It has been a tad over 18 months since I have been using MacBook Air (2017 model). Of course, the battery backup has dropped. That said, it still lasts around 6-7 hours on a full charge with normal usage. The decreasing performance of the battery meant that I had to check the battery condition and also find out the battery cycle count on my Mac as it is a major factor indicating battery health. If you are wondering what does battery cycle count mean then you’ll get the explanation here along with how to check it out on MacBook Air or Pro.
What Is Battery Cycle Count?
A battery charge cycle happens when you drain and recharge the battery. Simple enough? But there’s a catch. The total charge percentage has to be 100% to be counted as one complete cycle. So, if you charge your Mac from 80% to 100% that’s not a cycle, instead, it’s only 20% of the cycle. The percentages can be different and as soon as they amount to 100, it will be counted as a cycle.
Every battery comes with a predetermined number of charge cycles. Once those number of cycles are reached or consumed then it’s recommended to replace the battery. You may continue using it if you wish but you’ll have to live with poor battery life.
Charge Cycles Limit
All of the MacBook’s Air or Pro launched after 2010 have a maximum battery cycle count limit of 1000. For earlier versions, the limit is 500 and can even go as low as 300. So, if you own a recent version of Mac and have a charge cycle less than 1000 then it can be considered a good cycle count and your battery is in good shape.
Now, then let’s find out the battery cycle count.

Alternatively, you can hold down the option key and click on the Apple icon. This time you’ll a different option in the menu. Select System Information.

In my case, it turns out to be 353 which is well under 1000 hence the condition is normal.
