Xiaomi smartphones are some of the most popular devices on the market, but many users are facing their overheating.The increased temperature not only reduces performance, but also accelerates battery wear and in extreme cases can lead to a sudden shutdown or even damage to internal components.The reasons for heating range from background MIUI processes to physical factors such as direct sunlight or a faulty battery.
In this article, we will analyze all possible causes of overheating - from the banal use of resource-intensive games to hidden firmware errors. You will learn how to diagnose a problem using Xiaomi’s built-in tools, what system settings should be optimized, and when it is time to contact the service center. MIUI, Helps to reduce the temperature of the processor without loss of performance.
Why Xiaomi is warming up: the main reasons
Smartphone overheating is rarely an accident, usually the result of a combination of factors, and here are the most common reasons why your Redmi, POCO, or Mi can turn into a pocket heating pad:
- 🔥 Intense load: games with high demands (Genshin Impact, Call of Duty Mobile), video rendering or long-term recording in the video 4K.
- 📱 Background processes: automatic updates, synchronization of cloud services (Mi Cloud, Google Drive), widgets.
- 🔋 Battery problems: battery wear (more than 500 charging cycles), use of non-original chargers.
- 🌡️ External factors: direct sunlight, high ambient temperature (above 35)°C), tight cover.
- 🛠️ Software errors: bugs in the firmware MIUI, conflicting applications, viruses.
- 📡 Network loads: weak signal 4G/5G Wi-Fi, or constant network search.
Interestingly, even the color of the case can affect heating: Xiaomi’s black and dark models heat up 5 to 10 percent more than light under the same conditions, due to the physical properties of heat absorption.
⚠️ Warning: If the body temperature exceeds 45°C in standby mode (no active use), this may indicate a motherboard malfunction or short circuit in the battery.
How to check the temperature of Xiaomi: built-in and third-party tools
Before you take action, you need to know exactly what part of the smartphone overheats. Xiaomi devices have several ways to monitor the temperature:
- Secret Menu of Engineering Settings: Enter the phone app for ##4636##, then select Battery Information. This displays the battery temperature in real time.
- Security: Go to Security → Optimization → Temperature. The system will show the temperature of the processor, battery and screen, and will also suggest optimizing the load.
- Third-party utilities: Applications like CPU Monitor or AIDA64 provide advanced information, including the temperature of each processor core, GPU, and even environmental sensors.
| Component | Normal temperature (°C) | Critical temperature (°C) | What do you do? |
|---|---|---|---|
| Processor (CPU) | 30–40 | 70+ | Close applications, reduce brightness |
| Graphics Processor (GPU) | 35–45 | 80+ | Limit FPS in Games |
| Battery | 25–35 | 50+ | Turn off the charger, let it cool down. |
| Screen. | 20–30 | 45+ | Reduce brightness, turn off AOD |
Important: Temperatures can temporarily rise to 50–60°C when charged with a Quick Charge 4+ or HyperCharge.This is normal, but if the heat is maintained after full charging, check the cable and power supply.
💡
If the processor temperature jumps sharply to 60-70°C for no apparent reason, try restarting your smartphone in Safe Mode (hold the power button → “Reboot Safe Mode”). If the heating is gone, one of the installed applications is to blame.
Software Ways to Reduce Heat
Most overheating problems are solved at the software level.MIUI offers several hidden features that help optimize the load on the processor and battery.
1. Optimization of background processes
By default, Xiaomi aggressively caches apps in memory, which can lead to unnecessary loading, to limit background activity:
- 📱 Go to Settings. → Annexes → Application management.
- 🔍 Select an app that heats up your device (like Facebook or TikTok).
- 🚫 Click Limit Background Activity and Disable Auto Start.
2. Set-up of performance mode
MIUI has a hidden Battery Saver mode that automatically lowers the CPU clock speed when it's heated.
- Open the settings → Battery and performance.
- Select Performance Mode → Balanced or Saving Charge.
- Activate the option Optimize when overheating (available on MIUI 12+).
3. Disabling unnecessary functions
Some Xiaomi features work in the background and load the processor:
☑️ What to turn off to reduce heating
Critical: If your smartphone is warming up even in standby mode, check the list of recent apps. Sometimes MIUI doesn't shut down processes completely, it just freezes them. To completely stop the application, swipe it up and click Close everything.
Hardware cooling methods
If the software settings don't work, it's time to pay attention to the physical condition of the device.
- 🧊 Use cooling stands: For gamers, stand with fans (for example, Black Shark Cooler), which are connected by the USB-C And they lower the temperature by 10 to 15.°C.
- ☀️ Avoid direct sunlight: Even 10 minutes in the sun can raise the temperature of the screen to 50°C. Use covers with light reflective surfaces.
- 🔌 Proper Charging: Do not use your smartphone while charging with a fast charger (67W/120W). If you need to call urgently, turn off the charging or go to 10W-regime.
- 🧹 Cleaning connectors: Dust and dirt in USB-C Or speakers can block the heat sink. Clean them carefully with a wooden toothpick.
Emergency method: If your smartphone overheats and shuts down, don't turn it on right away. Let it cool in the shade for 15-20 minutes, then plug it into charging for 5-10 minutes before turning on.
⚠️ Warning: Never put an overheated smartphone in the fridge or freezer! a sharp temperature drop can cause condensation inside the case, which will lead to a short circuit.
What to do if Xiaomi is overheated and not turned on?
Cooling for gamers: special settings
If you’re actively playing on Xiaomi, standard cooling techniques may not help.
- FPS Limitation: Most games (like PUBG Mobile or Free Fire) can manually set frame limits, with an optimal value of 30 FPS or 40 FPS (instead of 60/90 FPS) that will reduce the load on the GPU by 20–30%.
- Use Game Turbo: MIUI has a built-in Game Turbo mode that optimizes resources. Activated via notification when you launch a game or in Settings → Special Features → Game Turbo.
