1893012 - Telemetry probe for battery consumption while Fenix is in the foreground.

Status: NEW

(Firefox for Android :: Performance, enhancement)

Description

[Marc Leclair [:mleclair]]

Right now , there is not much understanding on how much power we consume on android. This probe would allow us to look into how much battery we drain every X seconds (up to us to decide, I think 15 seconds is a good starting point).

I propose we use the android api that offers a battery counter in nanowatt hours which is somewhat accurate. This counter will decrease before the phone battery % decreases (at least on my s21 and pixel 6). For instance, on my S21, I would get a reading of 268000 -> 267990 -> 267973 , etc... before it moved from 66% to 65%.

WIP with three different ways of doing it. Tried to tie it to the application lifecycle
Added a marker for battery consumption as well.
