Xiaomi’s current smartphones, which run MIUI shells or the new HyperOS, have a huge hidden potential that is not available to the average user by default. Its engineers leave many tools to fine-tune the system, debug applications and manage CPU resources, but they are closed to avoid accidental changes by inexperienced owners.
Activating this hidden partition opens the door to a world of deep customization, allowing you to speed up animations, prohibit background processes to save charge or, conversely, improve performance in games. It is important to understand that interfering with system settings requires caution, since incorrectly changing some parameters can lead to unstable operation of the device. However, if you want to gain full control of your gadget, studying this section is a must.
In this article, we will discuss in detail how to activate a hidden menu, which parameters should be changed first of all to improve the responsiveness of the interface, and analyze the popular myths associated with debugging over USB. You will learn how to properly use the developer tools on the Redmi Note, Xiaomi Mi and POCO series to squeeze the maximum out of the smartphone without the need to obtain root rights.
Why you need a developer mode and what it gives
The developer section is not just a random switch set, but a powerful toolkit for testing applications and optimizing the Android operating system. It was originally created by Google engineers to debug the code of running applications in real time, but enthusiasts quickly found it more widespread use in everyday use, with the help of which you can change the behavior of the system, which with standard tools of the settings menu can not be changed.
One key feature is managing interface animations. Standard window transitions in MIUI can seem lengthy, which visually slows down the smartphone. By changing the scale of animation, you can make the interface sharper and faster, which is especially true for models with high refresh rate screens. USB debugging is another important component that allows you to transfer data between your computer and phone at a low level, which is necessary for installing drivers, flashing or using advanced control tools.
This section also hides settings related to CPU and RAM, so you can limit the number of background processes to free up resources for heavy play, or you can turn on the display of the current CPU load in real time. System services become transparent to the user, allowing you to see which applications consume energy in the background, even if they are not displayed in the standard list of running tasks.
⚠️ Warning: Changes in parameters associated with hardware acceleration or graphics rendering (e.g., “Force” 4x MSAA»), This can cause the device to overheat and the battery to run out quickly, and only use these features when you need them and understand the risks.
It is worth noting that the functionality may vary slightly depending on the firmware version. Global ROMs may have a wider feature list than China ROM, where some experimental features may be blocked or renamed.
The process of enabling developer mode on Xiaomi smartphones is standardized and does not require a connection to a computer or the use of third-party software. All actions are performed directly in the interface of settings of your device. The main thing is to be careful when counting clicks, since the system protects this partition from accidental activation.
First, you need to get to the main settings menu. To do this, open the Settings app (cog icon) on your desktop or in the notification curtain. Next, look for the About phone section. Depending on the version of the MIUI or HyperOS shell, it can be at the top of the list or hidden in the Additional submenus. This is where all the technical information about your device is contained.
Inside the About Phone section, you need to find the MIUI Version line (or OS Version in new firmware). The key is to quickly tap that line 7-10 times in a row. You don't need to pause between taps, the rhythm should be uniform. After a few clicks, the system will start to output pop-up notifications, counting how much more you have to press before activating the mode.
Once you reach the right number of clicks, the screen will see a message “You’re a developer!”. After that, a new “Developers” option will appear in the main settings menu, usually in the “Additional” category or immediately in the list of main settings (depending on the interface version).
Configuring debugging over USB and working with PC
One of the most popular features of the hidden menu is “Debugging by the USB». This option allows the computer to access the phone’s debugging data, which is necessary to work with the command line. ADB (Without enabling this feature, many advanced smartphone management software from a PC will simply not see your device or will have limited access.
To activate this function, go to the “Developers” menu and find the “Debug by” switch. USB». When it is first activated, the system will issue a warning about potential security risks, as this mode gives a high level of data access. You will need to confirm the action by clicking “OK”, and then, when connecting to a new computer, confirm the debugging permission in the pop-up window on the smartphone screen, checking RSA-key.
In addition to basic debugging, you can also set up settings for emulating location, selecting a display app (if an external monitor is connected), and configuring USB by default. You can set your phone to always charge, transfer files (MTP) or work as a network card (RNDIS) when you connect the cable.
adb devices
adb shell pm list packages
To work with the command line on your computer, you will need to install Xiaomi USB Driver drivers and the SDK Platform-Tools platform. After connecting the cable and enabling debugging, entering the adb device command in the terminal should display the serial number of your device, which will confirm the successful connection. If the device number is displayed unauthorized, then you have not confirmed the permission on the phone screen.
What to do if your computer can’t see your phone?
Make sure you use the original cable that can transmit data, not just charge. Check if the driver is installed in Windows Device Manager. USB-port to motherboard ports (back of the system unit), as the ports of the front panel may not give enough voltage or have poor contact. ADB Optimization of the interface and acceleration of the system The most noticeable effect for the average user from the activation of the developer mode is the ability to speed up the visual part of the interface. Android uses 0.5 second animations to open windows, close apps, and switch between menus by default. By reducing this, you’ll make your smartphone experience much faster and more responsive, creating the illusion of a more powerful processor. In the "Developers" section, find the "Drawing" block. You're interested in three options: "Window animation," "Jump animation" and "Animator duration." By default, they are set to "1x" or "Animation is enabled." Change each of these values to "0.5x." If you want to completely remove animation, select "No animation," but this can make the interface too sharp and unusual. Another useful tool is to adjust background processes. If you have a device with a small amount of RAM (for example, 3 or 4 GB), you can limit the number of processes to the browser, or more often it will not use the "This is used in the process" and "It is more often used in the browser." 🚀 Font scaling: allows you to change the density DPI, making interface elements larger or smaller without changing the system font. ⚡ Strict Mode: Visualizes application errors by highlighting the screen red for long operations in the main stream (useful for developers). 🎨 Show touch: displays white dots at the touching points of the finger to the screen, convenient for creating screencasts and instructions. To make it easier for you to navigate through a variety of settings, we have prepared a summary table of the most useful features of the developer mode. Here are the names of the parameters, their impact on the system and recommended values for everyday use. Parameter Location Recommended value System Impact Windows Animation Drawing 0.5x Accelerates the opening of applications Transition animation Drawing 0.5x Makes the windows fold faster than the Application 2-4 process Limits the background processes Save RAM Do not turn off the screen Debugging off the screen Screen goes out when simple (savings) Show touch Input At will Visualization of clicks on the screen Please note that some parameters may be called differently depending on the localization of the firmware. In Chinese versions of China ROM, the names may differ, but the default value is not allowed ("If the system is not to be replaced by the default value. " Despite the ease of activation, users often face a situation where the developer menu disappears by itself after a reboot or system update. This is the usual security behavior of Android and MIUI: if you haven’t used the developer’s features for a certain time or after a major update, the system will automatically deactivate this section to minimize the risks of vulnerabilities. In this case, you should not panic or look for complex recovery methods. Just repeat the activation procedure: again click on the firmware version in the About Phone section. All your previous settings within the developer menu will likely reset to the factory values, so I have to reset them. ⚠️ Warning: If the phone starts to behave unstable after the developer mode is turned on (spontaneous reboots, freezes), immediately turn off the Developer Switch at the top of the menu, this will turn off all the settings you have changed and return the system to standard. Another common problem is that you can't connect your phone to your computer to debug, and it's often because of drivers or cable. ADB Interface. Also check if the antivirus or firewall is blocking the connection of the debugging device. USB in the developer menu (item "Resetting settings" USB»). 📊 Why do you need a developer mode?Speed up interface animation:To debug applications:To connect ADB:Just for the sake of interest: I don't know, I want to try it. 💡Developer mode is a powerful tool, but it's not a panacea; it doesn't add any physical new RAM or CPU power, it just optimizes the use of existing resources. The use of the developer mode carries certain risks that every user should be aware of. USB Makes the device more vulnerable when connected to public charging stations or other computers. An attacker with physical access to the phone and debugging enabled can access the file system or install malware. So never leave USB debugging on permanently unless you're using it right now. Once you're done with ADB or logging, it's better to turn off the switch. This simple rule will significantly improve the security of your personal data. Also be careful about features that change the GPU, as they can lead to image artifacts or instability in games. In conclusion, the developer mode on Xiaomi is a great way to better understand how your smartphone works and customize it to your needs. Proper use of animations and process control can prolong the life of old models and make using new ones even more enjoyable - the main thing is to act on the rollout and remember any moment of the rollback? No, the inclusion of the developer mode and changing the settings inside it is not a violation of warranty obligations. The warranty is lost only in the event of physical damage to the device, moisture or installation of unofficial firmware (unlocking the bootloader), which is a separate procedure that goes beyond simply turning on the developer menu. Can you delete the system applications through the developer mode? You can't directly delete the system applications through the developer menu. USB, You can use the commands. ADB on a computer (e.g. adb shell pm uninstall) --user 0 The name of the packet to remove the system software without root permissions, which requires caution, because removing critical components can lead to a "brick" of the device? Android automatically disables developer mode after major operating system updates or resets. This is a security measure. You need to re-click 7 on the build number in the About section to activate it again. Does developer mode affect the battery? The developer mode itself does not consume the battery. However, features included inside it, such as "Do not turn off the screen," "Show touch" or "Force 4x MSAA," can significantly increase power consumption. If you notice a fast discharge, check the active toggles in this section. How does the developer mode switch from the main menu to the developer completely switch from the top of the device to the device?
