iOS 5.0.1 Download Now Available from Apple

Apple [AAPL] has released the final version of iOS 5.0.1 which promises to fix battery life. It is available for all iOS 5 compatible devices and ranges between 44Mb and 790Mb depending on if you install the smaller OTA delta update or get the full iOS via iTunes. The file size also varies between the iPad and iPhone by a few Mb.

As Apple now offers smaller delta updates to users, it appears that the strain on the Apple servers has been significantly lowered as updating seemed to run a lot smoother than it has in the past. If updating over the air, expect about 15 to 20 minutes to complete the process. For those updating with the full iOS 5.0.1 update, expect it to take less than an hour to download and install.

It’s a little too early to know if battery problems have been fixed, but there are some reports of users saying they are still seeing problems while others are not seeing issues any more. There’s also a bunch of users who never had battery issues who continue to report no problems.

Other additions include restoring multitasking gestures to the original iPad and bug fixes for documents in the cloud. Australian users of Siri on the iPhone 4S have also received better speech recognition with this update.

To get the update you can either plug your iPhone in to your computer and download the full 790Mb or so update or alternatively you can navigate to Settings > General > Software Update and grab the far smaller update from there. The smaller update can be downloaded over WiFi and I believe it requires 50% battery or more to install it. If the battery isn’t sufficiently charged it will ask you to plug the phone in to a power source at which point you’ll get the update right away.
