Where the Power Goes
Measure current and find the big drains.
The Battery Budget
A battery holds a fixed amount of energy. To run for months, you must understand exactly where every drop of power goes. 🔋
Measured in Milliamps
Power draw is measured as current in milliamps (mA). A board pulling 80mA from a 2000mAh battery drains it in just about a day.
