Charging your cell phone battery overnight has become a common habit, but it might not be the best for long-term battery life. According to experts, consistently charging to 100% can cause chemical aging and lead to faster deterioration of the battery.
The problem lies in the high voltage that occurs when charging to 100%, which causes damage to the product over time. If you frequently charge your phone to 100%, your battery will degrade around 10-15% faster than if you charged it to a lower percentage, such as 90%.
However, this doesn’t mean you should never charge your phone to 100%. Experts say that if you have a mission-critical day and need more electricity, charging to 100% might be necessary. But for everyday use, keeping the battery charged between 20-80% is ideal.
Additionally, experts recommend avoiding extreme temperatures, dropping the battery to 0%, and using fast chargers too often. Keeping your phone in room temperature environments and opting for slow charging can help prolong the battery’s lifespan.
Most smartphones allow you to check your battery health in settings. If your battery health is below 80%, it’s recommended to replace it. By following these simple tips, you can keep your phone battery healthy throughout its lifetime.
