Apple issued a brief statement Friday following reports that some users of the iPhone 4S are continuing to see battery life problems despite a fix released in yesterday's iOS update.
"The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices. We continue to investigate a few remaining issues," Apple said in a statement to All Things Digital.
Apple rolled out iOS 5.0.1 yesterday in large part to address the battery-drain situation, but some users say their batteries are still losing charge at a fast rate. You can read more about that here.
