Most people charge their phones to 100% every night without thinking twice. Full battery means maximum usage time, right? But lithium-ion batteries (the type in every iPhone and Android phone) actually degrade faster when they spend hours at full charge or completely drained.
Your phone already has built-in settings designed to protect battery health by limiting charging, but most people never enable them or don't even know they exist. If you plan to keep your phone for more than two years, turning on these features is one of the simplest ways to extend your phone's battery lifespan.
