How to enable Xiaomi Redmi without the power button: The complete guide

When a Xiaomi or Redmi smartphone is completely discharged or turned off and the power button fails, it can cause panic in any owner. It would seem that the device has turned into a useless piece of plastic and glass, but modern technology allows you to bypass a physical defect. In most cases, the problem lies not in the complete failure of the system, but in the sticking of a mechanical switch or a software failure that blocks a standard start.

Before you bring your device to the service center, it’s worth trying software-based resuscitation techniques that are often more effective than mechanical intervention. There are several proven ways to run the Android operating system on Mi and Poco devices using only a charger, a computer, or special combinations of actions with a screen interface. It’s important to understand that each method has its own nuances and is suitable for different battery states.

In this guide, we will take a look at all the options available to launch a smartphone, from simple charging manipulations to using the Fastboot engineering menu. You will learn how to activate the dual tap function, use a PC connection, and even how to temporarily replace the physical button with a software emulator. Follow the instructions carefully to bring the device back to life without additional financial costs.

Using a charger and PC to start

The easiest and safest way to try to turn on a phone with a broken button is to use a power source. When you connect the cable to a USB Type-C or Micro-USB port, the power controller receives a signal that there is a voltage. Many Xiaomi models with a MIUI or HyperOS shell implement an automatic turn on function when connecting to the network, even if the device was completely turned off.

However, if the phone just shows the battery icon and doesn't boot any further, you can try to wake it up via a connection to the computer. Connect the smartphone to a working PC or laptop using the original cable. At the time of connection, the motherboard gets a pulse that in some cases initiates the system to boot, bypassing the need to press the physical key. This method is especially effective if the battery has been deeply discharged.

⚠️ Warning: If the screen catches fire but the phone is stuck on the logo or zipper icon, don't disconnect the cable immediately. 10-15 minutes, as the system requires a minimum charge to start, which could be exhausted at the time of the attempt to turn on.

It's also worth trying a combination of charging and clamping volume buttons. While the phone is connected to the network, try pressing Volume Up or Volume Down. On some firmware, this action force the device into recovery or bootloader mode, where you can choose to restart.

Launching through Fastboot and Recovery mode

If a standard network connection fails, you need to use low-level modes of operation of the device. Fastboot mode is a special diagnostic protocol that allows you to interact with the phone at the bootloader level. To enter this mode on a phone that is turned off, you usually need to press the volume button and connect the cable to the computer.

Once you get into the Fastboot menu (the image of a rabbit fixing an android appears on the screen, or the word FASTBOOT), you have the ability to control power through program commands. Connect your phone to your PC, install ADB drivers and platform tools. Open the command line, you can send a signal to reboot, which is equivalent to pressing the power button.

Enter the following command to reboot to normal mode:

fastboot reboot

An alternative way is to enter Recovery mode. To do this, when the phone is turned off, press the volume button and connect the power cable at the same time. If a menu with several points appears on the screen in English or Chinese, use the volume buttons for navigation. Select Reboot and confirm the action if you need to press the power button - try to quickly press it several times, sometimes the contact is, but it is bad.

It is important to note that working with the bootloader requires caution: improper actions in this mode can lead to the need to flash the device, although a simple reboot command is safe for user data.

Software activation through Assistant and settings

If you manage to start the phone in some way (for example, the button sometimes works or you used the charging method), your first priority should be to configure alternative control methods. In the MIUI shell, there is a built-in "Assistant" feature that adds a floating button to the screen with basic functions, including locking and turning off the screen.

To activate, go to Settings → Advanced Settings → Assistant and turn on the switch. A translucent button will appear on the screen, which opens the action menu when you press it. Although this button can not always turn on a completely turned off phone, it allows you to control the screen and avoid situations when the device goes out and there is nothing to wake it up.

In addition, in the screen lock settings, you should activate the function "Double touch to turn on." This will allow you to wake the smartphone with a light tap on the display, completely eliminating the need to use a physical power button in the everyday scenario. → Lock screen → Double touch to turn on/off screen.

Another useful tool is to install third-party power button emulator apps from the Google Play store. Programs like Button Mapper or Volume Button Screen Off allow you to reassign volume button functions. You can set the phone so that prolonged clampdown on the volume button turns on the screen or performs other system actions.

ADB Team Method for Advanced Users

For those who are not afraid to work with the command line and have basic Android administration skills, there is a powerful ADB (Android Debug Bridge) debugging tool, which only works if the phone has previously enabled the Developer Menu and activated the USB Debugging. If these conditions are met, you can control the device remotely from your computer.

Connect your smartphone to your PC and enter a command in the terminal to reboot:

adb reboot

This command forcibly restarts the device, which is equivalent to turning it off and on. If the phone is in sleep mode, the adb shell input keyevent 26 simulates pressing the power button, including the screen, one of the most reliable software methods, without requiring physical impact on the body.

Use of the ADB-It gives you complete control over the system, but requires prior preparation. If you often encounter button problems, it makes sense to keep a customized platform on your computer. SDK, to quickly reanimate the gadget at a critical moment.

Hardware solutions and interim measures

When software is exhausted, you have to use physical pressure, and if the button doesn't work because of contamination or oxidation of the contacts, you can try to clean the area around the key carefully, use a soft toothbrush and a small amount of isopropyl alcohol, gently cleaning the gap between the button and the body, which can remove dirt that interferes with the contact.

Another radical, but sometimes working, method is to tap the back of your smartphone in the vicinity of the power button, which in older Redmi models could temporarily restore the contact of the plume, but excessive mechanical stress can damage the battery or unplug the display, so act extremely carefully and without fanaticism.

⚠️ Warning: Do not attempt to disassemble your phone or close the contacts of the power button with tweezers unless you have experience with electronics.A short circuit can disable the power controller, and repairs will cost significantly more.

If you get a button inside the case, you can try putting a thin piece of plastic or tape underneath it to level it up, which is a temporary solution that allows you to press the button before you visit the service, and the main thing is to ensure that you have at least the minimum key stroke necessary to close the chain.

💡

Use a magnetic charging cable to minimize wear on the USB port, as frequent connections to turn on the phone can sway the connector.

Prevention and setting up of the inclusion schedule

To avoid a situation where you need to turn your phone on manually, set up automatic on and off schedule. This feature is built into MIUI and allows the device to start itself at a given time. Go to Settings → Battery → Schedule on/off and set a convenient time, for example, 7:00 a.m.

This setup is useful not only when a broken button is broken, but also to extend the battery life.The phone will automatically reboot once a day, which cleans the RAM and prevents the accumulation of system debris. This is especially true for low-end Redmi models, which can run slower over time.

Also worth paying attention to is energy saving settings: Make sure Ultra-Energy Saving mode does not block important system processes that could help restore operation. Sometimes turning off aggressive battery optimization for system applications solves the problem of spontaneous shutdowns.

💡

Automatic turn on on schedule is the best insurance against breakage of the power button, allowing you to use the phone without physical intervention during the day.
