Why Xiaomi is on Android: all the reasons and solutions

Have you noticed that your Xiaomi smartphone has become suspiciously hot? the case heats up even at minimal load, and sometimes the device completely shuts down with a warning of overheating? This problem is familiar to many owners of Redmi, POCO and Mi lines - from the budget Redmi Note 12 to the flagship Xiaomi 14 Ultra. Overheating not only reduces performance, but also reduces battery life, and in critical cases can lead to irreversible damage to internal components.

In this article, we will analyze all possible causes of overheating, from banal battery wear to hidden MIUI firmware errors, as well as give step-by-step instructions on how to diagnose the problem and fix it without going to the service center.

1. Overheating due to high load: games, video and multitasking

The most obvious reason is the intense work of the processor and the graphics accelerator. Modern mobile games (Genshin Impact, Call of Duty Mobile, PUBG) load the chipset 80-100%, which inevitably leads to heat, but even if you are not a gamer, background processes can create no less load.

How to check? Open Settings → Battery status → CPU use. If games, instant messengers (Telegram, WhatsApp) or system processes (com.miui.home, android.system) are the leader in the list, the problem is precisely the load. Normal temperature during games: up to 45 ° C. If higher, the chipset runs at its limit.

• 🎮 Games: Even the average graphics settings in Genshin Impact warm up the Snapdragon 8 Gen 2 to 50°C+.
• 📹 Video editing: Apps like CapCut or KineMaster load all CPU cores.
• 🔄 Multitasking: Simultaneous Chrome (20)+ tabs), YouTube in the background and messengers.
• 🤖 Background processes: Auto-update apps, sync Google Photos or Mi Cloud.

⚠️ Warning: if the temperature exceeds 60°C for simple tasks (watching videos, calls), the problem is not in the load, but in hardware malfunction - read more.

2. Battery problems: wear, bloating and unoriginal RMS

The battery is one of the main sources of heat in the smartphone, and over time, its capacity decreases, internal resistance increases, and the charging/discharge process begins to be accompanied by increased heat generation, especially on older models (Redmi Note 8, Mi 9), where the battery has already been in use for 3-4 years.

How do you check for wear and tear? Type ##4636## into your phone number, go to Battery Information, and check Health Level. A value below 80% is critical.

• 🔋 Battery bloating: if the phone body is “opened” or the screen begins to bend – immediately stop using!
• ⚡ Unoriginal charging: cheap ROM from NoName brands can supply unstable voltage, which causes the power controller to overheat.
• 🔌 Fast Charge: Fast Charge Technology (33W, 67W, 120W) Heat the battery more than standard charging 5-10°C.

💡

If the battery is swelling but the phone is still working, don't try to prick or squeeze it, it could cause fire. Take it to a service center to recycle the battery.

3. MIUI firmware failures: update errors and background processes

MIUI firmware is known for its features, but sometimes they turn into problems. For example, after upgrading to MIUI 14, many users of the Redmi Note 11 and POCO X4 Pro faced constant heating due to a failure in the MiuiDaemon service, which scans the system for viruses and optimizes performance.

How to diagnose software overheating:

1. Go to Settings → About Phone → MIUI version and check the relevance of the firmware.
2. Open Settings → Applications → Application Management → System and find processes with high CPU consumption.
3. Install the AIDA64 app (free version) and check the core temperature of the processor in a simple way.

• 🔄 Failed update: if the phone began to warm up after the update, try to roll back on the previous version MIUI.
• 🛠️ Optimizers and cleaners: applications like Clean Master or DU Speed Boosters often create extra load.
• 📱 Bat versions of firmware: test builds MIUI They may contain errors that cause overheating.

Hardware malfunctions: thermopaste, processor, communication modules

If the phone is warming even when it's off or it's heating unevenly (like just the top of the case), the problem is the hardware.

• 🧪 Dried thermopaste: over time, it loses thermal conductivity, and the processor overheats. 2-3 years.
• 📡 Faulty module 5G/Wi-Fi: Qualcomm chips X60 (Snapdragon 888) MediaTek Dimensity is warmed by a bad signal.
• 🔧 Damage after falling: Even a minor impact can displace the radiator or damage power contacts.
• 🔥 Short circuit: if the phone is heated lightning fast (for the first time) 1-2 minutes), it could be a CZ on the board.

How to check for hardware problems:

1. Feel the case: If one area is hotter than the other (such as the chamber area or the bottom), this indicates local overheating of the component.
2. Listen to the phone: hissing or cracking when heated can talk about the breakdown of the capacitors.
3. Check the history of falls: even if there is no external damage, internal microcracks can manifest over time.

⚠️ Warning: If the phone spontaneously turns off when heated and does not turn on until it cools, this is a sign of the thermal protection activated.

External factors: ambient temperature and covers

Many people forget that a smartphone is a mini-computer that needs cooling, and if you leave Xiaomi in direct sunlight or in a closed car in the summer, the temperature inside the case can exceed 70°C, which will lead to:

• 🔋 Automatic Battery Shutdown (Fire Protection).
• 📱 Data loss due to overheating of flash memory.
• 🛠️ Deformation of the body or detachment of the screen.

Also, the culprits of overheating can be:

• 🧥 Tight covers: silicone or armored cases worsen heat transfer on the body 15-20%.
• 🚗 Wireless charging: Induction coils heat the body more than wired RAM.
• 💻 Use during charging: Simultaneous play and charging doubles heat release.

💡

The optimal temperature for the smartphone: from +10 ° C to +35 ° C. At +40 ° C and above, the risk of battery damage increases by 2 times.

6. Viruses and Malware: Hidden Mining Bots

An unlikely but possible cause is viruses, cryptocurrency mining, or spyware. Malware applications can use the phone’s resources to:

• 💰 Hidden mining: for example, the Loapi virus loads the processor 100% to mine Monero.
• 📊 Clicks on advertising: bots simulate user activity, loading the system.
• 📤 Data theft: constant information transfer in the background warms the modem.

How to check your phone for viruses:

1. Install antivirus (Dr.Web, Kaspersky, Malwarebytes) and perform a full scan.
2. Check the list of installed apps in Settings → Apps. Delete suspicious ones (for example, with names like System Update, Flash Player).
3. Open Settings → Battery → Battery Use and find apps with abnormally high consumption.

⚠️ Attention: if you have installed APK-files from unverified sources (e.g. hacked games), the probability of infection with the virus is up to 30.

7.How to reduce heat: practical tips

If the cause of overheating is not critical (for example, it is not a bloated battery or short circuit), try these methods:

• ⚙️ Disable unnecessary functions: 5G (if you don't use). NFC and Bluetooth in the background. Auto-update apps.
• 🔄 Limit background activity: In Settings → Apps disable auto-start for unnecessary programs. Use Power Saving mode.
• 🎮 For gamers: Reduce FPS in the game settings (e.g. 90 to 60 Hz). Use the cooler for the phone (cost: 500 Hz) ₽).

For advanced users:

Disconnecting MIUI microservices (requires root):


1. Install ADB on the PC.




2. Connect the phone and execute the command:




adb shell pm uninstall -k --user 0 com.miui.analytics




3. Reset the device.
