How to Stop MacBook Pro Charging at 80

Understanding Why Your MacBook Pro Stops Charging at 80

Many MacBook Pro users notice their laptop stops charging once it reaches around 80 percent. This behavior isn’t accidental but part of Apple’s built-in Battery Management System. It helps extend the battery’s overall lifespan by preventing overcharging. Knowing why this happens is key to deciding if you want to stop this feature or keep it enabled.

What Is Battery Management on MacBook Pro?

The Battery Management System (BMS) learns your charging habits and adjusts charging accordingly. It aims to keep your battery healthy by limiting the charge to 80 percent under certain conditions. When your MacBook detects you’re plugged in for a long time, it might pause charging at 80 to help prevent battery wear.

How Does Charging at 80 Help Your Battery?

Charging only up to 80 percent reduces stress on the lithium-ion battery. Lithium-ion batteries degrade faster when kept at full charge for long periods. By stopping at 80, your MacBook prolongs its battery’s effective lifespan and maintains better performance over time.

Steps to Disable or Enable Battery Management Features

If you want to control whether your MacBook charges past 80 percent, you can adjust settings. Here’s how to do it:

Using System Preferences

1. Click the Apple menu and select System Preferences.
2. Choose Battery.
3. Click on Battery Health & Charging.
4. Uncheck the box labeled Manage battery longevity or Battery health management.

Disabling this feature allows your MacBook to charge to 100 percent without interruption, but it might reduce battery lifespan over time.

Using Terminal Commands for Advanced Control

Some users prefer terminal commands for more detailed control. Here’s a simple way:

1. Open the Terminal app from Utilities.
2. Type the command: sudo pmset -a battcharging 1 to enable or sudo pmset -a battcharging 0 to disable.
3. Press Enter and authenticate with your administrator password.

Note: Using Terminal commands should be done carefully as they can affect your system’s behavior.

Third-Party Tools to Control Charging

If you want more precise control over charging limits, third-party apps may help:

• Coconut Battery: Shows detailed battery information and allows limited control over charging thresholds.
• AlDente: A free tool that enables you to set a custom charge limit, such as 80 percent or 90 percent.

These apps require you to disable System Integrity Protection (SIP), which involves restarting your Mac into recovery mode and configuring settings. Be aware that modifying SIP can affect system security.

How to Install and Use AlDente

Follow these steps to set specific charge limits:

1. Download AlDente from a trusted source or GitHub repository.
2. Disable SIP if required, following instructions from the app’s documentation.
3. Launch AlDente and set your desired maximum charge (for example, 80 percent).
