Get started

Charge your device using the charger provided by BlackBerry in the box that your device came in. You can also charge your device using a USB cable connected to a computer, but charging might take longer.

CAUTION: Other chargers might not provide adequate power and might damage your device.

Plug the charger into a power outlet and connect the cable to your device using the USB port.

Tips: Charging your device

Your BlackBerry device uses a lithium-ion battery. To maximize your use of this type of battery, when possible, do the following:

Charge your device for an extended period of time rather than charging in small increments, for example, charging for less than 15 minutes.

Avoid using your device while it is charging, to help it charge faster.

Charge your device often, even when the battery charge isn't low.

Avoid leaving your device in extremely hot or cold places, such as on a vehicle dashboard.

Avoid leaving your device turned off with a low battery power level for an extended period of time.

Lock or unlock your device

Tip: A quick tap on the Power/Lock key will put your device to sleep. This should help you conserve battery power.

Lock your screen

By locking the screen, you can help prevent your BlackBerry device from sending accidental messages or pocket dialing. Locking your device doesn't disable alerts for incoming calls or messages.

Press the Power/Lock key on the top of your device.
