Abnormal Battery drop - mobile network signal??Support

    I've been trying to figure out what's going on with my battery life overnight. Battery life is good through the day, drops much faster overnight. I've factory reset probably half a dozen times, slowly added apps back, etc. At this point the only thing I can point to is the mobile network signal. Here's my story from yesterday:

    Fresh charge to 100% at 9:00 am at work. Very minimal use (to rule out the screen use), even had my google account sync off. At 4:00 pm (7 hours) the battery dropped to 97%, or .4%/hour (excellent). My mobile network signal was constant, according to my battery graph:

    I turned my Google accounts on to sync automatically at 4:00, and over the next 6 hours my battery dropped to 89% (1.3%/hour). I could still live with this usage, but I noticed my mobile network went black around 8:30 pm, and see the graph dip a little with it:

    So I let the phone go overnight and checked it at 6:00 this morning (8 hours) - battery dropped 22% (2.8%/hour - not acceptable). No other settings were changed, but notice the mobile network being black:

    But did I actually lose the mobile connection? GSam doesn't show that I did:

    And looking at my wife and daughter's S2 (my N2 sat right next to my wife's S2 overnight), their mobile signal is full/good all through the night.

    So what the heck does all of this mean? I've watched this happen over different nights - occasionally it doesn't through. Do I have a lemon with a bad radio, or is it the combination of the N2 and AT&T in my location that I'm just going to have to live with? I don't understand this band talk enough - my sim is coded to LTE, but I'm pretty sure we're not in an LTE area. Looking at the graphs, I don't know that that matters though - it looks like it's something with the phone signal.

    I have about a week left in my return window (bought it outright thru Amazon). Should I just exchange it? Any other troubleshooting ideas?

    Thanks
