How Does the Device’s Power Consumption Rate Affect the Duration?
The device’s power consumption rate directly affects the duration of its operation. A higher power consumption rate means the device uses more energy over time. For example, if a device consumes 10 watts, it will deplete its battery faster than a device that consumes 5 watts.
To understand this, consider the battery’s capacity measured in watt-hours (WHr). A 43 WHr battery can deliver 43 watts for one hour, 21.5 watts for two hours, or 43 watts for a shorter duration. If the device consumes 10 watts, you would calculate the duration by dividing the battery capacity by the power consumption.
The formula is:
Duration (hours) = Battery Capacity (WHr) / Power Consumption (W)
Using our example:
Duration = 43 WHr / 10 W = 4.3 hours.
However, if the power consumption decreases to 5 watts, the calculation changes:
Duration = 43 WHr / 5 W = 8.6 hours.
Thus, the relationship is clear: the higher the power consumption rate, the shorter the battery will last. Conversely, lower power consumption extends the duration of use. When assessing battery life, always consider these factors for accurate predictions.
