I recently read the thread about not having to use any task killer and so I deleted the advance task killer. But since I deleted that my battery life was significantly worse. I realized then that weatherbug was running in the upper left corner. Although I have it set to update every 6 hours, it continues to update several times in a hour. I think this is why my battery life is so bad with it continually updating. So if anyone is running weatherbug an its running, check to see how often updates are apart. This may be a glitch in the software.
