How Battery Life is Calculated

This calculator provides a simple estimate of a battery's life by dividing its capacity (in milliampere-hours) by the current consumption of the device (in milliamperes). This gives a theoretical runtime in hours. It's important to note that real-world battery life can be affected by factors like battery age, temperature, and discharge efficiency, so this calculation should be used as a guideline.

Formula: Battery Life (hours) = Battery Capacity (mAh) / Current Consumption (mA)
