Setting the screen fade time on Xiaomi: all ways

Xiaomi’s smartphone screen is one of the world’s most powerful energy consumers, and automatically turning off when inactive helps save battery power. However, standard fade-time settings (usually 30 seconds) aren’t always convenient: some need more time to read, others need instantaneous shutdown for security. In this article, we’ll look at all the ways to change the screen auto-out interval on MIUI devices, from basic settings to hidden features for advanced users.

It is important to note that the screen algorithm does not depend only on the version. MIUI, But also from a smartphone model. For example, on the Xiaomi 13 Pro with AMOLED-The display settings may differ from the Redmi Note 10 with IPS-We will look at universal methods that are relevant to most of the brand’s devices, including: POCO and Black Shark.

Why it is important to properly adjust the screen fade

The time of automatic display shutdown affects three key aspects:

• 🔋 Autonomy: The longer the screen stays on unnecessarily, the faster the battery runs out. For example, at intervals of 1 minute instead of 30 seconds, energy consumption can increase by 15-20% per working day (test data from Xiaomi Lab).
• 🔒 Security: Short fade time reduces the risk of unauthorized access if you forget to lock your phone.
• 👁️ Convenience: Too fast a shutdown interferes with reading long articles or viewing photos, and too long leads to accidental touches in your pocket.

The manufacturer defaults to balancing these factors, but the best settings depend on your use case, such as for office work, it is convenient to increase the interval to 2-5 minutes, and for the street to reduce to 15 seconds.

Method 1: Standard MIUI settings

The easiest method is to change the settings menu.It works on all Xiaomi devices with MIUI 12 and later, including Redmi, POCO and Black Shark.

1. Open the Settings app (the gear icon on the desktop).
2. Go to Always Active Screen and Lock (on some models – Lock Screen).
3. Select Sleep Mode (or Auto-Switch Off Screen).
4. Set the desired interval: from 15 seconds to 10 minutes (on some firmwares, the value of Never is available).

Note: If there is no option on the list (e.g., 2 or 5 minutes), this will limit your version of MIUI.

💡

On smartphones with AMOLED-screens (for example, Xiaomi 13 Ultra) long-term extinction time is less critical for the battery than on the battery IPS-The technology is always-on display (AOD).

Method 2: Using the Developer Mode

For users who need to adjust the screen behavior more accurately (for example, set non-standard time or turn off fading when charging), the Developer Menu will be suitable.

1. Open the Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row (you will be notified “You became a developer”).
3. Return to the main settings menu and select a new section → For developers.

Now you can:

• 🛠️ Change screen waiting time – values up to 30 minutes are available here (on some firmware).
• 🔌 Disable fade when connecting to charging (option Do not turn off the screen when charging).
• 📱 Set separate settings for the mode Do not disturb.

Activate Developer Mode (7 taps according to MIUI)

Backup settings (Settings → Additional → Backup)

Check the battery power (recommended >50%)

Close the background applications (to avoid conflicts)-->

Warning: Sloppy changes to the developer menu can cause sensor or auto-brightness to fail. For example, turning off the Adaptive Brightness option sometimes causes the screen to flicker on the screen. AMOLED-model.

Method 3: Configure through third-party apps

If built-in options aren't enough, you can use third-party utilities, which are useful for:

• 📱 Dynamic Extinguishing Time settings (e.g. 30 seconds on battery and 5 minutes on charge).
• 🔄 Automatically varying the interval depending on location (home/work).
• 🛡️ Locking the screen under certain conditions (for example, when the phone is down screen).

The most reliable applications for Xiaomi:

*Some Tasker activities may require ADB or Root.

⚠️ Note: Screen control applications may conflict with system services MIUI, Especially on firmware with enhanced battery optimization (e.g. Redmi Note 12) If after installing the utility, the screen flickered spontaneously or did not turn off, remove it and restart the device.

Method 4: ADB commands for advanced users

If you need to completely disable automatic screen dimming (for example, to use your phone as a monitor or media player), you can use the ADB (Android Debug Bridge) commands. This method does not require Root, but you need a computer with drivers installed.

Instructions:

1. Activate Debugging by USB in the Developer Menu.
2. Connect the phone to the PC and confirm the debugging permission.
3. Open the command line (Windows) or terminal (macOS/Linux) and type:

adb shell settings put global stay_on_while_plugged_in 3

This command will keep the screen on whenever you charge, and to return the standard behavior, do this:

adb shell settings put global stay_on_while_plugged_in 0

To completely turn off the extinction timer (even on the battery) use:

adb shell settings put system screen_off_timeout 2147483647

The value of 2147483647 corresponds to the maximum possible time (about 24 days).

Features of setting up on different Xiaomi models

Despite the common MIUI platform, some models have unique nuances:

• 📱 Xiaomi 13/14 Series: Supported by LTPO-Dynamic refresh rate displays: The expiration time can be adjusted automatically depending on the content (e.g., when watching a video, the screen stays active longer).
• 🎮 Black Shark: In Shark Space, the screen never goes out, even if the settings are short-ranged.
• 💡 Redmi with IPS-screens (e.g. Redmi) 10A): long-term (>2 minutes) matrix may overheat due to lack of Always-On technology.
• 🔋 POCO F/M-series: have a separate option Saving the charge of the screen, which forcibly reduces the time of extinction to 15 seconds at low battery level.

On foldable devices (Xiaomi MIX Fold), the fade settings may differ for the internal and external screens, for example, the external display can be set to quickly shut down (15 seconds), and the internal one can be set to 1 minute for ease of multitasking.

💡

On smartphones with AMOLED-screens (e.g. Xiaomi) 12T Pro) it is recommended to use a fade time of no more than 1 minute to avoid pixel burnout in static interface elements.

Frequent problems and their solutions

Sometimes, when you change your settings, the screen doesn't behave properly, so let's look at the typical situations and how to fix them.

⚠️ Note: If the screen flickers or turns on spontaneously after the changes, this may indicate a hardware problem with the digitizer. ADB To control the screen and contact the service center.
