Well here is something you did not expect. Apple failed to keep its promise regarding the battery life problem. According to its change log in iOS 5.0.1, it was supposed to solve the much talked about battery issue but it has failed to do it.
Apple forums are again full of people ranting about that the recent update has had no effect on the battery life. Here are what some people are saying about this update on Apple forums.
Updated about 1.5 hours ago, battery has drained 20% since then with no usage! This is awful!
New update is no help at all.
I opened the safari and lost 2 % just by opening the safari browser…This really *****
Some people are so fed up of this issue that they just want to get back to older firmware which did not show any problem with the battery life
Is there any way to revert to the previous version. I’m bleeding like a stuck pig.
The battery problem is not only confined to iPhone 4S on iOS 5 but many other users who own an iPhone 4, iPad 1/2, iPod touch are facing some of these problems too.

According to some other users, they are not able to download iOS 5.0.1 via OTA (Over The Air).
We expect iOS 5.0.2 to come soon to fix both of these issues.
