To find out how much of the battery life has been used, you can use the formula:
As a fun fact, battery technology has come a long way! In the early days of batteries, like the very first wet cell batteries invented by Alessandro Volta in the early 1800s, they could barely hold a charge for a few hours. Now, we have lithium-ion batteries that power everything from smartphones to electric cars, giving us significantly longer usage times!
