Extend Battery Life - Blackberry®
Battery life is measured by standby time and talk time.
Standby time is the amount of time the device stays powered on with no voice, data, or other usage.
Talk time is based on voice usage.
Using data such as web browing, apps, or streaming reduces overall talk time.
In order to improve battery life, you can:
when device is not being used.
Use only the Tone Notification.
Turn off the backlight if not used.
