Mobile games are becoming increasingly hardware demanding, and even powerful flagships sometimes can’t handle the smoothness of the picture. Smartphone owners Xiaomi, Redmi and POCO often face a situation where in dynamic scenes the number of frames per second drops sharply, causing jerks and lags, this is especially noticeable in popular shooters and “battle royale”, where every fraction of a second affects the result of the match.
Fortunately, MIUI and its successors provide a wealth of tools to fine-tune performance. Disabling background processes, activating game modes, and using the developer menu correctly, make the most of the hardware available. In this article, we’ll look at proven techniques to help stabilize your device in heavy applications.
Built-in MIUI optimization tools
The first thing to start with is to use the system’s regular capabilities. Xiaomi has built a Game Turbo mechanism into its shell that redistributes CPU and RAM resources in favor of running a game, and ignoring this tool deprives the user of a significant portion of the performance available out of the box.
To activate, you need to open the Security app and find the corresponding section in the bottom menu, add all games used to the list, and activate the acceleration function. The system automatically clears the memory before starting and blocks incoming notifications so as not to interrupt the gameplay.
- 🚀 Network Acceleration: Prioritizing Traffic Allocation for Play.
- 🔋 Performance mode: removing the restrictions from the processor during the game.
- 📉 Decreasing graphics quality: Automatic optimization of rendering resolution.
It is also important to check the screen settings in the Settings → Screen section. Make sure the refresh rate is set to the maximum value (90 Hz, 120 Hz or 144 Hz) supported by your Xiaomi or Redmi model. If you are using Auto, the phone can save energy at the expense of smoothness, which is unacceptable for gaming.
⚠️ Attention: Constant maximum performance performance leads to accelerated battery wear and heat generation. Use these settings only during gaming sessions.
Secrets of the developer menu for gamers
The hidden developer menu contains options that directly affect how the system handles graphical commands, and you can get there by clicking on the MIUI version several times in the About Phone section. Once you see the option in the settings, you will have access to dozens of hidden controls.
Most useful for increasing FPS It's a zoom parameter, but for games, it's more important to set up rendering. HW-imposition (disable) HW overlays, and activate it. GPU handle all interface elements, which can reduce the load on the CPU and remove micro-fries.
☑️ Settings for activation
Another critical setting is limiting background processes, and in the developer menu, find the background limit and set the value to "No more than 2" or "No background processes," which will free up RAM, which greedy applications like social media often waste.
| Parameter | Recommended value | Impact on FPS |
|---|---|---|
| Banned HW-lay-up | Included. | Reduces the load on the CPU |
| Background processes | Max. 2 process. | Frees RAM. |
| Windows animations | 0.5x or Retraction. | Accelerates system response |
| 4x MSAA | Off. (for the weak) | Reduces the load on the GPU |
⚠️ Warning: Do not change the values in the Drrawings or Hardware accelerated rendering section unless you are sure of your actions. Incorrect settings can lead to artifacts on the screen or reboot the device.
Temperature and trottling management
One of the main reasons for the fall in FPS is trottling, a forced reduction in the frequency of the processor when overheated. Xiaomi and POCO smartphones have built-in temperature sensors that protect the device, but often do it too aggressively, starting to “strangle” performance at 40-45 degrees.
To delay the onset of trottling, you need to provide a good heat sink. Remove the protective case during long gaming sessions, as silicone and plastic work as a thermal insulator. Ideally, you can use external coolers for smartphones that are attached to the back cover.
Also avoid gaming when charging the device. The charging process itself generates heat, and when combined with the load from the game, the temperature can reach critical values in a matter of minutes. If you need to play, use Flight mode or turn off the mobile network, as finding the signal also heats the modem.
The Truth About Phone Refrigerators
Cleaning up memory and background services
Lack of free RAM is a classic problem with Redmi’s budget and mid-budget models: When RAM is overflowing, the system begins to actively use internal storage as virtual memory, which happens hundreds of times slower and causes lags.
Before starting a heavy game, it is recommended to manually close all applications. Don't rely only on the "Clear" button in the curtain, go to the menu of running tasks and swipe everything unnecessary. It is also useful to periodically reboot your smartphone to reset the cache of system services.
- 🗑️ Garbage Removal: Use a built-in cleaner to remove temporary files.
- 📱 Uninstall: Remove apps you don’t use, especially those that hang in the background.
- 🔄 Update: Make sure the game and system are updated to the latest versions.
Special attention should be paid to the autoload of applications. In the settings, find the Applications → Permissions → Autorun and leave only messengers and alarms on. The rest of the programs do not need to start with the phone and consume resources.
💡
Regularly cleaning up RAM and banning auto-runs of unnecessary applications can improve FPS stability by 10-15% on devices with 4GB of RAM or less.
Graphics settings inside games
Users often tend to set maximum graphics settings, forgetting that mobile processors are not designed to work at their limits. Decreased textures and shadows in the game settings (PUBG, Call of Duty, Genshin Impact) often give a greater increase in FPS than any system tweaks.
First, reduce the settings Shadow and Anti-aliasing. These settings are the most loaded GPU. Rendering resolution can also be reduced: on a 6-inch smartphone screen, the difference between 720p and 1080p is not as noticeable as the difference between 30 and 60 frames.
If the game has a High Frame Rate or 90 FPS mode, be sure to activate it, even if it means reducing the graphics to "Smooth" or "Low".
⚠️ Attention: Use of third-party mods, GFX-Tools or scripts to unlock 90 FPS In games where this is not officially provided, it can lead to the blocking of the account by the game developers.
Advanced Methods: ADB and Debugging
For advanced users who are not afraid of the command line, there is the possibility of fine-tuning through ADB (Android Debug Bridge), which allows you to remove system applications (bloatware), which cannot be removed in the usual way, and change the hidden parameters of the system.
To connect, you need to enable debugging over USB in the developer menu and install drivers on the PC. After connecting through the command line, you can execute a command to disable heavy MIUI services that consume resources in the background.
adb shell pm disable-user --user 0 com.miui.analyticsThis command disables system analytics, which constantly collects data about device usage, as you can do with advertising services and other built-in Xiaomi applications that are not necessary for the basic functions.
💡
Before using ADB, make sure to make a complete backup of the data. Mistaked removal of system components can lead to a cyclical restart (bootloop).
