Xiaomi Redmi 8 Pro overheats: how to cool quickly and prevent heating

Xiaomi Redmi 8 Pro is a popular smartphone with a powerful Snapdragon 665 processor and 48-megapixel camera, but many users experience its overheating, especially when playing long games, shooting 4K video or fast charging. In this article, we will analyze the causes of heating, emergency cooling and prevention methods – from software settings to hardware solutions.

It's important to understand that overheating doesn't always mean that you're breaking, for example, when you charge a case to 40-45°C, it's the norm for the Redmi 8 Pro. But if you heat up to 50°C+ in standby mode or shut down from overheating, that's a reason to take action. We've put together proven methods to help bring the temperature down without harming the device.

Why Xiaomi Redmi 8 Pro is overheating: the main reasons

Overheating Redmi 8 Pro can be caused by both software and hardware factors, and consider the most common causes, starting with the most innocuous:

1. Intense CPU load: Games (PUBG Mobile, Genshin Impact), video rendering or multitasking make the Snapdragon 665 run at its limit. This chipset is prone to heat due to the 11nm architecture, especially under prolonged loads. Temperatures can rise to 60-70°C in the area of the camera and processor.

2: Fast charging. Redmi 8 Pro supports Quick Charge 3.0 (18W), but not all chargers are equally safe. Cheap cables or power supplies without protection can cause the battery to overheat. Normal charging temperature is up to 40°C, if higher, this is a risk of battery degradation.

3. Background processes and viruses: Some applications (especially those with ads) consume resources in the background, for example, Facebook or TikTok can keep the processor loaded by 30-50% even when you are not using them, and viruses and mining scripts also provoke heating.

4. Bad heat sink. Over time, the heat paste between the processor and the housing dries up, and the dust clogs the vents (if the case is dense), which worsens heat transfer, and the temperature rises even on normal tasks.

5. Battery or board malfunctions: A bloated battery, damaged contacts or problems with the power controller can cause critical overheating to 80°C+ with spontaneous shutdown, in which case diagnostics are required at the service center.

• 🔥 Games and heavy applications – load at GPU/CPU to 100%
• ⚡ Unqualified charging – cheap cables, power higher 18W
• 🦠 Viruses and background processes – hidden mining, advertising SDK
• 🌡️ Poor thermal conductivity - drying of thermopaste, dust in connectors
• ⚠️ Hardware malfunctions - bloated battery, damaged board

⚠️ Warning: If the Redmi 8 Pro heats up to 50°C+ in standby mode (no games or charging) is a sign of malfunction. Back up your data immediately and contact the service. Further use may cause the battery to catch fire.

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

If the Xiaomi Redmi 8 Pro is heated to an unacceptable temperature (for example, after an hour of playing or shooting a video), use these methods to quickly cool down:

1. Turn off the phone on the 10-15 for minutes. A complete power outage will allow the processor and battery to cool naturally. Don't use "reboot" - it does not have the effect of completely turning off.

2. Remove the case and put the phone on a cold surface. Metal or ceramic surface (such as a countertop or window sill) will help to remove heat. Do not put the phone in the refrigerator - a sharp temperature drop can cause condensation inside the case!

3. Use an external cooler. Direct the airflow from the fan or air conditioner to the back of the phone. You can buy a special cooler for smartphones with USB- connection (costs from 300 rubles).

4. Turn off charging. If the phone is warming up while charging, disconnect the cable. Quick Charge 3.0 charges the battery more than usual. Go to 10W charging (a standard unit from Redmi Note) if the problem recurs.

5. Reduce the brightness of the screen and turn off unnecessary functions. High brightness settings, Always-On Display, NFC, Bluetooth and GPS increase the load on the processor. Disable them through the notification panel.

⚠️ Warning: Don't use ice or cold water to cool you! This can short circuit because of condensation. Also don't blow into the phone's connectors, because dust can get in and degrade the heat sink.

Programming methods of reducing temperature

If the Redmi 8 Pro is warming up for no apparent reason, the problem may lie in the system settings or background processes.

1. Close the background applications. In MIUI, many programs continue to run in the background to close them:

1. Open Recent Apps (swipe up with a delay).
2. Swipe your finger upwards through each app to close.
3. To clean completely, click the "Close Everything" icon (cross or basket).

2. Disable auto-run of unnecessary programs. Many applications start automatically when the phone is turned on.

1. Go to Settings → Applications → Application Management → Autorun.
2. Turn off auto-run for social media, instant messengers, and games.

3. Activate Performance Mode. MIUI has a built-in mode that limits background processes:

1. Open Settings → Battery and Performance → Performance mode.
2. Select "Balanced" or "Saving Charge".

4. Update the firmware. Newer versions of MIUI often fix bugs related to overheating.

Settings → About the phone → System update

5 Use temperature monitoring applications: Utilities like CPU Monitor or AIDA64 show the temperature of the processor, battery and other components in real time, which will help to identify which application or process is causing the heating.

Hardware solutions: when software methods do not help

If the Redmi 8 Pro is warming up even after optimizing the settings, the problem could be in the hardware.

Replace thermopaste: Over time, the factory thermopaste between the processor and the housing dries up, worsening the heat sink. Replacing the thermopaste in the service center costs 500-1000 rubles and can reduce the temperature by 5-10 ° C. You will need to replace it yourself:

• 🔧 Screwdriver T3 and T5 for disassembly
• 🧴 Thermopaste Arctic MX-4 or KPT-8
• 🧹 Alcohol and lilaless wipe for cleaning

2 Dust and pile in the connectors and under the back cover impair heat transfer.

1. Turn off the phone and remove it. SIM-map.
2. Gently blow the connectors with compressed air (a canister for cleaning equipment).
3. Wipe the body with a microfiber cloth.

Replacement of the battery: If the battery is swelling or has lost capacity, it may warm up even in standby mode.

• 🔋 Phone discharges quickly (less than 4 hours of operation)
• 🌡️ Heating of the housing in the area of the battery without load
• 💥 Bloating of the back cover (seen by the gaps)

4. Use of a cooling case: Cases with built-in heat pipes or aluminum inserts help to remove heat.

• 📱 Baseus Magnetic Cooling Case (Magnetic Cooling Case)
• 🧊 Black Shark Cooling Backplate (for gamers)

⚠️ Warning: If you notice a bloated battery, stop using your phone immediately! The bloated battery may ignite when heated or mechanically exposed. Contact the service for replacement.

Cooling during games: settings for gamers

Xiaomi Redmi 8 Pro often overheats in games due to a weak cooling system.To lower the temperature without losing performance, follow these tips:

1. Lower your graphical settings in games. In most games (e.g. PUBG Mobile or Call of Duty), you can choose:

• 🎮 Graphics quality: Balanced or Low
• 🔄 Frame rate: 30 FPS instead of 60 FPS
• 🌿 Effects: Turn off shadows and antialiasing

2.Use Game Turbo. MIUI has a built-in game mode that optimizes performance:

1. Open Settings → Special features → Game Turbo
2. Turn on the option and add the game to the list.
3. Activate “Performance Optimization” and “CPU Cooling”.

3. Limit background processes. Before starting the game, close all unnecessary applications and disable:

• 📶 Mobile data (if you play over Wi-Fi)
• 📍 GPS (unless the game requires geolocation)
• 🔊 Bluetooth and NFC

4. Use an external gamepad. Touching the screen heats it up more than physical buttons. Connect the gamepad over Bluetooth (e.g., Xiaomi Game Controller) for comfortable play without overheating.

💡

If the game heats up your phone, try turning on the plane mode before launch, which will turn off background network activity and reduce the load on the processor.

How to Prevent Overheating in the Future: Prevention

To Xiaomi Redmi 8 Pro does not warm up at all, follow these rules:

1. Avoid direct sunlight. Don't leave your phone on the windowsill or in your car in the summer. Temperatures above 35°C accelerate battery degradation.

2. Use original accessories. Xiaomi chargers and cables are certified and less warmed, and cheap ones can cause overheating or even short circuiting.

3. Update apps regularly. Developers often release patches that optimize resource consumption. Update games and software through Google Play.

4. Do not use your phone while charging. Simultaneous play and charging increase the load on the battery by 2-3 times. If you need to urgently charge, put the phone in flight mode.

5. Check your temperature once a month. Use apps like AIDA64 to track your performance.

• 📱 Processor: up to 45°C in plain, up to 65°C under load
• 🔋 Battery: up to 40°C when charging, up to 35°C in operation

💡

Regular cleaning of the cache and updating the firmware reduce the risk of overheating by 30-40%.

What to do if nothing helps: diagnosis and service

If the Redmi 8 Pro continues to warm up despite all measures, the problem may be a hardware malfunction.

1. Diagnose. Xiaomi service centers have special equipment to check:

• 🔋 Battery state (bloating, capacity)
• 🖥️ Processor and motherboard work
• 🌡️ Efficiency of the cooling system

2. Check warranty. If the phone was purchased less than a year ago, repairs can be free. Check this by device number (IMEI) on Xiaomi's website.

3. Contact an authorized service. Don't trust repairs to informal workshops, it may take away your warranty.
