Proper charging and use of your smartphone during hot weather is critical to the safe and stable operation of your device. Violation of the basic principles of proper handling of a smartphone in the heat, often leads to malfunctions and reduced performance.
What happens to the battery at high temperature
Smartphone batteries work thanks to the chemical processes that take place in them.
Inside the accumulator there are two electrodes, the environment of which is filled with a conductive electrolyte. During the operation of the smartphone, lithium ions move from the anode to the cathode, and vice versa while charging the battery. The cathode and anode are separated from each other by a special jumper that prevents them from touching each other. If for some reason the anode and cathode are in contact, heat is generated and the battery heats up.
When heated, the electrolyte starts a chemical reaction and gas is released, releasing even more heat. This effect is called “thermal runaway of the battery” and can lead to product fire.
An increase in the temperature of the device during active work and the launch of heavy applications does not yet mean that it is overheating. When running games or watching high-definition videos on a smartphone or tablet, the CPU temperature easily reaches +50 °C. Under heavy load, the processor is able to heat up to 90 ° C, while the device may slightly slow down and turn off.
How to use
The main factor when choosing a cover in the summer should be the accessibility of the ventilation holes. First of all, the cover should not harm the phone, and only then perform protective and design functions.
Contrary to popular belief that the case reduces the possibility of cooling the smartphone, this is far from the case. Developers of all well-known brands produce cases for their devices exactly duplicating the ventilation openings of the case of each model.
In order to prevent your smartphone from overheating when using a case, it is enough to refrain from using incompatible products.
As for the material, everything is personal and depends on the preferences of the buyer.
Exposure to sunlight can quickly heat up both the electronics of the device and its battery.
It is important not to leave your smartphone under the scorching sun, neither in the car nor in the open air.
Mobile games require significant calculations from the processor and graphics core of the smartphone, which leads to a sharp heating of the device. In particularly demanding games, temperatures can easily reach 70 and even 80 °C.
In addition to heating the device, mobile games consume a lot of power, causing the battery to drain quickly. Recharging while playing only increases heat dissipation.
To lower the temperature of the device during gaming, you need to reduce the overall power consumption.
This can be done by lowering the brightness of the display, the game settings responsible for the screen resolution, textures and effects.
You should charge your smartphone in rest mode, especially when using fast charging adapters.
Heavy applications like 3D rendering of the environment or video editing can load the smartphone no less than games. In addition to heavy tools, every smartphone runs a ton of other background applications. Accumulating, they are able to load the phone no less than heavyweights. Most of these programs simply do not need to run every time the device is turned on, much less keep them in the background.
To reduce heat and save battery power, you must disable all unused processes that start during device startup.
The heating of a smartphone from a sofa, car seat and any soft surface occurs for the same reasons as heating when putting the device in a closed case. When the vents are blocked, warm air has nowhere to go, and fresh air has nowhere to come from.
The effect of this heating can reach 65-70 °C when the device is at rest.
To prolong the life of a smartphone, it is better to avoid soft surfaces, or to monitor the availability of ventilation holes on the case.
How to refrigerate
When cooling a smartphone, it is always worth considering the reason for its heating. If the phone is heated by the sun and other heat sources, it is enough to protect the device from further exposure and it will soon cool down.
In case of heating due to program load, it is necessary to gradually terminate all active applications and wait a few minutes. When the cause of heating is a damaged battery, you need to turn off the device. If the battery is removable, it must be replaced. If the body of the device is solid and the battery cannot be removed, the smartphone must be returned to a service center or replaced under warranty.
During the cooling process of the device, it does not need to be charged and used, regardless of the reason for heating.
Charging in the heat
To recharge your smartphone in the heat, you need to minimize the risks of overheating the device. If possible, protect the device from the sun, turn off all active applications. If the temperature exceeds 30 °C, you need to replace the quick charge adapters with standard ones.
Due to the increased risk of battery degradation, the charge limit should not exceed 80%, and recharging the device should start from 40%.
