How To Find The Cycle Count Of Macbook Battery

Previously, if your laptop battery began losing power, you’d know by looking at your computer and seeing “time remaining: 16 hours” that it was now running on a total of one-seventh of its original charge. But modern battery technology is much more accurate, meaning you’ll only know exactly how many hours you have left with a smart laptop tracker like Osram.

What is Battery Cycle Count?

A battery cycle is the basic discharge during which it’s voltage drops below a level of peak charge. Batteries have different number of volt drop cycles they can go through before they are considered spent. If a laptop battery has reached 500 cycle count, then it would be better to replace the battery as batteries lose their efficiency over time.

Many types of energy and power sources have a given number of cycles. A full battery discharges from 100% to 0%. In each iteration, the power source will hover around 100% for a little while until it self-powers down to its lowest point. The battery cycle count is the sum total number of full discharges the battery goes through during its lifetime.

To find the battery cycle count you will need to pull either up on the computer’s keyboard and type “charge”, then click on the indicator for time remaining. You should now see a display saying how many active cycles are left in the battery.

How to Calculate Battery Cycle Count

The number of times a device has finished charging/discharging is called the cycle count. Generally for an electronic device like a laptop, the higher the cycle count this means that it is more likely to have better battery life.

What is the cycle count of my MacBook battery?

There are different ways to calculate a MacBook’s battery cycle count. One way is to find out the number of charging cycles your Mac has done in the past year and call that the number of discharge cycles. But, there are some input values that have to be known in order to perform this calculation – voltage, age time of last charge, hours used per week and the power consumption rate.


Usually, lithium-ion batteries have the battery cycle count right in the name. Laptops generally last around three years, and
before that point date, test the laptop’s battery to see if it is still keeping a charge.

One of the first things that you need to do is identify your current battery cycle count, otherwise known as the life of your battery. For example, if you’ve had your laptop for 1 year, then you’ve got an estimated 1,000 cycles on it. This means that every charge and discharge of the battery will take up a period of a thousand days or about one year. Once you have this number, simply divide it by roughly how fast your battery drains power in a day which is in watt hours.

Checking your iPhone battery to see how much you can use it before needing to plug in. The number of cycles is a representation of how high the voltage will be and how fast the rate at which it is discharged current reaches 1 ampere. Cycling keeps the battery in good health by ensuring that a continuous flow of current passes through it instead of sudden, shoddy bursts that can ruin the connection between the cell plates and harm the battery’s chemicals.
