Will Apple fix the iOS 5.1 battery drain issue?

People keep giving battery saving solutions to the iOS 5.1 battery drain problem but that is not the issue. With iOS 5.0 battery life was terriable. Apple quickly fixed it with 5.01. Now with 5.1 battery life is back to terrible. I could go at least two days without a charge. After the update (and all my patterns and behaviors being the same), I don't even get a full day! Apple needs to fix this! Or allow us to go back to iOS 5.01. Will Apple fix this and if so how soon can we expect a solution?
