According to Battery University, an authoritative resource on battery technologies, maintaining a charge level between 20% and 80% helps extend the overall lifespan of lithium-ion batteries. Charging to 100% can place stress on the battery and accelerate its degradation over time.
The underlying reasons for avoiding continuous full charges involve the chemistry of lithium-ion batteries. When a battery charge reaches 100%, the voltage increases, which can produce heat and lead to chemical reactions that wear out the battery’s components. This phenomenon is called “voltage stress,” where higher voltages accelerate the deterioration of the battery’s internal structure.
In more technical terms, the process involves the formation of lithium plating and electrolyte decomposition. Lithium plating occurs when lithium metal builds up on the anode, while electrolyte decomposition produces gas bubbles that can cause swelling. These reactions can eventually lead to capacity loss and reduced battery efficiency.
Specific actions contribute to this issue. Regularly charging your phone overnight, for example, leads to prolonged periods at full charge. Additionally, leaving your phone plugged in even after reaching 100% keeps the battery in a high-stress state. Thus, it matters significantly how often and how long the device stays charged at full capacity.
