How to check your MacBook's battery health

Every device, such as a MacBook, MacBook Air, and MacBook Pro, benefits from a limited number of cycles until a battery is used up and needs replacing. As a Mac battery gets older, the time in-between full charges reduces. This means that you aren’t getting as many hours of charge as you would have when it was new. 

Once a battery hits its maximum number of charging cycles, it can still be used. But it does mean that you might only get a couple of hours at most of use until it needs charging again. In some cases, you might not be able to use a Mac without a power cord. This is clearly a sign of a dead battery. 

So, to avoid this happening unexpectedly, let’s first look at what a battery cycle is and how to check your current battery status. 

Find the battery icon in the upper right corner of your Mac and right-click on it. From the start, there is lots of interesting here:

What is Mac battery cycle

The specified amount of maximum battery cycles indicates how many full charge-discharge cycles your battery can take while retaining 80% of its capacity.

On most modern MacBooks, that number is 1000. Think that’s not enough?

Think about how you normally use your Mac. 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?

In that case, it’s getting fully charged but not using any of that charge. It could take years for it to reach the maximum number of cycles possible. 

However, if you charge the Mac before going somewhere — until the charge reaches 100% — and then you take your Mac without the plug, and it uses 50% of the charge, and then you do the same the following day, this is one full cycle. It would only count as two if the charge went down to zero and needed full recharging again on both occasions. 

So, every time you use as much of the battery as possible and then recharge it, this is a complete battery cycle. 

How to check my Mac battery cycle count

Now that you understand what a Mac battery cycle is, we can have a look at how to check this. 

How much charge a Mac currently has is automatically displayed in the top toolbar, and it is shown as a percentage. When clicked on, it will give you the option to open Battery Preferences. It also displays what is currently using a large amount of the battery charge.

Now, here is where to check how many charging cycles your Mac has remaining:

  1. Go to Apple () menu in the top toolbar (you can also search for System Information using Siri, or Spotlight Search).
  2. Click on About This Mac > System Report.
  3. Within the Hardware section, navigate to Power.
  4. Listed under Health Information is the current Cycle Count. It also provides the Condition status of your battery.

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

How to test MacBook battery

On-screen indicators are different from real life. If your battery promises 2 hours of remaining time, it’s not hard to wait and see if that holds true. That’s the most straightforward MacBook battery test. Reality: battery meters always overestimate.

On newer macOS versions, there is a whole section in System Preferences dedicated to battery health.

Go to System Preferences > Battery > Battery health…

See that checkmark next to “Manage battery longevity”? If you uncheck that setting, your Mac will probably run a bit longer on a single charge, but that will sacrifice the battery life in the long run. That’s another way to test MacBook Pro battery. Charge your battery to 100%, and then use your Mac with that setting enabled to notice what changes.

Does my Mac model make a difference? 

Yes, it does. Depending on how old your Mac is, some models have different amounts of cycles than others. As a general rule, older Macs are not as energy efficient as modern models, so these usually have much shorter total battery cycles. 

Based on information from Apple, here are the various models of MacBooks, MacBooks Air, and MacBooks Pro and their battery cycles: 

  • MacBook Pro 2009-2022 (most models): 1000 cycles
  • MacBook Air (2010-2022): 1000 cycles
  • MacBook (2009-2017 models): 1000 cycles 
  • MacBook (13-inch Aluminum, Late 2008): 500 cycles 
  • MacBook (all earlier models, except the one above): 300 cycles
  • MacBook Pro (15-inch Late 2008): 500 cycles
  • MacBook Pro (every other 2008 model): 300 cycles

We hope this is useful. Now, you know how to check current battery percentages, how many battery cycles your Mac has, and where to find that real-time data. Below are a few quick ways to improve the battery health of your Mac. 

How to improve Mac battery health? 

1. Use Energy Saver mode

  • Open System Preferences (via Apple () menu, Siri or Spotlight) > Click on Battery. 
  • Switch on Battery and check the box for Low power mode.
  • Do the same upon switching to Power Adapter. 

2. Switch off or delete power-draining apps 

  • Open CleanMyMac X (you can download a free edition here).
  • Use the Optimization > Heavy Consumers to identify battery-draining apps. 
  • Close the ones you don’t need or click on Uninstaller to remove the apps you don’t use anymore.

3. Reduce screen brightness 

Brighter screens use too much power. 

It is always going to be a balancing act between too bright and not bright enough. Other factors, such as light from external sources, what you are doing at the time, and internal lights, will also impact how bright or not the screen feels. 

To change the brightness, go to System Preferences (either through the top toolbar Apple icon, Spotlight, or Siri) and click on Displays. Use the Brightness slider to adjust this. Or you can use the F1 and F2 keys on MacBooks (F14 and F15 on desktop Macs). 

4. Update your macOS software 

When you update to the latest version of macOS software, newer versions often include the latest in battery-saving technology. Every time an update happens, Macs that upgrade to the newest version experience improved efficiency and faster processing power. 

Before downloading a new macOS, make sure to back everything up first. To update, click on Apple icon in the top toolbar and select About This Mac > Software Update (it will always show you if a new update is needed). 

5. Close background apps

Launch Agents are small background applications that are normally hidden. Still, they can be primary battery drainers on your Mac. It can be equally useful to keep the number of Launch Agents and Login Items to a minimum, which CleanMyMac X can quickly and easily tidy up:

  1. While you are in CleanMyMac, click Optimization > Launch Agents.
  2. Disable everything to a bare minimum.

Getting the most out of your Mac battery keeps it going for longer. You can do more with a Mac that has a healthy battery. To keep it healthy for as long as possible, we recommend making sure your Mac is running as efficiently as it can. 

CleanMyMac X is a valuable tool for getting your Mac up and running as good as new. It can monitor the health of your Mac, clear out system junk, remove viruses, and tidy up long-forgotten folders and files. Everything you do that improves performance will reduce the strain on the battery keeping it running for longer.
