I have an iPhone 6s 128 GB on iOS 10.3.3. I've noticed that for the past couple weeks or so, the official YouTube app drains the battery really quickly while watching a video. The phone also warms/heats up while watching a video when previously I never noticed an increase in temperature while watching videos. I haven't changed anything and the YouTube app is always up-to-date. I do remember one thing though. Just before this started happening, the YouTube app crashed when switching from the subscriptions list tab to the home tab. This is the first crash I've gotten with the YouTube app. After that crash, it seems it drains the battery real quick and heats up the phone when watching videos. I've tried deleting the app and reinstalling it and it made no difference. Restarting the phone also made no difference. Any ideas?
Just to give you an idea, I was just watching an 11 minute video and the battery went from 67% to 61% by the end of the video.
Even though the phone has a 750p screen, I watch videos with the quality to the highest setting (1080p/1440p). Even with these settings, the phone would never heat up or drain the battery really quickly previously.
Also, when the phone heats up, it heats up right around the rear camera lens.
