Apple's new iPhone 4S handset has been dogged with criticism since its launch last month, with some owners complaining about the handset rapidly draining its battery life.
Some iPhone 4S users have reported that their phone battery loses up to 15% of its capacity every hour, even when not in heavy use.
Other issues have been reported with older iPhone models after the user had installed the latest iOS 5 operating system, which also caused various other problems when it rolled out last month.
