A calibration cycle, if needed, won't do much for battery life.I've pretty much got all location services off, or only active "while using app" on stuff that requires it (1 or 2), no push notifications either. My screen is 3/4 up to max, but it always has been. I hate a dark screen. Also, no app auto. updates.
I'm going to do the big "drain-then-charge" routine tomorrow and see if it helps at all...although I still think that went the way of the covered wagon.
We'll see. I do hope it gets better. I've never had to put an iPhone on a charger at my desk before I left work for the day since I had my 3s. :straight-face:
A software update shouldn't change battery life by much, so there's probably somethings wrong in your current iOS installation or a misbehaving app.
Your only chance is to restore as new an install apps again from the App Store
