If you like to listen to the iPhone as you go to sleep, there is a sleep timer function that can automatically stop playing music or video after a set amount of time. The function is sort of hidden within the iPhone’s Clock app.
How to Set the iPhone’s Sleep Timer.
1. Open the Clock app.
2. Tap the Timer tab in the bottom right:

3. Set a time you want the iPhone to countdown:

4. Tap When Timer Ends button:

5. Tap the Sleep iPod button that is above the list of ringtones. If it’s not visible, drag your finger downward on the screen to make it appear:

6. Tap Set:

7. Tap Start:

When the timer reaches zero, it will close the iPod app and also any other open application, lock the iPhone, and place it in sleep mode.

I tried this listening to Pandora, and it would never turn off. Do I have to listen to non-internet music?

Brilliant. Appreciate the assistance – now just need to expand it to include a turn-off feature for Contacts who don’t know when to hang up.

Is there a way to do that for the apps like Pandora? I like going to sleep listening to a station on Pandora.
