Download iOS 5.0.1 with battery fix now

Apple has released the first official update to iOS 5, which fixes the reported battery drain problems.
In addition to fixing bugs related to battery life, the update to iOS 5.0.1 also adds multitasking gestures for the first iPad, resolves some bugs with Documents in the Cloud, and improves Siri’s voice recognition for people with Australian accents.
Remember that with iOS 5 you can now install software updates over the air. So there is no longer any need to wait until you get home, grab a cable, and connect to iTunes on a PC in order to apply the update. Simply open your Settings app, choose General, and then Software Update to initiate the process. The delta update file is less than 40MB, and should only take a couple of minutes to install over WiFi.
Apple was probably wise to get this update out early, as the battery drain issue was starting to get a lot of media attention. First thought to be attributed to the iPhone 4S, Apple support forums were flooded with pages of complaints about unusually short uptime on the latest handset. PC Mag’s testing then suggested that the issue was more likely connected to iOS 5 than specifically to the 4S. While most users didnot appear to have terrible battery drain, some did and few were reporting stellar uptime.
Developers who had installed the beta version of 5.0.1 reported dramatic improvements in battery life, so this could be just what the doctor ordered to fan those flames. We will do some testing and report back, but if you have been having drain problems on any iOS device, we’d recommend installing this update right away.
