How to remove the shutter speed on the Xiaomi phone: turn off the screen timeout forever

Screen shutter speed (or timeout) on Xiaomi smartphones is the automatic shutdown of the display after a predetermined period of inactivity. The default system sets the value from 15 seconds to 5 minutes, but many users want to completely remove the shutter speed — for example, to read long articles, view recipes in the kitchen or use the phone as a navigator. In this article, we will discuss all working ways to turn off shutter speed, including hidden MIUI settings and methods for advanced users.

It is important to understand that completely shutting down the shutter speed increases battery consumption by 12-25% depending on the model (data from the Xiaomi Redmi Note 12 Pro+ and POCO F5) tests. If you need to temporarily lock the screen, use the Always On Display (AOD) function or special applications from Google Play.

1. Standard method: screen settings in MIUI

The easiest method is to change the shutter time through system settings. It works on all Xiaomi, Redmi and POCO models with MIUI 12 and later (including HyperOS).

1. Open the Settings app (the gear icon on the desktop).
2. Go to the Screen section (or Display on some firmware).
3. Select the "Sleep" option after (or "Screen Shutter").
4. Set the maximum value of 30 minutes or Never (if available).

On some devices (such as the Xiaomi 13T Pro), the option may never be missing. In this case, select 30 minutes, which is the maximum possible value through standard settings.

⚠️ Note: On smartphones with AMOLED-screens (e.g. Xiaomi 14 or Redmi) K60 Ultra) the constant operation of the display without shutter speed can lead to pixel burnout during prolonged display of static elements (navigation panel, notification icons).

2 Hidden MIUI settings: Increase timeout to maximum

If the standard settings do not have the option Never, you can use the hidden MIUI Hidden Settings menu.This method works on most devices with MIUI 13/14 firmware and HyperOS, but requires the activation of the developer mode:

1. Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version (you will receive a notification "You became a developer").
2. Go back to the main settings menu and open a new section for developers.
3. Find the Remain active option (or Sleep timeout in English firmware) and set the value Never.

If you don’t have a Remain active option, try an alternative path:

Settings → Special features → Special features settings → Wait time before turning off the screen

3.Use of ADB: Complete shutdown of shutter speed

For users who are ready to work with Android Debug Bridge (ADB), There's a way to permanently remove the shutter speed, even on models that are not allowed by the manufacturer. USB-cable.

First set up. ADB-Drivers and turn on debugging by USB phone-on:

1. In Settings → For developers, activate debugging over USB.
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 causes the screen to remain on when you connect to the charger. To turn off the shutter speed completely (including battery life), use:

adb shell settings put global screen_off_timeout -1

⚠️ Attention: After application ADB-In order to return the standard settings, some system applications (for example, Mi Fit or Xiaomi Cloud) may stop working correctly. screen_off_timeout 30000 (where 30000 — time in milliseconds, equivalent 30 second).

4 Apps from Google Play: Alternative Solutions

If you don't want to go through settings or use ADB, you can install specialized applications that don't turn off shutter speed at the system level, but emulate user activity, preventing the screen from turning off.

• 🔹 Keep Screen On is a simple utility with a widget for quickly turning on / off the function.
• 🔹 Caffeine - Adds a button to the notification panel to temporarily turn off shutter speed. MIUI 14 and HyperOS.
• 🔹 Stay Alive – Advanced settings to control screen timeout and lock while charging.

The downside of these apps is that they consume an extra battery (up to 5-8% per hour when used actively) and may conflict with MIUI optimization. On the POCO X5 Pro, for example, the Stay Alive app sometimes resets settings after a reboot.

💡

If the shutter shutter application doesn’t work, check Settings → Apps → Permissions → Special Access → Battery Optimization and turn off optimization for that application.

5. Editing system files (for advanced)

This method is suitable only for users with an unlocked bootloader and installed TWRP. It allows you to change the system parameters responsible for screen speed, but requires caution - incorrect actions can lead to a "brick" of the device.

Instructions:

1. Download and install a root-enabled file manager (such as Root Explorer or Solid Explorer).
2. Cross the path. /system/build.prop and find the lines: ro.lge.proximity.delay=25 ro.config.notification_snooze=15000
3. Add a new line to the end of the file: ro.config.screen_off_timeout=-1
4. Save the changes, restart the phone.

⚠️ Note: Editing the build.prop file on HyperOS devices (such as Xiaomi 14) can lead to a cyclical reboot.Be sure to create a backup through the device before making changes. TWRP!

6.Alternative Solutions: Always On Display and Smart Scripts

If you want your screen to stay active only in certain situations (such as when navigating or listening to music), use the built-in MIUI features:

• 📱 Always On Display (AOD) — It displays time, notifications and other data on the screen that's off. → Screen. → Always on display. It only works on AMOLED-screens (e.g. Xiaomi 13 Ultra or Redmi) K60 Pro).
• 🎵 Smart Scenarios - in Settings → Special facilities → Smart scripts can create a rule that will turn off shutter speed when you run specific applications (like Google Maps or Spotify).
• 🔋 "In your pocket" mode - in Settings → Display. → In your pocket mode you can configure exceptions for certain actions (for example, the screen will not turn off when you connect the headphones).

The advantage of these methods is that they don’t affect battery life as much as shutting down shutter speeds completely. For example, AOD on the Xiaomi 13 Pro consumes only ~1% of battery per hour thanks to LTPO technology.

💡

For most users, the best solution is a combination of maximum shutter speed (30 minutes) + It's a smart script for specific applications, and it keeps the balance between convenience and autonomy.

7. Frequent problems and their solutions

When you turn off the screen shutter speed on Xiaomi, users experience typical errors. Here's how to fix them:

If none of the methods worked, check:

• 🔋 Is the battery saving mode activated (it resets shutter speed settings).
• 🛠️ Are there any third-party “optimizers” (e.g., “optimizers”) installed, DU Speed Booster, which can block changes.
• 📱 Is not the function of automatic switching off the screen when laying the phone down the screen (in Settings) → Display).
