Xiaomi smartphone owners often face a situation where even powerful devices start to “brake” after a few months of use, the reason for this is not always hardware limitations – most often the problem lies in software optimization. MIUI This gives you access to dozens of settings that the manufacturer hides from the average user, and these settings allow you to manually control performance, animations, background processes, and even power consumption.
But there’s a catch: not all options are equally useful, and some can lead to overheating of the processor or accelerated battery discharge if configured incorrectly. In this article, we will only discuss those options that actually affect the speed of Xiaomi without sacrificing system stability. You will learn how to disable unnecessary animations, limit background processes, speed up interface rendering and even overclock the processor within safe values. MIUI 14/15 on models from the Redmi Note 10 Xiaomi 14 Ultra.
How to Enable Developer Mode on Xiaomi
Before optimizing MIUI, The activation procedure is the same for all modern Xiaomi smartphones, but the path may vary slightly depending on the firmware version.
Follow the step-by-step instructions:
- Open the Settings app.
- Go to About Phone (or About Device on some models).
- Find the MIUI version string and tap it 7 times in a row.
- After the notification appears, you become a developer! return to the main settings menu.
- Now a new item will appear in the list. → For developers.
If the item does not appear, check if it is hidden in the System submenu or Advanced Settings. Some firmware (for example, global versions for Europe) may need to link a Mi Account account.
💡
After activating the developer mode, do not rush to change all the settings in a row. USB) They can create security vulnerabilities if you don’t plan to use them for specific tasks.
Top.-5 speed-up MIUI
Not all of the options on the developer menu are equally useful, and we've selected the top 5 options that can deliver a noticeable performance boost without risk to the system.
- 🔄 Interface animations – reducing the transition time between screens.
- 📱 Background processes – limiting the number of applications running.
- 🖥️ rendering GPU — graphics acceleration.
- 🔋 Energy saving – balance between productivity and autonomy.
- 🚀 Optimization MIUI — disabling unnecessary system checks.
Let us look at each of them in more detail.
1. Disabling animations (speeding up the interface)
By default. MIUI It uses smooth animations to open applications, return to the home screen, and switch between tasks, and these effects are visually pleasing, but slow down the system, and it's a subjective 15-20 acceleration that you can get when you shut them down%.
How to turn it off:
- Go to Settings → Additional → For developers.
- Find the settings: The scale of the window animation → No animations The scale of transition animation → Without animation Duration of animation → Turn it off (if any)
Reboot your smartphone to apply the changes.
Turn off window animation|Turn off transition animation|Set the duration of the animation on 0.5x (If the complete shutdown is annoying)|Reset the device-->
⚠️ Note: On some models (POCO F5, Redmi K60) Disabling animations completely can cause the interface to twitch. 0.5x shutdown.
2. Limitation of background processes
MIUI It's known for aggressively managing background applications, but even that's sometimes not enough. You can manually limit the number of processes in a developer's menu, which will free up RAM and reduce the load on the processor.
Optimal values:
| Parameter | Recommended value | The effect |
|---|---|---|
| Limit of background processes | 2–3 process | Reduces RAM consumption, but can close frequently used applications |
| Not to keep up the action | On. | Kills applications immediately after closing (saves memory) |
| Limit background processes | Max. 4 trial. | Balance between productivity and multitasking |
⚠️ Note: If you use instant messengers (Telegram, WhatsApp) or notification apps (Gmail, Viber), too tight restriction of background processes can lead to message delay.
3. Accelerating rendering GPU
Graphics processor (GPU) In the developer menu, you can make the system use accelerated rendering, which is especially useful on weak smartphones (Redmi). 9A, POCO M3).
Activate the following options:
- 🎮 Accelerate work GPU → Includes (reduces scroll delays).
- 🖼️ Disable hardware overlays → Includes (Improving performance in games and heavy applications).
- 🔄 Forced processing GPU → Includes (forces all applications to use a graphics accelerator).
⚠️ Note: On some devices (Xiaomi) 12T, Redmi Note 11 Pro+) enforcement GPU It can cause artifacts in the interface (flickering, blurring). If you notice such effects, turn off the forced processing. GPU.
4. Optimization of energy consumption
Performance and autonomy are two sides of the same coin, and you can set the balance between them in the developer menu by selecting one of the profiles:
- ⚡ Performance – maximum speed, but fast battery discharge.
- ⚖️ Balanced – the best option for most users.
- 🔋 Energy saving – limits background processes and processor clock speed.
For most smartphones (POCO X5, Redmi Note 12 is recommended to use a balanced mode, and if necessary (games, video editing) temporarily switch to Performance.
Productivity|Balanced|Energy conservation|I don't know what it is.-->
5. Disabling optimization MIUI
MIUI The default is to include background optimization of the system, which allegedly “extends the life of the device.” In practice, this means that the system artificially restricts performance to reduce heat%.
How to turn it off:
- Go to Settings → Additional → For developers.
- Find the Optimization option MIUI (or MIUI Optimization in English-language firmware).
- Turn off the slider.
- Reset the device.
⚠️ Note: After disabling this option, some functions may stop working MIUI, for example:
- Automatic brightness control.
- Adaptive frequency of screen refresh.
- Some control gestures.
If you notice a problem, return the setting to its original state.
💡
Disabling optimization MIUI This is a performance boost, but it can disrupt Xiaomi's branded features. Use this setting only if you're ready for possible bugs.
Dangerous settings: what not to touch
Not all settings on the developer menu are safe. Some can lead to:
- 🔥 Overheating of the processor (if artificially accelerate the clock frequency).
- 📵 Loss of communication (when changing modem parameters).
- 🐌 Slowing down the system (if you incorrectly configure the task scheduler).
- 💥 Data loss (when debugging is enabled without backup).
Below is a list of options that you should not touch unless you are an expert:
| Parameter | Risk | Effects of consequences |
|---|---|---|
| USB debugging | ⚠️ Medium. | May allow malware to access the system |
| Unlocking the OEM | ❌ High-pitched | Simplifies hacking of the device, disables encryption |
| Compulsory regime GPU-rendering | ⚠️ Medium. | Can cause graphic artifacts and overheating |
| Change in the size of the journal buffer | ❌ High-pitched | It will lead to memory filling with logs and slowing down the system. |
If you still decide to experiment with these options, first create a backup through Settings. → System system → Backup or with Mi Cloud.
How to get it all back: Resetting the developer settings
If after the changes, the smartphone began to work unstable (for example, lags, overheating or rapid battery discharge began to appear), you can return all parameters to the factory settings.
Method 1: Manual reset
- Go to Settings → Additional → For developers.
- In the upper right corner, press three dots (⋮) and select Resetting Settings.
- Confirm the action.
Method 2: Complete reset (if the first method did not help)
- Open Settings → About the phone → Reset settings.
- Select Reset all settings (does not delete files, only returns settings to factory settings).
- Confirm the action and wait for the reboot.
⚠️ Note: If you have turned on the Unlock OEM or debugging. USB, After reset, these settings will be automatically disabled, which may affect the operation of some applications (for example, Magisk or Magisk). ADB-tool).
Optimization for specific Xiaomi models
Not all settings are equally effective across devices, and below are recommendations for Xiaomi’s popular lineups:
1. Budget smartphones (Redmi) 9/10/12, POCO M4/M5)
On weak processors (Snapdragon) 4xx/6xx, Helio Gxx) priority – freeing up RAM and disabling background processes.
- 🔄 Turn off all animations (Scope of window animation) = No animation).
- 📱 Limit background processes to 2-3.
- 🎮 Turn on Speed up the job. GPU, But do not activate the forced processing GPU (may cause lag).
- 🔋 Use Energy Saving Mode in Everyday Tasks.
2. Mid-segment (POCO X5/X6, Redmi Note 11/12, Xiaomi 12 Lite)
On smartphones with Snapdragon 7xx or Dimensity 9xx You can afford more aggressive settings:
- 🔄 Set the animations on 0.5x (A complete shutdown may look sharp).
- 📱 Limit background processes to 4.
- 🎮 Turn on Speed up the job. GPU and Disable hardware overlays.
- 🚀 Turn off optimization. MIUI (If you don’t use a branded feature like Super Wallpapers).
3. Flagships (Xiaomi) 13/14, POCO F5 Pro, Black Shark)
On top-end chipsets (Snapdragon) 8 Gen 2/3, Dimensity 9000+) It is possible to maximize potential:
- 🔄 Turn off animations completely or install 0.5x.
- 📱 Limit background processes to 5 (these models have enough RAM).
- 🎮 Enable all acceleration options GPU.
- 🚀 Turn off optimization. MIUI and set the performance mode.
- 🔥 Enable Forced Regime GPU-Rendering (but watch out for heating).
⚠️ Note: On flagships (Xiaomi 14 Ultra, Black Shark 6 Pro) forced use GPU It can cause overheating over long-term loads (games, video rendering) if the temperature is above 45.°C, turn off this option.
Myths about optimization MIUI: it doesn't work
There are dozens of Xiaomi’s “secret” acceleration tips on the internet, but many of them are either outdated or have no real effect.
❌ Myth 1: “Switching off Google’s services will speed up your smartphone»
Many users believe that Google Play Services and other Google system apps are slowing down the device.
- 📊 These services take less than 5% of CPU time in the background.
- ⚠️ Disabling them will disrupt the work of Play Market, Gmail, YouTube and other applications.
- ⚡ The only real effect is savings. ~100 MB of RAM, which is negligible on modern smartphones.
If you are critical to every megabyte of memory, use the Background Process Limit as described above.
❌ Myth 2: Cleaning the cache once a day speeds up work»
Cache is a temporary file that helps applications load faster.
- 🔄 It gives a short-term increase in free space, but slows down the re-launch of applications.
- 📉 Can cause lags when first downloading programs after cleaning.
- ⚠️ Nana MIUI Automatically clears the cache when memory is scarce – manual cleaning is usually not needed.
Exception: Clearing the cache makes sense if a particular app has started to “glue” (like Instagram or TikTok).
❌ Myth 3: “Switching off time synchronization will speed up your smartphone»
Some people suggest that you disable Autosynchronization of time in the settings, supposedly it reduces the load on the processor.
- ⏱️ Synchronization of time takes ~0.1% of the processor and occurs every few hours.
- ⚠️ Disabling will cause time failure after rebooting or exiting aircraft mode.
- 📡 It could disrupt the job. 2FA (Two-factor authentication in banking applications.
The only time it makes sense is if you never go online (like using your smartphone as a player).
❌ Myth 4: “Installing a custom core will speed up a smartphone»
Castomic nuclei (e.g. FrancoKernel or ElementalX) can improve performance, but:
- 🔧 Require an unlocked bootloader and root rights, which deprives of guarantees.
- ⚠️ Incorrect installation can lead to a brick (complete inoperability of the device).
- 📉 Performance gains on modern chipsets (Snapdragon 8 Gen 2) usually do not exceed 5-10%.
