Looks like Apple is middle of the pack among premium phones these days. My experience was with NEXUS 4 and 5, which would often be out of juice when I needed them.
FWIW: I think it's pretty sad that almost all of these phones are certainly collecting this data (even if only in internal dogfood populations, etc), but then the stats we get are based on random things like "talk time" or ...
I wonder if anyone started a public app project that auto-tracks and uploads battery stats that folks can participate in.
