The batteries installed in modern smartphones are based on lithium polymer or lithium ion technology. They differ from each other in the type of electrolyte used: solid or liquid. And the characteristics of these batteries are connected with the rapid discharge of mobile phones in the cold.

Of the two types of smartphone batteries, lithium polymer ones tolerate cold better. But they still discharge in the cold. When the smartphone is cooled to 0 degrees Celsius, it loses 20-40% of its battery capacity. Fortunately, its capacity is restored when it returns to normal temperature.

In addition, the cold resistance of the smartphone depends on several factors. These are the thermal conductivity of the case material (the metal cools faster), the battery capacity (the larger it is, the slower the charge is lost), the presence of a cover (which serves as additional protection against cold), the time spent cold.

If you’re leaving home for a long time in the winter, the following tips can help you keep your battery charged. Put the smartphone in the inner pockets, that is, closer to the body; remove the device only if absolutely necessary; talk on the phone as little as possible; close apps and services you don’t use; dim the screen if you are using navigation.

Also, do not charge the device immediately after returning from the cold. Wait until the smartphone body reaches room temperature.
