Stop or Limit MacBook Charging to 80 Percent

Table of Contents

Limit MacBook Charging to 80 PercentLike any other laptop, MacBooks have lithium-ion batteries that chemically degrade over time. The 20-80 percent is an ideal range for these batteries. And hence, you should avoid letting it charge over 80 percent or discharge to less than 20 percent.

Charging the battery to its maximum capacity causes chemical wear and tear due to high voltage and temperature. Other factors like battery cycles, too, determine the battery degradation.

Why Limit the Battery Charge on MacBook?

As mentioned, charging or discharging to the extremes stresses and degrades the li-ion battery. Hence, pushing it to charge from 80 to 100 will cause faster aging. It will reduce its charge holding capacity and may even cause it to swell in the long term.

So, if you prefer keeping the MacBook plugged in all the time for convenience, it would be a better option to limit the charging to between 65 to 80 percent using the methods given below.

Method 1- Limit MacBook Charging Using AlDente

AlDente is a popular application that limits the maximum charge level on Mac. These third-party apps can do so by modifying the “Battery Charge Level Max” (BCLM) parameter in the SMC. Here’s how to use AlDente on Mac:

Method 4- Optimize Battery Charging on MacBook

With macOS 10.15 Catalina, Apple introduced a Battery Health Management option to Mac laptops with Thunderbolt 3. When turned on, it would throttle the charging to reduce the premature wear of the battery.

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 the 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.

3. Then, check the box for Optimized battery charging.

It would have been great if Apple allowed users to set the maximum charge level manually. Anyways, you can always do it via the third-party apps mentioned above.

macOS Can’t Verify These Apps?

While trying to install or use the above apps, GateKeeper on macOS can show you errors like “macOS cannot verify that this app is free from malware” or “cannot be opened because the developer cannot be verified.”

To get rid of these warnings, either open the app from the right-click menu or go to System Preferences > Security & Privacy > General and click on Open Anyway. Here’s are ways to fix macOS can’t verify this app is free from malware.

Bonus- Check Battery Health and Cycle Count on MacBook

According to Apple, the MacBook battery is designed to retain up to 80 percent of its original capacity at 1,000 complete charge cycles. You can check your MacBook’s current battery condition and cycle count through System Report in macOS.
