App Store Description
Battery life refers to the length of time a device can operate on a single charge. Common methods for calculating battery life involve estimating based on the device's battery capacity, power consumption, and efficiency.
In this example, we assume the battery capacity is measured in mAh (milliampere-hours), flashlight power in watts (W), and efficiency as a percentage (%). The formula for battery life calculation is:
Battery life (hours) = Battery capacity (mAh) / (Flashlight power (W) * Efficiency (%))
