- Charging your phone overnight kills the battery
Your smartphone is smarter than you think. Once it is fully juiced up, your phone knows that it doesn’t need the power supply anymore, which means the battery isn’t being used at all. However, that doesn’t mean you should charge your phone all night, every single night. You wouldn’t be filling a cup with water if it is already full, would you? But your battery life will last longer if you keep your phone charged between 40% and 80%.
