Kevin,
Here is an indication of my battery life. Full charge at 6:00 AM -> I then played Groove Music (non-streaming) music for approximately 40 minutes while driving to work -> While at work my reception sucks, especially in the building, so it looks for signal constantly; this was only for about 15 minutes -> I then drove about 70 minutes to school listening to Groove Music (non-streaming), it is noteworthy to say I was driving to a city where reception is 100% -> After class I drove 70 minutes back to work, again, listening to Groove Music (non-streaming) -> I was at work for the remainder of the day, about 5 hours and 30 minutes. After work I listened to Groove Music (non-streaming) again on the way home, about 40 minutes. During the day I used it very little except to look something up before class and and read a couple emails and texts. I was also on the phone tonight for about 2 minutes. So, overall usage was moderate and equaled approximately 13 hours and 30 minutes. As you can see from my screen shot below, I have 16 hours and 43 minutes left or 50% battery life. If you do the math you can see if it compares to what I am getting. As I stated in an earlier post, battery life can be different for any given user because of usage, connection, etc. So, take my numbers and compare. See if you get something close.
