A few years ago, if you bought a new device, you may have been profusely warned not to leave them on charge for too long for a few that the battery may get damaged.
Even now there are some devices that are prone to overcharging and may get damaged if you leave them on charge for more than the required hours it’d need to charge.
Before lithium-ion batteries were in existence, the threat of overcharging was quite real. Now, however, Apple uses the lithium-ion battery in its gadgets. But the questions still remain.
Is it OK to charge AirPods overnight?
The short answer is yes, it’s safe. You can leave your AirPods overnight to charge. Your AirPods can’t overcharge and charging it overnight won’t damage their battery. This is because Apple uses lithium-ion batteries in this case.
They literally can’t overcharge, since the case is engineered to stop the charging process when the battery is fully charged. This means that even if your AirPods are still plugged in, the device will automatically stop the current flowing to their battery.
This makes it safe to charge your AirPods overnight.
