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 media files from the device memory.
  • Delete applications and languages that you do not use.
  • If you recently updated 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.
  • Store media files on a media card.
  • Reduce the maximum amount of device memory available for all media files.
  • Reduce the minimum amount of device memory available for pictures.
  • 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.
