Since upgrading to iOS 11, a lot of users started to complain about crazy battery drain because of the official Youtube App. The app was consuming a lot of battery even while it was running in the background. Users started to complain on the social networking sites and took it to platforms like Reddit before it was noticed by Google.
The tech giant has now come out in open and has talked about the issue, with a confirmation that the same will be resolved soon as possible.
Hi there! Appreciate the report, this is something we’re actively working on. Thanks for your patience.

Though the problem wasn’t universal with everyone, a few users complained of getting their phone heated up. Also, on reddit, a few of the users pointed out that the issue arrived after they updated to iOS 11.1.x and later. Youtube seems to be looking into the matter and the same should be resolved soon.
