Another thing for others to consider.. The phone is a new toy, at least to me it is. This means I'm opening and fiddling with it far more than I ever would have with my iPhone 4 on any given day.
After 1.5 hours talk, 85 texts, 3 hours of music, and a hour or so of having IM+ on I am now in the yellow. I took it off the charger at 8:00am this morning and its 4:45pm right now.
It says "screen" is 71% of the usage, which tells me that I have been opening and playing with the phone quite a bit too. I at times caught myself just turning it on and flipping through menus. Its new, like any new gadget I tend to play with it more than when I've had it for 6+ months.
While I think the battery time could be better, its not horrible. Honestly if I have to plug it in to my work laptop for a little afternoon juice I really don't care. It's just sitting on my desk, why not sit there and charge too? So far I haven't had to do that yet.
I do have a car charger that I got for free in a accessory kit when I bought from Costco, but I have yet to use it.
