The 100% Charge Myth: How to Keep Your Phone Battery Healthier Longer
Charging to 100% overnight can slowly shorten battery life because it keeps the cell at high voltage, but the impact is gradual and modern phones are durable. For best longevity, aim for about 20–80% charge, avoid excessive heat, and prefer slower chargers; don’t regularly let the battery drop to 0%. Check battery health and replace the battery if it falls below around 80%, and you can charge to 100% when you need longer usage for travel or important days.
