Does the phone use 40 degree sunshine to cause harm, even a fire accident?


In recent days, the North is suffering from a long-lasting intense heat, though sometimes there are scattered rains but still not enough to drown out the burning sun. Midday outdoor temperatures can reach more than 40 degrees, making everyone uncomfortable and tired of the extreme hardship.

If you think it's all the most worrisome things, then it's wrong, because your everyday non-intimate phones are also "troubled" no less than the owner when exposed to this sunshine nightmare!

Overload temperature: Top worry of technology items

Temperature is one of the leading factors calculated in relation to durability when using technology devices in general. If the previous day, this worry just waiting for the execution of gamers with super high-end computer systems used to load heavy tasks, nowadays, smartphones in general are no exception.

With heat, the temperature increase while using is normal, especially when turning on many apps or consuming a lot of power when using it for a long time. However, the excessive temperature allowed is another story, it is entirely possible to leave unreasonable damage, the money is not always good. The obvious consequences of thermal overload are the speed of decline, battery life is damaged.

Whether due to objective reasons (hot sun, high air temperature) or subjective (using the machine for a long time), they always leave potential consequences and risks that users need to know clearly. to prevent kidney damage.

Surely this is not a smart action in the Northern weather these days.

How does thermal overload occur, how to handle it?

Most processor chips in smartphones have been recognized by experts, optimized designs to minimize the heat impact when encountered. In theory, they are fully tolerant of the highest heat levels that smartphones themselves have produced during use – synonymous with heavy and long-lasting applications, all still in the calculation and gender. original term. At that time, the chip's speed will partly reduce itself as a self-activated safety mechanism, which helps to cool down and "recover" to avoid the risk of failure.

However, that does not include factors that exert additional heat from the outside, especially hot sun or other heat generating environments. If the danger limit is still violated and there are no signs of remission, many consequences will occur: Warning occurs, the device will automatically power off or sometimes battery explosion. At that time, there will be 2 most pleasant components to damage: Smartphone batteries and processor chips.

The iPhone's default alert appears when the phone detects itself too hot.

The structure of popular Li-ion batteries in smartphones today is quite durable and easy to use and flexible to use. However, nothing is forever, the first drawback of Li-ion batteries is that the temperature rises with reduced life expectancy. In other words, the more battery a battery is, the easier it is to generate excess heat when used for a long time.

In addition, the available properties of Li-ion batteries are sensitive to temperatures that are too hot and too cold. Summer days with temperatures higher than 30 degrees Celsius are more than enough to break the ideal safety level for batteries, which is harmful and reduces life expectancy. All repeat and interact with each other as a vicious cycle, which is easy to cause great consequences if maintained for a long time. Likewise, the smartphone's processor chip is not interested in being constantly hit by the heat, while there is no cooling fan like a computer.

How to overcome and prevent

In addition to keeping your smartphone in an ideal cool environment, keep an eye on unusual signs of overheating or slowness during use.

Currently, many smartphones already have automatic thermal overload warning function, or the iPhone can see the life and battery level in Settings, and other brands need to download additional apps for self-monitoring. Also, avoid oppressing the smartphoone inside a thick case with a heavy case, using too many heavy apps for a long time …

For added certainty, go to a reputable store to do an overall smartphone inspection service after a period of use. If not, the risk of one day of battery failure and fire will still be permanent, who knows when it's hot because it's too hot.
