Open Sleep Timer, choose a preset or Custom duration, and start the videos. The toolbar counts down; when time is up, playback pauses and the app requests a lower screen brightness.
Open the timer choices
Tap Sleep Timer. Choose 10, 20, 30, or 60 minutes, or use Custom. Don't enable is available here when you want to cancel an active timer.
Set a custom duration
Choose Custom, set 0 h and 01 min with the hour and minute wheels, then tap Confirm. Check the selected row before confirming.
Start playback and check the countdown
Return to the workspace, play the videos, and check the timer’s remaining time on the toolbar. Setting a timer does not replace the normal Play control.
Confirm that playback stops
When the countdown ends, check that both videos are paused. In this test the upper clip stops at 00:01.975 and the lower at 00:08.980. The countdown disappears.

Cancel from the same menu

Frequently asked questions
Does the timer start playback for me?
Use the ordinary Play controls to begin playback, then check both the video state and timer countdown.
Why is the screen darker afterward?
The timer also lowers screen brightness. Simulator screenshots show the paused video state; they do not prove a physical brightness change on an iPhone or iPad.
