Battery Drain Time Calculator

Formula

The formula to calculate the battery drain time is:

\[ \text{T} = \frac{\text{C}}{\text{P}} \]

Where:

\(\text{T}\) is the battery drain time (hours)
\(\text{C}\) is the battery capacity (mAh)
\(\text{P}\) is the power consumption of the device (mA)

What is Battery Drain Time?

Battery Drain Time refers to the duration a battery can last before it is completely discharged or drained. It is determined by the battery’s capacity and the power consumption of the device it is powering. The higher the device’s power consumption, the shorter the battery drain time. This concept is crucial in devices like smartphones, laptops, electric vehicles, etc., where battery life significantly impacts the user experience.

Example Calculation 1

Let's assume the following values:

Battery Capacity (C) = 3000 mAh
Power Consumption (P) = 500 mA

Using the formula:

\[ \text{T} = \frac{3000}{500} = 6 \text{ hours} \]

The Battery Drain Time is 6 hours.

Example Calculation 2

Let's assume the following values:

Battery Capacity (C) = 4000 mAh
Power Consumption (P) = 800 mA

Using the formula:

\[ \text{T} = \frac{4000}{800} = 5 \text{ hours} \]

The Battery Drain Time is 5 hours.
