On hot sunny days, phones are often easily overheated when used continuously to play games, watch videos, make video calls or film outdoors.
When the temperature rises, many devices will automatically reduce screen brightness, reduce performance or charge slowly to protect internal components. This is also the reason why many users are starting to look for external cooling units for phones.
Currently, popular phone cooling accessories include mini fans mounted on the back of the phone and coolant cooling models using semiconductor technology.
Mini fans have the advantage of being cheap, easy to use and suitable for common needs such as watching videos, surfing social networks or video calling for long periods of time.
Meanwhile, cooling fans have a faster cooling ability, often used when playing heavy games, livestreaming or continuously filming outdoors.
However, according to phone manufacturers, users need to understand that heat dissipation is just a device to help reduce the surface temperature of the phone, and cannot thoroughly handle the cause of the phone overheating.
If the phone is frequently abnormally hot due to battery degradation, using it while charging, or using poor quality charging accessories, installing a cooling fan only helps reduce heat temporarily.
Users should also not let their phones directly exposed to sunlight for long periods or put them in the car in the sun because high temperatures can affect the battery and internal components.
Some notes when using phone cooling fans:
- Do not use a cooling device that is too strong in a high-humidity environment to avoid water vapor stagnation inside the machine.
- Remove the back cover when the phone is too hot to increase heat dissipation.
- Limit both charging and playing games or livestreaming.
- Prioritize using accessories with clear origins to avoid the risk of electrical short circuits.
- Turn off backward-based applications to reduce device load.
In addition to using a cooling fan, users should reduce screen brightness, limit using phones outdoors in hot sun and let the device rest after a long period of continuous operation.
If the phone shows abnormal hot flashing signs, the battery drains quickly, or the back of the device is slightly bulging, users should take the device for inspection to avoid the risk of damage or battery explosion.
