The life expectancy of a notebook battery is mostly based on the battery cycle count. Once that battery count has reached the limit set by the manufacturer. It is considered consumed, and although the laptop might still perform the same. Battery life might deplete rapidly, a clear sign it is time to replace that battery. In this post, we will show you how to find out what your Apple MacBook’s battery cycle count is. In this article, we are going to talk about How to Find Macbook Battery Cycle Count. Let’s begin!
How do you calculate a battery cycle?
A battery cycle count is calculation is based on the use of all the battery’s power. But not necessarily on a single charge. Such as, if your MacBook is charged at 100% and you use 50% of your battery. Then charge it back to 100%, then use another 50% of battery. It will equal to one battery cycle (50+50=100).
Likewise, if you use 20% of your battery then charge it back to 100% five times. It will equal to one battery cycle (20+20+20+20+20=100).
How to determine a MacBook’s battery cycle count
To find out what your MacBook’s battery cycle is, go to > About This Mac > System Report, and select the Power tab, under Hardware. In the right panel, you will find the Cycle Count.
What is your MacBook battery cycle count limit?
Knowing your battery count is great, but it does not help much if you do not know what your machine’s limit is. The limit is set by Apple and gives a good indication of the overall life expectancy of your battery. Compare the calculated cycle count to Apple’s limits set to specific machines to find out how your battery is fairing.
I have a 13-inch MacBook Air from mid-2011. And the maximum cycle count set by Apple is 1,000. As you can see above, I have reached 351 battery cycles or about one-third of the limit. So it seems that theoretically, my battery should still last a while longer.
Keep one thing in mind that battery count is always ready to give you an approximate idea of your battery life expectancy. Obviously, if your battery is performing poorly. You can always replace it even though you have not hit the limit set by Apple.
