Why You Shouldn't Charge Your Phone to 100%?

Modern smartphones use lithium-ion batteries that naturally degrade over time. While charging your phone to 100% occasionally is not harmful, doing so every day can accelerate battery wear by keeping the battery at a high state of charge, where chemical stress is greatest.

Battery experts and smartphone manufacturers recommend maintaining a charge between about 20% and 80% for everyday use whenever practical. Understanding how batteries age—and adopting a few simple charging habits—can help extend your phone"s battery lifespan and maintain its performance for longer.
