Charging the <strong>iPhone</strong><br />

The <strong>iPhone</strong> has a built-in, rechargeable battery that fills up a substantial chunk<br />

of the <strong>iPhone</strong>’s interior. How long one charge can drive your <strong>iPhone</strong> depends<br />

on what you’re doing—music playback saps the battery least, Internet (especially<br />

3G Internet) and video sap it the most. But one thing is for sure: Sooner<br />

or later, you’ll have to recharge the <strong>iPhone</strong>. For most people, that’s every other<br />

day or (if you use 3G) every night.<br />

You recharge the <strong>iPhone</strong> by connecting the white USB cable (or the white<br />

syncing cradle) that came with it. You can plug the far end into either of two<br />

places to supply power:<br />

• Your <strong>com</strong>puter’s USB jack. Just make sure that the Mac or PC won’t go<br />

to sleep while the <strong>iPhone</strong> is plugged into it. Not only will the battery not<br />

charge, but it may actually lose charge if the <strong>com</strong>puter isn’t turned on.<br />

• The AC adapter. The little white two-prong cube that came with the<br />

<strong>iPhone</strong> snaps onto the end of the cradle’s USB cable.<br />

Unless the charge is really low, you can use the <strong>iPhone</strong> while it’s charging. If<br />

the <strong>iPhone</strong> is unlocked, the battery icon in the upper-right corner displays<br />
