Extend Battery Life - Samsung Galaxy™ Stratosphere™ II

Battery life is measured by standby time and talk time.

Talk time is based on voice usage.
Using data such as web browsing, apps, or streaming reduces overall talk time.

Stop running apps that are not being used.
Disable apps that are consuming too much battery or RAM and not being used.
Turn off Bluetooth when not in use.
Adjust display settings to lowest setting or use Automatic brightness.
Turn off GPS when not in use.
