Cold weather and phone batteries

The effect of low temperatures on smartphone batteries, especially those based on lithium-ion batteries, leads to a slowdown in chemical reactions and increased internal resistance. This results in a temporary decrease in the battery's ability to supply energy and can cause the device to shut down suddenly despite still having a charge. Companies like Apple and Samsung emphasize that using the phone within temperatures ranging from 0 to 35 degrees Celsius is optimal. Continuous exposure to extreme cold can impair battery performance and shorten its lifespan, particularly with repeated exposure. To protect your phone during winter, it is advisable to minimize exposure to the cold by keeping it in an inner pocket, avoid charging it in cold environments directly, and allow it to warm up gradually before charging or use. It is also recommended to check the battery if the device frequently shuts off or experiences rapid discharge, as prolonged exposure to cold can cause permanent performance deterioration.
