I've been running these tests on and off for months with different browsers. On my Pixel 8 Pro, the different Firefox variants are all more or less the same (which is to say tremendous battery hogs). I also tried with Ublock Origin enabled and it didn't make an appreciable difference.
Tests on however many devices you're comfortable with would be super appreciated!!
do you get any meaningful difference in the browser engine family? Like between Chromium, Brave and Vivaldi for example?
All those examples are Chromium derived, and all have more or less identical battery characteristics. Some may score slightly higher on benchmarks than others, but they all consume roughly the same amount of power.
I made a tool to measure the battery impact of different Android web browsers - here's what I learned!
Howdy, Android nerds!...
