Batteries drain much faster in the cold. The reason for this is the electrochemical process inside the device
Smartphone battery in the cold: ions become slower
If the battery drains faster due to low temperatures, this is due to the reduced movement of the ions inside the device.
- They are located in the so-called electrolyte. This is a chemical compound that enables the ions to move and thus generate energy.
- Temperatures of around 20°C are required for optimum performance. If the temperature drops to 10°C or lower, the electrolyte becomes increasingly sluggish. This also increases the internal resistance of the battery
- As a result, the ions can no longer move effectively and the energy is no longer transferred optimally. The colder it is, the faster your smartphone battery drains due to the reduced ion movement.
- One problem caused by the cold can be a possible deep discharge of the battery. Modern smartphones have a fuse that automatically switches off the device beforehand.
- Tip: If you are traveling in particularly cold areas, carry your smartphone close to your body or use a phone case. This means less heat is lost, which protects the battery.
