Why Redmi Note 8 Pro is overheating and when to turn on cooling
Xiaomi Redmi Note 8 Pro is equipped with a powerful processor MediaTek Helio G90T, which under intense loads (games, 4K video shooting, multitasking) can heat up to 45-50 ° C. In most cases, this is normal - the system automatically adjusts the temperature. However, if the phone heats up above 55 ° C or begins trottling (forced performance decline), it is time to intervene.
Turning on the cooling mode helps:
- 🔥 Prevent emergency shutdown due to overheating;
- 🎮 Improve stability FPS play (PUBG Mobile, Genshin Impact);
- 📸 Avoid artifacts during long-term video shooting;
- 🔋 Extend battery life (lithium-ion batteries degrade faster at high temperatures).
But it's important to understand that artificial cooling is always at the expense of performance, for example, in games, frames may fall and background processes will be suspended, so you should only use this mode when you really need it.
📊 Your Redmi Note 8 Pro is overheating frequently?
Yeah, especially in games.
Only in summer.
Never noticed.
I don't know how to check.
The easiest method is to use the built-in Performance Mode feature in MIUI, which limits background processes and reduces the CPU clock speed, indirectly reducing heat.
Instructions:
- Open the settings → Battery and performance.
- Select the Productivity Mode item.
- Activate Balanced or Charge Saving option (the second option restricts heating more).
Check the current temperature in Settings → About phone → System status |
Close all background apps (especially instant messengers and games) |
Connect your phone to charge if the battery level is below 20% |
Turn off mobile internet and Wi-Fi during setup (optional)-->
Important: In some versions of MIUI (e.g. MIUI 12.5 and later), this item may be called Performance Optimization. If you don't find it, upgrade your firmware or use alternative methods.
⚠️ Warning: Charge Saving mode disables background data synchronization (for example, for WhatsApp or Telegram.
The Redmi Note 8 Pro has a hidden engineering menu where you can manually limit the processor’s heat, which works on all versions of MIUI, but requires caution – incorrect settings can impair performance.
Steps:
- Open the phone app and enter the combination: ##4636##
- In the menu that opens, select Battery Information.
- Scroll down to the Temperature block - the current battery and processor heating is displayed here.
- Return to the main menu and select Battery Usage Statistics → Menu (three dots in the upper right corner) → Battery Optimization.
- Activate the option to limit background activity.
This method doesn't involve cooling directly, but it reduces the load on the processor, which indirectly reduces the temperature. For more aggressive cooling, move to the next method.
What to do if the engineering menu is not opened?
If nothing happens after entering ##4636##, check: 1. Are third-party admin rights disabled (e.g. Greenify). 2. Are third-party launchers installed (e.g. Nova Launcher). 3. Is the firmware updated to the latest version. MIUI 13+ Access to the engineering menu may be blocked.—> Processor Temperature Status of Recommendation 30-40°C Refrigeration rate is not required 41-50°C Increased load Close background applications, activate Balanced 51–60 mode°C Overheating Enable forced cooling, interrupt games/video 60°C+ Critical overheating Turn off phone immediately, let cool for 10-15 minutes Method 3: Coolify Apps, CPU Cooler: If built-in methods don’t help, you can use third-party utilities. They work on two principles: RAM cleaning – closing background processes; Clock frequency limitation CPU (Best apps for Redmi Note 8 Pro: ❄️ Coolify automatically closes unnecessary processes and displays real-time temperature; 🔄 CPU Cooler – analyzes the heating and offers to optimize the settings; 🛡️ Greenify freezes background applications, reducing the load on the processor. Important: applications without root rights can only clean up RAM, but do not directly affect the cooling of the processor. Full control requires unlocking the bootloader and installing a custom core (for example, KernelSU). ⚠️ Note: Some of the coolers on Google Play contain adware or viruses. Only download apps rated above 4.5★ and the number of downloads from 1M+. Method 4: Cooling through ADB-Teams (for advanced) If you are willing to work with ADB (Android Debug Bridge, you can manually limit the performance of the processor. This method does not require root rights, but you need debugging settings. Instruction: Activate Developer Mode: go to Settings → The telephone and 7 once you click on the version MIUI. Back to Settings → Additionally. → For developers and enable debugging by USB. Connect your phone to your PC, install it. ADB Tools and execute command: adb shell settings put global thermal_engine_enabled 1 To limit clock frequency CPU (for example, before 1.8 GHz) use: adb shell "echo" 1800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq" These commands will temporarily reduce productivity but reduce heat. To get it back, restart your phone or do: adb shell "echo" 2000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq" 💡ADB-The commands are reset after the reboot. The constant effect requires root or automatic scripting through Tasker. 5: Physical cooling (covers, coolers, heatpaste) If software methods do not help, it is worth considering physical cooling methods: 🧊 Cooled cases – for example, Xiaomi Game Cooling Case with fan (connects to the fan) USB-C); 💨 External coolers – attached to the back panel and blow the body (for example, Black Shark FunCooler Pro); 🔧 Replace thermopaste – if the phone is older 2 For years, the factory paste could dry (requires disassembly); ☀️ Avoid direct sunlight – even in hot weather, temperatures can rise by a few hours 10–15°C. For extreme cases (for example, streaming games) you can combine several methods: + program-limit CPU. But remember, external coolers drain the battery faster because of the extra power. What NOT to do when the Redmi Note 8 Pro overheats Some "tips" from the Internet can hurt the phone: ❌ Phone room in the refrigerator - a sharp temperature drop will damage the battery; ❌ Use of alcohol or liquids for cooling – the risk of short circuit; ❌ Disconnecting Automatic Temperature Control in Engineering Menu; ❌ Installation of custom firmware without experience – unstable cores can aggravate overheating. If the phone overheats even in a simple (for example, when watching a video), this may indicate that the phone is not in a good position: 🔋 Battery malfunction (blowning, degradation); 🛠️ Damage to the heat paste between the processor and the radiator; 🦠 Viral software, miner or Trojan that loads CPU. 💡If the temperature is above 60°C without load - call the service center. This could be a hardware malfunction. FAQ: Frequent cooling questions for the Redmi Note 8 Pro: Can you turn on the cooling on the Redmi Note 8 Pro without root rights? Yes, but the options will be limited. You can: Use Performance Mode in the settings; Install applications like Coolify (they clear RAM, but do not change the frequency). CPU); Limit background processes through Settings → Battery: You need root or to control the cooling completely. ADB. Why After Updating to Update MIUI 13 phone warmed up more strongly? In the new versions MIUI Xiaomi has added aggressive optimization for gaming, which can lead to: GPU; Blocking background processes (which makes cooling systems inefficient); Bahamas in clock control CPU. Solution: back on MIUI 12.5 or use ADB-How do you check the temperature of the processor in real time? There are several ways: Using the engineering menu (#4636## → Battery information); Annexes CPU Monitor AIDA64; Desktop widgets (e.g. Simple System Monitor) Normal temperature under load up to 50°C. If higher, it's time to take action. Do cooling stickers help the body? Gel filler stickers (such as those from Baseus) have a minimal effect, reducing the body temperature by 2-5.°C, but does not affect the heating of the processor. More effective: fan cases; heat pads (installed when the phone is disassembled); external USB-powered coolers. Can you turn off trottling when you overheat? Technically, but it's highly discouraged. Trottling is a protective mechanism that prevents: battery damage; chipset failure; spontaneous shutdown of the phone. If you turn it off through a root or modified core, the phone can overheat to 80°C+, leading to irreversible breakage.
