Is It Bad To Leave Your Phone Charging Overnight? | ZONSAN

2023-01-12 It is generally safe to leave your phone charging overnight. Modern smartphones are designed to prevent overcharging, which can cause damage to the battery. Most smartphones will stop charging once the battery is fully charged, so there is no need to unplug the phone once it reaches 100%.



However, leaving your phone charging overnight can cause the battery to degrade over time. In general, it is best to charge your phone when the battery is low (below 20%) and unplug it once it reaches 100%. This will help prolong the overall lifespan of your phone's battery.

Also if you have an older phone, you might want to avoid charging overnight and rather to look into it replacing with a new one.
