iPhone 4S Battery Drain

Though iPhone 4S was a success setting market records & so many positive reviews, owners have been reporting a big problem with their new smartphone battery life.

"My iPhone 4 for the last few days has started to get very hot in use and the battery is gone very bad. Leaving the phone on standby can see the battery drain nearly 20% in an hour. This is gone to the stage where I have to turn it off at times just to save battery during the day..." From an official Apple forum.
