Xiaomi’s current smartphones, which run MIUI or HyperOS shells, hide many powerful tools from the eyes of the average user. These hidden capabilities, known as developer parameters, give access to fine-tuning, process management and diagnostics, and many device owners look for them to enable USB debugging to install ADB drivers or simply speed up the interface by changing the scale of animation.
By default, this menu section is securely hidden to avoid accidental changes in critical settings that can affect the stability of the gadget. If you are wondering where to find the developer settings on Xiaomi, then you are ready to move to the next level of interaction with the device. To activate the partition, you need to quickly click on the build number in the About menu seven times, after which the system unlocks access to the engineering menu.
In this article, we will take a detailed look at the entire activation path, look at the basic features available after turning on, and discuss which settings are really useful for everyday use, and which are better not to touch without absolutely needing.
Why to activate the hidden menu and what it gives
The main purpose of the development section is to provide tools for testing applications and debugging code, but for advanced users it is a storehouse of useful features that allow you to optimize the performance of a smartphone, for example, changing the animation ratio of windows and transitions visually speeds up the system, making the response to touch more instantaneous.
And then you have settings that are related to power consumption and background processes, and you can limit the number of background processes to save battery power, or you can turn on the actual CPU load display in real time, and this data is useful for identifying the heavy applications that are slowing down Redmi or Poco.
It's important to understand that changing certain parameters can cause some applications or systems to be unstable, so you don't have to change values that you don't know what they're doing, but you have to focus on secure settings, like scaling the interface or managing notifications.

Before changing any settings in the developer menu, take a screenshot of the initial values – this will help you quickly return everything as it was if something goes wrong.
Step-by-step instruction: how to turn on the developer mode
The process of activating hidden menus on Xiaomi devices is standardized, but may vary slightly depending on the version of the MIUI shell or HyperOS. First, go to the main settings menu of your device.
Inside this section, you'll need to find a line called the MIUI Version (or OS Version). This is the field you need to run a series of quick clicks on. Make 7-10 quick clicks in a row. If you did everything right, a pop-up notice will appear: "You're a developer!"
☑️ Activation of the developer mode
After successful activation, the system may request the entry of a screen unlock password or pin code. SIM-This is a security measure that prevents accidental access to system functions. Now a new section has appeared on the menu, but it still needs to be found.
Where is the menu after activation?
Once you've been granted developer status, the new section won't appear on the home settings screen. It's hidden in the Additional section. Depending on the firmware version, the path may look like Settings → Additional → Developers. Newer versions of HyperOS have the same layout logic, but the visual design may have changed.
If you can't find "More," try searching by settings, type "developer" or "developer" into the search box, and the system will redirect you to the menu, which is the fastest way to get to the desired section without going through long searches.
Inside, you'll see a long list of different options, grouped into debugging, networking, input, drawing, and hardware acceleration categories. The first few lines usually contain an activation switch (which should already be on) and USB debugging settings.
Key settings to optimize the smartphone
Among the dozens of options available, there are a few that really affect the user experience, and first of all, you should pay attention to the Drawing section, which is the Windows Animation Scale, Transition Animation Scale, and Animation Duration, which are set to 1x by default.
Changing those values to 0.5x or even “No animation” makes the interface more responsive. The smartphone starts to “fly” as the system spends less time rendering visuals when opening and closing applications, and this is especially true for models with 60Hz screens or budget devices.
Another useful feature is not to turn off the screen when charging, which is convenient if you use your phone as a navigator or a desktop clock while charging, and the "Show Touch" option, which visualizes the pressing points on the screen, which is useful when creating training videos, is also worth mentioning.
| Parameter | Recommended value | The effect |
|---|---|---|
| The scale of window animation | 0.5x | Accelerating window opening |
| Scale of transition animation | 0.5x | Quick switching between screens |
| Duration of animation | 0.5x | Reduction of waiting time |
| Background processes | No more than 4. | Savings in RAM |
Don't change all your settings to maximum values right away. Try setting 0.5x and using your phone for a couple of days. If the interface gets too twitchy, put it back. Comfort is a subjective concept.

Debugging with USB and working with ADB
One of the main reasons users are looking for developer options is to enable USB Debugging.This mode allows the computer to communicate with the phone at the deep system level using the Android Debug Bridge (ADB) protocol.
The debugging mode is necessary for:
- 📱 Install applications directly from your computer without using stores.
- 💻 Removing system debris and undeleteable Xiaomi apps.
- 🔧 Resetting the unlock password (in some cases) or restoring access.
- 📸 Creating full data backups with third-party software.
⚠️ Attention: When you first connect the phone with debugging enabled to the new computer, a request for debugging confirmation will appear on the smartphone screen. RSA-key and press "Allow", otherwise the computer will not see the device in mode ADB.
To activate, look for the USB Debugging menu and put the switch into active position. The system will warn you about the risks associated with data transfer. Confirm the action. Now, when you connect the cable to the PC, the phone will go into data transfer mode, not just charging.
Security and Possible Risks of Changing Settings
Despite the wide range of features, the developer menu requires caution: Changing settings associated with network protocols or Bluetooth drivers can cause the smartphone to stop seeing headphones or Wi-Fi routers. In some cases, a complete reset may be required.
OEM unlocking is particularly dangerous, allowing the bootloader to be unlocked, which is necessary for custom firmware installation, but on Xiaomi devices it can also result in Mi Account blocking or loss of warranty if the official unlocking procedures are not followed.
If you notice that the phone is not behaving properly after your experiments, don't panic. There's a reset button at the top of the developer menu. By pressing it, you'll return all settings to their original state, as if you've just activated the mode.
💡
The main rule of security: do not change the settings in the "Network" and "Bluetooth" sections, if you do not know exactly what a particular parameter is responsible for, so as not to lose communication with the outside world.
