Battery Health

Okay so as much I noticed in this app on different devices that the battery health, no matter how old or new the device, is always "good", not excellent or bad but only good. Other than that, it really helps when I wanna know temp. And I don't really understand the concept of voltage shown.

It gives a very broad picture..i think details are missing like the charging cycle should be measured in decimals cause i charge from 20-80 every time it increases 1 charging cycle but it shouldn't...the dev worked good on how clean it looks and how good the ui feels but the battery health should not be graded like excellent good bad but should be more accurate or best % wise. ik it requires funds but good luck

I have a suggestion, you should tell users the remaining mah of battery capacity, as most of the users who are looking for information about their phones battery health aren't looking for the word good or bad, they want specifics as to how the battery mah is reduced reletive to when it was new.
