Reportedly, the iOS YouTube app is consuming excessive battery power, even when it's closed and running in the background.
Luckily, YouTube has confirmed that they are aware of the excessive battery drain and are "actively" working to fix the issue.
Based on the timing of some of the tweets and several posts on the MacRumors forum, the issue has been around for some users since at least the release of iOS 11.1.
"While using the official YouTube app even when I'm playing 720p videos the phone overheats as if I'm playing a very resource hungry game and battery drains very fast", wrote Redditor tahertalha, noting that they first noticed the issue after updating to iOS 11.1. Whatever the cause, the bug appears to be having a significant impact on battery life. If you're anxious about the app using up your battery, you might want to uninstall the app and simply use the YouTube mobile website in safari or chrome instead.
The newest operating system released by Apple fixes a rather unusual autocorrect bug and some argue that apart from that it might bring more disadvantages when installing. Depending on whose complaint you listen to, the battery goes down 20% in fifteen minutes to half an hour of watching video, which, by all counts, sounds pretty awful. That means that you could deplete your entire 100% fully charged battery with less than an hour of video watching on the YouTube App. Some other problems reported were camera bugs, notification breaks and the two main foxes not working.
