Overheating isn't always a defect. For example, if you charge Quick Charge 3.0 intensively, heating to 40.°C is the norm, but if the phone is hot to the touch in standby mode, or if it turns off with a warning that says "temperature is too high," it's time to intervene. We'll take the cause, from background processes to thermal paste, and give step-by-step instructions with a chequelist widget for emergency cooling.

The Redmi 8 Pro features a metal body that removes heat better than plastic but heats up faster in the sun, and it often warms up the area around the main camera (because of the 64MP module) and the bottom of the screen (there is a chipset).

1. Emergency cooling: what to do right now

If your phone is already burning your hands or showing a temperature warning, follow the algorithm:

• ❄️ Turn off your smartphone for 10-15 minutes. Even when it's off, it will cool faster than when it's in standby mode (background processes continue to load the processor).
• 🔌 Disconnect the charger if the phone is warming up when charging. Using non-original adapters or cables increases heat by 20-30%.
• 📴 Remove the case, especially silicone or thick. The covers block heat transfer, increasing the temperature by 5-10°C.
• 🌬️ Place your phone in front of a fan or air conditioner. The flow of air will speed up cooling by 2-3 times. Don't direct cold air directly into the connectors!

⚠️ Attention: Do not put the Redmi 8 Pro in the refrigerator or freezer! A sharp temperature drop can cause condensation inside the case, which will lead to oxidation of the contacts. Maximum - place it in the shade on a ceramic surface (tile, plate) that removes heat.

After cooling, check the temperature through the app. AIDA64 (The normal values for the Redmi 8 Pro:

• 📱 Processor: up to 45°C in plain, up to 65.°C under load (short term).
• 🔋 Battery: up to 40°C on charging, up to 45°C - critical threshold.

2. Software methods: settings to reduce heating

Most often, the Xiaomi Redmi 8 Pro is heated up by unoptimized software. Start with these steps:

Turn off background activity:

1. Go to Settings → Applications → Permissions → Autorun.
2. Turn off auto-run for all applications except instant messengers and system services.
3. In the Settings section → Battery and performance → Select “Strict Limitations” for Unnecessary Programs.

Limit your productivity:

Redmi 8 Pro has a hidden restriction option CPU, which reduces heat by 15-20%:

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Back to Settings → Additionally. → For developers.
3. Find the item “Limit background processes” and select “Maximum 2 processes”.
4. Turn off "Windows animation" and "transition animation" - this will reduce the load on the GPU.

💡

If you play heavy games (such as Call of Duty Mobile), turn on Low Quality mode in your graphics settings and limit it. FPS up to 30-40 fps This will reduce the temperature of the processor by 10-15°C.

Update the firmware:

Old versions. MIUI Redmi 8 Pro had temperature control bugs. check updates:

1. Settings → About the phone → System update.
2. If newer firmware is available MIUI 12.5 - Install it. In the latest versions, the Snapdragon 665 cores are optimized.

3. Hardware causes of overheating: what to check

If the software methods didn't work, the problem could be the hardware. Here are the typical reasons for the Redmi 8 Pro:

⚠️ Warning: If the Redmi 8 Pro case is swelling (seen by the gap between the screen and the frame) - immediately turn off the phone and do not use it! The bloated battery may ignite. Take the device to the service for battery recycling.

How to check the battery:

1. Install the AccuBattery app.
2. Look at the battery health parameter. If it's below 80 percent, the battery is worn out.
3. Check "Temperature on Charging." Normal to 40.°C. If higher, the battery has degraded.

4. Cooling in games: gamer life hacks

Xiaomi Redmi 8 Pro is not positioned as a gaming smartphone, but many use it for the sake of the game. PUBG Mobile, Genshin Impact or Free Fire: For long sessions, temperatures can reach 70-80°C, which leads to trottling (forced performance decline). Here's how to avoid it:

Use the game mode:

V MIUI There is a built-in Game Turbo that optimizes resources:

1. Open Settings → Special features → Game Turbo
2. Turn on the option and add the game to the list.
3. Activate the "Cooling" function CPU" and “Limitation FPS".

External coolers:

For the Redmi 8 Pro, you can:

• 🎮 Fan cooler (like Black Shark FunCooler Pro) fastened to the back and lowered the temperature by 10-15°C.
• ❄️ Passive radiator (aluminum plate with thermal paste) cheap solution (~500 ₽), less effective.
• 🧊 A cooler-powered gamepad (like a ventilated Razer Kishi) is expensive but reduces heat by 20%.

⚠️ NOTE: Do not use liquid cooling (e.g. liquid metal thermopaste) without experience! if applied incorrectly, it can close contacts on the Redmi 8 Pro motherboard.

💡

The most effective way to cool down games is the combination of Game Turbo + It's an external cooler, and it drops the temperature to 50 to 55.°C even in the hard games.

5. Charging without overheating: rules and errors

The Redmi 8 Pro supports Quick Charge 3.0 (18W), but fast charging always heats the phone up more.

Use the original adapter:

Non-original chargers (especially with AliExpress) can produce unstable voltages, which leads to:

• 🔥 Heating the battery to 50–60°C.
• 📉 Rapid battery degradation (capacity loss).
• ⚡ Short-circuit risk.

The original Xiaomi adapter has a marking MDY-11-ED (18 watts. If you have another, replace it.

Charge in a cool place:

Don’t leave the Redmi 8 Pro on charge:

• 🚫 In the sun (even through the window).
• 🛏️ Under a pillow or blanket.
• 📦 In a closed case.

The ideal temperature for charging is 15–25°C. Pri. >30°C battery wears out 2 times faster.

Turn off the charger by 80%:

In the settings of Redmi 8 Pro there is an option “Optimized charging” (Settings) → Battery → Battery settings. It limits the charge to 80 percent, which is:

• ✅ Reduces battery heat.
• ✅ Increases its service life by 30-40%.

6 Radical measures: when nothing helps

If the Redmi 8 Pro is warming up even after all the manipulations, there are extreme measures:

Reset to factory settings:

Sometimes, system errors or viruses cause overheating, and a reset will delete all the data, but it can solve the problem.

1. Make a backup (Settings → About Phone → Backup).
2. Go to Settings → Additional → Resetting settings.
3. Select "Delete all data" and confirm.

Thermopaste replacement:

In the Redmi 8 Pro, the heatpast dries over time, especially if the phone has been warmed frequently. Self-replacement is possible, but requires care:

• 🛠️ Disassemble the phone (need a mediator and a cross screwdriver).
• 🧴 Remove the old paste with alcohol and cotton swab.
• 🎨 Apply a new one (such as Arctic) MX-4 or KPT-8).
• ⚠️ Don’t use too much – the excess can get to other components.

Installation of custom firmware:

Stock-stock MIUI Alternative firmware (like Pixel Experience or LineageOS) may be better at controlling temperature:

• ⚠️ Guarantee burns out.
• ⚠️ The risk of “bricking” the phone.
• ✅ Potential productivity gains and reduced heating.

7.Prevention: How to prevent overheating in the future

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

• 🌡️ Control the temperature with the help of AIDA64 or CPU Monitor. >50°C. Let the phone rest.
• 🔄 Clean the cache regularly (Settings) → Warehouse → Clear the cache. The cache that's clogged is loading the processor.
• ☀️ Avoid direct sunlight. Even in standby mode, the phone can heat up to 60 in the sun.°C.
• 📲 Do not use your phone while charging for games or videos, which increases your heat by 30 to 50%.
• 🔋 Calibrate the battery every 3 months: discharge to 0%, then charge to 100% without interruptions.

⚠️ Warning: If you play or edit video frequently, consider buying an external powerbank to play with the charging turned off, reducing heat.
