Understanding the Importance of Battery Percentage
Before we dive into how to add battery percentage to your MacBook, it’s essential to understand the importance of keeping track of your battery health. A MacBook’s battery is its most valuable component, and improper use can lead to reduced performance, decreased battery life, and even damage to the battery. To ensure your MacBook runs smoothly and efficiently, it’s crucial to monitor its battery percentage regularly.
Prerequisites:
Before we begin, make sure your MacBook is:
- plugged in

Step 1: Check Your Battery Percentage
To check your battery percentage, follow these steps:
- Launch System Preferences: Click the Apple logo in the top left corner and select System Preferences.
- Battery: Click on Battery in the left-hand menu bar.
- Percent: Your battery percentage will be displayed below the battery icon.
Table:

| 20-50% | Sleep mode | 4-8 hours |
| 50-80% | Sleep mode | 6-10 hours |
| 80-100% | Sleep mode | 10-15 hours |
Step 2: Turn Off Your MacBook
To add battery percentage, you need to disable power management features to allow the MacBook to use the entire battery life. Follow these steps:

Step 4: Run the command to update battery percentage
To add battery percentage, you need to run the following command:
