How to set a sleep timer for web video on iPhone (YouTube / Bilibili)
Set a sleep timer for YouTube, Bilibili, and other web video on iPhone—countdown, fade-out, and background play steps.
Why a web sleep timer?
With Safari, bedtime web video often stops on lock—or runs all night and drains the battery. XBrowser combines background play with a Sleep Timer in one flow.
Steps
- Open YouTube, Bilibili, or another web media page in XBrowser.
- Start playback, open Sleep Timer, and pick a duration (for example 30 minutes).
- Lock the phone. Playback can continue; near the end it fades out and stops.
Tips
- White-noise and podcast sites work the same way.
- If a site blocks background media, results may vary—prefer pages that expose a media session.
