Batteries work by the movement of ions (charged particles) that are generated due to the chemical reaction inside them. At full charge, the ions pack tightly and exert more pressure inside the battery. This causes the discharge rate to increase and reduce the life over time. So, the Lithium-ion battery of a laptop works best if you keep it charged between 30 to 80 %. You can limit the battery charge by enabling the battery optimization features in your laptop. In this guide, we have provided the method to set the charging threshold for different laptops.
