Many Xiaomi, Redmi and POCO smartphone owners will sooner or later find themselves wanting more control over their device. The standard MIUI or HyperOS settings often hide the advanced features that are needed to deep customize, debug applications or install specific software.
Activating this mode will not instantly turn you into a professional programmer, but will give you access to critical functions of the system: you can control interface animations, track running processes, force hardware acceleration and, of course, connect your smartphone to your computer for data or firmware. This is the first step to fully understand how your Xiaomi works from the inside.
It is important to understand that interfering with system settings requires a certain amount of responsibility. Incorrect configuration of parameters can lead to unstable device operation or even data loss. However, if you follow clear instructions and understand the purpose of each function, you can significantly expand the functionality of your gadget without risk to the main system.
⚠️ Warning: Enabling Developer Mode removes some layers of system protection. Be careful when changing parameters that you don't know the value of, as this can affect OS stability.
Activate the Hidden Menu through Settings
The first and easiest way to access advanced features is through standard activation through the system interface. In the MIUI and HyperOS shells, this process is slightly different from pure Android, but remains logical enough. You don't need root rights or third-party software to perform this operation.
To start, you need to go to the basic settings of your smartphone, find a section that is usually called "About the phone" or "About the device." This is where you can find all the technical information about the model, the Android version and the build number. At the bottom of this list is a key element – the line “Version”. MIUI" (or "Version." OS" newer).
To activate hidden mode, you need to quickly tap this line seven times in a row. The system will start counting down, telling you how many clicks are left before activation. After the seventh click, you will see a pop-up notification that you have become a developer. If the phone has a password or pattern lock, the system may require you to enter it to confirm actions.
💡
If a seven-push doesn’t work, try making clicks at a faster pace, but not too often for the system to register each touch.
Once activated successfully, the main settings menu, usually in the "Advanced" section, will have a new "Developers" item, and that's where all the advanced management tools are concentrated, and the default USB debugging mode will be turned off, which is a security measure.
Configure debugging over USB and ADB
One of the main features of the developer menu is the ability to connect a smartphone to a computer for debugging. ADB (Android Debug Bridge) allows you to transfer commands directly to the operating system, bypassing the standard user interface. It is an indispensable tool for installing applications, uninstalling logs or unlocking the bootloader.
To start work, you need to find the item "Debugging by" in the developer menu USB" And you can activate it with a slider, and when you first connect to a computer, you'll see a request on your smartphone screen for permission to debug from that computer. RSA and press Allow, otherwise the computer will not be able to communicate with the device.
- 🔌 Connect your smartphone with the original cable to your PC, as the cables may not transmit data.
- 💻 Install Xiaomi drivers USB Driver on the computer to correctly determine the device.
- 🔐 Always check the connection confirmation pop-ups on your phone screen.
- 📱 Make sure that the operating mode USB installed in "File Transfer" (MTP), Not just "Charging".
Modern versions of Xiaomi shells have a feature called "Wi-Fi debugging" that allows you to connect to the device without a wire, which is especially convenient if the connector is not connected. USB It's damaged or occupied, and you have to turn on the appropriate switchboard in the developer menu, and then the system will give you the right switch. IP-port and address.
adb connect 192.168.1.105:5555Using wireless debugging requires that the smartphone and the computer be on the same local network. Data speeds may be lower than cable, but for most application management tasks, that's enough. Remember that open debugging ports on a public Wi-Fi network can carry security risks.
☑️ Checking debugging readiness
Animation and speed management
One of the most popular reasons for Xiaomi’s developer mode activation is the ability to speed up the visual part of the interface. Standard transition animations, window openings, and zoom can seem slow, especially on devices with less powerful hardware. Changing the scale of animation makes the interface more responsive.
In the developer menu, find the "Drawing" section, and you'll see three settings: "Window animation," "Jump animation," and "Animator duration." They're set to 1x by default. Changing that value to 0.5x will visually speed up the system by two times, creating the illusion of a more powerful processor.
It is not recommended to completely disable animation (value 0x), as the interface will become twitchy and devoid of visual connectivity between the screens. The optimal balance between speed and smoothness is precisely 0.5x. This is especially true for budget models of the Redmi series, where every millisecond of response matters.
| Animation parameter | Value 1x (Standard) | Value 0.5x (Optimum) | Value 0x (Without animation) |
|---|---|---|---|
| Response speed | Normal. | Fast. | Instant. |
| Visual perception | Smooth. | Dynamic. | Sharp. |
| GPU loading | Medium | Low. | Minimum |
| Recommendation | For the new flagships | Universally. | For weak devices |
In addition, the "process background" option is also available in this section, which allows you to limit the number of applications running in the background. Setting a limit can help free up RAM, but beware: an aggressive restriction can lead to restarting messengers and losing push notifications.
Working with running processes and memory
For advanced users, it's important to control how the system allocates resources. There's Process Statistics on the developer menu, which displays a list of all active applications, their running time and the amount of memory they consume, which helps identify voracious programs that are imperceptibly landing the battery.
The Do Not Activity feature is a powerful debugging tool, but it's dangerous for everyday use. If you turn it on, the system will destroy every process as soon as the user leaves the application, which allows you to test the recovery of the application, but in everyday life will lead to a constant reboot of programs.
Also worth paying attention to is the "Background Mode" option, which in some versions of MIUI allows you to forcefully limit background activity for all applications at once, which can be useful if you want to maximize battery life in a critical situation by sacrificing multitasking.
⚠️ Note: Forced termination of system processes through the developer menu can lead to a reboot of the interface (launcher) or temporary inoperability of the touch screen.
To analyze memory usage, you can include a display of running services, which will give you an idea of which system components Xiaomi is consuming resources right now, often it turns out that a significant portion of memory is occupied by Google services or shell system services.
Additional features and network settings
The developer menu hides a lot of settings related to network interfaces and bluetooth. For example, you can activate various Bluetooth codecs, such as aptX HD or LDAC, if your device and headphones support high audio quality, which allows you to significantly improve the audiophile performance when listening to music.
In the network section you can find settings DNS. Although the main settings are in the Wi-Fi menu, you can set static settings here. DNS for all interfaces or enable the use of DNS-over-TLS to enhance privacy. Wi-Fi/Mobile data" which helps keep the connection stable at a weak signal.
- 📡 Enabling Bluetooth logging HCI It allows you to record data packets for analyzing sound problems.
- 🌐 Minimum width adjustment (DPI) Changes the pixel density, making interface elements smaller or larger.
- 🔋 Real-time battery monitoring shows exact percentage charge and temperature.
- 📍 Location emulation allows you to test applications by changing your GPS-programmatic coordinates.
And the feature that's really worth mentioning is the "Touch Show" feature, which displays a white circle on the screen where you click, and it's useful for creating screencasts or training videos, so that viewers can see exactly where you're clicking on the display.

Safety and Return to Factory Settings
Using developer mode requires understanding the risks. Turning off Verify Apps over USB allows you to install modified versions of programs, but it opens the door to potential viruses. Always keep this option off unless you're testing your own software.
If the developer's settings change, the smartphone starts to behave unstable, the artifacts appear on the screen or the sound disappears, don't panic. Just turn off the main developer switch at the top of the menu, and it will return all parameters to factory values.
In extreme cases, if the changes have blocked access to the system, resetting will help. However, in 99% of cases, just deaktivirovat mode is enough. Remember that unlocking the bootloader is a separate procedure that requires binding the Mi Account and waiting for time, it does not turn on just by activating the developer menu.
⚠️ Note: Never turn on options related to OEM-Unlocking, unless you plan to flash the device, and accidental activation can make your phone vulnerable to theft.
Using the developer tools to make your Xiaomi from a consumer gadget to a powerful tool for work and experimentation, the key is to change only the parameters that you understand.
💡
The main principle of the developer menu: change only one parameter at a time and check the result so that in case of problems, you know exactly the cause of the failure.
