The surest way to slow down your BlackBerry smartphone is to allow too many applications to be open and running simultaneously. It kind of sneaks up on you. The solution is to close out non-essential applications. Newer BlackBerry smartphones allow you to press and hold the BlackBerry menu button, which brings up a list of open applications. You can then choose which apps to close. Some applications should remain open at all times, such as “phone”, “browser”, “clock”. However, many non-native apps like Viigo and Ubertwitter can slow down your phone.


  1. 1

    Select an app that is open.

  2. 2

    Press the BlackBerry menu button and scroll to the bottom and select “Close”.

  3. 3

    Repeat Step 2 until you have fully exited the application.

Tips & Warnings

  • Another way to improve your phones performance is to purchase an application that maximizes your phone’s performance, clears your cache and frees up space. “MemoryBooster” is one app that reclaims wasted space and is available at the BlackBerry App World.
