Why is the MacBook Battery Draining So Fast After the macOS Sonoma Update?

If your macOS Sonoma is making the battery drain faster, then it can be due to the following reasons-

  • The newer macOS Sonoma version can have some bugs that may cause the battery of your Mac to drain faster. 
  • The issue can be encountered if the apps installed on your Mac are outdated and incompatible with the latest released software update. 
  • Excessive battery drain can also be a result of multiple background processes. These background processes require CPU and memory resources, thus draining your battery life faster. 
  • Another common reason behind the issue is poor battery health. If your Mac is old and its battery life is below average, then that can cause your Mac’s battery to drain faster. 

These were some of the known and common reasons behind macOS Sonoma battery draining faster, but sometimes the issue can be encountered due to increased screen brightness, startup items running in the background, Bluetooth and Wi-Fi, unwanted accessories, etc.

If the battery health is normal, you need not get your Mac serviced. But if you are facing battery drain issues, you can continue with the next step in this article. 

However, if the battery health is shown as Service Recommended, your battery is not in good condition, and you need to replace it. If you see Service Recommended, you will have to get your Mac’s battery replaced, and there’s no point following the other steps until you get your battery replaced. 

Get your Mac to the service center and replace your Mac’s battery, and this should fix the issue. Replacing the battery will fix battery draining issues if poor battery health causes it in the first place.

  • Head to the CPU tab. 


  • Look for the process consuming most of the CPU; select it, and click the x button.

  • Similarly, close all the unwanted CPU-intensive processes. 

6. Disable Startup Items

The battery on macOS Sonoma may drain faster if you have multiple startup apps. These apps start when you boot your Mac and may drain your battery faster. You can try disabling the startup items by following the steps given below-

  • Open the System Settings on your Mac.

7. Ensure Spotlight is Not Indexing

When you boot your Mac the first time after the software update, the Spotlight Search will get reindexed. This may take some time initially, and while this happens, you may see your battery draining faster than usual. You can check whether your Spotlight is indexing by searching for something in the Spotlight. 

Hit up the Spotlight Search by pressing Command + Spacebar. Now, try searching for a file or an app and see if it takes time. If the Spotlight Search takes some time to search for the file or the app, then that means Spotlight is reindexing. 

This might take some time, so you may face battery drain issues while this happens, but it should be solved with the next boot. However, if the search results appear instantly, something else is causing the issue. You can move to the next step in this article to solve it. 

8. Reduce Screen Brightness

High Screen brightness can also cause this issue on your Mac after the Sonoma update. You should turn down the screen brightness and check whether the issue is resolved. 

You can use the F1 key on your keyboard to turn down the brightness and the F2 key to increase the brightness. Check if you still encounter the issue after reducing the brightness or not. 

9. Disconnect Accessories

Have accessories like a USB drive, monitor, keyboard, etc., connected to your Mac? If you have some external peripherals connected to your Mac that you are not using currently, you can disconnect them. 

External accessories that you connect to your Mac take up power from your Mac and make the battery drain fast. If these accessories are not used, you can disconnect and reconnect them whenever required. 

10. Run Apple Diagnostics

If you have tried everything mentioned in the article above, you must run Apple Diagnostics to test your Mac and know what’s causing the issue. Here’s how you can do it-

  • Disconnect all the accessories from the Mac and disconnect it from the power source. Before continuing, you must ensure your Mac is fully charged. 
  • Now, click on the Apple icon at the top and then on Shut Down to turn off your Mac. 
  • Now, the steps vary for Mac with Apple Silicon and Intel-based processors. 
  • For Mac with Apple Silicon-
    • Press and hold the Power button. If your Mac has Touch ID, you must press and hold it. 
    • You will now see the Startup Options. As soon as you see it, release the Power button. 
    • Now, press and hold the Command + D keys together. 
  • For Mac with Intel processors-
    • Press the Power button to turn on your Mac. 
    • Press and hold down the D key on your keyboard as soon as you press the Power button. 
    • You will see a progress bar on your screen. When you see it, you can release the D key. 

Note- If holding the D key doesn’t work, press and hold the Options D keys together.

  • You will be asked to select the language to continue.
  • Once done, you can follow the on-screen instructions to test your Mac. 

If it reports some issue on your Mac, you will have to get it serviced/repaired. 

Bottom Line

We suggest taking your Mac to the nearest Apple service center if the above steps don’t solve the issue or if Apple Diagnostics reports some issues. If there are hardware issues (like issues with the battery), the service center will fix them. If the issue is with the macOS Sonoma update itself, they will downgrade the macOS to a compatible version. 

That’s it with this guide; the above steps should help you solve the macOS Sonoma battery draining fast issue. If you find this article helpful, or if some other method helped you solve this issue and is not mentioned in the above steps, then tell us in the comments section below.
