It’s helpful to know how many cycles most Mac models have. The current Cycle Count it displays is how many cycles are remaining until the battery has reached its maximum.

Now that you understand what a Mac battery cycle is, we can have a look on how to check this. So every time you use as much of the battery as possible, then recharge it, this is a complete battery cycle. It would only count as two if on both occasions the charge went down to zero, then it needed fully recharging again.

And then you do the same the following day, this is one full cycle. However, if you charge the Mac in before going somewhere - until the charge reaches 100% - and then you take your Mac without the plug and it uses 50% of the charge. It could take years for it to reach the maximum number of cycles possible. In that case, it’s getting fully charged, but not using any of that charge. Do you work from the same desk, plug it in, keep it charging all day, then close it down and not use it until the next day? Think about how you normally use your Mac. On most modern MacBook that number is 1000. The specified amount of maximum battery cycles indicates how many full charge-discharge cycles your battery can take, while retaining 80% of its capacity. From the start, there is lots of interesting here: What is Mac battery cycle So to avoid this happening unexpectedly, let’s first look at what a battery cycle means and how to check your current battery cycle.įind the battery ? icon in the upper right corner of your Mac and right-click on it.

This means, you aren't getting as many hours of charge that you would have when it was new. As a Mac battery gets older, the time in between full charges reduces.

In my experience, the first 300 cycles on my MacBook Pro took about 2 to 3 years of pretty heavy use (you can keep track in the System Information app, under the Power section). Or Going 100% to 50% twice.įor comparison, the older batteries (and to my knowledge, most non-Apple batteries) were rated for 300 cycles. One "cycle" is a full discharge and recharge - so going from 100% to 0%. The built-in battery of your MacBook Pro or MacBook Air is designed to deliver up to 1000 full charge and discharge cycles before it reaches 80 percent of its original capacity. It's also worth noting that Apple has improved battery durability considerably over the past few years (I think ever since they went with the "non-removeable" batteries). If I were you, I'd spend the extra $30 and have Apple do it.
