Apple issued a software update to its latest mobile operating system on Thursday in a move to fix widespread problems with the battery life of the iPhone 4S.

The software update, iOS 5.0.1 also adds multi-tasking gestures to early versions of the iPad and closes a security loophole that could have duped users into loading malware onto their iPhones and iPads through Apple’s App Store.

Complaints about the disappointing battery life began popping up immediately after the release of the iPhone 4S last month, which Apple acknowledged in a statement last week.

“A small number of customers have reported lower than expected battery life on iOS 5 devices,” Apple wrote. “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.” The software update was the first one issued by Apple that was pushed to users over the cellular networks, rather than requiring them to sync up their devices with their laptops.
