Default Samsung Galaxy Nexus - Battery Life Question

Yes, well aware of the GNex's battery woes. Have used the phone for two years on VZW, recently bought a Nexus 5 so I'm just now getting started with unlocking, rooting, flashing ROM's, customizing the interface.

So obviously screen time will highly vary based on what you're doing with your phone. Just wondering if my below results are in line with the typical GNex phone. These results are with an Anker 2200 mAh battery. This is the phone pretty much just idling as it has been sitting unused since I got the Nexus 5, no network service anymore, I disconnected it from VZW.

11% @ 13hr8m in Airplane mode.
4% battery @ 1d5h42m on WiFi.

The 1d5hr run idling on WiFi, is it normal for the phone to be Awake almost constantly? Why is "Phone" showing 51% battery usage?
