Application Management

Multitasking - Close any running BlackBerry® smartphone applications that are not being actively used. An easy way to see which apps or games are open is to press and hold the Menu key which causes the App Switcher to appear. Then switch to the application or game that is not being used and after pressing the Menu key, select the Close or Exit option to exit the application or game. Additionally, the CPU screen in the Application Management feature of the Options application will show the running applications that do not appear on the App Switcher screen. Applications that are not running will appear with Not Running under their name.

Closing Applications Correctly - Avoid using the End key to close applications as this simply minimizes the application and leaves it running in the background. Instead, press the Menu key, select the Close or Exit option to exit the application.

Closing Browser Tab – BlackBerry® Device Software 6.0 and higher provides a tabbed browsing experience. Ensure that tabs that are no longer in use are closed by pressing the Menu key, selecting Tabs, and clicking on the red X under the tabs that are no longer in use.

Configure Instant Messaging and Social Networking Application Settings – IM and Social applications may send and receive information on a periodic interval. These applications may have options or settings that will reduce the frequency at which data is transmitted. To further reduce the frequency at which data is transmitted, Logging out of IM and Social applications when they are not needed can further improve battery life.

Configure Podcast and Social Feed application settings – Podcast and Social Feed based applications may be configured to automatically download content on a periodic interval. These applications may have options or settings that will reduce the frequency at which data is transmitted.

Close Media applications – When pausing media playback, the application playing the media will still be running in the background. If media playback will not be in the near future, choose to press the Menu key and select the Close or Exit option to exit the application.

 

Wireless Connections

Disable Wireless Radios when not in use – BlackBerry smartphones feature multiple wireless radios Cellular, Wi-Fi®, Bluetooth®, GPS, and NFC connections. If one or more of these wireless connections is used, it is recommended to disable the corresponding radio to prevent it from using battery power. For example, if it is known that no connection will be made to any Bluetooth devices while at home or at a restaurant, a quick way to save some battery life would be to turn off the Bluetooth radio. To review and modify network connections on a BlackBerry smartphone, click the connections area along the top of the home screen, or select the Manage Connections icon from the home screen. Enabling and disabling network connections can be actioned by checking, or clearing the check boxes.

Low Cellular Coverage situations – When in low cellular coverage situations, the BlackBerry smartphone may increase power to the Cellular radio. In locations that have poor cell coverage such as basements, use the Wi-Fi functionality built into the BlackBerry smartphone to connect to available Wi-Fi network. If a Wi-Fi network is not available and cellular connection is not needed while in the low coverage environment, consider turning off the Mobile Network connection by click the connections area along the top of the home screen, or select the Manage Connections icon from the home screen and disable network connection by clearing the check box for Mobile Network.

No Coverage situations – When in an area without cellular coverage, the BlackBerry smartphone may continue to search for available mobile networks. In locations that have no mobile network coverage such as basements, use the Wi-Fi functionality built into the BlackBerry smartphone to connect to available Wi-Fi network. If a Wi-Fi network is not available and a cellular connection is not needed, consider turning off the Mobile Network connection by clicking the connections area along the top of the home screen, or selecting the Manage Connections icon from the home screen and disabling network connections by clearing the check box for Mobile Network.


Device Settings

Adjust Backlighting Settings – An easy way to see improved battery life is to customize the backlighting settings on a BlackBerry smartphone. As the BlackBerry display brightens, more power is consumed. Configuring the Backlight Brightness, Backlight Timeout, and Automatically Dim Backlight settings within the Options application to lower values will improve battery life.

Enable Auto On/Off Settings – The Auto On/Off feature of the BlackBerry smartphone, contained within the Options application, allows configuration of preset times at which the BlackBerry smartphone will turn on and turn off. Newer BlackBerry smartphones allow for separate Auto On/Off settings for weekdays and weekends.

Configure a Power Efficient Notification Profile – The speaker and vibration components of the BlackBerry consume energy when used. Consider configuring an energy efficient notification profile that minimizes use of these components by shortening the length of the notification as well as minimizing the number of times that the notification is produced. The vibration notification requires more power than other notification types, eliminating this notification type all together for an energy efficient notification profile, is a way to maximise battery performance. The LED light on the BlackBerry uses the least amount of energy, so for notification types where this form of notification is sufficient consider using it exclusively.


Maximizing Free Memory

Monitoring available memory
To see the approximate amount of occupied flash memory on the BlackBerry smartphone, complete the following steps.

For BlackBerry Device Software 5.0 and earlier

On the Home screen of the BlackBerry smartphone, open Options.
Select Status.
For BlackBerry Device Software 6.0

On the Home screen of the BlackBerry smartphone, tap All, then open Options.
Select Device.
Select Device and Status Information.
The File Free field shows the approximate amount of available flash memory available for data. To make sure that this value is as accurate as possible, restart the BlackBerry smartphone to initiate a full garbage collection. For instructions, see KB02141.

From the Status screen, press the Menu key, to the right of the green phone key, and select Database Sizes to view the number of objects and size of databases on the BlackBerry smartphone.


What is considered low flash memory?
The BlackBerry smartphone's Java® operating system has a complex and dynamic way of determining exactly how much available flash memory it should have before starting the Low Memory Manager application. To determine if it has low flash memory, the BlackBerry smartphone takes into account a number of factors, such as the BlackBerry smartphone hardware model, the operating system version, the number of installed applications, the frequency at which BlackBerry smartphone user data is added and removed, and so on. Generally speaking, the more the BlackBerry smartphone is used, the more memory the operating system sets aside for normal, efficient operation.

Note: When the BlackBerry smartphone has determined that is has low flash memory, it automatically starts the Low Memory Manager application, which reclaims memory.

The File Free field shows 0 - When the File Free field shows 0, it most likely means that the BlackBerry smartphone is full of data. The BlackBerry smartphone determines that it has low flash memory and performs more extensive garbage collections in order to make room for any new data. However, even when the BlackBerry smartphone is full of data, it is designed to operate properly. The Low Memory Manager application starts recovering flash memory when data is added that requires additional flash memory.
