8 Tips for Improving Battery Life on Your MacBook



Thanks to more efficient processors, the battery life of Apple's MacBooks improves with every new model year. However, the full-time battery life of a new MacBook will slowly fade and you will run into a power outlet more often as you grow older. (Hey, none of us stays young forever.) In System Preferences, you'll find some settings for dimming and shutting down the screen in Sleep mode. However, there are other ways to extend the life of your system MacBook MacBook Air or MacBook Pro .

Battery Percentage Display

Keeping an eye on remaining battery life will not preserve battery life. However, it can be helpful to find out how much work you can do before you have to recharge. If your MacBook only shows the battery icon in the menu bar, I suggest adding the percentage next to it. Just click on the battery icon in the menu bar and click Show Percentage .

Check the battery condition.

Next, you want to check the condition of your battery. To do this, hold down the Option key on the keyboard and click on the battery symbol at the top of the menu bar. You will see one of four conditions:

  • Normal: The battery is working normally.
  • Replace soon: The battery is working normally but is less charged than when new. [19659012] Now replace: The battery is working normally but has a much lower charge than when new. You can continue using the battery until you replace it without damaging your computer.
  • Service Battery: The battery is not working properly, and it may happen that the behavior or amount of charge does not change. Bring your computer to the service. You can continue using the battery before it is tested without damaging your computer.

According to Apple, a MacBook battery can hold up to 80 percent of its original capacity in 1,000 full charge cycles. Hold down the button click the Apple icon in the upper-left corner, and then select System Report . In the left pane, click Power and look for the number of cycle counts under Health Information.

Darken the display

Turning on the display is the biggest drain on battery resources. First things first: Reduce the brightness of your display to a comfortable level for your eyes. The brighter your display, the shorter the battery life. You can also set the display to slightly dimming the battery power and turn it off after a period of inactivity. Go to System Settings> Energy Saver. If you are using battery power in a bright environment, you may want to disable the automatic brightness feature. To do this, go to System Preferences> Display and uncheck the box Automatically adjust brightness .

Staying up-to-date with software updates

Staying up-to-date with MacOS updates gives you the best possible battery life. To check if an update is available for your MacBook, go to System Preferences> Software Update . While you are here you can activate the checkbox . Automatically keep your Mac up-to-date . If you click the Advanced button, you can automatically check for updates, automatically download or install them, or install them automatically.

Disable keyboard lights when they are not needed.

A backlit keyboard is great for typing in the dark, but can also drain the battery. You can set the keypad backlight to turn off after a period of inactivity, turning it on when needed and turning it off when you get off. Go to System Preferences> Keyboard . On the Keyboard tab, select the check box Disable the keyboard illumination after ____ of inactivity . Your options range from 5 seconds to 5 minutes.

Disable Bluetooth.

When you leave your desk, you're unlikely to carry a Bluetooth mouse or speaker with you. If no connection can be made, there is no point in activating Bluetooth. I recommend to disable the radio to save the battery. Simply click on the Bluetooth icon in the menu bar and select Turn off Bluetooth . You can also go to System Preferences> Bluetooth and click the Turn off Bluetooth button .

Quit applications that you no longer use.

It's best to shut down programs when you no longer need them. This can be done by simultaneously clicking the and Q buttons or by clicking on the program in the top menu bar and selecting the Quit option. Open the Activity Monitor and click the Energy tab to see how much energy each of your open applications consumes.

Disconnect unused dongles.

If you are not using a device actively connected to a USB device (such as a flash drive), you should unplug it as you would with Bluetooth to save battery life. If the power cord is unplugged, charging your smartphone or tablet through the MacBook's USB port will also drain the battery.
