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’.

These are just a few ways to free up some wasted space on your device. Doing these things regularly can help to dramatically improve the speed and overall performance of your BlackBerry device.
