How to Fix macOS Sonoma Battery Life Problems

If you want to avoid a trip to the Apple Store, try fixing macOS Sonoma battery life problems on your own.

If you recently moved your Mac from macOS Ventura to macOS Sonoma, and your Mac’s battery seems to be draining faster than it should be, there are some steps you should take before contacting with Apple customer service.

Restart Your Mac

If you start to notice abnormal battery drain on your Mac, the first step is a simple restart. Power your Mac down, wait for a minute, and power it back on and see if battery life improves. If it doesn’t, move onto the next steps.

Update Your Mac

Apple will occasionally release new macOS Sonoma software. Point updates (x.x.x) typically patch up bugs and security issues while milestone upgrades (x.x) usually deliver a mix of features and fixes.

Apple may not list fixes for battery drain issues in a macOS Sonoma update’s change log. However, new software always has the potential to help. If you’re running outdated macOS software, consider updating. It could help.

Update Your Apps

Developers are pushing new updates for their applications and a new version of an app could help alleviate macOS Sonoma battery life issues.

Go into the Mac App Store and check for recent updates. If you’re feeling leery, dig into reviews from Mac users currently running macOS Sonoma.

You’ll also want to click on the battery icon in the upper right corner of your Mac. If you see an app “Using Significant Energy” you’ll want to check in with the developer to see if there’s update, an update planned, or if there’s a known issue with macOS Sonoma.

Check Processes

It could be that one, or more, of your applications are hogging your Mac’s resources. This will cause the battery to drain rapidly. You can investigate using the built-in Activity Monitor feature.

In the Finder, find Activity Monitor and open it. You should be on a screen like the one in the screenshot above. Now, click the Energy tab.

Now click the Energy Impact tab. This will sort the list by the apps and processes using up the most energy. If you see an app or process utilizing a ton of energy, highlight it and click the “X” in the toolbar.

Check Your Battery Usage History

Usage History gives you details about your Mac’s battery life over the last 24 hours or the last 10 days. You’ll find it in your Mac’s System Settings, located in the “Battery” section.

It’s broken down into Battery Level and Screen On Usage so you can see how your Mac’s battery is currently performing. If the readouts don’t look right, you might need to get into contact with Apple customer service.

You’ll also notice Battery and Power Adapter sections. You can select when to turn your Mac’s display off, turn power nap on or off, and a whole lot more.

Turn Down Screen Brightness

If you constantly have your Mac’s display set at maximum brightness, that could be the issue. We recommend enabling the “Automatically adjust brightness” feature on your device to help prevent battery drain. This option is only available if you own a Mac with an ambient light sensor.

Here’s how you enable it:

  • Click the Apple logo in the top left corner of the screen
  • Select System Settings
  • Click Displays in the sidebar
  • Toggle Automatically adjust brightness on

You can also manually adjust the brightness of your Mac’s display. One way is to use the F1 and F2 keys on the keyboard. The other way is to use Control Center, located in the upper right-hand corner, and adjust the brightness using the slider located there.

Reset PRAM and NVRAM

If nothing above works, you can try resetting your MacBook’s PRAM and NVRAM. This resets some settings, but it doesn’t delete your Mac’s data.

Here’s how to do this. Note that this will only work with Intel-based MacBook models:

  • Use the power button to turn your MacBook off
  • Press the power button to turn your MacBook back on
  • While it’s starting, press and hold the Command + Option + P + R keys together
  • Continue holding the keys until you hear the startup sound twice
  • Release the keys and allow your MacBook to start up normally

Reset SMC

The System Management Controller (SMC) manages hardware functions like your MacBook’s battery. You can try resetting it to see if it helps improve battery life:

  • Use the power button to turn your MacBook off
  • Press and hold the Shift + Control + Option keys and the power button simultaneously for 10 seconds
  • Release all keys and the power button
  • Press the power button to turn your MacBook back on

If you have a MacBook Pro or MacBook Air with Apple silicon, you simply need to restart your device.


If you can’t find a fix for your problem and/or don’t want to wait for the next version of macOS Sonoma, you can try downgrading your Mac’s software back to an older version.

4 Reasons Not to Install macOS Sonoma & 11 Reasons You Should

Install macOS Sonoma for Better Security

Install macOS Sonoma for Better Security

If security is important to you, think about installing Apple’s macOS Sonoma update right away.

The macOS Sonoma update brings a ton of new security patches to Mac devices. And when we say a ton, we mean a ton. 

macOS Sonoma has over 50 security updates on board to help protect you and your device from harm. You can learn more about them over on Apple’s security site.

If you skipped older versions of macOS, like macOS Ventura 13.6, you’ll get the security patches from those updates with your update as well.

In addition to those patches, macOS Sonoma brings additional enhancements to privacy and security including improvements to Communication Safety beyond Messages.

It now includes content sent and received in the systemwide photo picker and third-party apps. You also have an option to blur out sensitive photos and videos before you choose to view them.

There’s also an expanded Lockdown Mode which will help protect you against cyber attacks and improved sharing permissions which means you have more control over what you share with the apps on your device.
