The developer mode on Xiaomi Redmi smartphones is a hidden control panel that gives access to dozens of additional settings. From debugging over USB to changing the interface animations, these features are not available in the standard MIUI menu, but can significantly improve the operation of the device. However, many users do not risk activating this mode for fear of disrupting the stability of the system or losing the warranty.
In fact, turning on the developer mode on Redmi is a completely safe procedure, if you follow the proven instructions. In this article, we will discuss not only the standard way to activate through settings, but also alternative methods for cases where the Suddenly developer menu disappears after the update, and you will learn which features should be included first and which should be abandoned so as not to reduce the performance of the phone.
Important: All the instructions in this article are valid for MIUI 14 and HyperOS (2026), but they are also valid for earlier versions of the firmware. If your Redmi runs on an older version of Android (below 10), some menu items may differ, as we will also mention separately.
Why you need a developer mode on Xiaomi Redmi
Xiaomi hides modes for power users by default to prevent accidental changes that could lead to crashes. But for those who want to get the most out of their Redmi, this tool becomes indispensable.
- 🔧 Debugging by USB: Without it, it is impossible to connect the phone to ADB for firmware, unlocking the bootloader or data recovery.
- ⚡ Accelerating animation: Reducing the transition time between screens makes the interface visually faster (especially relevant for budget models Redmi Note). 8/9).
- 📡 Manual Network Configuration: Choosing a Mobile Network Type (2G/3G/4G/5G), Forced VoLTE activation or disabling automatic switching.
- 🔄 App cache reset: Cleaning the data of a particular application without deleting it (useful to save space).
- 🛡️ Controlling background processes: limiting the activity of applications that “eat” battery power.
In addition, in developer mode, you can enable click visualization (useful for creating training videos), secondary display simulation (for testing applications), or even change the screen resolution - the latter is relevant for games where frame rates are important.
⚠️ Note: Some developer mode settings may conflict with optimizations MIUI. For example, compulsory inclusion GPU-Rendering for all applications increases the workload on the processor and reduces battery life by 15-20%.
Standard way: how to enable the developer mode through settings
This is the easiest and safest method that works on all Xiaomi Redmi models, from the Redmi 4X to the Redmi Note 13 Pro+. The instructions are universal for MIUI and HyperOS, but the paths to the menu can vary slightly depending on the firmware version.
Algorithm of action:
- Open the Settings app (the gear icon on the home screen).
- Scroll down and select About Phone (Device Information may be called on HyperOS).
- Find the MIUI Version line (or build number on older versions) and tap it 7 times in a row.
- After 3-4 taps, a pop-up notification will appear: “You’re almost there!”. Keep pressing until you see the message “You’re a developer!”
- Return to the main Settings menu – there will be a new section Additional → Developer options (or just for developers).
If nothing happens after 7 taps, check:
- 🔄 Have you confused the line version? MIUI with the device model or Android version - tapping is necessary according to the firmware version.
- 🔒 Make sure there are no restrictions on the phone (such as parental controls or corporate policies).
- 📱 On some models (Redmi) K50, Redmi Note 12 Pro Reboot Required After Activation.
Make sure the battery is charged > 30%|Shut down. VPN (It can block system notifications)|Check the vacant space (needs to be checked) ≥ 500MB)|Remember the password from the Mi Account (required to unlock the bootloader)-->
On HyperOS (a new firmware from Xiaomi, released in 2026), the path to the developer menu can look like this: Settings → Additional → Special Features → Developer Parameters. If you do not find a section, search by settings (the magnifying glass icon in the upper right corner).
Alternative methods for incorporating the developer mode
Sometimes the standard method doesn't work: for example, after resetting the settings or updating the firmware, the developer menu disappears, and taps on the MIUI version do not work, in which case one of the alternative methods will help.
Method 1: Through ADB (if USB-The debugging has already been included)
If you previously activated the developer mode but it disappeared after the update, you can return it using the ADB command:
adb shell settings put global development_settings_enabled 1
adb shell am broadcast -a com.android.settings.action.DEVELOPMENT_SETTINGSThis command is forced to turn on the developer menu and open it.
- 🖥️ Computer with installed ADB-drivers for Xiaomi.
- 🔌 USB-cable (preferably original).
- 🔓 Debugging authorization USB (if it has been given before).
⚠️ Note: If you have never turned on the developer mode, this method will not work – first you need to activate it in the standard way (via taps according to the version). MIUI).
Method 2: Engineering menu (for advanced users)
On some Redmi models (e.g. Redmi 9A or Redmi 8), you can turn on the developer mode via the engineering menu.
- Open the Phone app.
- Enter the code: ##4636###.
- In the menu that appears, select Phone Information.
- Scroll down and click Developer Settings (if the string is inactive, the method is not suitable for your model).
This method does not work on all devices and can vary depending on the version of MIUI. On HyperOS, the engineering menu is often blocked.

Top.-5 Useful features in developer mode for Xiaomi Redmi
Once you activate the developer mode, you'll see over 50 settings, and we've selected the most useful ones that will really improve Redmi's performance without disrupting the stability of the system.
| Function | Why do you need it? | Adjustment recommendations |
|---|---|---|
| USB debugging | Connecting to a PC for firmware, backup or data recovery | Turn on, but never connect your phone to other people’s computers – this is a risk of data leakage |
| Window animation | Accelerating transitions between screens | Set the value 0.5x or turn off completely (no animation) |
| Keep the screen down. | The screen remains on when charging. | Useful for watching video or navigation, but shortens the life of the matrix |
| Background processes | Limiting the number of working applications | For 4-6 GB of RAM, set a maximum of 4 process |
| GPU-acceleration | Forced use of a graphics processor | Not recommended for all applications – it can cause overheating |
Special attention should be paid to the setting Aggressive destruction of background processes. On Redmi with 8+ GB of RAM, it can be turned off to improve multitasking, but on budget models (Redmi 10A, Redmi 9C), this will lead to slowdowns.
💡
If after changing the settings, the phone began to slow down, return everything to its original state using the developer reset button at the bottom of the menu.
What can go wrong: risks and how to avoid them
Developer mode is a powerful tool, but uncontrolled changes can lead to problems, and here are the most common mistakes and their consequences:
- 🔥 Overheating of the device: occurs when forced on GPU-Acceleration for all applications or processor overclocking.
- 🔋 Fast battery drain: settings like Don’t turn off the screen or a constantly active Bluetooth connection are to blame.
- 🐢 Slowing down the interface: often caused by the animations being turned off on weak devices (Redmi) 7A, Redmi 8).
- 🚫 Blocking Mi Account: If you enable Unblocking OEM And try to flash the phone with unofficial firmware, Xiaomi can block the device.
To minimize the risks:
- Before changing any setting, remember its original value (or take a picture of the screen).
- Do not turn on functions that you do not understand (for example, turn off the absolute volume level).
- After experimenting with settings, restart your phone – some changes only take effect after the reboot.
⚠️ Attention: setting Unlocking OEM (OEM Unlocking) allows you to unlock the bootloader, but automatically resets all the data on the phone when you first connect to the Mi Unlock Tool!
What if the phone stopped turning on after the changes?
How to turn off the developer mode on Xiaomi Redmi
If you no longer need advanced settings or want to return the phone to factory status (e.g., before selling), you can deactivate the developer mode.
- Go to Settings → Additional → Developer settings.
- In the upper right corner, press the switch (it should turn grey).
- Confirm the disconnection in the window that appears.
After that, the Developer section will disappear from the settings menu, but there is a caveat: some versions of MIUI (especially 12-13) reset all related settings (for example, debugging over USB or limiting background processes) after disabling the developer mode.
If the switch in the developer menu is inactive (locked), try:
- 🔄 Reboot the phone.
- 🔧 Reset application settings: Settings → Annexes → Application management → Settings (three points) → Resetting application settings.
- 📱 Make reset to factory settings (extreme case).
💡
Turning off the developer mode does not remove changes you made earlier (like accelerated animations) and to get it back to normal, you need to manually reset each setting.
Developer mode on Redmi with custom firmware
If your Xiaomi Redmi runs on unofficial firmware (like LineageOS, Pixel Experience or Xiaomi.EU), the process of enabling developer mode may be different.
- 🔧 On Xiaomi.EU, the developer menu is already unlocked by default – just go to Settings → System system → Additionally. → Developer parameters.
- 📱 On LineageOS and others AOSP-Firmware path to menu: Settings → System system → For developers.
- ⚠️ On some custom firmware there is no check on tapas - the developer menu appears immediately after installation.
- 🔓 Unlocking the loader (OEM Unlocking) on custom firmware can work unstable - check compatibility on the forum before firmware 4PDA.
Important: on custom firmware, some developer mode features may be missing or work differently, such as setting up 4G Enablement may not work due to a modified core.
If you plan to flash Redmi custom firmware, unlock the bootloader first through the official Mi Unlock Tool (even if the developer mode is already on), otherwise you risk getting a brick.
