How do phones check battery charge?
I was staring at my phone screen (after running out of ways to procrastinate) and a question sparked in my head! How do phones know how much battery is left? almost every phone has a little sign, and sometimes a percentage, telling you how much battery charge is left. I'm just a little curious, is all! :)

It's a math equation.The Capacity of a battery is defined in terms of Ampere Hour .
BLT= Capacity of battery / Consumption of the device= battery life.
