If you use your iPhone as a PMP, and need to reset it without losing the songs in your iTunes library (non-destructive), then a soft reset is a good place to start. There can be times when simply listening to a song can result in a frozen iPhone. Rather than restoring the iPhone which deletes all your iTunes Store purchases, and other information (factory defaults), simply rebooting your Apple device can be all that's needed. Follow these steps to see how.
Time Required: 1 Minute Max.

Before you try anything, it's worth making sure that your iPhone has enough power in its batteries. It is a common situation that can make it look as though your iPhone is dead and therefore not resettable. In actual fact it may only need a little extra juice in its batteries in order to perform a reset cycle. If your iPhone won't turn on:
- Plug your iPhone directly into a computer USB port (not hub) or use the power adapter that came with it.
- If the screen is blank then this usually indicates that your iPhone's battery is very low on charge -- wait up to 5 minutes to see if you get a battery icon displayed. For more information on battery life, be sure to read our Tips on Preserving Your Battery.
