Temperature standards for Xiaomi: when to sound the alarm
The manufacturer does not disclose the official limits, but based on the tests of Xiaomi and independent laboratories (DXOMark, AnTuTu), we have compiled the current standards for modern smartphones:
| Component | Norm (°C) | Warning (°C) | Critical threshold (°C) | Consequences of overheating |
|---|---|---|---|---|
| Battery | 25–40 | 40–45 | >50 | Accelerated degradation, bloating, phone shutdown |
| Processor (CPU) | 30–50 | 50–65 | >70 | Trottling (decreased productivity), shutdown |
| 5G/4G module | 35–55 | 55–65 | >70 | Network loss, reboot |
| Screen (AMOLED) | 20–45 | 45–50 | >55 | Image artifacts, pixel burnout |
What affects the temperature:
- 🎮 Games (Genshin Impact, Call of Duty Mobile) GPU 100%, warming to 60-70°C.
- 📶 Weak signal of the network – the communication module is working at its limit, warms up to 55-65°C.
- ☀️ Direct sunlight – even in standby mode, the temperature can rise to 50°C.
- 🔌 Fast charging (33W/67W/120W) — battery heated to 40–45°C.

⚠️ Note: If the processor temperature exceeds 70°C or battery - 50°C in standby mode (no load), this is a sign of malfunction:
- 🔋 Bloated battery (requires immediate replacement).
- 🛠️ Failure of the cooling system (thermopaste has detached).
- 🦠 Viral software, cryptocurrency miners.
4. Hidden engineering menus: Advanced diagnostics
For power users, Xiaomi offers service codes that allow access to low-level data. These menus are not documented, but work on most models (except for the low-level ones). POCO custom-made).
List of useful codes:
- # #6484## - Hardware test (Battery tab shows temperature and voltage).
- #64663## - Testing menu (Thermal section with heating graphs).
- ##284## - Communication module test (indicates antenna temperature)
- ##232338## — MAC-address and temperature of the Wi-Fi module.
Example of use (code ##6484##):
- Enter the code in the Phone app.
- Choose. MB Test (or Manual Test).
- Go to the Battery section.
- Note: Battery Temp - Battery Temperature. VBAT — voltage (normal: 3.7-4.4 V). Charging Status - charging status.
