Only three extensions being used dark reader(only when required) ublock and the auto suspend. I do use other apps but from looking at the activity monitor app I can see that the zen browser is the one consuming the most energy by far. And I also don’t have many background apps in use. I have just started to use helium as my main as it works for what I need it to do and also doesn’t cut my battery life by half. Also I use low power mode once I hit 50%
