Charging the battery
To charge the battery, choose one of the options below:
- For the quickest charge, connect the device to a power outlet using the USB cable that came with the device and an Apple 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.
- 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 the device may not charge.
- Connect the device to an externally-powered USB hub.
- For the quickest charge, disconnect other USB devices.
If you charge the battery while syncing or using the device, it might take longer to charge.
Charging with a FireWire-based power source is not supported, except on original iPhone and iPod touch (1st generation). If the device is connected to a FireWire-based charger or accessory, this alert screen will appear:
Charging is not supported with this accessory.
Note: If this alert appears and nothing is connected to the dock connector, verify that the dock connector is free of debris.
Charging information for iPhone models sold in China
iPhone models sold in China can charge while turned off. When iPhone is off and connected to a charger or computer, a lightning-bolt icon appears on the display to indicate charging:
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 the battery charge is very low, the device may display one of the following images indicating that the battery needs to charge for up to ten minutes before you can use it. If the battery 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.
