I would like to know how do electronics (ie smartphones,mobilephones,laptops etc) know exactly what % of juice is left in the battery and how long that juice is going to last. Thank you in advance

Question: How to accurately calculate battery % left?

What is the minimum amount of current that these sensors can sense? The current i would like to measure would be between 5mA to 10A or even more.
