Xiaomi smartphones are among the most flexible in terms of customization among Android devices, but even experienced users do not always know what is under the hood. MIUI There are dozens of additional features that are not available in the standard interface, and they can only be activated through the developer mode, a special settings section designed to test, debug and fine-tune the system.
Enabling this mode opens up opportunities such as forced activation. USB-debugging ADB, Changing the animation of the interface, unlocking the CPU frequency, or even imitating a secondary display, but not all features are safe for inexperienced users. For example, incorrect settings in the Developer Options section can lead to overheating of the device, accelerated battery discharge, or even soft-brick (software โbricking").
In this article, we will discuss in detail how to activate the developer mode on any Xiaomi smartphone (including Redmi, POCO and Mi), what features are hidden there, and how to avoid typical errors. MIUI 12โ14 and HyperOS (2026).
Why do I need a developer mode on Xiaomi?
Many users mistakenly believe that the developer mode is only for programmers or those who are engaged in firmware modification, in fact, even a regular user can use it to:
- ๐ง Accelerating the smartphone โ disabling unnecessary animations and background processes.
- ๐ฑ Simulations of other devices โ for example, to test applications in tablet mode.
- ๐ Battery Control โ Forced fast charging shutdown to extend battery life.
- ๐ฅ๏ธ Connections to PC - activation USB-debugging ADB, Scrcpy or Fastboot.
- ๐ก Network settings โ Manual control of connection types (2G/3G/4G/5G) or enable Mobile Hotspot without limitation.
But there's a downside: some parameters can disrupt the stability of the system, such as forced activation. GPU-acceleration for all applications often results in graphic artifacts, and the change in the value of the animation duration to the 0x Makes the interface less responsive.
The developer mode is also required for:
- ๐ Unlock the bootloader before installing custom firmware.
- ๐ธ Manual camera testing (e.g. for shooting in format) RAW).
- ๐ฎ Optimize performance in games through Force settings GPU Rendering.
โ ๏ธ Note: On devices with HyperOS (new shell from Xiaomi), the path to developer mode may be different. MIUI In the settings, check the section About the phone โ HyperOS version.

What can I do in the developer mode?
Some options can harm the device if you change them without understanding the consequences.
- โ Change Max. background processes โ a restriction to 1-2 processes will lead to constant reboots of applications.
- โ Turn on Do not turn off the screen โ this will quickly drain the battery and can cause burn-in (burnout) AMOLED-screen.
- โ Change. GPU-rendering for all applications โ many programs are not optimized for this, which will cause graphical glitches.
- โ Activate Demonstration Mode is a test mode that shows false data (e.g., a full battery at 1%).
- โ Turn on Debugging. USB On a permanent basis, this creates a vulnerability to malware.
Also dangerous:
- ๐ซ Change the settings of Wi-Fi scanning โ this can disrupt the operation of wireless networks.
- ๐ซ Enable background check for all applications โ this increases the load on the processor.
