I have no idea, I don't know what it considers "Awake," because it shouldn't be awake when I put it to sleep...? Right? My nexus was just sitting on my nightstand most of the time, I dont know why it was awake or not awake at times.One question though. I see your phone was not awake for most of the time. Why is that? Mine is awake 100% of the time.
I looked at a couple different apps, and I settled with Llama, works great for me now. I just wish I didn't have to resort to that.I think you nailed it - it was trying to find a 4G or 3G tower, and was likely switching between the two. The Juice Defender app will automatically disable your data upon connection to WiFi - that should solve your issue. Other than that, there is nothing wrong with plugging it in everynight, and I definitely would.
