It's true, I do love my iPhone! My family would say I'm obsessed with it! But what I'm observing lately is that the battery level seems to be dropping faster than before even when I'm not using it.
For example, this morning I used my fully charge iphone for 2 hours, mainly listening to podcasts, reading ebook, and reading a couple of emails. Battery dropped to 70%. Not stellar, but I could accept that. But then, over the next 5.5 hours I used it for 20 minutes tops, to look up some numbers, and battery life dropped to 45%! That's crazy! I do not have push email or bluetooth turned on in order to save battery life. I do have on 3G, WiFi, & Push, and I keep brightness set at about 40-45%. I also have a decent # of 3rd party apps, but since they're not allowed to run in the background, they shouldn't be draining the battery, right?
