cooler tones depending on the surrounding light
• 🔹 Contrast – Increases the difference between light and dark areas for better readability in bright light
• 🔹 Color saturation – adjusts the intensity of the colors to make them look natural under different conditions

The technology is based on data from a light sensor and ambient color sensor (if you have one in the model), the algorithm analyzes the intensity and spectrum of incident light, and then applies optimal screen settings, for example, in cloudy weather, the screen will become slightly warmer, and in direct sunlight - colder and contrast.

It’s important to note that daytime mode works regardless of automatic brightness. You can use them together or separately. On the new Xiaomi 14 and Redmi K70 flagships, this feature is integrated with AdaptiveSync, which further optimizes the screen refresh rate to save battery life.

⚠️ Note: On budget models (e.g. Redmi) A2 or POCO M6) The daytime mode can be simplified, without analyzing the color spectrum, only according to the light sensor.

Differences between daytime and nighttime and adaptive brightness

Many users confuse these three functions, even though they solve completely different tasks.

The main difference between daytime mode is that it doesn't just make the screen brighter or darker, it changes the color palette itself, for example, in bright sunlight it will add cold shades to compensate for the yellow light of the sun, and in a room with warm light, on the contrary, it will soften the colors.

Interesting fact: on Xiaomi smartphones with Dolby Vision support (for example, Xiaomi 13 Ultra), the day mode can automatically switch between Vivid and Movie profiles depending on the lighting conditions.

How to turn on and configure day mode on Xiaomi

You can activate the day mode in several ways, depending on the version of MIUI. Consider the universal method that works on most devices:

1. Open the settings → Screen
2. Select Day Mode (or Daylight Mode in Global Firmware)
3. Activate the switch at the top of the screen
4. If necessary, set up additional parameters: 🔘 Automatic turn on – on schedule or at a certain level of illumination 🔘 The intensity of the effect - from minimal to maximum correction 🔘 Exceptions – you can disable the mode for specific applications

On some models (e.g. POCO F5), the path may be slightly different: Settings → Display → Color Mode → Day Mode. If you don’t find this item, maybe your model doesn’t support the feature, check the specifications on the official website.

To fine-tune it, we recommend using Manual Adjustment, where you can see in real time how colors change at different values, which is especially useful for photographers and designers who care about color reproduction.

Hidden opportunities of the day mode, which you did not know

Besides the basic features, the daytime mode on Xiaomi has several hidden features that can greatly improve the experience:

• 🎨 Profiles for different conditions – on flagships (Xiaomi 14 Pro, Mix Fold 3) you can save separate profiles for the office, street and home
• 🔄 Quick switching – add tile to the notification bar for instant on/off
• 📊 Use statistics – in the settings you can see how long the mode was active per day
• 🔒 Blocking settings – protection against accidental changes (useful for parental control)

One of the most useful hidden functions is calibration for specific lighting.

1. Turn on the daytime routine.
2. Place your smartphone in the usual conditions (for example, on the desktop)
3. Click the mode icon in the notification panel
4. Select Calibration for Current Lighting

After that, the system will remember the optimal settings for these conditions and apply them automatically, a feature that is especially useful for people who spend a lot of time in one place (office, classroom).

⚠️ Note: On custom firmware devices (such as LineageOS or Pixel Experience), daytime mode may not work properly or at all. This is due to proprietary Xiaomi algorithms that are not ported to third-party builds.

Problems with the day regime and how to solve them

Despite the obvious benefits, some users face problems when using day mode, and consider the most common ones and how to fix them:

• 🔴 The screen is too cold/warm – adjust the intensity in the settings or recalibrate
• 🔴 Mode turns on at inappropriate times – check schedule settings or turn off automatic turn on
• 🔴 Does not work on some applications – add the app to exceptions or update it
• 🔴 Battery goes down quickly – turn off constant light monitoring in additional settings

If the daytime mode has stopped working completely after the MIUI update, try the following steps:

1. Clear the Settings app cache (Settings → Applications → Application Management → Settings → Clear the cache)
2. Reset the screen settings to factory settings (Settings → Screen → Additional → Reset screen settings)
3. Check the light sensor with the engineering menu (#6484## → Sensor Test)

In the models with AMOLED-screens (e.g. Xiaomi) 13T) Sometimes there's a problem with flickering when you're in the daytime mode, and that's because of the conflict between the technology. DC Dimming and color correction. The solution is to disable. DC Dimming in screen settings or updating firmware.

Daytime mode on different Xiaomi models: what has changed

Day mode technology has evolved with MIUI firmware, and let’s look at how it’s implemented across generations of devices:

Since MIUI 14, daytime has become more intelligent, taking into account not only light levels, but also time of day, geolocation (to determine weather conditions), and even user activity, for example, if you stare at a screen in a dark room for a long time, the system can automatically reduce the intensity of the correction, even if the mode is on.

On foldable smartphones Xiaomi Mix Fold day mode works separately for the internal and external screen, as they have different specifications, which allows you to optimize the color reproduction depending on which screen is used at the moment.

💡

If you have a smartphone with AMOLED-screen (Xiaomi 13 Pro, Redmi) K60 Include Adaptive refresh rate in the screen settings with day mode, which will further save battery power in bright light, as the screen will automatically switch to a lower refresh rate whenever possible.

Daytime regime and eye health: myths and reality

Many users think that daytime is good for eye health, but is that really true? Let's look at it scientifically.

Health benefits:

• ✅ Reduces visual fatigue during prolonged work with the device on the street
• ✅ Reduces contrast load on the eyes in variable lighting conditions
• ✅ Helps to avoid headaches caused by incorrect color reproduction

Myths and misconceptions:

• ❌ "Daytime regimen protects against myopia" - there is no scientific evidence that color correction affects the development of myopia
• ❌ "It completely replaces sunglasses, it’s an addition, not an alternative.
• ❌ "The mode is harmful to the screen – modern AMOLED-The panels do not deteriorate from color correction

Ophthalmologists recommend using the daily regimen in combination with other measures:

1. Follow the 20-20-20 rule (watch an object 20 feet (6 meters) for 20 seconds every 20 minutes)
2. Adjust the distance to the screen (optimally - 30-40 cm)
3. Use wet eye drops for long periods of work

Interestingly, MIUI 14 has a Reminder for Eye Health feature that works in sync with daytime mode, which not only adjusts colors, but also reminds you to take a break if you look at the screen for too long in bright light conditions.

💡

Daytime exercise is not a medical treatment for vision, but it can significantly improve comfort when using a smartphone during the daytime. For maximum effect, combine it with other methods to prevent visual fatigue.
