Best practice: Optimizing your device performance
Try to maintain at least 400 KB of application memory on your BlackBerry®device. To increase the amount of application memory, try
deleting items that you do not need from your device. Consider the following guidelines:
• Delete old email and MMS messages, especially messages with attachments.
• Delete contacts that are already in your organization's address book.
• Delete applications and languages that you do not use.
• If you recently upgraded the BlackBerry® Device Software over the wireless network, delete the previous version of the BlackBerry
Device Software.
• Clear the browser cache.
To use less memory, try changing options for email messages, calendar entries, and media files. Consider the following guidelines:
• Reduce the amount of time that your device stores email messages and calendar entries.
• Stop forwarding email messages to your device when your device is connected to your computer.
• Receive only the first section of long email messages.
• Reduce the maximum amount of device memory available for all media files.
• If you changed the picture quality for pictures that you take, change the picture quality setting to Normal.
• Reduce the picture quality in the browser.
