If you’ve used the YouTube app in recent versions of iOS 11, you might have noticed some significant battery drain happening and even your device overheating as a result. Luckily, this is the result of a bug and not necessarily everyday usage.
Uninstall YouTube temporarily. The video platform said it’s aware of the battery drain issue, and is working to fix it.
If you’d like to still view YouTube videos, you can do so with your favorite iOS web browser (which, if you’re a battery life aficionado, should probably be Safari).
