Charge limiting to extend lithium ion battery life

The article discusses the importance of charge limiting to extend the lifespan of lithium-ion batteries in electronic devices. It highlights factors affecting battery life such as temperature, charging speed, and the number of charge cycles. By maintaining batteries at cool temperatures and limiting the charge between 30% and 80%, users can prolong battery health, save money, and reduce e-waste. The piece provides guidance on implementing charge limits for phones and laptops, emphasizing the benefits of keeping a buffer of available capacity within the battery. For iPhones, Apple offers built-in solutions, while Android users may need to explore manufacturer-specific options or third-party apps with caution. The article also touches on battery optimization for electric vehicles and provides references for further reading on battery maintenance. Overall, the practice of charge limiting is recommended to enhance battery longevity and reduce environmental impact.
