Hi, I am using an iPhone 4S since last 8 months. It was working great with iOS 5.0. I recently found a news where i read that Apple has rolled an update for iOS to 5.1.1. So as my firmware was too old, i updated it to the latest. But since than i realize that my iPhone's battery is draining quickly compared to earlier.
As this is my first ever iPhone and Apple product, i dont have any idea what to do. Could you guys please help ? All helps will be appreciated.
