Understanding macOS Sequoia Battery Drain
When you notice your MacBook’s battery depleting faster than usual after updating to macOS Sequoia, it’s natural to wonder if the operating system is the culprit. The truth lies somewhere in between. Sequoia’s updated features and higher resource demands may consume more power, especially if your Mac is running older hardware. However, most of these issues stem from how resources are managed rather than a fundamental flaw in the system.
So, while Sequoia might not directly cause battery drain, its energy demands could amplify inefficiencies in your current setup. By making a few adjustments, you can optimize your Mac’s battery usage and enjoy the benefits of macOS Sequoia without compromise.
9 Quick Fixes for macOS Sequoia Battery Drain
1. Free Up RAM
Limited RAM availability forces your Mac to rely on the startup disk for temporary storage, increasing power consumption. To free up RAM:
- Use a tool like CleanMyMac to monitor RAM pressure.
- Open the Menu App from the menu bar and click Free Up Memory.

2. Close Unused Browser Tabs
Browser tabs consume significant resources even when idle. Bookmark unnecessary tabs and close them to reduce memory and CPU usage, directly impacting battery life.
3. Quit Energy-Intensive Processes
Use Activity Monitor to identify processes consuming the most energy:
- Navigate to Applications > Utilities > Activity Monitor.
- Open the Energy tab and sort by Energy Impact.
- Quit unnecessary processes by selecting them and clicking the [x] button.

4. Update macOS to the Latest Version
Software updates often include fixes for bugs that may affect battery life. Ensure you’re running the latest version:
- Go to System Settings > General > Software Update and install available updates.

5. Manage Login Items and Background Extensions
Apps that launch at startup or run in the background can significantly drain your battery. To disable these:
- Use CleanMyMac’s Performance Module to manage login and background items.
- Alternatively, navigate to System Settings > General > Login Items and manually disable unnecessary applications.

6. Optimize Battery Health Settings
Tweak your Mac’s battery settings for improved efficiency:
- Open System Settings > Battery.
- Check Battery Health to ensure it’s in normal condition.
- Adjust settings like Put hard disks to sleep when possible and Optimize video streaming.

How to Fix macOS Sequoia Battery Drain During Sleep
If your Mac’s battery drains significantly while in sleep mode, these fixes can help:
7. Quit Browsers Before Sleep
Third-party browsers may not properly enter sleep mode, consuming resources overnight. Close all browser windows before putting your Mac to sleep.
8. Enable Low Power Mode
Activate Low Power Mode to reduce background processes during sleep:
- Go to System Settings > Battery and select Only on Battery for Low Power Mode.

9. Activate Hibernation Mode
Hibernation mode puts your Mac into a deeper sleep state, minimizing resource usage:
- Open Terminal from Applications > Utilities.
- Enter the command:
sudo pmset -a hibernatemode 25
. - Press Return and close Terminal.

Conclusion: Optimize Your Mac for Maximum Efficiency
Introducing macOS Sequoia is a step forward in innovation, but it does place higher demands on your Mac’s resources, which may result in faster battery depletion. The good news is that these issues are manageable. Following the nine fixes outlined above, you can optimize your Mac’s performance, extend battery life, and enjoy everything macOS Sequoia offers without interruptions.
Remember, keeping your Mac updated and managing resources effectively is key to maintaining a seamless and efficient workflow. Tackle battery drain head-on and ensure your Mac stays powered up for all your daily challenges.
Thanks Ruby. All of the above are actioned, apart from Hibernation mode, which I’m holding off on for the moment. My problem is indeed huge battery drain in use since Sequoia – even with update to 15.2. My biggest annoyance is putting the machine to sleep for a while, or overnight, and coming back to a screen showing no battery charge – I plug in the power source and I instantly have 52%. Do you perhaps have some guidance on that please?
Hello Kev,
Are you on the stable version?
Thanks
