Winter is here, bringing low temperatures that can affect the performance and lifespan of batteries in mobile phones, GPS systems, and other devices. Lithium batteries discharge quickly in sub-zero temperatures, and their performance starts to degrade as temperatures drop below -4ºC.
This issue becomes even more critical if these devices are part of your navigation system or emergency contact method. Therefore, it’s essential to take precautions to mitigate this situation.
Many brands recommend using devices within a temperature range of 0ºC to 30ºC, as temperatures below -10ºC significantly impact battery performance. Some brands even discourage using certain devices below -20ºC, warning that the battery will fail completely.
In certain environments, especially in high-altitude mountains, temperatures can easily drop below -20ºC. This is an important factor to consider when planning an expedition or even a simple hike.
Tips to Avoid Running Out of Battery
- Avoid exposing devices to extreme temperatures: Carry your devices close to your body to keep them warm.
- Do not place devices on cold or icy surfaces.
- Download offline maps: Offline maps allow you to use your phone in airplane mode or in areas without network coverage, helping to conserve battery life.
- If your phone gets too cold: The battery charge will drop, and the device may shut down. If this happens, warm the device by keeping it close to your body. Once the battery warms up, the phone should power back on.
- If you need to charge a cold battery: Wait until it warms up. Charging a battery that has shut down due to cold temperatures will be ineffective and can damage the battery.
- Carry extra batteries.
- Lower screen brightness: A bright screen consumes a significant amount of your phone’s battery.
Important Note:
High and extremely high temperatures also dramatically affect battery performance and lifespan. In some cases, they can even cause devices to shut down.
