Does the cold weather affect the battery of mobile phones?

In general, most mobile phones currently use lithium-ion batteries. When the temperature is too low, the capacity of ordinary lithium batteries will be attenuated, but it is basically unaffected at 0 degrees Celsius. When it reaches-10 degrees Celsius, the capacity may be only about half, so when the temperature is low, the battery will be charged but cannot be released.

When the temperature drops 1, the available capacity of the battery will drop by about 0.8%, and the capacity of the battery will return to normal after the temperature rises, so in cold weather, especially in the northern region, the temperature often drops to MINUS several degrees or even dozens of degrees. The performance of the battery will become more fragile.

Extended data:

Chargers are divided into direct charging and seat charging. Direct charging converts 220 AC commercial power into 5V DC power supply, which is input to the mobile phone, and the voltage is reduced by the charging circuit of the mobile phone for battery use. Generally, there will be delivery when you buy a mobile phone. The charger is directly connected to the battery and converts the mains electricity into the voltage required by the battery.

You don't need to charge the 12 hour battery when you buy it for the first time, but it's best to fully charge and discharge it for 3~5 hours. Fully charged refers to normal charging to 100%, and fully charged refers to when the mobile phone uses a low battery reminder. Because the battery has to go through the processes of liquid injection, formation, charge and discharge, capacity separation, etc. before leaving the factory, the battery is in an activated state.

Under the condition of normal use and no serious impact, the service life set by mobile phone manufacturers should be 5 years, which may affect the service life of mobile phones in wet and rainy areas. The service life of mobile phone battery is related to the quality and charging times of the battery, which can be charged at least 500 times.
