Comment on How can I find why certain apps are draining my battery (when they are not in use)?

I’m aware that there are lots of stuff active all the time but they indeed seem to have very little effect on the battery on this specific time interval. I just find it a bit weird that Firefox was that much active :}
And draining 35% in 18h means that my phone can last, at best, ~2 days (from full charce to 0), if I don’t use it at all.
More importantly it means that at night I must check that it have at least 15% or it will die out during the night (which will cause the alarm not to play).
Not the end of the world, I no, but still a bit weird, so I wondered is it normal or not, I think you are trying to say it is :)

Yeah, I was basically saying that it’s normal. “Normal” is relative, so there is that.
I don’t mean to sound pedantic, but I am just trying to cover all the nuances.
You are also thinking in raw percentages, which is confusing by its very nature. Generally, battery-app usage indicators measure from the last time they were fully charged so that will naturally skew what percentages actually mean.
If you use Firefox continuously and discharge the battery from 100% to 75%, Firefox will likely have used ~100% of the total power during that time. When the phone goes idle, the total battery usage percentage by Firefox will decline. So, if the phone is idle from 75% to 50%, Firefox now has only used 50% of the charge from 100% to 50% but still only 25% of the total charge. (I am just using percentages that are easy to calculate in by head, btw.)
When the phone is fully recharged again, the metrics should reset and percent usage indicators will fluctuate by future use.
