Fix Rapid Battery Drain on Mac After macOS Tahoe Public Beta Update
Regardless of whether the frustrating battery consumption is caused by a corrupted service or an outdated app, or a misconfigured setting, these tips will help you resolve the issue.
1. Disable Unnecessary Background Apps
Do you know that background apps may continue running even when you’re not using them, draining battery power? That’s the reason why it would be better to entirely disable all the irrelevant background apps and services.
- On your Mac, bring up the Spotlight search (CMD+Spacebar) > search for Activity Monitor and launch it.
- Now, sort by “Energy Impact” to identify high-usage apps.

- Then, quit or uninstall apps that are less important. Minimizing background activity helps preserve battery life.
2. Reduce Display Brightness
Your display is one of the biggest power consumers on your Mac.
- On your Mac, head over to System Settings > Displays and reduce brightness manually.
- Now, turn on “Automatically adjust brightness” to optimize brightness based on lighting conditions. Note that lowering brightness can lead to significant battery savings during long usage sessions.
3. Restart Your Mac Regularly
No solution as yet? If the battery drain on your Mac still persists, I’d suggest you reboot your Mac. A fresh restart of your Mac can clear temporary bugs and misbehaving background processes.
- Restart your Mac by going to the System Settings app > Restart.

- This can stop errant apps or services from consuming excess battery unnoticed.
Regular reboots help ensure better resource management during beta testing.
4. Turn Off Unused Connectivity Features
Keep in mind that leaving Wi-Fi, Bluetooth, and AirDrop on when unused can lead to passive battery drain.
- Disable them from Control Center or System Settings when they’re not needed.
- You can also turn off Location Services to further save power.
Disabling unused radios reduces background activity and conserves energy.
5. Manage Login Items and Launch Agents
It’s advisable to keep an eye on the apps that launch at startup and run in the background, increasing power consumption.
- Open the System Settings app on your Mac > General > Login Items & Extensions.

- After that, make sure to remove unnecessary apps from the list. Limiting login items ensures your Mac runs only essential apps during startup.
6. Check for App and System Updates
Be warned that the outdated software or bugs in the beta, or corrupted apps can cause power inefficiency.
- Open the App Store on your macOS device > Updates tab located in the left sidebar and update all installed apps.

- Next up, dive into the System Settings > General > Software Update and install the latest beta release.

- Apple often addresses such issues in subsequent beta patches, so stay updated.
7. Enable Battery Optimization Settings
Last but not least, make sure to fine-tune the battery optimization settings. Bother not! macOS has built-in options to let you manage power more efficiently.
- Navigate to System Settings > Battery.

- Turn on “Optimized battery charging” and enable “Low Power Mode” when needed.
These features reduce background activity and manage energy consumption smartly.
Wrapping up..!
And that’s about it! macOS Tahoe Public Beta brings exciting features, but battery drain can be a frustrating side effect. By managing background apps, tweaking power settings, and staying updated, you can significantly improve your Mac’s battery life. Try these fixes to make the most of the new update without sacrificing performance.
