How to turn off the automatic screen switch on Xiaomi Poco F3 while listening to voice messages

Xiaomi Poco screen F3 Automatically shuts down after 30 to 60 seconds of inactivity – standard energy saving feature MIUI. But what to do if you listen to long voice messages on Telegram, WhatsApp or VK, Is the screen going out, interrupting playback control? This problem is especially relevant for users who are used to controlling the pause, rewind or volume directly from the lock screen.

In this article, we will discuss all working ways to turn off the screen on Poco. F3 during listening to audio - from standard settings MIUI to the hidden functions through ADB We also explain why some methods may not work on your firmware and how to fix it.

Let me warn you right away, there's no one-size-fits-all solution. MIUI (for example MIUI 14 and HyperOS are different paths in the menu, the type of content played (voice messages vs. music tracks) and even the installed applications. F3 with different firmware - in the article only proven options.

If you need a quick solution, go to the "Keep Screen On" section of the developer settings. ADB Automation through Tasker.

Why the screen goes out during audio playback

At Xiaomi Poco. F3 Three mechanisms are responsible for turning off the screen:

1. Screen Sleep Timer – Standard Settings in Settings → Display. → Sleep screen that extinguishes the screen at a given interval (15 seconds to 30 minutes).
2. Optimizing the battery MIUI — aggressive energy saving, which suspends background processes, including audio playback through some applications.
3. Android Policy – Starting with Android 10, the forcedly system suspends screen activity if there is no explicit interaction (touching, gestures).

The problem is compounded by the fact that voice messages in instant messengers (such as Telegram) are not perceived by the system as “music”, but as “notification”, so standard settings such as “Do not turn off the screen while playing music” do not apply to them.

Another nuance: on Poco F3 s AMOLED-If you plan to use the methods in this article regularly, we recommend that you reduce the brightness to 30-50% or include a dark topic.

Method 1: Screen and battery settings in MIUI

Let’s start with the simplest – standard tools. MIUI. These methods do not require root or PC connection rights, but do not work in all scenarios.

Step 1. Increase the screen sleep timer

Open the Settings. → Display. → Sleep screen and select the maximum value - 30 minutes or Never (if available). F3 The “Never” option is hidden – it can be activated through the developer settings.

Step 2: Turn off battery optimization for instant messengers

Go to Settings. → Annexes → Manage applications, find your messenger (such as Telegram) and select:

• 🔋 Without limitation in the section "Energy consumption".
• 🚫 Turn off the "Out-Start" option (if enabled).
• 📱 Allow background activity.

Step 3: Enable "Previous Replay"

In the same application settings, find the "Advanced" section and activate:

• 🎵 Reproduction of sound in the background.
• 🔔 Show notifications (important for controlling from the lock screen).

Important: MIUI 14 and HyperOS, the path to power consumption settings has changed – now it’s in Settings → Battery → Selection of applications (cog icon in upper right corner).

Method 2: Developer settings (without root)

V MIUI There are hidden options that allow you to keep the screen on during active processes.

How to Enable Developer Mode on Poco F3:

1. Open the Settings. → The phone.
2. Find the line "Version" MIUI" And tap it 7 times in a row.
3. Enter a password/pattern lock if required.
4. Return to the main settings menu and a new section for developers will appear.

Key settings to turn off the screen sleep:

• 📱 Don't turn off the screen -- turn on this option. It causes the screen to remain active while the device is connected to charging.
• ⚡ Stay active while charging – similar to the previous point, but only works while charging.
• 🔄 Debugging by USB — will be necessary for methods of ADB (see next section).

Please note: the “Do not turn off screen” option may not be available on some Poco firmware F3. In this case, try an alternative method through ADB.

💡

If the "Developers" section disappeared after the update MIUI, Repeat the procedure of inclusion (7 taps according to the firmware version).

Method 3: ADB commands (for power users)

If standard settings don’t help, you can manually turn off your sleep timer via Android Debug Bridge (ADB). This method requires connecting your phone to your PC, but does not need root rights.

What you need:

• 🖥️ Computer with installed ADB Tools.
• 📱 Included Debugging by USB Poco F3 (see previous section).
• 🔌 USB-cable (preferably original).

Step-by-step:

1. Get Poco on. F3 to the PC and confirm the permission to debug on the phone.
2. Open the command prompt (cmd on Windows or Terminal on macOS/Linux) and type: adb devices Make sure your device appears in the list.
3. Use the command to turn off the screen: adb shell settings put global stay_on_while_plugged_in 3 3 — The screen does not go out during charging or from the battery. 1 — only when charged USB. 0 — shutdown.

Reboot the phone.

How to return the standard settings:

adb shell settings put global stay_on_while_plugged_in 0

This method works on most Poco firmware F3, But it may reset after the update. MIUI. Also note that the constant burning of the screen increases battery consumption by 15-25%.

Method 4: Third-party applications for screen control

If you don't want to mess with ADB or settings MIUI, We tested 5 popular apps, and the best results were found in Keep Screen On and Caffeine.

Top.-3 POCO F3:

How to set up Keep Screen On:

1. Install the app from Google Play.
2. Open it and grant permission for Special Opportunities.
3. Select in the settings: 🔄 Mode of work: “When active". ⏱️ Timeout: Never". 📱 Apps: Add your messenger (e.g. Telegram).

Activate the utility through the tile in the notification panel before listening.

⚠️ Note: FakeTouch applications can cause false positives in games or banking applications. Do not use them simultaneously with security systems (for example, Google Pay).

Method 5: Automation with Tasker (for advanced)

If you’re willing to take the time to set up, Tasker will allow you to create a fully automatic solution: the screen will only turn on when you play voice messages and go out the rest of the time.

What you need:

• 📱 Installed by Tasker (paid application).
• 🔧 AutoInput plugin (to simulate touch).

Instructions for creating a profile:

1. Open Tasker and create a new profile (+ → Annex).
2. Select your messenger (for example, Telegram).
3. Add condition: Condition → Multimedia. → Reproduced.
4. Create a task with actions: 1. Display → Set timeout: 3600 seconds (1 hour) 2. → Touch simulation (coordinates: 500, 500, duration: 100 ms) 3. Repeat every 30 seconds
5. Save the profile and activate it.

This is the most flexible method, but it requires testing, for example, WhatsApp may need a different trigger (not “Replayed”, but “Notice with buttons”).

⚠️ Warning: Too frequent imitation of touch (more often 1 time in 20 seconds) can lead to a screen lock by a security system MIUI. The optimal interval is 30-40 seconds.

Typical problems and their solutions

Even after all the methods are used, the Poco screen F3 It can go out. Here are the most common causes and ways to fix them:

Problem 1: Settings are reset after the MIUI update

• 🔄 Solution: Repeat the settings ADB-Enable the Developer Mode or Re-enable the Developer Mode.
• 📱 Prevention: Turn off automatic firmware updates in Settings → The phone. → Updating the system.

Problem 2: The screen doesn’t go out, but the battery goes down in 2-3 hours

• 🔋 Solution: Reduce brightness to 30% and turn on a dark theme.
• ⚡ Alternative: Use the method with ADB, but install stay_on_while_plugged_in 1 (only when charged).

Problem 3: Methods work, but not with voice messages

• 🎵 Reason: Messengers play voice messages not as "music" but as "notification".
• 🛠️ Solution: Use Tasker with notification trigger (see previous section).

Problem 4: After application ADB-The screen does not go out even in your pocket.

• 📵 Solution: Return the setting stay_on_while_plugged_in 0 and use Tasker with the condition "Screen is on".

Critical: On some Poco firmware F3 (for example, MIUI 13.0.6) team stay_on_while_plugged_in In this case, only Tasker or third-party applications will help.

Safety warnings and recommendations

Keeping the screen on is not only a convenience, it's also a risk.

1. Burnout risk AMOLED-screen

Poco F3 fitted AMOLED-a matrix that is exposed to burn-in (constant display of static elements leads to "shadow" on the screen) to minimize the risk:

• 🌑 Use dark theme and wallpaper without bright static elements.
• 🔄 Change the location of the control panels (for example, move the player to different parts of the screen).
• ⏱️ Limit the time of continuous screen operation (maximum 1-2 hours).

2. Increased battery consumption

According to our tests, the constant burning of the screen on Poco F3 Increases battery consumption by 20 to 30 percent:

• 🔌 Use methods that only work when charging (stay_on_while_plugged_in 1).
• 📉 Reduce brightness to a minimum and turn on adaptive brightness.

3. Conflicts with applications

Some banking applications (e.g. SberBank Online) block your work when you detect FakeTouch or Tasker.

• 🚫 Turn off automation before entering the bank.
• 🔒 Use Android Guest Mode to Isolate Conflicting Apps.

⚠️ Attention: On Poco F3 Unlocked bootloader or root rights some methods (for example, ADB-commands) may not work due to modified firmware. In this case, try Magisk modules like "Screen Off Timeout".

💡

The safest method is to use a Tasker with a playback trigger, which does not affect the battery in the background and does not cause burn-in if the screen goes out when inactivity is not used.
