'Wearing' warm clothes to increase battery life in cold weather

According to experts, when the ambient temperature drops below about 0°C, the performance and energy storage capacity of lithium-ion batteries in smartphones or laptops can be significantly affected. Experimental evidence shows that keeping warm – for example by wearing a thick coat or warm jacket over it – helps keep the body and ambient temperatures more stable, thereby helping the battery work in more ideal conditions.

Solid-state batteries have higher energy density and safety than lithium-ion batteries.

“When the battery is operating in a cold environment, the internal resistance of the battery increases and leads to a limited charging and discharging capacity, and the device may even suddenly shut down even though there is still battery,” said an expert. Therefore, keeping the device and the user warmer is considered an indirect way to extend battery life and ensure performance.

In actual use, users who are experiencing winter or using the phone outdoors in the cold should be careful not to expose the device directly to extremely cold air for a long time. For example, placing the phone in a coat pocket, near a human body heat source or putting it in a warm bag is better to avoid rapid battery drain or reduced performance.

In addition, storing the device when not in use also requires compliance with appropriate temperature conditions. If the device is left in a place that is too cold or quickly changes from cold to hot, the battery may be permanently damaged. Experts recommend leaving the device at the ideal room temperature before using or charging to reduce the negative effects of temperature.
