How to speed up the processor on Xiaomi: the complete guide

Owners of Xiaomi, Redmi and POCO smartphones often face a gradual decline in device performance. Over time, the operating system becomes cache-rich, background processes consume resources, and games begin to slow down even on powerful hardware. The question of how to speed up the processor on Android becomes especially relevant when the interface begins to slow down and applications open longer than usual.

There are many ways to reanimate a device, from simple settings in the developer menu to deep interference with system files. It's important to understand that overclocking the processor is not magic, but fine-tuning frequency bars and power management. Not all methods are safe, and some require superuser rights (Root).

In this article, we will discuss both the software and hardware aspects of speeding up a smartphone, you will learn what settings are hidden in the engineering menu, how to use tweaker apps correctly, and whether it is worth climbing into the core of the system for extra hertz.

System preparation and resource cleanup

Before aggressive acceleration methods are used, the software part needs to be cleaned up. Often the brakes are not caused by a lack of CPU power, but by overflowing RAM or fragmentation of storage. The first step is to remove or freeze unused applications that are hanging in the background and consuming CPU clocks.

Special attention should be paid to system services MIUI Xiaomi’s shell is famous for its gluttony, but many features can be turned off without losing functionality. For example, advertising in system applications and constant cloud synchronization can put a strain on the memory controller and processor.

If internal memory is over 85% full, the speed of reading and writing data drops, causing the processor to stand idle while waiting for data, cleaning up garbage through a standard Security tool or third-party utilities like SD Maid will help free up resources.

• 🧹 Remove any unused apps and games you haven’t used in the past 3 months.
• 🗑 Clear the cache of system applications, especially browsers and instant messengers, which are prone to sprawl.
• 📉 Turn off live wallpaper and dynamic themes as they constantly load the graphics accelerator.
• 🔄 Reboot your smartphone after cleaning to reset the hanging processes and update system tables.

After doing the basic cleaning, you may notice that the interface is more responsive, but if the goal is to make the most of the hardware for games or heavy tasks, you will need to make more in-depth adjustments.

Settings for developers: hidden potential

One of the safest and most effective ways to speed up visual responsiveness is to activate the developer menu, which hides the parameters that affect the speed of rendering animations and the operation of background processes. To get there, you need to go to Settings → About Phone and quickly click on the version of MIUI 7 times.

In the menu that opens, find the section related to animation. Standardly, the Windows Animation, Transition Animation and Animation Duration scales are set to 1x. Changing this parameter to 0.5x or completely shutting down (0x) creates the illusion of a sharp acceleration of the system. The smartphone begins to respond to touches instantly, without delays in rendering transitions.

⚠️ Warning: Disabling animations completely can make the interface twitchy and unusual. 0.5x.

Another important parameter is the limitation of background processes. In the same developer menu, you can find the item "Limit of background processes." By default, the system decides how many applications to keep in memory. A forced restriction, for example, to "No more than 2 processes", will free up RAM and reduce the load on the CPU, since the system does not have to constantly "kill" and restart applications.

Also worth noting is the option “Enable 4x MSAA” (if available on your device), which improves graphics in games by making the processor render better. However, on weak processors, this can lead to overheating and FPS drops, so use this setting with caution.

The developer settings don’t increase the CPU clock speed physically, but they optimize task allocation, especially for devices with a small amount of RAM, where every megabyte counts.

Use of applications for overclocking (Root rights)

Real CPU frequency changes require root access rights. Without them, no application can change the kernel settings. The leaders in this niche are Kernal Adiutor, Tweaker CPU, and Franco Kernel Manager. These tools allow you to manage the Governor CPU profile and set the minimum and maximum frequencies for each core.

The overclocking process starts with the choice of a control profile (Governor). The standard interactive profile balances between performance and battery, dramatically raising the frequency when loaded. For maximum speed, you can choose a performance profile that will keep the processor at maximum frequencies constantly, ignoring the simple one. This is guaranteed to speed up work, but will lead to rapid discharge and heating.

It is important to understand the difference between minimum and maximum frequency. Raising the minimum frequency (e.g. from 300 MHz to 800 MHz) will make the phone run faster on simple tasks, but can cause the device to heat up even in the pocket.

Some processors, especially those from MediaTek and older Snapdragon models, have hidden potential. With the Tweaker CPU, you can try to raise the upper bar of frequency above the factory, but it's a lottery: one chip can run at 2.5 GHz, and the other chip will start to emit errors at 2.3 GHz.

• 📈 Raise the minimum frequency for the first (most powerful) core to speed up application launches.
• ⚡ Use an interactive or ondemand profile for everyday use to save the battery.
• 🔥 Watch the temperature: if it exceeds 45-50 Degrees in simplicity, frequencies should be reduced.

⚠️ Warning: Changing the kernel settings can lead to a "bootloop" (cyclical reboot).Always have a computer and recovery instructions on hand via Fastboot.

Engineering menu and hidden parameters

The Engineering Menu is a powerful tool for diagnosing and customizing equipment, available on many Xiaomi smartphones, and can be logged in via the codeset ##3646633## in the Phone app. If the code doesn't work, you'll need to install a special assistant app, such as the MTK Engineering Mode for MediaTek processors.

Inside the engineering menu, we're interested in the Hardware Testing → Power → CPU Enhancement section, where you can find settings that affect how the processor works. However, unlike root tweakers, here changes are often more global in nature and can concern power management at the driver level.

One of the useful features in this section is Scenario Profile, which can increase the game's performance from Balanced, and you can set up Thresholds to get the processor to go to high power earlier.

It’s worth noting that new Snapdragon processors often block access to these settings through the engineering menu, and owners of these devices will have to rely on root rights or custom cores. For owners of MediaTek (Helio, Dimensity), this method remains one of the most effective.

Comparison of optimization methods

To make it easier for you to choose the right way to accelerate, we have compiled a comparative table that will help you assess the risks and potential benefits of each method.

As you can see from the table, safe methods only have a cosmetic effect. Real performance gains in hertz are possible only if you have superuser rights. However, for most users, a combination of cleaning and tuning animations is enough.

If you decide to install a custom core, remember that this requires unlocking the bootloader. On Xiaomi smartphones, this is the official procedure, but it takes 7 to 168 hours of waiting. Once unlocked, the software warranty can be lost.

💡

Before installing a custom core, be sure to find its theme on the 4PDA or XDA Developers forum. read the last pages of the discussion to make sure the version is stable for your model.

The effect of temperature and trottling

Often, users try to speed up the processor without realizing that its speed is limited by the cooling system. A modern smartphone, when it reaches a critical temperature (usually 45-50 ° C on the body), triggers the trottling mechanism. The processor forcibly resets the frequencies to cool down, and the performance drops significantly.

The use of external coolers for smartphones (especially popular in mobile gaming) allows the Snapdragon 865/870/8 Gen 1 processor and other hot chips to keep the maximum frequencies much longer.

Also, remove the case during heavy games or tests. A tight silicone or leather case creates a thermos effect, keeping the heat from going away. In the summer, play indoors with air conditioning or in front of a fan.

• ❄️ Use external coolers (Fan Cooler) for games at high graphics settings.
• 📵 Remove the protective case during resource-intensive tasks or charging.
• 🌡 Install a temperature monitoring app to know your device’s trottling thresholds.

Ignoring the temperature regime not only slows down the phone, but also accelerates battery degradation. Lithium polymer batteries are extremely sensitive to heat, and constant operation at the limit can swell the battery in a year.

Frequently Asked Questions (FAQ)

💡

The safest way to start is by setting up animations and cleaning the system. You only need to get into the CPU frequencies if you understand the risks and have recovery tools (TWRP, computer, original firmware) at hand.

So to sum up, it's possible to speed up the processor on Xiaomi, but it requires a careful approach. Start with safe optimization methods, and only if they're not enough, move on to root rights and frequency changes. Remember, stability is more important than a couple extra frames per second.
