If I take the phone off the charger in the morning, I'll get about 8-10 hours, with my typical usage habits. I've had as few as six hours, with heavy use. Now that LTE is trickling into my area (we're up to five towers!), I've switched the phone to 3G/4G mode. That will probably shorten my battery life a little more.
I'm now in the habit of keeping a charger in the car, and at my desk at work. That's the only way that I can ensure the battery will last until I get home.
Aside from that, I like the phone.
