To help extend battery life and performance, try to keep the battery level between 20% and 80% several times a week instead of using your device for only a short amount of time, and then plugging it in to recharge the battery. Like all batteries, lithium-ion cells age and deteriorate over time and with use. Therefore, battery life may be reduced and you’ll need to charge your battery more frequently. When battery capacity is lower, the battery can’t be charged as much as it used to compared to when it was newer. This will help reduce deterioration in the battery cells. When using your device, make sure the battery regularly drains below 50%. This means you’ll need to charge your battery more often and the overall battery capacity may be lower. The capacity of lithium-ion cells is reduced after a certain number of times the battery is charged and then discharged. These batteries charge quickly, discharge at a steady rate, and they have high-energy density that allows for small cell sizes in batteries.īy understanding a little about lithium-ion batteries, you can help maximize your battery life and the overall longevity of the battery in your device: Lithium-ion batteries are the most common type of battery used in today’s mobile devices-including laptops and tablets.
