Many people prefer to keep their MacBook plugged in all the time. However, this negatively affects battery life. While it’s normal for the MacBook’s battery to deteriorate, you can extend its life by limiting the charge percentage in macOS. In this article, let’s look at different methods to limit or stop MacBook charge to 80 percent or another level.

Like any laptop, MacBooks have lithium-ion batteries that chemically deteriorate over time. The 20-80 percent is an ideal range for these batteries. And that’s why you should avoid charging it more than 80 percent or discharging it to less than 20 percent.
Charging the battery to its maximum capacity causes chemical wear from high voltage and temperature. Other factors, such as battery cycles, also determine battery degradation.Why Limit Battery Charge on MacBook?
As mentioned before, charging or discharging to the limit loads and discharges the Li-ion battery. So if you charge it from 80 to 100, it will age faster. It reduces the ability to hold charge and can even swell in the long run.
So if you prefer to keep the MacBook plugged in at all times for convenience, a better option is to limit the charge to 65 to 80 percent using the methods below.Method 1- Restrict MacBook Charging with AlDente
AlDente is a popular application that limits the maximum load level on Mac. These third-party apps can do this by changing the “Battery Charge Level Max” (BCLM) parameter in the SMC. Here’s how to use AlDente on Mac:
1. Download al dente via the link below.
2. Open the dmg file and drag it into Applications.
3. Click the app icon in Applications. You can also open it from the Launchpad.
4. Tap Open when the message “Are you sure you want to open it?” warning appears.
5. The app will now prompt you to install a Helper tool to control MacBook charging behavior.
6. Click OK. Then enter your MacBook password and tap Install Helper.
7. Next, go to System Preferences > Battery > Battery on your Mac.
8. Uncheck the box for Optimal battery charging and click Disable.
7. AlDente will now appear in the menu bar at the top. Set the percentage to which you want to limit your load.
Here we set it up to prevent the MacBook from charging to 80 percent automatically. Once the set percentage is reached, the MacBook will say “Battery not charging” and stay at that specific level.
You can explore other options in tweak in the AlDente settings. However, most require the Pro version. You can enable or disable AlDente at any time by clicking the Power icon in the app settings.

BatteryStatusShow is a similar application for limiting charge. However, it comes in a portable version, which means you don’t need to install it. All you need to do is open the downloaded app, make the changes and you’re good to go.
1. Download BatteryStatusShow via the link below.
2. Click on the downloaded BatteryStatusShow.app to open the app.
3. Once the app is open, click Change next to the charge level.
4. Drag the slider to 80% or any other level where you want your MacBook to stop charging.
5. Now click on the gray OK button.
6. Then enter your device password and tap OK.

Like AlDente, Charge Limiter is an open source application to prevent MacBook from automatically charging above a certain level. Follow the steps below to use it.
1. Download Charge Limiter on your MacBook via the link below.
2. When you open the app for the first time, GateKeeper will stop you because the app is not code signed. To get around this warning, right-click on the app and select Open.
3. Once it opens, enter the load limit. To limit charging to 80 percent, enter 80. Click OK.
4. Enter the Mac password and click OK.
The Charge Limiter now limits the maximum charge level of your MacBook. If your battery is currently at a higher level than the set level, unplug the charger. Once it falls below the set level, plug it back in.

With macOS 10.15 Catalina, Apple introduced a Battery Health Management option for Mac laptops with Thunderbolt 3. When enabled, it would delay charging to reduce premature battery wear.
Later, on macOS 11 Big Sur, Apple added “Optimized Battery Charging,” which learns your daily charging routine and tries to keep the battery at 80 percent by delaying charging. The same feature has been carried over to macOS 12 Monterey.
To enable optimized battery charging on MacBook:
1. Click the Apple logo at the top left. Select System Preferences.
2. Then click on Battery and select Battery from the sidebar.
3. Then check the box for Optimized battery charging.
However, the feature can be finicky at times. Because it learns based on how you charge the MacBook, it may not always limit the charge to 80 percent, leading you to believe that optimized battery charging won’t work on your MacBook.
It would have been great if Apple allowed users to manually set the maximum charge level. Anyway, you can always do it through the third-party apps mentioned above.macOS can’t verify these apps?
While installing or using the above apps, GateKeeper on macOS may display errors such as “macOS cannot verify that this app is free from malware” or “unable to open because the developer cannot be verified”.
To get rid of these warnings, open the app from the right-click menu or go to System Preferences > Security & Privacy > General and click Open Anyway. Here are ways to fix macOS that cannot verify that this app is free from malware.Bonus – Check Battery Status and Cycle Count on MacBook
According to Apple, the MacBook’s battery is designed to retain up to 80 percent of its original capacity on 1,000 full charge cycles. You can check your MacBook’s current battery status and cycle count through System Report in macOS.
All you need to do is click the Apple icon in the menu bar and select About This Mac. Then click System Report. Select Power and check the Battery Status column to see the battery’s condition and how many times it has been fully charged.
We’ve written a detailed article on how to check battery health on the iPad, explaining what battery cycle count is and why it’s important. Moreover, you can use the mentioned third-party apps to monitor the health and cycle count of your MacBook battery.To block
