A few end-users who complained about battery life and are a part of Apple’s AppleSeed program, which allows Apple to invite select customers to test pre-release software, have begun receiving the update as well. Participants in the program are being warned prior to updating their device that they will be unable to downgrade to iOS 5.0, however, they will be able to upgrade to the final release when it is available.
9to5 Mac also obtained a picture of an internal memo to Apple Store employees, which instructs them, once they’ve ruled out any hardware failures, to inform customers who complain about battery life that “Apple has found a few bugs in iOS 5 affecting battery life and Apple will release a software update to address those in a few weeks.”
In addition to the battery life fixes, the iOS 5.0.1 update is expected to contain security improvements, add multitasking gestures to the original iPad, address bugs with documents in the cloud, and improve Siri’s voice recognition for Australian users.
