Finally got to order a 16GB Nexus 4

The consensus seems to be that Wi-Fi is easier on battery than mobile data (3G, HSPA, 4G LTE). I want to check it out just by how much on my Nexus 4. On my Nexus 7, adding a SIM did measurably impact the battery drain (i.e. faster drain).

Is there any reading material I can find on this topic, written in an analytical/scientific manner?

That makes sense actually, if I look at both our graphs. I don't have data only wifi and I was doing a bit better on battery life. It seems if you have data and wifi disabled the battery life probably doubles or even triples. I'll have to try it for fun.

Cell tower radio strength varies quite a bit, wifi not as much which is probably the main reason why it's better for battery.
