"Anecdotes aside, let's find some data:"

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.

Nexus 4 was released 2012 while Nexus 5 in 2013.

Believe me, batteries and power management on Android has improved since 2013.

Nexus 5x vastly improved battery life over the 5.
