Xiaomi smartphones are some of the most popular devices on the market, but even they are not immune to overheating. If your device gets hot like a pan, or suddenly turns off with a high temperature warning, it’s a signal to action. Overheating not only reduces performance, but can irreversibly damage the battery, processor or even the screen. In this article, we’ll look at why Xiaomi is warming up (including Redmi models, POCO and flagship series), and what to do about it – from basic methods to advanced solutions.
It's important to understand that overheating isn't always a breakdown. It's often the software settings, background processes, or external conditions that are to blame. But if the temperature is above 45 to 50°C in normal mode (like watching a video), it's time to sound the alarm. We've put together proven cooling methods that work on all Xiaomi devices, from the budget Redmi Note to the top-end Xiaomi 14 Ultra.
Why Xiaomi is warming up: 5 main reasons
Before you cool your smartphone, you need to understand what caused the overheating, and here are the most common reasons that apply to all Xiaomi models:
- 🔥 Intensive load: games (Genshin Impact, PUBG Mobile, videotaping in 4K, Rendering or multitasking: Xiaomi's Snapdragon and Mediatek processors are prone to heat up at maximum load.
- 📱 Background processes: auto-update applications, synchronize Google Drive/Mi Cloud, viruses or “heavy” messengers (Telegram with a thousand chats).
- 🔋 Battery problems: battery wear (especially after 500 charging cycles), use of non-original chargers or fast charging (HyperCharge, Turbo Charge).
- 🌡️ External factors: direct sunlight, high ambient temperature (above 30)°C), a tight cover or use of the device in a closed space (e.g. in a car in the sun).
- 🛠️ Hardware malfunctions: high thermal paste on the processor, damaged radiator (in Black Shark game models), or factory defect.
If your Xiaomi is warming up even in standby mode, it is a worrying sign, most likely due to background processes or a faulty battery, in which case radical measures, which we will discuss below, will help.
How to Check Xiaomi Temperature: Hidden Tools
Before you cool your smartphone, make sure there's a problem. Xiaomi has built-in temperature monitoring tools, but they're hidden in the engineering menu. Here's how to open them:
- Open the phone app and enter the combination: ##4636##
- Select Battery Information, which shows the battery temperature in degrees Celsius.
- For more detailed diagnostics, use applications like CPU Monitor or AIDA64, which show the temperature of the processor, GPU, and other components.
Normal indicators for Xiaomi:
| Component | Normal temperature (°C) | Critical temperature (°C) |
|---|---|---|
| Battery | 25–35 | 45+ |
| Processor (CPU) | 30–45 | 60+ |
| Graphics Processor (GPU) | 35–50 | 70+ |
| Screen (with prolonged use) | 40 | 50+ |
If the CPU temperature is above 60°C and the battery temperature is 45°C, the smartphone can automatically shut down to prevent damage, and in such cases urgent action is required.
⚠️ Warning: If the temperature rises to critical levels after cooling, it is a sign of a hardware malfunction (for example, a detached thermopaste or a damaged chip), in this case only the service center will help.
Xiaomi’s Emergency Cooling Techniques (If Your Smartphone Is Already Hot)
If your Xiaomi is getting hot, act fast:
☑️ Xiaomi's Emergency Cooling
What can't be done:
- ❄️ Putting the smartphone in the freezer or under a stream of cold water will lead to condensation inside the case and short circuit.
- 🔌 Continue charging the device – fast charging (Fast Charge) increases heating.
- 🎮 Run resource-intensive applications until the temperature normalizes.
If the smartphone is turned off due to overheating, let it cool for at least 15-20 minutes before re-energizing. Otherwise, you risk damaging the motherboard.
💡
To speed up cooling, place your smartphone on a metal surface (such as an aluminum stand) – it will drain the heat.
Software Ways to Reduce Heat Xiaomi
If you overheat regularly, start by optimizing the software part.
1. Disable unnecessary background processes
Go to Settings → Applications → Application Management and disable auto-start for unnecessary programs.
- 📊 Social networks (Facebook, Instagram – they constantly sync data).
- 📧 Mail (Gmail, Mi Mail).
- 🎵 Music services (Spotify, Yandex Music).
2. Limit processor performance
Xiaomi has a hidden CPU limiting feature to reduce heat: Activate it through Settings → Special features → Performance optimization (some models may have different paths), and the alternative is to use applications like the Throttling CPU (root rights required).
3. Update firmware
The manufacturer regularly releases patches to optimize power consumption. Check the updates in Settings → About Phone → System Update. If a new version of MIUI is available, install it.
⚠️ Attention: On models POCO F3 Xiaomi 11T post-update MIUI 14 users complained about the increased heat. If you notice a deterioration, roll back to the previous version via Fastboot.
4. Enable the power saving mode
Activate it in Settings → Battery → Power Saving Mode. This will limit background activity and reduce the load on the processor.
💡
Xiaomi’s Ultra Battery Saver mode shuts down all background processes and limits application performance, but significantly prolongs battery life and reduces heat.
Hardware cooling methods: from covers to coolers
If software isn't working, it's time to think about hardware.
1.Use a cooling case
Special cases with graphene inserts or aluminum plates remove heat from the case.
- 📱 Xiaomi Cooling Backplate (official accessory for gaming smartphones).
- 🧊 Baseus Cooling Case (with liquid cooling).
- ❄️ Black Shark Cooling Back Clip (Shot for Black Shark) POCO F4 GT and Black Shark 5).
2.Put an external cooler on
For gamers and users who often edit videos, suitable USB-cooler:
- 🎮 Razer Phone Cooler (with adjustable fan speed).
- 💨 IPEGA PG-9087 (fit-hold).
They connect via USB-C and are powered by a smartphone, but the efficiency justifies the energy costs.
3. Replace the thermopaste (for advanced users)
If you're an electronics repair expert, you can replace the thermal paste on your processor yourself.
- 🧴 Arctic MX-6 (It does not conduct electricity, it is safe for chips).
- 🔥 Thermal Grizzly Kryonaut (for extreme cooling).
Warning: Disassembling your smartphone is not warranty-- if you're not sure, contact the service.

What to do if Xiaomi is warming up when charging
Fast Charge (HyperCharge) is one of the main causes of overheating. Here's how to minimize the risks:
- 🔌 Use Xiaomi's original charger.Non-original power supplies can give off unstable voltage.
- 📉 Turn off the smartphone while charging or transfer it to air mode – this will reduce the load on the processor.
- 🔋 Don't play or watch videos while charging. not even Netflix in Full HD It can raise the temperature by 10-15°C.
- 🌡️ Charge the device in a cool place (for example, on a table, not under a pillow).
Critical fact: on Xiaomi models that support 120W charging (such as the Xiaomi 11T Pro), the battery temperature when charging can reach 40-45 ° C — this is normal, but reduces battery life by 15-20% per year. If you want to extend the life of the battery, charge the device by 50-80% and avoid full discharge.
| Xiaomi model | Max. charging power (W) | Recommended charging temperature (°C) |
|---|---|---|
| Redmi Note 12 Pro+ | 120 | 10–35 |
| POCO F5 | 67 | 10–40 |
| Xiaomi 13 Lite | 67 | 10–38 |
| Black Shark 5 Pro | 120 | 5–30 |
When to contact the service: signs of serious problems
If none of these methods worked, and the smartphone is still warming, then you should go to the service center.
- 🔥 Overheating in standby mode (even when the screen is off).
- 📉 Fast battery discharge (from 100% to 0% in 2-3 hours without loading).
- 💥 Battery bloating (smartphone case deformed).
- 🛠️ Permanent spontaneous resets.
- 🌡️ Processor temperature above 70°C at minimum load.
The service will check:
- Thermopaste and radiator condition.
- Integrity of the motherboard (for microcracks).
- Power controller operation (a common cause of overheating when charging).
The cost of diagnostics in official Xiaomi services is from 500 to 1500 rubles. Repair (replacement of thermopast, battery or chip) will cost 2000-8000 rubles, depending on the model.
⚠️ WARNING: If your Xiaomi is on warranty, don't disassemble it yourself! opening the case will void warranty obligations.
