Recently replaced my storm due to a hardware issue. Have not re-installed weatherbug since, and doubt I will. My battery life has improved greatly without having weatherbug installed. Went from lasting 24 hours, I now get 2 days + out of the battery. I would suspect that weatherbug is constantly checking and updating. On previous blackberrys I ran weather bug, but it had options so you could set how often it would update. Anywhere from hours to every 30 minutes. Would like to see that option in this version, maybe it will help battery life.
