Solving the Mystery of Quickly Draining Battery after Upgrading to macOS Sonoma

Are you experiencing the frustrating issue of your Mac's battery draining too quickly after upgrading to macOS Sonoma? You're not alone. This is a common problem that many users face, and in this article, we'll explore some possible solutions to help you get back to normal battery life.

First, let's try to troubleshoot the issue by identifying if it's related to an app or process causing problems. To do this, restart your Mac in Safe Mode. This mode runs macOS in a bare-bones way that prevents certain apps and processes from loading. If your Mac is compatible with macOS Sonoma, you can enter Safe Mode as follows:

For Apple silicon-based Macs, press and hold the power button until you see the login window. Select your main Mac volume from the subsequent list and click Continue in Safe Mode.

For Intel-based Macs, restart your Mac and immediately hold the Shift key until you see the login window. Select your main Mac volume from the subsequent list and click Continue in Safe Mode.

Once you're in Safe Mode, try installing macOS Sonoma again. If it installs successfully, then the problem might be related to an app or process causing issues. However, if you still experience battery drain after reinstalling, there could be another cause at play.

Another possible cause of battery drain is the indexing process that occurs when updating your Mac's operating system. This process can take up extra resources and may take a week or longer to complete. Luckily, this is often not a long-term issue, and it may even clear itself up without you needing to do anything.

If none of these solutions work for you, there are a few more things you can try to troubleshoot the issue. First, make sure your Mac is connected to the internet, as you won't be able to download the macOS Sonoma installer without an active connection. You'll also need at least 25GB of free space on your Mac once the installation is complete.

Finally, if you're still having trouble downloading the macOS update, check Apple's website for a list of compatible Macs and ensure that yours is on the list. If it didn't make the cut, you won't be able to download macOS Sonoma.

By following these steps and troubleshooting your battery drain issues, you should be able to get back to enjoying your upgraded MacBook Pro M3 without worrying about quickly draining batteries.
