How to reset macbook charge cycles. How to Check MacBook Battery Charge Cycles and Capacity
In this article, I will talk about how to know how many charging cycles your MacBook has already gone through and how much is the maximum possible charge (data table by model).
This article is suitable for all MacBook Pro and Air models released in different years. There may be some differences in the architecture or description of the Mac OS version.
When you use a Mac laptop, its battery goes through recharge cycles. Some recharge cycles are carried out using a full battery charge, which does not always mean one charge.
For example, one day the device could be used up to 50% charge, and then it was completely recharged. If this happened the next day, then it will not be two, but one recharge cycle. It turns out that one recharge cycle can take several days.
The battery operates for a limited number of recharge cycles, after which they exhaust their own resource. When the resource is exhausted, the battery must be replaced. It is possible to use the battery after the maximum number of recharge cycles has been used, but the battery life will be reduced.
Knowing the number of recharge cycles completed, the user can estimate the remaining number of cycles and then determine when to change the battery. To ensure optimal performance, the battery should be replaced when the maximum number of cycles has been reached.

How to find out the number of iPhone charge cycles
We look at the number of MacBook charging cycles
To view the number of charge cycles for your MacBook, you can use standard tools in the Mac OS operating system:
- Click on the bitten apple icon at the top, as in the screenshot below.
- In the list that appears, click on the “About this Mac” section.
- Then go to the “System Report”.
- Then you should switch on the left side to the “Power Options” tab.
- On the right there will be a section “Number of recharge cycles”. The number of cycles for the entire operating time of the MacBook battery will also be available there.
Maximum number of recharge cycles
Use the following tables to determine the number of charge cycles for your Mac battery. The battery life is considered exhausted when the number of charging cycles reaches this limit.
For MacBook:
For MacBook Pro:
For MacBook Air:
Old Apple computers were not equipped with such “hardy” batteries as they are now. The first computers could withstand approximately 300 recharges without loss of quality.

We determine the actual capacity of the Mac battery and the number of recharge cycles through a third-party application
To obtain extended information, you should use the third-party utility coconutBattery. We perform the following steps:
- Download the coconutBattery program from the official developer resource https://www.coconut-flavour.com/coconutbattery/ and install it on your Mac.
- Launch the installed software.
- A window will appear where the data will be presented, as in the screenshot below.
- If you click on "Mac info", you can find information about your computer.
- If you click on “Battery info”, the data will be displayed as in the screenshot below.
The coconutBattery utility has great functionality. You can use it to check the number of battery charging cycles on your iPhone.
Benefits of Apple lithium-ion batteries
Apple batteries can quickly charge up to 80% using fast charging mode, and then transfer to a slower, low-current charging mode. The time it takes to charge the battery to 80% depends on the type of gadget and its settings.
When the battery temperature exceeds the recommended values, the maximum charge level can be programmatically limited to 80%. With this combined process, your device will be ready for use again without any further delay. This option also significantly extends battery life.
Do you use a MacBook? Do you often work without being connected to an outlet, “on battery”? Then this information will definitely be useful to you. Friends, I myself am used to autonomy, so I often work wirelessly until the laptop dies. But alas, every year the MacBook holds its charge less and less, you have to get used to solving your problems faster (just kidding). Of course, ideally you need to change the battery, I wrote about this in a separate post. But on the other hand, many people don’t know how to generally check the condition of the Mac’s battery, or what its service life is. So today I will tell you how to do it yourself.
So, to check the battery status, you do not need to resort to separate programs - the macOS system makes it easy to cope with this task. To do this, click on the apple in the corner of the screen, select “About this Mac”.
Then click the “System Report” button.
In the system window that opens, select “Power” from the list on the left. We are specifically interested in these indicators: “Number of recharge cycles” (Cycle Count), “Condition”, and “Full Charge Capacity (mAh). Have you checked? Let’s move on.
I saw articles on the Internet that described how to check the number of recharge cycles, but there was not a word about the full capacity of the battery (and its remaining capacity). But in fact, this is a very important indicator, because the number of cycles may be small, but the MacBook sits down very quickly, and in the meantime you will be wondering what the reason is.
There are several options here. The first is if you left the laptop “idle” for a long time, that is, it lay completely discharged for a long time, but idle time is fraught with a slow “dying of the battery.” The second case, if, on the contrary, you were constantly working from the network, then the battery ceases to function normally, since its “services” are not in demand. Well, thirdly, probably the most obvious - you can “kill” the battery, or the one whose output power does not match your version of Mac. You can find out the factory (initial) battery capacity of your particular model on the official Apple website. After that, compare this indicator with yours and a lot will become clear.
And now about recharge cycles. If you use your MacBook in normal mode, that is, both on mains power and on battery power, then the number of recharge cycles is usually a fairly accurate indicator. All MacBook batteries (except some before 2010) are rated for 1000 cycles. This is the battery life declared by the manufacturer, after which it may become completely unusable.
But note that the battery life will begin to drop much earlier; this can be replaced from about the three hundredth cycle. Therefore, you can “torment” the battery for up to 1000 cycles or more, but there will be little pleasure from this. Here you will have to choose, if you need a laptop that works for as long as possible without recharging, you will have to change the battery. And I wrote about how to preserve your Mac battery for as long as possible
Most modern Apple laptops go through 1,000 charge cycles before they need to replace the battery. Below we will tell you how to check the number of charge cycles of a MacBook Pro or other model.
Apple's support document explains how your MacBook calculates the number of charge cycles:
The recharging cycle is completed when you fully charge the battery, but this does not always require a complete discharge. For example, you can use only half the charge in a day, and then fully charge your laptop. The same can be done the next day and it will count as one recharge cycle rather than two. Sometimes it can take several days for the cycle to complete.
How to find out the number of charge cycles on a MacBook
- Select the Apple icon from the menu bar.
- Now select About itMac, and then System report.
- From the menu on the left, select Power supply.
Number of recharge cycles for MacBook Pro - Number of recharge cycles will be in the section Information about the degree of serviceability.
Under the number of cycles you will also see the battery status. If the recharge cycles are more than 1000, most likely maintenance is required, i.e. battery replacement.
Using the above method, you can find out the number of recharge cycles for MacBook Air, MacBook Pro and other models. Now you know how many battery recharge cycles your MacBook has completed, and you can act on that information.
Has your Mac, which has served faithfully on trips for many years, suddenly begun to let you down - running out of charge earlier than it should? Most likely, the problem is in the battery - it has already outlived its usefulness and needs to be replaced. How to check it and replace it in time in the future?

What is a "recharge cycle"?
This is when you discharged the battery to zero and then charged it to 100 percent. In real life, this “ideal” option does not always work. Example: you work part of the time at home and part of the time in the library (where, of course, the outlets are a problem, so you have to work on battery power). You discharge the battery to 50%, and then come home and charge the battery again to 100%. This means that you have completed only 0.5 recharge cycles; you will only be able to complete it completely - in the same scenario of using the MacBook - only the next day. For some, the battery works at 25% per day (i.e. it will take 4 days), for others at 10% (10 days), and so on.
Each recharge cycle slightly reduces the battery capacity. Apple notes that the capacity will drop to 80% of the original after 1,000 full charge cycles, and then worse.
How to find out how many recharge cycles have already passed
1
. Click on the Apple menu (“” in the upper left corner of the screen).
2
. Select an item About this Mac.
3
. In the window that appears, click on the button System report... .
4
. In chapter Hardware select Power supply.
5
. Look at the number to the right of the inscription Number of recharge cycles.
As you may have guessed, everything less than 1,000 is good, everything more is bad. I have a 2013 13-inch MacBook Pro at work, and in 1.5 years I've only completed 103 full charge cycles. Enough for me and the next owner of the “proshka”.
A necessary addition: old Apple laptops were equipped with not so “hardy” batteries. The first Macs could withstand only 300 reloads without loss of quality! You can check your MacBook using a special Apple table:
If everything is fine with the number of recharge cycles, but the MacBook battery still discharges quickly, it is quite possible that it is defective. If the warranty is still valid, contact the selling company for a free replacement.
