Apple’s current crop of MacBooks based on the company’s own M1 and M2 processors have better battery life than the previous Intel-based machines, but there are still some easy ways to extend your MacBook’s running time. If you’d like to improve the battery life, we’re here to say you don’t have to trail a bulky charger just to get through the day (although ancient laptop batteries may legitimately need to be replaced).

For most people, you can take a few minutes to adjust some settings to extend your laptop’s battery. Below, we’ll show you how to check its health, as well as cover tips like reducing keyboard and display brightness. We also make the case for using the Safari browser over Chrome.

Check your MacBook’s battery percentage

Keeping an eye on the remaining battery life won’t make it last any longer, but it can help you plot out how much work you can get done before you need to recharge. Click on the battery icon in the menu bar to see how the percentage of battery remaining. And if you’re running on AC power, it will give you an estimate for how long you need to continue charging the battery to bring it back 100% charged.

Here you can also see which apps, if any, are causing significant battery drain.

Check your MacBook’s battery health

Whether you buy a refurbished MacBook or you’ve been trying to squeeze every last ounce of life out of your aging MacBook, it’s a good idea to check your battery’s overall health. MacOS includes a tool that will tell you its potential capacity, and if you need to have it replaced.

To view your battery’s health report, click the battery icon in the menu bar, then select Battery Preferences. Next, make sure the Battery tab on the left side of the window is selected then click Battery Health. A window will pop up showing you the current condition as well as the max capacity. If you have questions or want to know more about what the status means, click the Learn More button to open an Apple support page that’s specific to your MacBook’s processor (Intel or Apple Silicon).

For those who want more insight into their MacBook’s battery history, you can view the number of charge cycles the battery has gone through. Click on the Apple icon in the upper-left corner, and then while holding in the Option key on your keyboard, click System Information. The System Information app will open, where you then need to find and select the Power section, and then look for Health Information. There you’ll see your battery’s health, capacity level and cycle count. For reference, check out Apple’s chart of the expected battery cycles. Most newer MacBook batteries have an expected life of 1,000 charge cycles, after which Apple suggests getting your battery replaced.

Optimize battery charging

If your MacBook is going to spend most of its time plugged in, you’ll definitely want to change this setting. MacOS can learn your charging habits to reduce battery aging. Click on the battery icon on the menu bar at the top of your display and select Battery Preferences from the drop-down menu as mentioned earlier. At the bottom of the list of options, select Optimized battery charging. This will slow down your charging once the battery hits 80%.

Save battery by dimming your display, optimize video streaming

Powering the display is the biggest drain on battery resources. So, first things first: Lower the brightness of your display to a level that’s comfortable for your eyes. The brighter your display, the shorter your battery life. You can also set the display to dim slightly on battery power and to shut off after a period of inactivity by going back to Battery Preferences.

There’s an option to slightly dim the screen when you’re on battery power, and to reduce battery drain when streaming video on battery power. I also suggest customizing how long your display will remain on to as short of an amount of time as you can. That way when your attention is elsewhere, your MacBook’s screen turns off completely, saving precious battery life.

Kill keyboard backlights when not needed

A backlit keyboard is great for typing in the dark, but it can also drain your battery. You can set the keyboard backlights to turn off after a period of inactivity so that they’re on when you need them and off when you step away. Go to System Preferences > Keyboard. On the Keyboard tab, check the box for Turn keyboard backlight off after [X secs/min] of inactivity. Your options range from 5 seconds to 5 minutes.

I also suggest checking the box next to Adjust keyboard brightness in low light to ensure your custom brightness controls are preserved, regardless of how dim or bright the area you’re working in is.

Turn off Bluetooth if you’re not using it

There is a good chance you won’t be carrying around a Bluetooth mouse or speaker when you leave your desk. With nothing to connect to, there is no point in having Bluetooth enabled. I recommend disabling the radio to conserve battery. Just click the Control Center icon in the menu bar, then click Bluetooth and click the switch to slide it to the Off position.

The only potential downside with disabling Bluetooth is that Apple’s Continuity feature, which allows you to quickly and easily share information between your iPhone or iPad and Mac, won’t work.

Consider switching from Chrome

If Chrome your main web browser, you might consider making the switch to Apple’s Safari browser. Chrome is a known resource hog, taking up precious memory, and by extension eating into a laptop’s battery life.

Apple’s battery life estimates for its MacBooks are calculated with Safari as the default web browser. If you’ve never used Safari as means to get around the web, you’ll be surprised at how capable it is. I personally use it as my main browser and rarely run into any issues, which wasn’t the case just a few short years ago.

Keep current with software updates

Staying current with MacOS updates will help you get the best possible battery life. To check to see if an update is available for your MacBook, go to System Preferences > Software Update. While you’re there, check the box to Automatically keep my Mac up to date, and clicking the Advanced button will let you check for updates automatically, download them automatically or install them automatically.

Quit applications you’re no longer using

It’s best to close programs when you are done using them. This can be done by pressing the Command and Q keys at the same time, or click the program name in the menu bar and selecting the Quit option. To see how much energy each of your open applications is using, open the Activity Monitor and click the Energy tab or click the Battery icon in the menu bar.

Disconnect accessories after you’re done with them

As with Bluetooth, if you aren’t actively using a USB-connected device (such as a flash drive), you should unplug it to prevent battery drain. If the power cord isn’t connected, charging your smartphone or tablet via the MacBook’s USB port will also drain your battery.
