Blackberry is sluggish

My Blackberry is sluggish lately when I'm typing on BBM. What could cause this and how do I fix it? Also, sometimes during a long conversation thread BBM stops letting me type more words unless I end the chat and start a new one. Does anyone know why this happens?:o

Issue 1-battery pull should solve it.
Issue 2- BBM does have a character limit in conversations

Try updating the OS. I had the same problem on my Tour but just changing to another OS took care of it.

Hold down your menu key and check to see how many apps are still open. There should only be about 5. Message, browser, home, phone and bbm cannot be completely shut down.

Battery pulls on a regular basis. Also use Quick pull application
Be sure to close out on a program when done
Delete text messages and emails when done with them
Clean browser cache regularly
Clear out the event log as well

These will help your BB perform much better
