How to maximize battery power
Battery power can be maximized by following these simple suggestions.
Use BlackBerry smartphone shortcuts to access common system features quickly. For instructions, see the Getting Started Guide for your BlackBerry smartphone. Using shortcuts allows you to do the same things on your BlackBerry smartphone more quickly and efficiently, while saving battery power.
Some common shortcuts include the following:
To delete a highlighted item, press the Delete key.
To select or clear a check box, press the Space key.
To view available values in a field, press the Alt key.
To switch applications:
Hold the Alt key and press the Escape key.
Continue to hold the Alt key and highlight an application.
Release the Alt key.
Set the Auto On/Off option to turn off the BlackBerry smartphone at a time of day when you are not using it (such as at night), and turn on again at a time of day that you are ready to use it (such as in the morning just before you wake up). Battery power is saved by turning the power off at times when the BlackBerry smartphone is not being used.
To set the Auto On/Off option on the BlackBerry smartphone, complete the following steps:
On the Home screen of the BlackBerry smartphone, open Options.
Select Auto On/Off. For BlackBerry Device Software 6.0, select Device then Auto On/Off.
Specify the on and off times.
Tip: Set the BlackBerry smartphone to turn on just before you need to use it, (such as a few minutes before you wake up in the morning) so that the BlackBerry smartphone has a chance to receive the email messages sent to you during the time that the BlackBerry smartphone was turned off. This way, the email messages have already been received when you are ready to read them.
When a particular wireless connection is not needed, use the Manage Connections application on the BlackBerry smartphone to turn off the connection. For example, if you do not need to use Bluetooth® technology, you can use Manage Connections to turn the Bluetooth connection off.
To turn the Bluetooth connection off on the BlackBerry smartphone, complete the following steps:
On the Home screen of the BlackBerry smartphone, open Manage Connections. For BlackBerry Device Software 6.0, tap the Network Indicator area of the screen in top right corner.
Click Bluetooth.
Note: Using Manage Connections, turn the mobile wireless transceiver off when you know you are out of range of the mobile network. Turning the mobile wireless transceiver off prevents the BlackBerry smartphone from continually attempting to locate the mobile network, which uses a lot of battery power.
Adjust the backlight settings to conserve power
For BlackBerry Device Software 5.0 and earlier
On the Home screen of the BlackBerry smartphone, open Options.
Select Screen/Keyboard.
Change the Backlight Brightness to a lower number.
For BlackBerry Device Software 6.0
On the Home screen of the BlackBerry smartphone, tap All and open Options.
Select Display then Screen Display.
Change the Blacklight Brightness to a lower number.
