Xiaomi's smartphone screen hides a lot more than you can see. Developer mode is a "secret room" for power users, where you can fine-tune performance, debug apps, or even unlock features that are not available in the standard MIUI. But where to look for it? If you first encounter this topic, you probably won't find this section in the usual settings menu - you need to activate it first.
In this article, we will not only show you how to turn on the developer mode on any Xiaomi device (from Redmi Note 12 to Xiaomi 14 Ultra), but also understand why you need it. You will learn how to use ADB to unlock the bootloader, speed up the animation of the system, enable debugging over USB or even change the screen resolution.
Where is the developer mode in Xiaomi: step-by-step activation
The default section for developers is hidden in MIUI, so that random users don't change critical system settings, and to open it, you need to do a simple, but not obvious, procedure:
- Open the Settings. โ The phone.
- Find the MIUI version and click on it 7 times in a row.
- After the seventh press, a notification will appear: โYou have become a developer!โ
- Return to the main Settings menu โ now there will be a new section โ For developers.
On some devices (such as the POCO X6 Pro or Redmi K70), the path may be slightly different:
- ๐น Settings โ System system โ The phone. โ Version. MIUI (7 taps).
- ๐น On tablets Xiaomi Pad 6: Settings โ About the tablet โ Version. MIUI.
- ๐น On Mi TVs. TV: Settings โ About the device โ Firmware version (press 7 times).
โ ๏ธ Note: If after 7 clicks the partition does not appear, check if the device has a stock launcher from a third party (for example, Nova Launcher.
What can be done in the developer mode: top-10 usefulness
Now that the partition is activated, let's figure out why it's needed. Here are the top 10 features that developers and advanced users alike will need:
- ๐ง Debugging by USB (USB Debugging โ a mandatory option to work with ADB, Unlocking the bootloader or firmware through Fastboot.
- โก Acceleration of animation: reducing window animation scale (Transition animation scale) to 0.5x The interface is noticeably faster.
- ๐ฑ Permission to install applications from unknown sources (even if it is prohibited in standard settings).
- ๐ Background processes: limiting the number of applications running in the background (Do not save actions or Maximum 4 of the process).
- ๐ฎ Emulation of additional screens โ useful for testing the adaptability of applications.
- ๐ก Turning on Wi-Fi Verbose Logging โ a detailed Wi-Fi log to diagnose network problems.
- ๐ Unlocking OEM (OEM Unlocking) โ the first step to unlock the bootloader and install custom firmware.
- ๐ฅ๏ธ Changing screen resolution (useful for testing or battery saving).
- ๐ Disable Absolute Volume โ fixes volume problems when connecting over Bluetooth.
- ๐ฒ Resetting App Access Rights โ If an app behaves incorrectly after an update.
Not all of these features are safe. For example, changing the screen resolution to a non-standard value can lead to artifacts or even overheating of the processor. And activating OEM Unlocking resets all the data on the device!
๐ก
Before changing critical parameters (for example, limiting background processes), check whether you are using applications that need constant work in the background (messengers, fitness trackers, banking applications).
How to use ADB and Fastboot: unlock the bootloader and not only
One of the main reasons for activating the developer mode is working with the tools ADB (Android Debug Bridge) and Fastboot.
- ๐ Unlock bootloader for custom firmware installation (LineageOS, Pixel Experience).
- ๐ฑ Install APK-files directly from the computer (adb install) app.apk).
- ๐ Backup of the system (adb backup) or restore data.
- ๐ ๏ธ Fix errors when the device does not boot (for example, after a failed update).
To get started, follow the following steps:
- Enable USB debugging in the โDevelopersโ section.
- Connect the smartphone to the computer and confirm the debugging permission on the device screen.
- Install Googleโs Platform Tools (includes adb and fastboot).
- Open the command line in the tool folder and check the connection: adb devices If the device appears in the list โ everything is ready to go.
โ ๏ธ Attention: Unlocking the bootloader on Xiaomi requires you to link your Mi Account to the device. Without this, after unlocking the phone can turn into a brick!

Hidden MIUI settings: what can be enabled through the developer mode
MIUI hides a lot of useful features that can only be activated through developer mode.
| Function | Where to turn it on | What do you need? |
|---|---|---|
| Force GPU Rendering | Developer settings โ Hardware acceleration โ Forced. GPU-rendering | Speeds up the rendering of the interface, but can increase battery consumption. |
| 4x MSAA | Developer Settings โ Hardware Acceleration โ 4x MSAA | Improves graphics in games, but greatly loads the processor. |
| Background Check | Developer settings โ Applications โ Background Process Check | Shows which applications consume resources in the background. |
| Show CPU Usage | Developer settings โ Monitor โ Show CPU load | It displays a schedule of the processor usage in real time. |
| Enable Freeform Windows | Developer Settings โ Opportunities โ Free Windows | Allows you to open applications in floating windows (like on a PC). |
Some of these features may conflict with optimizations. MIUI. For example, forced GPU-acceleration sometimes causes artifacts in applications, and 4x MSAA Reduces battery life by 15-20%.
What if you turn on all the hidden functions at the same time?
Dangerous settings: what not to touch in the developer mode
Not all of the parameters in the Developer section are harmless.
- ๐ Permanently lock the device (for example, the wrong firmware through Fastboot).
- ๐ต Disable the network (change modem settings or IMEI).
- ๐ Reduce battery life (forced activation) 5G non-compatible).
- ๐ฅ๏ธ Destroy the screen (incorrectly changing the resolution or refresh rate).
Here is a list of the most risky options that are best not to touch without a clear understanding:
- ๐จ Disable HW Overlays โ can cause graphical glitches.
- ๐จ Force RTL Layout โ mirrors the interface (useful only for localization testing).
- ๐จ Mock Locations โ Switching location may block some applications (e.g. banking).
- ๐จ USB Configuration โ Mode Change USB (for example MIDI) It may disrupt the connection of the PC.
- ๐จ Disable Bluetooth A2DP Hardware Offload โ Deteriorates the sound quality in Bluetooth headphones.
๐ก
If you're not sure what the setting is, it's best not to change it. Many of the settings in developer mode don't have a rollback and may require a factory reset.
Developer mode on other Xiaomi devices: smart watches, TVs, routers
Developer mode is not only available on smartphones, but in the Xiaomi Ecosystem, it can be activated on other devices:
๐บ Mi TVs TV redmi TV
To enable the Developer Mode:
- Go to Settings. โ About the device.
- Find the firmware version and click on it 7 times.
- Return to Settings โ Accounts and Security โ For Developers
Here's where you can turn it on. ADB over Wi-Fi (useful for installing third-party launchers) or change screen resolution (e.g. for testing) 4K-content).
โ Smart watches Mi Band and Xiaomi Watch
On wearables, the developer mode is activated via the Mi Fitness or Zepp Life app:
- Open the device profile in the application.
- Click on the icon. โ๏ธ (setting) โ About the programme.
