Owners of Xiaomi, Redmi and Poco devices often face a situation where the case of the smartphone becomes unpleasantly hot, and the system forcibly reduces the brightness of the screen or completely blocks charging. This is not just discomfort, but a signal that thermal protection is at its limit, trying to save the processor from critical temperatures. Understanding the causes of heat is the first step to an effective solution to the problem, because in most cases the user can independently normalize the work of the gadget.
Modern mobile processors, especially in the Poco F series gaming models or Xiaomi 13/14 flagships, have enormous processing power that is inevitably transformed into heat energy. If you notice that the phone warms even in simple, this may indicate a software failure or background processes that eat up resources. In this article, we will discuss how to turn off aggressive MIUI optimization, which is often the hidden culprit of heating, and which system parameters require your attention in the first place.
Ignoring the problem can lead to accelerated battery degradation and detachment of the plumes inside the case, so it's important not just to know how to cool the device right now, but also to implement habits that prevent overheating in the future. We'll look at both software settings and physical cooling techniques that will help restore your smartphone to stability.
Diagnostics and monitoring of temperature in real time
Before we go into action to "treat" the smartphone, you need to accurately determine the current state of the thermal regime. The shell MIUI and HyperOS built in standard monitoring tool, but it often shows only the big picture. For deep diagnosis, it is better to use third-party utilities or engineering menus to see the temperature of individual components, such as the battery, processor and camera.
One of the most reliable ways to get detailed information is to use the CIT engineering menu, which requires you to enter a special code in the call app, which will allow you to see not only the current values, but also the thresholds at which the system begins trottling (decreased performance).
##6485##In the window you are interested in the parameters. MB_06 (residual receptacle) and MB_00 (The total charge, but the main thing is the codes for the temperature. MB_10 or RF_05, depending on the Snapdragon or MediaTek processor model. 45Β°C in plain, it is an alarm signal that requires immediate intervention.
And you also need to look at the applications that consume the most power, and it often turns out that the heavy app is getting stuck in the background and constantly wakes the processor up, preventing it from going to sleep, and monitoring the activity of the applications is a key element of prevention.
- π₯ Check the battery statistics in the settings to identify hidden energy eaters.
- π‘οΈ Use the Security widget to quickly assess the state of the system.
- π± Install the app CPU Throttling Test to check processor frequency stability.
- π Keep an eye on the temperature during fast charging of HyperCharge, it should not exceed 40-42Β°C.
Customize the interface and disable visual effects
The MIUI shell is famous for its beautiful yet heavy-duty interface that loads the graphics accelerator even with simple actions. Transition animations, live wallpaper and constantly updated desktop widgets make the GPU work in a heightened mode, which directly affects the heating of the case.
First of all, we recommend that you eliminate live wallpapers, which require constant rendering of graphics, which not only puts the battery down, but also keeps the temperature in good shape. Replacing them with a static image significantly unloads the system. It is also worth reviewing the number of widgets on the main screens.
Another important parameter is the refresh rate of the screen. If your smartphone is equipped with a display that supports 120 Hz or 144 Hz, switching to the standard 60 Hz in everyday tasks (reading, social networks) can reduce heating by several degrees. AMOLED-matrices, where high hertzov requires more energy.
β οΈ Warning: Disabling animations through the developer menu makes the interface less smooth visually, but significantly speeds up the system response and reduces the load on the processor.
For advanced users, there is a hidden developer menu where you can change or completely disable the animation scale. The path to it is through Settings β About Phone β MIUI version (you need to press 7 times), and then in advanced settings find the item "Animation". Setting the value "No animation" or "0.5x" does wonders with the temperature of older devices.

Try using the Classic theme or minimalist themes without complicated graphics β this will reduce the load on the rendering of the interface.
Background Process Management and Auto Start
One of the main reasons why Xiaomi's phone is so hot in your pocket is the uncontrolled autostart of apps, and a lot of software installed prescribes itself to autoboot and keeps running even when you're not using it, tracking geolocation, updating tapes and synchronizing data, creating a constant background load.
HyperOS and newer versions of MIUI have a more aggressive memory management policy, but it's not always effective. You need to manually restrict permissions for suspicious applications. Go to the battery settings, select the app, and set "No restrictions" only for instant messengers, and for the rest - "Limit background activity."
It's also worth checking your synchronization settings, and if you have high-resolution gallery synchronization enabled or backup of large amounts of data in the background, the phone will heat up, and you'd better set these processes up only when you connect to Wi-Fi and charge, or start them manually.
βοΈ Cleaning up the autoload
Remember, Expand Memory, which uses a portion of internal storage as RAM. While it's useful for multitasking, constantly writing and reading data from flash memory can cause the memory controller to heat up, and if you have enough physical RAM (8 GB or more), it's best to turn it off.
Optimization of the game mode and Game Turbo
For gamers, heating is the number one enemy causing FPS drops and trolling. Game Turbo's proprietary utility is designed to optimize resources, but sometimes its settings can be too aggressive or vice versa insufficient.
In Game Turbo settings, you can select a performance profile for each game. If you play non-demanding projects, switch to Balanced or Energy Saving mode. This will limit the maximum CPU frequency, preventing temperature spikes. For heavy games like Genshin Impact or PUBG, it is better to use Performance mode, but with the understanding that the heat will be higher.
Real-time monitoring is an important tool. The sidebar shows the current temperature of the CPU and GPU during the game. If you see the temperature coming up to the red zone, it makes sense to lower the graphics settings inside the game itself or the brightness of the screen.
| Parameter | Recommended value | Impact on heating |
|---|---|---|
| Frame rate (FPS) | 60 (or 30 for savings) | High: More frames = more heat |
| Graphics | Medium/Low | Critical: Reduces the load on the GPU |
| Screen brightness | 50-70% | Medium: The screen is the main source of heat |
| Sound. | Headphones. | Low: The speaker also warms up when working |

Reducing the graphics settings in games by one step (for example, from βHighβ to βMiddleβ) gives an increase in FPS stability due to the lack of trolling.
Network modules and the problem of weak signal
Few people think about it, but the communication module is one of the most powerful sources of heat in a smartphone. When you are in the area of insecure reception (outside the city, in the basement, in the subway), the Xiaomi phone starts frantically searching for the network, increasing the power of the transmitter, which leads to a sharp jump in temperature in the upper part of the housing where the antenna is located.
If you're in places with poor coverage, it makes sense to temporarily switch the network mode. 4G (LTE) instead 5G or 3G It can significantly reduce energy consumption. 5G-modems, especially in early implementations, are prone to strong heating even with low data load.
Also, you should turn off your constant search for Wi-Fi and Bluetooth networks if you're not using them right now. The Improving Position Accuracy feature, which scans your environment over Wi-Fi, also contributes to background heating. Turn off these features in geolocation settings for maximum autonomy and cold.

Hardware cooling and maintenance methods
When software is exhausted, physical methods come to the rescue, the simplest and most effective is to remove the protective cover during heavy use, Silicone and rubber covers work like a thermal insulator, locking heat inside the case and preventing it from dissipating through an aluminum frame or a glass back.
For owners of Black Shark or Poco gaming smartphones with active cooling, cleaning the vents is important. Dust stuffed inside disrupts air circulation. In conventional smartphones, it is also worth checking the connectors and speakers for pollution, although there the cooling is passive.
Using external coolers for smartphones is a radical but very effective solution for long gaming sessions. Back-mounted magnetic coolers can remove tens of watts of heat, allowing the processor to operate at maximum frequencies without trottling, the only way to completely turn off overheating in extreme conditions.
- βοΈ Remove the case while charging or playing for better heat exchange.
- π§Ή Regularly wipe the back panel and screen, greasy film worsens heat transfer.
- π¬οΈ Use an external fan or cooler for long gaming sessions.
- π« Do not place your phone on soft surfaces (sofa, bed) while charging.
