Xiaomi Redmi Note 8 Pro overheats: how to quickly cool your smartphone

Xiaomi Redmi Note 8 Pro is one of the most popular mid-range smartphones, but its owners often face the problem of overheating, especially when playing long games, shooting videos in the video game. 4K Unlike the flagship models, the Redmi Note 8 Pro does not have an active cooling system, so the heat sink depends on the design of the case and software optimization.

Overheating not only reduces performance, but can also lead to trottling (automatically lowering the processor frequency), rapid battery discharge, or even damage to internal components. In this article, we will discuss the unique features of cooling this model, including hidden settings. MIUI, hardware modifications and emergency measures in critical heating.

It is important to understand that if the temperature exceeds 45°C in plain or 55°C under load is a cause for concern, but not all cooling methods are equally effective: some can even make the problem worse.

Why is the Redmi Note 8 Pro hotter than other smartphones?

The main reason is the MediaTek Helio processor. G90T, It's a 12nm processor, although powerful, while competitors have already used 7nm, which means less energy efficiency and more heat. In addition, the Redmi Note 8 Pro has a liquid metal heat sink, which over time may lose efficiency due to oxidation.

Other factors:

• 🔋 Fast charging. 18W: when used during charging, the temperature can rise to 48-50°C.
• 🎮 Game mode: forcibly overclocks the processor, blocking restrictions on heat generation.
• 📱 MIUI-Optimization: Background processes and application auto-runs create additional load.
• 🌡️ Case design: plastic back panel less likely to remove heat than metal or glass.

In laboratory tests, Redmi Note 8 Pro showed heating up to 52°C after 30 minutes of play PUBG Mobile at maximum settings. For comparison, Redmi Note 10 Pro (with Snapdragon) 732G) In the same conditions, heated to 43.°C.

⚠️ Warning: If the smartphone is heated above 60°C (can be checked in the engineering menu by code ##4636##), this may indicate a battery failure or detachment of the thermal paste between the processor and the heat sink.

Software cooling methods: settings MIUI and hidden functions

Before you disassemble a smartphone or buy cooling accessories, try to optimize the system. MIUI There are built-in tools for temperature control.

Turning off background processes:

• 🛠️ Go to Settings. → Annexes → Autostart and disable Autostart for unnecessary programs.
• 🔄 B Settings → Battery → Select the option “Balanced” (not “Performance").
• 🚫 B Settings → Additionally. → Confidentiality → Special permits → Background work limit applications that actively use the processor.

2. Game mode setting:

Game turbo mode (Settings) → Special facilities → The game turbo, by default, turns off the heating restrictions:

1. Open Settings → Applications → Application Management.
2. Select a game (such as Genshin Impact or Call of Duty Mobile).
3. Click on "Game Turbo" and turn off the "Performance Improvement" option.

Hidden engineering menu:

For advanced users, there is a way to forcely limit the clock frequency of the processor:

Enter the dialer in ##4636##


Go to the tab "Battery Information"




Look at the current temperature (normal: 30-40°C in plain)




Go back and select "Usage statistics" → "CPU usage"




You can see which nuclei are overloaded.

💡

If the temperature is above 50°C, and you are not playing or shooting videos, check your smartphone for viruses using Malwarebytes or a built-in scanner in the computer. MIUI Security: Some mining viruses may covertly use the processor.

Emergency cooling: what to do if your smartphone is already hot

If the Redmi Note 8 Pro is unbearably hot (for example, after an hour of playing or shooting a video in the game). 4K), You can act fast, but you can't be bigoted:

The most effective way is to stop the processes:

1. Hold the power button until the off menu appears.
2. Press and hold the "Stop" icon (the option "Reboot in Safe Mode" will appear).
3. Confirm the reboot. Only system applications are running in safe mode, which reduces the load.

⚠️ Warning: If the smartphone warms up quickly again after cooling, check the battery status in the Settings menu → Battery. → Battery condition: If the capacity has fallen below 80% of the original capacity, the battery needs to be replaced, which can cause overheating.

Hardware solutions: from thermal paste to coolers

If software methods don’t work, it’s time to consider physical modifications, and it’s important to understand that some require disassembling the smartphone and may take away warranties (if they still work).

1. Thermopaste replacement

Over time, the factory heat paste between the processor and the heat sink dries up.

• 🧪 Liquid metal (such as Thermal Grizzly Conductonaut) is the best option, but requires accuracy (conducts electricity!).
• 🟦 High temperature paste (e.g. Arctic) MX-6) — safer, but less effective.

Replacement process:

1. Disassemble the smartphone (you need a plastic transmitter and a screwdriver). T3).
2. Clean the old paste with alcohol.
3. Apply the new paste with a thin layer (no more rice grain!).
4. Build the device, check the temperature in AIDA64.

2. Cooling accessories

• 🧊 External cooler with USB-Type-C (for example, Black Shark FunCooler Pro) – reduces the temperature by a small amount of time. 8-12°C in games.
• 📱 Fan case (e.g., fan case, ZMI Fan Cooler Case – less effective but does not require connection.
• 🧲 Magnetic radiator (stick to the back panel) - passive cooling, reduces heating by 3-5°C.

Modification of the shell

For extreme cooling, some users drill holes in a plastic cover or install additional heat pipes.

• ✅ Plus: the temperature can drop by 10-15°C.
• ❌ Cons: loss of leakage, risk of dust, cancellation of warranty.

Refrigeration when charging: why warms up and how to avoid

The Redmi Note 8 Pro is particularly heated when charged and used at the same time (MT6358) The processor is close together and the charger is fast. 18W heat-excretion.

How to reduce heat:

• ⚡ Use the original power supply (not fast charging from other brands).
• 🔌 Charge your smartphone in airplane mode or with the screen off.
• 🔋 Turn off optimized charging in Settings → Battery → Battery settings.
• ☀️ Do not charge in the sun or in a stuffy room (optimal temperature for charging: 10-35°C).

If the smartphone is warm even with the original charger, check:

• 🔌 Cable: Damaged wires can cause short circuits and overheating.
• 🔋 Type-C port: Dust or moisture intrusion worsens contact.
• 📱 Firmware: in some versions MIUI There was a power controller bug (update to the latest version).

Overheating in games: graphics settings and alternative methods

Redmi Note 8 Pro was positioned as a gaming smartphone, but it was not Mali-G76 MC4 Video accelerator warms up a lot at high settings. Here's how to reduce load without losing weight. FPS:

1. Optimal graphics settings (for popular games):

2.Use of Game Bench

The Game Bench app (available on the official website) allows you to:

• 📊 Monitor FPS and real-time temperature.
• 🔍 Compare performance before and after cooling.
• ⚙️ Optimize settings for a specific game.

Alternative methods:

• 🎮 Use a gamepad: holding a smartphone in your hands increases its heating 2-3°C.
• ⏸️ Take breaks: every 20-25 minutes of play let the smartphone rest 5 minute.
• 🔄 Cool between sessions: Put your smartphone on a metal surface or use a cooler.

💡

The most common mistake gamers make is to play with a connected charge. 15-20°C and reduces battery life.

When overheating is a reason for repairs

If neither method worked and the Redmi Note 8 Pro is still overheating, the problem could be hardware.

• 🔥 Smartphone Heats Up to 50°C+ In simple (without games and charging).
• 🔋 The battery is discharged for 2-3 hourly with minimum load.
• 📉 Performance drops sharply even after reboot.
• 🚨 A warning appears: "Temperature is too high" in normal use.

Possible malfunctions:

Cost of repairs in service centers:

• 🔧 Replacement of thermopaste: 800-1500 ₽.
• 🔋 Battery replacement: 1500-2500 ₽ (original).
• 📱 Diagnosis of the motherboard: 500-1000 ₽.

⚠️ Warning: If you notice that your smartphone has started to heat up more after falling or getting moisture, do not try to cool it yourself.In this case, overheating may be associated with a short circuit on the board, and urgent diagnosis is required.
