Yeaterday, Apple released the public version of the software fix for the battery issues experienced by many users who upgraded to iOS 5. The software update marks a new era in Apple updates as it can be done entirely over-the-air. This means you don’t need to connect your phone to iTunes to perform the update. Just go to the Settings app, tap ‘General’ and then Software Update. Doing it over the air consumes roughly between 39mb to 55 mb depending on your device while connecting to itunes will consume a whooping 790mb.
Apple claims iOS 5.0.1 fixes the battery drain, as well as some other bugs including the security vulnerability exposed by a hacker a few days ago.
It’s too soon to tell whether this update works but I’m upgrading my 4S right away. I’ll test it in the ‘real world’ and let you know if it’s a worthy upgrade.
As always, jailbreakers have been advised to stay away from the software update until further notice as it trashes your jailbreak.
