1. Click the Apple logo () → System Settings.
   
   
2. Navigate to Battery.
3. Access the drop-down menu against Low Power Mode.
   
   
4. Select Always.
   
   
5. Enter your system’s username and password when prompted.

1. Click the Apple logo () → About This Mac.
   
   
2. Select More Info.
   
   
3. Scroll to the bottom in the About menu and hit System Report.
   
   
4. As the new window appears, choose Power.
5. Here, under Health Information, you will find detailed information about your MacBook’s battery health, cycle count, and maximum capacity.
   
   
6. Pay attention to the Condition parameter. You’ll see any one of the following:
   • Normal: Your MacBook battery is doing fine.
   • Replace Soon: The battery is working but holds less charging capacity than before.
   • Replace Now: The battery is completely degraded and must be replaced urgently.
   • Service Battery: The battery is not authentic or poses harm to the system. It must be replaced as soon as possible.
7. Based on the alert, you must act accordingly.

Note: On average, a Mac can go swiftly through 1000 charge cycles. This also should give you some idea about the battery condition of your MacBook.

By monitoring these metrics regularly, you can identify any potential issues with your battery that may cause excessive drain.

4. Manage power adapter preferences

Occasionally, I leave my MacBook on charging and forget about it, so the device remains up until I return. This carelessness can severely harm the battery of your MacBook.

However, you can prevent such abuse by changing your MacBook’s power adapter preferences.

1. Go to Apple logo () → System Settings.
   
   
2. Select the Lock Screen menu.
   
   
3. Now, set the Turn display off on power adapter when inactive in a way that is optimal for you.
   I have set it for 3 minutes.
   
   
4. Enter your system username and password → Click Modify Settings.
   
   
5. This will allow you to extend your MacBook’s battery in case of emergencies.

 In my opinion, it is a small but essential personalization factor that poses many advantages.

5. Disable Power Nap (Only for Intel-based Mac)

Users who are experiencing MacBook battery drain in Intel-based Macs can address this issue by disabling Power Nap.

When enabled, this feature regularly updates background activities like fetching emails or updating iCloud files. However, it can significantly impact battery life. To disable this:

1. Go to Apple logo () → System Settings.
   
   
2. Access Battery menu → Click Options to proceed.
   
   
3. Finally, set Enable Power Nap to Never → Done.
   
   

This will prevent your MacBook from performing these tasks when it’s in sleep mode and help conserve battery power.

6. Customize Display settings

Adjusting your display settings can turn out to be beneficial when you’re experiencing a major battery drop on your MacBook, even when not using it. 

1. Access Apple logo () → System Settings.
2. Select the Displays option.
3. Here, you can change the settings according to your preferences.
   
   

If you want to reduce power consumption using display settings on your Mac, here’s what you need to do:

• First, dim the screen brightness to a level comfortable for you. This alone can improve the battery life of your Mac.
• If desired, you can enable Automatic adjust brightness to let your MacBook adjust the brightness according to ambient lighting conditions as needed.
• You can even enable Night Shift mode on your Mac. It will automatically adjust the colors of your display to a warmer tone at night.
• Moreover, consider enabling dark mode whenever possible as it uses less energy compared to light mode.

With these display customizations in place, your MacBook will optimize energy and consume less battery effective immediately.

7. Disconnect Bluetooth accessories

Disconnecting these accessories when not in use can help preserve battery life. To do so,

1. Access Bluetooth settings on your Mac.
2. Now, you can either turn off Bluetooth or disconnect any paired devices.
   
   

In case you’re using add-ons like AirPods, unpair them when you’re done. This will avoid automatic pairing when such devices are near your Mac.

Moreover, if you’re fond of using Bluetooth accessories like a mouse or keyboard, disconnect them while not in use. We often tend to leave the devices connected and run out of battery for both the Mac and the accessory.

8. Disable Startup apps on Mac

Another practical solution to fix MacBook’s battery drain issue is to disable startup apps. When a MacBook starts up, it usually launches several applications simultaneously, contributing to unnecessary battery consumption.

However, you can take control of this occurrence and disable some of these apps. But be cautious while undertaking this process so you don’t disable necessary system software or essential utilities required for the device’s operation.

By disabling the redundant startup apps, your MacBook can conserve battery for longer periods without compromising functionality. It may look like a simple adjustment, but it will help you manage the power of your MacBook in the long run.

9. Enable Optimised Battery Charging on Mac

Charging habits also play a prominent role in managing the overall health of the MacBook battery. Hence, use the Optimized Battery Charging feature to slow down the aging process of the battery and maximize its lifespan.

To enable Optimized Battery Charging on your MacBook,

1. Navigate to the System Settings.
2. Access Battery.
3. Click the info icon next to Battery Health.
   
   
4. Toggle on Optimised Battery Charging.
5. Press Done to exit the interface.
   
   

Once set up, this feature will learn your charging patterns and adapt accordingly. It will prevent the battery from constantly undergoing a high charging state. 

Note: You may experience slight delays in charging your MacBook to 100% during active usage periods.

10. Consider battery replacement

Finally, if none of the above-discussed solutions have helped you so far, it’s safe to assume that your MacBook battery needs experts’ assistance.  

Over time, lithium-ion batteries can degrade and lose their ability to hold a charge effectively. Hence, you should pay a visit to the nearest Apple store or make a Genius Bar appointment.

They possess the expertise required to diagnose the problem accurately and determine whether a battery replacement is necessary. If so, they will offer genuine replacement options that adhere to Apple’s quality standards, ensuring compatibility and optimal performance.

Overall, this professional approach will thoroughly address your MacBook’s battery issues, resulting in longer-lasting power without compromising safety or performance.
