Here my usage, standby and battery % after 5.0.1 install and charge to 100%. Good, bad? I don't know. Still think my 4 was better.
2 hrs. use with 12 hrs. standby at 68% sounds fine. If you were on 3G all that time it might even be great.
Unless you plan to recharge every other day (40-48 hrs. standby), I think most people should fall into a routine of charging the phone every night while they sleep (16-20 hrs. standby). With that in mind, you have nothing to worry about at 68% after 12 hrs. standby.
Or am I missing something? Aside from some Blackberry models with small screens and users who spend most of their time messaging and emailing (lousy browser & few useful apps), what modern smartphone can go 2 full days of use without a recharge?
Just plug the phone in every night and use the heck out of it during the day. If you can't get through a normal day without excessive battery management (no constant turning this and that on & off), call Apple to complain and ask for help.
Forums always amplify the perception of a problem. It's the squeaky wheel syndrome, which is fine. Even if this issue affects less than 10% of iPhone users, it still deserves attention and a solution. iOS 5.0.1 seems to solve the issue for some with the problem, but not all. So Apple will try again with 5.0.2.
I know I'm going to risk flames for this next bit, but these iPhone battery issues pale in comparison to what Android phone users have been experiencing. First, those problems affect the majority of users rather than a minority. Second, there is little hope of a solution from either the carrier, phone manufacturer or Android. Even if Google released an OS update to help solve the issue, when will HTC, Samsung, Moto, etc. pass on the update to their devices?
So the solution for many Android users is to carry a charger with them, buy & keep a spare battery charged, install & manage a power management app.
