3. Charging Times

• Charge times will depend on the BlackBerry® smartphone being charged and what power source is charging it. BlackBerry smartphones come with lithium-ion batteries, which should be kept topped up regularly. Many factors affect the length of time the battery can operate before recharging, such as the amount it is used, the applications that are running, the brightness of the screen and even the volume of the ringer.
• When the BlackBerry smartphone is plugged into a computer with the correct USB drivers installed, it will charge approximately five times faster than when plugged into a computer without the correct drivers installed.
• A travel charger charges a BlackBerry smartphone at a rate equivalent to or higher than a computer with the appropriate USB drivers installed. Using a travel charger that is plugged into a wall is the fastest way to charge a BlackBerry smartphone.
• It is important to charge each BlackBerry battery with the correct charger. Each travel charger for a BlackBerry smartphone is designed to charge a specific type of BlackBerry battery. For example, only charge C-Series batteries with the BlackBerry C-Series Battery Charger.
• The front label on the battery displays a letter (such as "C-") and the battery model number. This will help make sure you are using the correct battery type with the correct travel charger for a BlackBerry smartphone.
