There are some important variables missing in your little math equation my friend. The most important of which would probably be things like display brightness... which has a huge effect on percentages reflected and recorded in your batterystats.bin file...
Here is a hypothetical to think about....
You charge your device entirely.... it sits on standby for 3 days without being used or touched. It drains on standby to 20%...
You then pick it up and you use it for an hour until it dies with it at 45% brightness (just an example, totally irrelevant number to this equation)... right before it dies your battery stats read something like this...
Display 23% or something like that
The rest is irrelevant.. that number is what is confusing you...
Does 23% mean you had the display on for 15 hours for that 72 hour time frame? Of course not. Because output of power effects how long the display will be able stay on.
Like your car gets 25 miles per gallon right? Unless you drive around town in 1st gear every where you go, wasting fuel and running the engine at redline.
I don't quite understand how this concept is so confusing.
Your math was perfectly correct. But you aren't in the right class. This is physics, not just math. Lol
Wow too long too lazy to read this is why I failed physica xD
