3 Don’t Let It Overheat
The Apple Watch, like most Apple products, won’t be permanently damaged if you leave it on the charger for a while. But the Watch still contains a lithium-ion battery, so it’s still important to exercise caution.
As a precaution, don’t leave it on the charger for extended periods of time. But, more importantly, you should be really mindful about not letting it overheat. That’s especially true if you live in a hot climate.
- Don’t charge your Apple Watch in direct sunlight or in other hot environments.
- Keep an eye on third-party Apple Watch chargers.
Your Apple Watch will warn you if it gets too hot, but it can lead to permanent battery damage over time (and shorten its battery life) if left unattended for too long.
