How to Speed Up Games on Xiaomi: A Complete Guide to Optimization

Mobile gaming on Xiaomi and Redmi devices has become incredibly popular due to its excellent price-performance ratio. However, even powerful flagships can over time face frame drops (FPS) or sudden micro-freezes at critical moments of a match, often due to the features of the MIUI or HyperOS shell, which consumes significant system resources in the background.

To make the most of your smartphone, it’s not enough to just close your apps. You need to make a comprehensive setup, disable unnecessary visuals, and adjust game modes correctly. In this article, we’ll look at proven methods to help stabilize the CPU and graphics accelerator.

Before we start taking any drastic measures, we need to understand that temperature trottling is a natural defense mechanism that reduces the CPU frequencies when it is heated, and our goal is to optimize the system so that it works more efficiently before critical temperatures, ensuring smooth gameplay.

Activation and fine-tuning of Game Turbo

The first and most obvious step for any Xiaomi owner is to properly configure the built-in gaming center. Unlike just running apps, Game Turbo redistributes system resources, prioritizing gameplay over background tasks. You can access the menu through the Security app or swipe from the corner of the screen while playing.

Inside the Game Turbo settings menu, you need to activate the performance mode, which will force the system to keep the CPU frequencies at a high level, ignoring standard energy saving algorithms, but be careful: this mode significantly increases power consumption and heat the device body.

Also available in this section is the Network Acceleration feature, which prioritizes game traffic if you use mobile internet or Wi-Fi. For online shooters, this is a critical parameter that reduces ping and the likelihood of connection breaks.

• 🚀 Activate Performance Mode in Game Turbo settings for maximum FPS.
• 📶 Enable Network Acceleration to stabilize connection in online games.
• 🔔 Set up a “floating window” to respond to messages without leaving the game.
• 🎚 Adjust the sensitivity of the touchscreen in the profile of each specific game.

💡

Each game's profile can be customized to respond to the touchscreen separately. For shooters (PUBG, COD Mobile), set the value "Ultra High", and for strategies - "Standard" or "Low" to avoid accidental clicks.

Management of animations and system interface

The MIUI and HyperOS shells are famous for their beautiful yet heavy animations. They create smoothness in everyday use, but in games can consume precious GPU resources. Disabling or shortening animations is one of the most effective ways to instantly feel the increase in responsiveness of the interface.

To access the advanced animation settings, you'll need to activate the developer menu, and this is done by tapping the build number five times in the About section, and then you'll have access to the hidden settings in the Advanced Settings menu.

⚠️ Note: Do not turn off all animations completely (value) 0x), Because it can cause some interface elements to be incorrectly displayed or visual artifacts to be displayed when applications are folded — 0.5x.

In the developer menu, find the items “Scale of window animation”, “Scale of transition animation” and “Duration of animator”. Set 0.5x for all three parameters. This will make the transitions between the menus instantaneous, which is especially noticeable in heavy games with long level loads.

Also, you should disable Memory Extension if you have less than 6 GB of RAM. Using a portion of UFS’s RAM as RAM can slow down the system, as the read speed of the drive is lower than the speed of real RAM.

Memory Cleansing and Background Process Management

Free RAM is key to a stable framerate. Android can manage memory efficiently, but on Xiaomi, aggressive background policies sometimes interfere. Before starting a heavy game, it is recommended to manually close all unused applications through the menu of recent tasks.

There's also a hidden feature in the developer menu called Background Process Limit, which by setting a 2-4 process limit, you ensure that the system will forcefully kill the extra apps that try to run in the background while playing, which frees up resources for the game engine.

Remember to regularly clean the cache of system applications and messengers. Garbage files can take up gigabytes of space, which is especially critical for eMMC drives, where write speeds drop when you fill more than 80% of the volume. Always leave at least 10-15% free space on the internal disk.

For advanced users, it is possible to disable system services that are not necessary for playing through ADB (Android Debug Bridge), which requires a connection to a computer, but gives the cleanest result, removing the excess load on the CPU.

Display setting and refresh rates

Modern Xiaomi smartphones are equipped with screens with refresh rates of 90 Hz, 120 Hz and even 144 Hz. However, not all games are optimized for high frequencies. In the display settings (Settings → Screen → Update frequency), you can force the maximum value, but this does not guarantee the work in the game.

Many games have their own frame limiter. Check the graphics settings inside the game itself. Often the default option is "Energy Saving" or "Standard", which limits the FPS to 30 or 45. Switching to "High" or "Maximum" FPS is necessary to get a smooth picture.

Also worth paying attention to is the screen resolution. There's a Minimum Width (DPI) item on the developer menu, which reduces the scale of the interface, but can reduce the rendering burden in some scenarios, although the effect is not always noticeable. Be careful when changing the DPI so you don't disturb the layout.

Energy saving and temperature control

Temperature is the main enemy of performance. When a Snapdragon or MediaTek processor heats up above a certain threshold (usually 40-45°C), trottling goes off, and the frequencies drop, and to avoid this, you need to adjust the power modes correctly.

In the Safety → Battery app, select Performance mode before starting the game. The standard Balanced mode can reset frequencies too early. The Energy Saving mode is categorically unsuitable for gaming, as it artificially limits the power of the processor.

⚠️ Note: Using Performance mode significantly reduces battery life.It is recommended to play with a connected charger or have a power bank on hand if you are not using an external cooler.

Physical cooling also plays a role. Remove a thick protective case during long gaming sessions. Silicone or leather covers work as a thermal insulator to keep heat from coming out. If you're serious about the outcome, consider buying an external cooler fan that attaches to the back panel.

Turn off unnecessary communication modules. If you're playing offline, turn on air mode. If you're online, turn off Bluetooth, GPS, and NFC. The constant search for networks and the operation of modules puts extra strain on the system and heats the device.

Hidden opportunities and development teams

For those who aren’t afraid to experiment, there are deeper optimization methods available. In the developer menu (Settings → About Phone → 7 times on MIUI Version → Advanced Settings → Developers) you can find options that affect the rendering work.

Find the option “Preferred GPU Mode” or “GPU Driver Settings” here, you can try to switch the driver to the system or update it through the Google Play Store (Google Play System Updates section), which sometimes solves compatibility problems in new games.

Also worth checking is 4x MSAA (aliasing), which improves the picture quality in games by making the edges of objects less jagged, but it puts additional strain on the GPU. On weak devices, this feature is better left off.

Remember to enable the Do Not Save Action option in the developer settings, which will prevent the application from being active when it is closed, which can speed up the re-start and clear the extra data from memory a little.
