How to Calculate the Battery Run Time?

It would be fantastic if you never had to charge your smartphone again. However, you're undoubtedly well aware that no battery lasts indefinitely. This battery life calculator uses the following algorithm to calculate the approximate runtime of your battery

Battery rumtime = capacity/consumption * (1 - discharge safety)

  • where, Capacity refers to the ampere-hour capacity of your battery. This value is typically displayed on the back of the storm.
  • The average current draw of your electronic equipment is measured in amperes and is referred to as consumption
  • The percentage of your battery capacity that is never used is referred to as discharge safety. If you're using a LiPo battery to power a drone, for example, you should never discharge it below 20%, or it will be damaged. Our battery life calculator defaults to a 20% discharge safety, but you can alter it as needed.

What is the battery life in sleep mode?

Let's pretend you're creating an IoT device that spends most of its time in sleep mode. In this instance, you'll probably want to figure out how long a battery will survive. To find out, simply go to advanced mode. You can alter the following extra parameters in advanced mode:

  • Awake time is simply the amount of time your gadget is awake throughout one operational cycle, such as 2 seconds.
  • The average consumption of your device in sleep mode, measured in amperes, is called consumption in sleep mode. This figure is most likely significantly lower than the consumption while awake.
  • Sleep time refers to the amount of time your gadget sleeps during a single operation cycle.

The battery life calculator uses the equation to calculate the average usage based on the values provided above.

(consumption1 * time1 + consumption2 * time2) / (time1 + time2) = average consumption

The awake mode is represented by index 1, and the sleep mode is defined by index 2. After determining the average usage, our calculator plugs into the standard battery life calculation to calculate the battery's runtime.

FAQ’s on Battery Life Calculator

1. How many hours does 6000mah battery last?

The operating time of a battery is interdependent with the amount of current drawn from it, so the number of hours that you get will be affected by the amount of energy used. A 6000 mAH battery can theoretically provide 1000mA for 6 hours, 6000mA for 1 hour, 100mA for 60 hours, and 10mA for 600 hours.

2. What battery is in a calculator?

The most common types of batteries for calculators are standard AAA and coin cell batteries, but the packaging or instructions for your device will tell you which type you need.

Moles = mass of the substance in grams/molecular weight.

3. How do you calculate battery usage?

The Formula to Calculate Battery Run Time is (10 x battery capacity in amp hours) divided by (appliance load in watts).

4. How do you calculate how long a battery will last?

To determine how long your battery will last, calculate the battery's total capacity and divide it by your circuit's power. Multiply the battery's reserve capacity by 60. With a reserve capacity, for instance, of 120: 120 x 60 = 7,200.
