Xiaomi smartphones are some of the most productive in their price segment, but high power comes with higher heat, POCO X5 Pro or Mi 11 Ultra heated to 45-50°C when playing games, shooting videos or even in standby mode, this is not always a cause for panic, but constant overheating reduces battery life and can lead to trottling (automatic performance decrease).
In this article, we will look at the causes of overheating (from the banal background of applications to hardware malfunctions) and give 10 proven ways to reduce the temperature, from software settings to physical cooling methods. All recommendations are tested on models from 2020-2026 and do not require root rights. We pay special attention to hidden settings MIUI, 90% of users do not use.
1.Why Xiaomi phone is warming up: the main reasons
Overheating is always a consequence of an imbalance between heat and heat. Xiaomi has two key features that provoke the problem:
- 🔥 Qualcomm Snapdragon processors (especially series) 8xx) — high-profile TDP (For example, the Snapdragon 8 Gen 2 in the Xiaomi 13 Pro is heated to 47.°C in 15 minutes of Genshin Impact.
- 📱 MIUI Background and processes: even in standby mode, the system can keep up to 30 applications active, and com.miui.analytics and com.xiaomi.midrop load the processor on 10-15%.
- 🔋 Fast charging (33W/67W/120W) — When charged, the battery is heated to 40–42°C, and if you play at the same time, the temperature rises to critical 50°C.
- 🌡️ Poor heat sink: in budget models (Redmi) 10A, POCO M5) use thin graphite pads instead of copper tubes.
Indirect causes that exacerbate the problem:
- 📲 Poor network coverage (4G/5G): phone spends 30% processor power to search for a signal.
- ☀️ Direct sunlight or heat (>30°C: even in standby mode, the body temperature rises by 8-12°C.
- 🛠️ Thermopaste wear (relevant for phones over 2 years old).
⚠️ Warning: If the phone is heated to 50°C+ Standby (no games or charging), this is a sign of a hardware malfunction - a faulty battery, a short circuit on the motherboard or damage to the cooling system.
2. How to check the temperature of the processor and battery
Before you take action, you need to accurately measure the temperature of key components. Xiaomi has two ways:
Method 1: Hidden engineering code
In the application Phone combination:
##4636##In the menu that opens, select Battery Information.
- 🔋 Charge level (% and mV).
- 🌡️ Battery temperature (normal: 25-38)°C).
- 📶 Network status (if warmed due to bad signal).
Method 2: Monitoring applications
For detailed diagnosis, install one of the applications:
- 📊 CPU Monitor – shows the temperature of each processor core in real time.
- 🔋 AIDA64 — temperature-reflect CPU, GPU, battery and even the charging port sensor.
- 🎮 Game Bench – Tests heat during games (good for gamers).
Critical values of temperature:
| Component | Norm (°C) | Warning (°C) | Dangerous (°C) |
|---|---|---|---|
| Processor (CPU) | 30–45 | 45–50 | >50 |
| Graphics Processor (GPU) | 35–50 | 50–55 | >55 |
| Battery | 25–38 | 38–42 | >42 |
| Charging controller | 30–40 | 40–45 | >45 |
⚠️ Note: If the processor temperature exceeds 50°C regularly (not once), this leads to trottling, which is a forced reduction in the frequency of the cores. In games you will notice friezes, in benchmarks you will see a drop in points by 20-30%.
3. Software methods to reduce heating
In 80 percent of cases, overheating is eliminated by setting the system without physical intervention, and we'll start with the most effective methods.
Background processes offline MIUI
MIUI It's known for aggressive resource consumption, to reduce stress:
- Go to Settings → Applications → Application Management.
- Select AutoRun and disable autoboot for unnecessary applications (especially instant messengers and social networks).
- In the Battery and Productivity section → Battery mode select Charge Saving (limits background activity).
3.2. Restriction of performance in games
For gamers: in MIUI There is a hidden Game Turbo feature that allows you to manually limit the game. FPS and permission in games:
- Open Settings → Special features → Game Turbo
- Select the game from the list and activate the Restriction FPS (optimally: 60 instead 90/120).
- Turn on the cooling. CPU (lowers the clock frequency when heated).
☑️ Checklist for optimization MIUI
Updating firmware and core
Manufacturers regularly release patches to optimize their energy use.
- Go to Settings → About the phone → System update.
- If you have a new version of MIUI or Android, install it.
- For advanced users: Check for custom cores (like FrancoKernel) that optimize heat generation better.
Important: After the update, reset the cache in Recovery Mode (press the Power) + Volume Up when your phone is turned off, select Wipe Cache).
💡
If after the update the phone began to warm up stronger, roll back to the previous version MIUI Fastboot, or go to the service, it's a sign of a raw firmware.
4. Physical cooling methods
If the software methods didn’t work, it’s time to move to hardware solutions, which are divided into temporary (for emergency cooling) and permanent (refrigeration upgrades).
Emergency cooling (rapid methods)
- ❄️ Remove the case: even a thin silicone case increases the temperature by 3-5°C.
- 🧊 Use a cooling gel pack (sold for laptops) – apply to the back cover for 5-10 minutes.
- 💨 Direct a fan at the phone (but not the cold air conditioner air - this can cause condensation!).
- 🔌 Turn off the charging during games – this reduces heating by 10-15°C.
Long-term solutions
- 🛠️ Replacement of thermopaste: in the service it costs 800-1500 ₽. Efficiency: Reducing temperature by 5-10°C.
- 🔧 Installation of copper plate on the processor (relevant to the POCO F3/F4, where the standard cooling system is weak).
- 📱 Use of a cooling cover with a fan (e.g. Black Shark Cooling Backclip).
What happens if you ignore the heat?
5. Settings to reduce heating when charging
Fast charging is one of the main causes of overheating, and here's how to minimize the risks:
Shutting down fast charging
If you don’t need a super-fast charger (33W/67W/120W), limit the power:
- Connect the phone to the charger.
- Swipe down the notification panel and tap on Charging Mode.
- Select Standard Charging (10W–18W).
Charging in aircraft mode
Network shutdown (4G/5G/Wi-Fi) heats up 20–25%. For that:
- Activate Flight Mode in the notification curtain.
- Get the charger on.
- After reaching 80-90%, turn off the charging and exit the flight mode.
Optimum charge level
Don't keep your phone on charge all the time! Optimal range for lithium-ion batteries is 20-80%. Use Optimized Charging in Settings → Battery to automatically limit charge to 80%.
| Action. | Temperature drop (°C) |
|---|---|
| Shutting down fast charging | 8–12 |
| Aircraft charging | 5–10 |
| Removal of the cover during charging | 3–7 |
| Use of the original zoo | 5–8 |
6. Optimization of network and connections
Poor network signal or active use of communication modules (5G, Wi-Fi, Bluetooth can raise the temperature by 10-15°C. Here's how to fix it:
6.1. Switching from 5G on 4G
Module 5G It consumes 30-40% more energy than 4G. If you are not in a metropolis, where 5G Really quick, turn it off:
- Go to Settings. → SIM-maps and mobile networks → Type of network.
- Choose 4G (preferably).
6.2. Disable automatic Wi-Fi search
Constant network scanning is loading the processor to shut down:
- Go to Settings. → Wi-Fi → Additionally.
- Disable Automatic Open Network Connection and New Network Notifications.
Use of modem modem mode with caution
Internet distribution USB/Wi-Fi/Hotspot It heats up the phone as much as it does games:
- 🔌 Prefer. USB-Tethering (heats less than Wi-Fi).
- 📶 Limit speed in Settings → Modem and access point → Adjust the access point (for example, up to 10 Mbps).
- ⏱️ Use an external battery to keep your phone from running below 30%.
💡
The most effective way to reduce the heat from the network is to turn off automatic search. Wi-Fi/Bluetooth go over 5G on 4G. This increases the autonomy of the 15–20%.
7.When to contact the service: signs of hardware problems
If you’ve tried all the ways, your phone still warms to 50.°C+ In standby mode, it is likely that a hardware malfunction is to blame:
- 🔥 The phone heats up even when the screen is turned off (battery or motherboard).
- 📉 Battery discharges by 20-30% per hour in standby mode (short circuit).
- 🛠️ On the back cover there were swelling (bloated battery - the danger of fire!).
- 🌡️ Temperatures go up to 60.°C+ at the slightest load (cooling system is faulty).
Average cost of repair in the service:
| Problem. | Cost (₽) |
|---|---|
| Replacement of thermopaste | 800–1500 |
| Battery replacement | 1500–3500 |
| Repair of the motherboard (seeding of elements) | 3000–8000 |
| Installation of an additional radiator | 1200–2500 |
⚠️ Warning: If the phone spontaneously turns off when heated, it may be a sign of a malfunction of the power controller.Do not try to turn it on immediately - let it cool for 15-20 minutes, then check in the service.
8. Prevention of overheating: operating rules
To Xiaomi phone does not warm up in principle, follow these rules:
- 🌞 Avoid direct sunlight: Do not leave your phone on the torpedo of your car or windowsill.
- 🔌 Use original chargers – cheap RAM can give unstable voltage.
- 🎮 Take breaks in games: after 40-50 minutes of a game session, let your phone cool down for 10 minutes.
- 📱 Do not close the air vents (if any, as in Black Shark).
- 🔄 Regularly update the firmware in new versions MIUI Optimize energy consumption.
Optimal working conditions:
- Ambient temperature: 10–35°C.
- Humidity: up to 80% (condensation within the body accelerates corrosion).
- Charging: 20-80% (avoid full discharge and 100% charge).
💡
If you play on your phone often, buy a cooling stand with a fan (like the Baseus Cooler), which reduces the temperature by 10-15.°C by active blowing.
