iPhone and iPod touch: Charging the battery

To charge the battery, choose one of the options below:

• For the quickest charge, connect iPhone or iPod touch to a power outlet using the USB cable that came with the device and a USB power adapter.
• Connect the device directly to a USB port on your computer (not an external keyboard) using the USB cable that came with the device. Your computer must be turned on and not in sleep or standby mode; otherwise, the battery may drain instead of charge.
  • For the quickest charge while connected to a computer, remove all USB devices except the keyboard and mouse, or use an externally powered USB hub and connect the added USB devices including the iPhone or iPod touch.
  • If using a portable computer, make sure it is plugged in to power and that the display (or lid) is open. If the display is closed, the computer may go into standby, sleep, or hibernation mode and iPhone or iPod touch may not charge.

If you charge the battery while syncing or using iPhone or iPod touch, it might take longer to charge.

Note: Charging with a FireWire-based power source is not supported, except on original iPhone and iPod touch (1st generation). If you connect your device to a FireWire-based charger or accessory, you will see this alert screen:

Charging information for iPhone models sold in China

The battery indicator icon in the upper-right corner of the screen shows battery charging status and approximately how much charge is left in the battery. When plugged in to power, these icons will appear.

If iPhone or iPod touch is very low on power, it may display one of the following images indicating that the device needs to charge for up to ten minutes before you can use it. If the device is extremely low on power, the display may be blank for up to two minutes before one of the low-battery images appears.

Note: If you don't see the white charging or plug icons, your iPhone or iPod touch may be connected to a FireWire charging device. Connect the iPhone or iPod touch to a compatible USB charging device.

Battery life and number of charge cycles vary by use and settings. For more information, go to: www.apple.com/batteries/iphone.html or www.apple.com/batteries/ipods.html.

For information on how long the battery is expected to last between charges, see the iPhone or iPod touch technical specifications.

Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced.
