How to make the screen does not go out on the phone Xiaomi Redmi 7

Owning a modern smartphone involves constant interaction with the device, but situations when the display goes out at the most inopportune moment can be very annoying. Especially often this problem is faced by users of budget models such as Xiaomi Redmi 7, where the power saving settings are set by default to maximize charge savings. When you read a long article, watch a video without sound or use the navigator, a sudden switching off of the backlight causes you to constantly touch the screen or side button, which distracts from the main process.

The solution lies in deep customization of the MIUI system, which controls the behavior of the display. Standard settings often do not take into account individual use cases, so the user needs to adjust the time intervals and disable functions that interfere with comfortable work. In this article, we will discuss all available ways to prevent automatic screen cancelling, from basic timer settings to hidden developer functions.

Before you make any changes, you should understand that the constant glow of the matrix directly affects battery consumption. However, if your goal is maximum comfort or specific use of the gadget as a dashboard, these sacrifices are justified. Let's look Step-by-step, how to adapt the behavior of your Redmi 7 to your needs.

Basic setting of the timer transition to sleep mode

The most obvious and first step that every Android smartphone owner needs to take is to change the waiting time before locking. In the MIUI shell installed on Redmi 7, this setting is not hidden deep, but has its own display features in different versions of the firmware. By default, the system often offers very short intervals, such as 15 or 30 seconds, which is inconvenient to read.

To change these values, you need to go to the settings menu. Find the partition that controls the look and lock. This is where the slider or time-spaced list is located. Choose the maximum value available, which is usually 5 or 10 minutes, and this will create a comfortable pause during which the screen will remain active without your intervention.

⚠️ Attention: Maximum latency significantly increases your energy consumption. If you forget to put your phone in your pocket, your battery may run out faster than usual.

Sometimes users are faced with a situation where the selected time is not saved or reset after a reboot, this may be due to the operation of system optimizers or conflict of third-party applications, in which case it is recommended to check for system updates or reset the display settings to factory, and then repeat the procedure for setting the timer again.

To access these settings, follow the following steps:

• 📱 Open the Settings app on the main screen.
• 🔒 Go to Lock Screen or Screen and Brightness.
• ⏱️ Find the Sleep Mode and select the right time.
• ✅ Check the changes by locking and unlocking the device.

Importantly, in some versions of MIUI, the path to settings may be slightly different. If you don't find the "Sleep Mode" item in the specified location, search for the settings by typing the keyword "sleeping" or "timer." This is a versatile method for navigating through Xiaomi's complex menu structure.

Use of the “Do Not Turn Off Screen” Mode for Developers

For those cases where even 10 minutes of waiting is not enough and requires the display to burn constantly while charging or running specific applications, there is a hidden feature in the developer menu called “Keep screen on” and ignores the standard lock timer while the device is connected to a power source or the debugger is running.

To activate this mode on Redmi 7, you first need to unlock access to advanced settings, this is done by repeatedly clicking on the build number in the About section. Once the developer mode is activated, a new item will appear in the main settings menu, where the desired feature is hidden, which is a powerful tool for stationary use of the smartphone.

Settings -> About Phone -> 7 times press "Version MIUI"

Once you turn on the developer mode, find a debugging item on the list, and it will have a switch that prevents you from going to sleep when charging, which is the perfect solution if you use your phone as a navigator in your car or as a clock on your desk.

• 🔧 Go to Settings -> Advanced settings.
• 👨‍💻 Select the item for developers.
• 🔌 Find the option Do not turn off the screen and activate it.
• 🔋 Connect the charger to check the function.

⚠️ Attention: Constant operation of the display at maximum brightness can lead to overheating of the matrix and the effect of "burnout" of pixels on the surface of the screen. AMOLED-The screens are used in Redmi 7. IPS, The risk is minimal, but heating the body is possible.

It's worth remembering that this function only works when the charger is connected, and if you turn off the cable, the screen will start to go out according to the standard timer you set up earlier, which is a protective mechanism that prevents the battery from completely draining in the forgotten state.

Setup of the proximity and lock sensor in the pocket

A common cause of sudden screen quenching is not a timer, but a false alarm of the proximity sensor. In the Redmi 7, this sensor is located at the top of the case, next to the speaker. If you hold the phone in a certain way, covering the top face with your finger, or if there is a poor quality protective film on the screen, the system may think that the phone is held to the ear, and extinguish the display.

MIUI also has a "Block in your pocket" feature that uses the same sensor to prevent accidental taps. If this function is not working properly, the screen can go out immediately after unlocking or during a conversation, and disabling or calibrating these features often solves the problem of spontaneous tapping.

To check and adjust the sensor, follow the following steps:

• 📞 Open the phone application (calling).
• ⚙️ Click on three dots in the corner and select Settings.
• 🚫 Find the Lock item in your pocket and turn it off for the test.
• 🧪 To check the sensor, enter the code ##6484## in the call.

In the engineering menu that opens by code, you can do a detailed diagnostic. Choose the Proximity sensor test. Cover the top of the screen with your hand, the indicator should change color or value. If there is no reaction, it may be a hardware problem or you need to calibrate through the same engineering menu.

It's also worth checking if you have a thick protective film covering the sensor area, and sometimes even a small crack in the glass at the top can distort the sensor readings, making the system think the phone is in the dark or in your pocket.

Brightness and autobrightness management

Another reason why the screen may seem like it's "extinct" is that it automatically reduces the brightness to a minimum. The MIUI system aggressively saves energy, and if the light sensor is contaminated or closed, it can transmit incorrect data about the low light around, resulting in the matrix's backlighting so that the image becomes barely visible.

To rule out this factor, try turning off automatic brightness control, which will allow you to manually set a comfortable level of glow that will not change arbitrarily, just unlock the screen, swipe the notification curtain down and press the sun icon, switching it to manual mode.

Using a dark theme can also visually change the perception of brightness.Redmi 7 with its IPS-screen black color is still illuminated, but the general background of the interface becomes darker, which reduces the load on the eyes and creates the illusion of less brightness at the same level of backlight.

💡

If the light sensor is not working properly, try to wipe the top of the screen with a soft cloth. Fat spots often prevent the sensor from correctly assessing the surrounding light situation.

Remember, manual brightness control requires your attention, and when you go out in the bright sun, you have to add brightness yourself, otherwise the content will become unreadable, which is a trade-off between the stability of the screen and the convenience of changing lighting conditions.

The effect of energy saving mode on the display

MIUI is known for its aggressive energy saving policy, where when the battery is below a certain level (usually 20% or 10%), the savings mode automatically turns on, in which the system forcibly reduces the time before turning off the screen, limits background activity and reduces brightness, ignoring your previous settings.

If you notice that the screen is going out faster than usual, check the battery indicator in the upper right corner. If it's on yellow or orange, then saving mode is active.

For food management:

• 🔋 Go to the Safety app (green icon with lightning).
• ⚡ Select the Battery item in the top menu.
• 🛑 Click on Active Mode (e.g., Balanced or Saving) and change it.
• 📉 Avoid Ultra or Maximum Savings for everyday use.

⚠️ Note: In maximum saving mode, some applications may not work in the background, and notifications may come with a delay, as the system limits network activity.

It's also worth checking the settings of specific applications. MIUI has a Battery and Performance feature for each application installed. If your reader or navigator has a "No Network" or "Limit Background Activity" restriction, this can indirectly affect the behavior of the screen when working with this software.

Third-party applications for screen locking

If standard tools are not enough, specialized applications from the Google Play store come to the rescue, allowing you to create profiles in which the screen never goes out or only goes out when certain conditions are met (for example, when the phone is horizontal), this is especially convenient for scenarios that are difficult to predict with standard settings.

A popular solution is the app "Caffeine" or its analogues, which adds a quick button to the notification curtain that forces the screen to be turned on. Press the button, the screen is on. Press again, the regular timer works. It's a flexible tool that does not require root rights.

Advantages of using third-party utilities:

• ⏱️ Exact control of activity time (up to 24 hours).
• 📱 Possibility of customization for specific applications.
• 🚀 Quick access through the notification curtain.
• 🛡️ Lack of deep interference with system files.

But be careful when choosing these programs, many of which may contain ads or require extra permissions, and choose high-rated and high-downloaded apps to keep your data safe.

💡

Third-party apps are the best choice for temporarily turning off the timer, whereas system settings are better suited for permanent use.

Installing this app makes your Redmi 7 a more versatile tool, so you can watch recipes in the kitchen without worrying that the screen will go out in 30 seconds, or use your phone as a digital photo frame while it's charging.
