Why does my phone get so hot?
Heat in smartphones comes from multiple sources and it is important to understand them to avoid damage:
- Processor (CPU) working at maximum performance: Demanding games, augmented reality apps, video editing, and background processes can raise internal temperatures.
- Battery: : Rapid charging, the use of non-original chargers, faulty cables or a battery in poor condition cause intense heating, especially during charging.
- Direct sunlight or hot environmentsLeaving your phone in the sun (on the terrace, at the beach, in the car) can increase the internal temperature very quickly.
- Poorly optimized configurations: : Maximum screen brightness, excessive widgets, animated backgrounds, or outdated apps consume resources and raise the temperature.
- Malware or untrustworthy appsA virus or malicious app can overload the CPU, pushing the phone to dangerous limits.
- Wireless or fast charging: Both technologies produce extra heat, especially if the phone is already hot from use or the external environment.
Heat may come from the battery, processor (CPU/GPU), or charging port.Identifying the source helps to apply the most appropriate solution.
What is the ideal and maximum safe temperature for a mobile phone?
Most manufacturers, such as Apple and Samsung, state that Mobile phones work optimally between 16°C and 25°CUnder normal conditions, the internal temperature can hover around 20-30°C, although during charging, gaming, or intensive use, it can easily reach 35-40°C.
It is not recommended that the mobile phone constantly exceeds 35-40°CIf it reaches 45°C, it's time to act. Above 50°C, some smartphones activate automatic protection mechanisms, even shutting down to prevent permanent damage.
- Between 0°C and 35°C: completely safe range, no risks to components or battery.
- 36 ° C to 43 ° C: This remains normal in hot environments or during periods of very intensive use.
- From 45°C: The battery begins to degrade and the lifespan of the internal components may be drastically reduced.
- Above 50°C: Risk of shutdown, permanent damage and even risk of accident if the battery is defective.
Some gaming phones tolerate slightly higher temperatures, but these are always exceptional and short-lived situations. Charging your phone at temperatures above 45°C can degrade the battery quickly and cause serious failures..
How to know the temperature of your mobile phone

- Decreased performance: The processor limits its speed (throttling), making everything run slower and the experience frustrating.
- Camera, sensors or screen failure: Heat can cause the camera to turn off, reduce brightness, or even display error alerts on critical system apps.
- Data loss or corruption: Internal memory may become unstable if the device is too hot.
- Physical danger: A defective battery exposed to high temperatures can expand, deform, or in extreme cases, catch fire.
Preventing overheating is key to extending the lifespan of your smartphone. and avoid unpleasant surprises or costly repairs.
What to do if your smartphone overheats?
Notice your phone is getting very hot? Act quickly. following these steps to cool it safely:
- Turn off the phone If the temperature is abnormally high or you notice a drop in performance, shutting it down will stop all heat-generating processes.
- Take your phone to a cool, dry place: Avoid leaving it in the sun, inside a closed car or in hot environments.
- Remove the case or coverCases often act as an insulator, hindering heat dissipation. Removing them allows the device to "breathe."
- Do not charge it until it returns to normal temperature.: Charging generates additional heat and can aggravate the problem.
- Close all applications or activate airplane mode: Limits background processes so the processor and battery can cool down.
- Do not put it in the refrigerator or freezer: Sudden temperature changes produce internal condensation, which can irreparably damage electronic components.
- If you have a fan or air conditioner nearbyPlace your phone in front of you for a few minutes after closing everything and removing the case. This helps cool it gently and safely.
Remember: Cooling your phone naturally and gradually is always the best option.. Forcing or exposing it to extreme cold can be dangerous.
Practical tips to avoid overheating
- Close background apps: Keeping too many apps open consumes CPU and memory, increasing heat. Do this regularly from the recent apps viewer or in advanced options (Developer options → Limit background processes).
- Disable unnecessary functions: GPS, Bluetooth, WiFi and NFC generate heat if left on unnecessarily.
- Check out the most demanding apps and games: 3D games, camera apps, GPS navigation, and video streaming are often the main culprits of your phone burning up.
- Adjust the screen brightness: Maximum brightness significantly increases power consumption and temperature. Use automatic brightness or adjust it manually based on the environment.
- Update the software: Updates fix bugs and improve power management, reducing heat produced by the hardware.
- Do not use your phone while charging.: Avoid playing games, recording videos, or performing heavy tasks while charging.
- Charge on smooth and ventilated surfacesForget the bed, the couch, or under a pillow. Choose tables or flat surfaces.
- Use the original charger: Low-quality chargers or those with incorrect voltages can cause overheating and permanently damage the battery.
- Control storageA phone full of unnecessary files or apps can strain memory and therefore heat up the device.
