Yesterday was my first full day with it. I'm not that heavy with usage of the phone throughout the day since I'm in front of a computer all day at work, but I do have the phone connected to the corporate wifi when I'm here at the office and it's generally always on wifi when available.
The phone came off the charger at 6 am yesterday and by 3 pm it was down to about 48%. I guess that's about normal-ish. I never have Bluetooth on if I'm not in the car and I've apparently had to turn Location on now...it seems like that's "all or nothing" now...no more of that "halfway" option, which was how I had it set before. Rarely would I need to use Location/GPS, and if I was using the GPS in the car, it was on longer trips and I'd have the phone plugged into a car charger.
Lately during the day at work I have been plugging the phone up to a charger as a "just because" measure, at least for a little bit.
My typical day normally consist of maybe a few texts, some very light internet usage (again, I'm at a PC all day), and the heaviest usage it gets is when my girlfriend calls me on her hour-long ride home in the evening. Then after that I might check in on the 'net before going to bed, and then back on the charger it goes overnight.
Guess I'll see how it goes.
