Apple has admitted that several bugs in the recently launched iOS 5 operating system are to blame for the battery power problems experienced by users of the iPhone 4S and other Apple devices.
Thousands of iPhone 4S buyers reported problems with the smartphone on the Apple web site, complaining that the battery drains extremely quickly even with light use.
Some said that the 4S is unable to last a full day on a single charge when features such as push notifications and Wi-Fi are turned on for any significant period of time.
Apple finally responded to the concerns on Thursday in a brief statement.
"A small number of customers have reported lower than expected battery life on iOS 5 devices," the firm said.
"We have found a few bugs that are affecting battery life and we will release a software update to address those in a few weeks."
V3's tests of the iPhone 4S confirmed the battery issues. The phone needs charging more frequently than older models, and using the notifications feature to the maximum 15 minutes wipes the battery within half a day.
