why Application Storage cause Blackberry lag?

As stated in topic.  I'd like to know why app storage cause blackberry lag.  I still have some space left, I thought that the blackberry will start lag if there's no space left.
How does it work actually?

Re: why Application Storage cause Blackberry lag?

Hi and Welcome to the Community!


The technical discussion is far beyond me (Java stuff), but there are others who can hold that discussion if you really desire.


But, typically, the BB will begin to lag when AppMemory becomes too low...but what "too low" is varies widely as well, so without that full technical discussion, it's impossible to tell you specifically how your device should act. In general, if you have 50MB or more of free AppMemory, then there shouldn't be problems...lower than that and problems could begin.


Here are some guidelines to use:

  • KB02843What is the Low Memory Manager feature on the BlackBerry smartphone
  • KB14320How to maximize free space and battery power on the BlackBerry smartphone
  • KB14213Call logs, SMS text messages, and email messages are deleted from the BlackBerry smartphone

It is always important to properly close applications when you are done with them. Using the Back or the Red key will not do this -- those leave it to the app to decide what to do...and some will leave themselves resident in memory, consuming resources on your BB, slowing the overall performance. Rather, to close an app, press blackberry_logo.jpg and select "Close" or "Exit"...that will force the application to be closed, freeing up for your new use the resources it was consuming. Some apps will always remain running (typically -- BBMessenger, Browser, Homescreen, Phone, and Messages)...but, you should still close them properly - especially the Browser...if it is left on an active web page, it will not only consume extra resources but battery power as well.

Further, anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure. Some have taken to doing this on a regular basis as a preventive measure...some as frequently as once per day. Others have obtained the QuickPull app to automate a simulated Batt-Pull.

Good luck!
