Thank you for sharing your experience. We've seen a few similar reports regarding increased battery usage with YouTube during the current Beta. While it's expected that some apps may behave differently during Beta software testing, we recommend checking for the latest version of YouTube via the Play Store, and clearing the app cache to see if it improves performance.
If the issue continues, please consider submitting an error report through the Samsung Members app with system logs attached. This will help our team investigate further.
