Many owners of Xiaomi, Redmi and POCO smartphones sooner or later encounter the mention of the so-called “working mode” – usually under this term hides the developer menu – the hidden section of the settings of the Android operating system, which provides access to advanced device management functions. In the standard state, this section is hidden from the eyes of the average user to prevent accidental changes in critical parameters that can disrupt the stability of the gadget.
Activating this mode opens the door to the user's world of fine-tuning interfaces, debugging applications and managing system processes. This is where the switches are located to speed up animations, change the behavior of the system when charging or enable debugging over USB to transfer data to the computer. Understanding what this tool is and how to use it is necessary for anyone who wants to get the most out of their Xiaomi.
However, it is worth noting that interfering with system settings requires caution. Incorrect configuration of some parameters can lead to unstable application performance or even cyclical device reboot. In this article, we will discuss in detail how to safely activate hidden functions, which options are really useful for everyday use, and which changes should be avoided without extreme necessity.
What is hidden under the term "working regime"
When users search for information about working mode, they often confuse several different concepts, primarily the developer menu, which is a standard part of Android, but has its own features in the shell of MIUI or HyperOS, this section is designed by Google and Xiaomi engineers to test applications and diagnose the system, and you can see detailed information about running processes, memory status and sensors.
The second aspect is the USB debugging functionality, which is a protocol that allows a computer to communicate with a smartphone at a deep level. Without this option, you can't install ADB drivers, flash your device through Fastboot, or use advanced tools to take screenshots and record screens from a computer. It can seem tricky for the average user, but it's these tools that help save locked phones.
⚠️ Attention: Including debugging by USB A lost or stolen phone can give attackers access to your data if the device is not protected by a strong password.
Also in Xiaomi’s context, there’s a lot of talk about “Game Turbo,” which optimizes CPU resources to run heavy applications. While technically a separate feature, it’s often associated with enhanced system capabilities. Understanding the difference between system debugging and game profiles will help you customize your smartphone to your needs without getting confused by the many settings.
How to activate hidden menus on MIUI and HyperOS
The process of enabling advanced settings on Xiaomi devices is standardized, but requires a certain sequence of actions. Unlike some other brands, you can't just find the switch in the basic settings here. You'll need to press the build number seven times to make the system believe that you are truly aware of your actions. It's a kind of protective mechanism against accidental activation.
To start, open the Settings app and go to About Phone, where you need to find the line MIUI Version or OS Version. That's the field you need to click on. It doesn't matter whether you have a Redmi Note 12, Xiaomi 13 or old POCO F1, the algorithm is the same for all current firmware versions. After a few clicks, a countdown pop-up will appear.
☑️ Activation algorithm
Once you see the "You've become a developer" notification, you can move to the next step, go back to the main settings menu and select "Additional" and the list that opens, usually at the bottom or in the middle, will have a new "Developers" section. Signing in may require confirmation of the screen unlock password or PIN-code SIM-Cards that are an additional security measure.
It's worth noting that some global versions of firmware may have slightly different paths, sometimes hiding inside the Advanced Settings category. If you can't find a point after activation, search by settings by entering the word "developer." The system will highlight the desired shortcut, saving time searching.
Key settings for optimizing the interface
One of the most popular reasons users activate this mode is the ability to speed up the visual perception of the smartphone. Android by default uses animations lasting 0.5 seconds to navigate between windows and menus, many consider this unnecessary and prefer to reduce response time, which makes the interface more “live” and faster.
In the developer menu, find a section that is related to drawing or animation. You are interested in three parameters: "Window animation", "Jump animation" and "Duration of animation." By default, they are all 1x or 0.5x. Changing these values to 0.5x or even "Animation is disabled" instantly changes the nature of the device's operation. The interface begins to "fly", disappears delays when folding applications.
| Parameter | Standard value | Recommended value | The effect |
|---|---|---|---|
| Window animation | 1x | 0.5x | Accelerated opening/closure of applications |
| Animation of transitions | 1x | 0.5x | Quick switching between screens |
| Duration of animation | 1x | 0.5x | General acceleration of visual effects |
In addition to animations, you can control font resolution and minimum screen width (DPI). Changing the DPI allows you to make interface elements smaller, which increases the amount of information that fits on the screen. This is especially true for owners of smartphones with large diagonals, such as the Xiaomi Mix or Redmi Note Pro. However, be careful: too high a DPI value can make text unreadable, and some buttons are unclickable.
What happens if you put animation 0?
Memory and background management
Xiaomi devices are known for their aggressive energy saving policies, which often kill background processes ahead of time. In the developer menu, you can find the Apps section, where the tools to control this behavior are hidden. The Background Process Limit option allows you to specify the number of applications that can remain active in memory after leaving them.
The default value here is Standard Limit, which means system control. If you change that to No Background, when you switch between applications, they will be constantly restarted. This can be useful for testing, but in everyday life, it will lead to increased battery consumption and slow start of programs. On the other hand, increasing the limit can help messengers and navigators work more steadily.
It also has a Do Not Stay Activity feature, which will destroy the process as soon as the user leaves the application, a radical measure that should only be used in cases of extreme memory shortage or when debugging your own applications, and for normal tasks, it is better to leave standard settings or choose "No more than 4 processes".
⚠️ Attention: Forced restriction of background processes may cause you to stop receiving notifications from WhatsApp, Telegram or email before the app opens.
Another important tool is Running Services, which is where you can see which system services are running right now and how much RAM they're using, and it's a great way to diagnose why the phone is slowing down, and if you see a process with a vague name that takes hundreds of megabytes, you can try stopping it, even though the system might start it again.
Debugging over USB and interaction with PC
USB Debugging is a cornerstone for advanced users, allowing a computer to send commands to your phone, install apps bypassing the Play Market Store, remove system software, and make full backups of data. Without this switch, most Android tools simply won’t see your device.
When the first cable connection after debugging activation on the smartphone screen, a confirmation request will appear RSA-The computer shows the digital fingerprint, and you have to press "Allow," which ensures that only trusted computers have access to debugging. If you connect your phone to a public charging station at the airport, never confirm this request as it could be an attempt to steal data.
adb devices

Xiaomi also needs to set "Mode" USB-debugging (security settings)" which allows you to control your phone from your computer with a mouse and keyboard, which is convenient for presentations or remote control.
💡
Use the original debugging cable. Cheap charging-only cables have no data lines, and the computer won't be able to connect to the phone no matter how much you configure the menu.
Additional features and network settings
The developer menu isn't just about system settings, it's about networking and multimedia, like the "Show Touch" feature that displays a white dot on the screen at the touch of a finger, which is incredibly handy when you're creating screencasts, training videos, or just checking the touchscreen for dead zones.
For Xiaomi routers and those who like to experiment with Wi-Fi, the Network section is interesting, where you can force support for high-quality Bluetooth codecs (aptX HD, LDAC) if your headphones support it, and the “Always enable mobile data transfer” option is available, which leaves 4G/5G active even when connected to Wi-Fi, which can be useful for a quick switch if the router loses the Internet.
And there's a special focus on Adaptive Brightness, and in some versions of MIUI, you can find additional sliders on the developer menu to calibrate the light sensor, and if your phone dims your screen too much indoors or blinds you at night, you can try to find compensation, but these settings are often hidden or depend on the particular display model.
- 📡 Mobile network is always active – speeds up switching between Wi-Fi and mobile Internet, but increases battery consumption.
- 🎧 Bluetooth codecs – allow you to choose a priority codec for transmitting sound to wireless headphones.
- 📍 Exact location – Settings for Wi-Fi and Bluetooth scanning even when off to improve geolocation.
And remember, the log section, where you can turn on logging, which is useful if you're running into a bug and you want to send a report to the developers, but persistent logging can take up space in memory and slightly load the processor, so it's best to keep those functions off in normal mode.
💡
The developer menu is a powerful tool, but 90 percent of users just need to scale up the animation, and the rest of the functions require understanding the implications of enabling them.
