We have ran several guides for helping users make their BlackBerry devices run faster. We continue to run these guides along regular content because users continually ask these questions and we cover a little more in each one. If you want to make your BlackBerry running OS 5 or OS 6 faster, click through and read these tips.

Here are a few tips and tricks that will help improve your BlackBerry’s speed and performance (demonstrated below on a BlackBerry Curve 9300 running OS 5.0.0.997 and a BlackBerry Bold 9700 running OS 6.0.0.534).

Check Your Device’s Available Space

It’s always a good idea to periodically check how much memory is left on your device. This is a fairly simple procedure. Here’s how:

For OS 6 devices

Go to ‘Options’ > Scroll down to and select ‘Device’ > Scroll down to and select ‘Device and Status Information’ > Scroll down to ‘Device Information’ > your ‘Free Memory’ will be shown in bytes.

For OS 5 devices

Go to Options > Status > File Free tells you how much free space your device has in bytes.

Close Applications Running in Background

Often times, a device will lag because applications that weren’t closed down properly are still running in the background. Checking this regularly is a also a great way to maintain speed and performance. Here’s how:

For OS 6 devices

From your home screen, press the BlackBerry button and select ‘Switch Application.’ You can also press and hold the BlackBerry button to get the same effect. As you can see below, this will display all of your applications that are currently running in the background. Go into each application and close them manually to ensure they are exited properly.

For OS 5 devices

From your home screen, press the BlackBerry button (the button in between the answer key and the trackpad) twice to display an options menu. From there, scroll down to ‘Switch Application’. This will display all applications that are currently running on your phone. Go to each application and exit from them properly.

(Pro-tip: when you’re doing with an application, be sure to exit it properly each time rather than just hitting the red BlackBerry hang-up key. This way, you’ll get into a habit of exiting applications and not having to go back and do it manually all the time.)

Clear Your Event Log. Often.

Your BlackBerry stores everything. When you opened an app, when you closed an app, mobile websites you’ve visited, what you’ve downloaded, what you’ve deleted, etc. That’s a lot of information to be storing. Here’s a quick way to clear out all of that wasted space:

Hold down the ‘alt’ key and type ‘LGLG’ (lower case, without quotes). This will take you directly to your device’s Event Log. From there, press the BlackBerry button and select ‘Clear Log.’ This operation is the same for both OS 5 and 6.

Enable Automatic Memory Cleaning

For OS 6 devices

Go to ‘Options’ > Scroll to and select ‘Security’ > ‘Advanced Security Settings’ > Scroll to ‘Memory Cleaning’ > Select the box beside ‘Enable’ to enable regular memory cleaning.

For OS 5 devices

Go to ‘Options’ > Scroll to and select ‘Security Options’ > Scroll to and select ‘Advanced Security Options’ > Select ‘Memory Cleaning’ > You’ll see a drop-down menu, select ‘Enable’.

Clear Your Cache

Much like your desktop browser, you BlackBerry’s browser also stores content cache which can take up a lot of unnecessary space. It’s a good idea to do this often, depending on how much you use your BlackBerry for internet browsing.

For OS 6 devices

Open your browser > Press the BlackBerry button to reveal a menu > Select ‘Options’ > Scroll down to the bottom where it says ‘Clear Browsing Data’ (shown below) make sure the box beside ‘Cache’ is checked > Select ‘Clear Now’.

For OS 5 devices

Open your browser > Press the BlackBerry button to reveal a menu > Select ‘Options’ > Select ‘Cache Operations’ > Under ‘Content Cache’ you will see a ‘Clear’ button. Select ‘Clear’.

    Just a FYI, but enabling the memory cleaner often causes more problems than good. This feature was built in for security reasons to ensure that sensitive information does not remain on the phone. But it also adds to the open processes on the device, which can actually slow your BlackBerry down over time, or can cause a whole other set of problems. This is not recommended to speed up your device and should only be used for security reasons.

    Enabling Memory Cleaner on your BlackBerry will NOT speed it up nor enhance your experience. In fact, it will slow it down, cause severe lag and drain your battery. The only users who need Memory Cleaner enabled are employees of seekrit gub’ment spy agaences and dealers in drugs and p0rnography.

    I already know this info far before.
    My only problem is my storm has only small memory left after upgraded to OS 5.
    What RIM shoud do are :
    1. Smaller OS
    2. Ability to move application to SD card.
