    This question/post comes up so many times (month after after, year after year), any never does anyone ever describe in comparison how their battery is worst.

    Under iOS 4.x, my battery performance used to last me 6.5 to 7hrs of total usage before my phone would shut down, now I am getting over 8hrs under the same conditions and same app usage on my same iPhone 4.

    But when I installed iOS 5, I did set up my device as new and I did not restore from a back-up.

    How about this: performing the same actions on two iPhone 4 phones (one with iOS 5 and one with iOS 4) that are configured the same way and have the same applications running shows that the rate at which the battery gets used up on the phone with iOS 5 is roughly 1.5 - 2 times faster than that on the phone with iOS 4. And this isn't when just doing a quick test, but it's more or less continuously like that, based on a number of different comparisons over the past few days (if not a bit more).

    It's actually noticeable when after a matter a few minutes (generally between 3 and 5) of using the iPhone 4 with iOS 5--simply doing basic things like checking for app updates, checking/reading email, browsing a few web sites, perhaps reading/sending a few text messages--goes down by 1%. It's actually fairly noticeable, whereas on the iPhone 4 with iOS 4 you don't really see the battery going down as often--you don't even really notice it under normal use, and it's not all that often even when you watch for it.

    In terms of standby time, it seems like not much might have changed, at least not in a noticeable way (so far).

    Almost always it's an app that's running in the background or one that's gone native. Turn your phone on and off to clear all apps and memory. As an interim step you can close all the apps in your recently used app list and see if that resolves the issue.

    No harm in taking your phone to Apple, but there's a 99% chance that it's an app on your phone.
