Xiaomi phone is hot: 10 real reasons and what to do about it

Your Xiaomi Redmi Note 12, POCO X5 Or did the Mi 11 get hot like an iron and the battery goes down in half an hour? Smartphone overheating is one of the most common complaints of users, and there are specific reasons for this problem, and 90 percent of the time it's not the fault, but the wrong settings, background processes or external factors. But how to distinguish normal heating from critical, when it’s time to run to the service?

In this article, we will analyze all possible causes of overheating - from banal charge to hidden viruses, as well as give step-by-step instructions on how to cool the Xiaomi phone without harming the battery. 2022-2026 years, including the Redmi Note 13 Pro+ and POCO F6), where overheating is often associated with new Snapdragon chips 7+ Gen 2 Dimensity 9000+. You will also learn what temperatures are considered normal for modern Xiaomi smartphones, and when heating signals the imminent death of the battery or processor.

1.What is the temperature of Xiaomi phone considered normal?

Many users panic, barely feeling the warm body, but actually heating up to 40-45°C is absolutely normal for most smartphones. The Qualcomm and Mediatek processors that Xiaomi installs are designed to work at high temperatures:

⚠️ Warning: If the temperature is above 60°C (can be checked in the engineering menu or through applications such as: AIDA64), In such cases, the smartphone can automatically turn off to avoid damage to the battery, especially dangerous for models with polymer batteries (for example, Xiaomi 13 Ultra), where the risk of swelling is higher.

How do you know the exact temperature? Install one of these apps:

• 📱 CPU Monitor – shows the temperature of the processor, battery and screen in real time.
• 🔥 AIDA64 — Detailed diagnostics of all components (including Xiaomi sensors).
• 📊 AccuBattery – monitors battery heating during charging and discharging.

2. TOP-5 Why Xiaomi is warming up (and how to fix them)

Let's look at the most common causes of overheating, starting with the simplest ones. Most of them can be solved by themselves. 5-10 minute.

🔋 Reason 1: Fast charging (especially on cheap adapters)

Xiaomi is known for its ultra-fast charging technology: HyperCharge 120W (In the Mi 11 Pro, Turbo Charge 67W (into POCO F4 GT) even 200W But the higher the power, the more the phone heats up.

🔹 What do you do:

• 🔌 Use the original charger from the kit. Cheap analogues often can't handle the load and overheat the battery.
• ⚡ Turn off fast charging in settings: Settings → Battery → Charging settings → Fast charging.
• ☀️ Do not charge your phone in the sun or in a hot room (above 30)°C).

💡

If the phone warms up even with the original charger, try charging it in aeromode - this will reduce the load on the processor and reduce heating.

🎮 Reason 2: Genshin Impact (Call of Duty, PUBG)

Xiaomi models on Snapdragon 8 Gen 2 or Dimensity 9200 chips (e.g. Redmi) K60 Pro or Xiaomi 14) are basking in games because of high performance (POCO X5, Redmi Note 12 can overheat if the game is optimized poorly.

🔹 Decisions:

• ⚙️ Lower your graphics in the game settings (e.g. from Ultra to High).
• ❄️ Enable Performance Mode in Settings → Special facilities → Play mode and choose the balance between performance and heating.
• 🛡️ Use a cooling case or fan stand (such as Black Shark FunCooler Pro).

📱 Reason 3: Background processes and viruses

If the phone is warming up even in standby mode, the problem may be in the background activity of applications or malware. APK or games from unknown sources.

🔹 How to check:

1. Open Settings → Applications → Permissions → Autostart and disable autostart for unnecessary programs.
2. Check battery consumption: Settings → Battery → Battery use. If an application consumes >10% in the background - remove it.
3. Scan your phone with an antivirus (Malwarebytes or Dr.Web Light).

🌡️ Reason 4: Dust in the charging connector or under the cover

Over time, dust accumulates in the USB-Type C port, which worsens heat transfer. 13T) dust can block the ventilation holes.

🔹 What do you do:

• 🧹 Clean the connector with a soft toothbrush (not metallic!).

• ⚠️ Do not use alcohol or liquids – they can damage contacts!

🔄 Reason 5: Outdated firmware or beta MIUI

If the phone started warming up after the upgrade, it could be the fault of unstable firmware, especially for beta versions. MIUI Or custom firmware (LineageOS, Pixel Experience).

🔹 Decision:

• 📲 Check for updates: Settings → The phone. → Updating the system.
• 🔙 If the problem appears after the update, make a rollback to the stable version through the Mi Flash Tool.
