My battery dies half way through the day without even using it, is there something running on the phone draining the battery?
BBM ( blackberry messenger) could be a drain, especially with that many contacts pinging you all day long. Is your brightness on high? That is another big power drag. What apps are you running?
What themes have you installed? You can try reinstalling the OS. Check what applications are running on your device in the background, press the Menu key then choose Switch Applications. You will see the icons of each application there.
There are commonly four or five applications that will always be running (Messages, Call Logs/Phone, BlackBerry Messenger, Home screen, and the Browser; there are other third party applications such as Bee Jive, and BlackBerry Alerts which will also run in the background which you cannot close if you want them to operate). Make certain that the browser is NOT on an active webpage (open the browser and choose Menu > Close). Close any other applications that do not need to be running (the camera or a game you were playing or Google Maps).Also make certain BlackBerry Maps is not running in the background.
Do a simple reboot: With the BlackBerry device powered ON, remove the battery a few seconds and then reinsert the battery to reboot.
Now, watch your battery use the next few days again and see how it goes. Make sure you close or exit ALL applications properly: If you just hit the red "end call" key to go back to the home screen the application actually stays open and running in the background. If you do this repeatedly you will have lots of apps open and consequently your memory will get used up. Lack of memory is the biggest reason your BlackBerry slows to a crawl or locks up. If you get into the habit of actually using the menu key to close the applications this will at least slow down this battery drain and memory-clogging process.
