Have you recently updated your Mac to macOS Big Sur and noticed that your battery life has taken a hit? It can be frustrating to experience rapid battery drain for no apparent reason, but don’t worry, there are steps you can take to fix this issue. In this article, we will explore some troubleshooting techniques to help you resolve the battery drain problem on your Mac running macOS Big Sur.
The first thing you should try is simply rebooting your Mac. Sometimes, a simple restart can do wonders and fix any temporary glitches that may be causing the battery drain. Give it a try and see if it makes a difference.
Next, make sure that both your Mac and your apps are up to date. Apple frequently releases updates to macOS that address various issues, including battery drain problems. To check for updates, go to the Apple menu and select “System Preferences.” From there, click on “Software Update” and follow the prompts to install any available updates. It’s also a good idea to update your apps, as outdated software can sometimes contribute to battery drain issues. Visit the App Store and click on the “Updates” tab to see if there are any available updates for your installed apps.
Another useful feature introduced in macOS Big Sur is the Battery Usage History. This tool allows you to see which apps and processes are consuming the most battery power on your Mac. To access it, go to the Apple menu, select “System Preferences,” and click on “Battery.” From there, click on “Battery” again in the sidebar and then click on “Battery Usage History.” Take a look at the apps and processes listed and see if there are any that are using excessive power. If so, consider quitting or disabling them when not in use to conserve battery life.
If none of the above steps have resolved the battery drain issue, it may be worth resetting your Mac’s PRAM (Parameter Random Access Memory) and NVRAM (Non-Volatile Random Access Memory). These are small amounts of memory that store settings related to display resolution, sound volume, and other system configurations. To reset them, shut down your Mac, then turn it back on and immediately press and hold the Option, Command, P, and R keys simultaneously. Keep holding the keys until you hear the startup sound for the second time, then release them. Your Mac will restart, and the PRAM and NVRAM will be reset.
If resetting the PRAM and NVRAM did not help, you might want to try resetting the SMC (System Management Controller). The SMC manages various hardware functions on your Mac, including power management. To reset the SMC, shut down your Mac, then press and hold the Shift, Control, and Option keys on the left side of the keyboard, along with the power button, for 10 seconds. Release all the keys, then press the power button again to turn on your Mac.
It’s important to note that after updating to Big Sur, your Mac may need some time to re-index the Spotlight database and other file databases, including Photos’ library. This indexing process can be resource-intensive and may temporarily cause increased battery drain. Give your Mac some time to complete this process, and you should see the battery life improve.
In addition to the troubleshooting steps mentioned above, there are a few general tips you can follow to enhance battery life on your Mac. Firstly, quit any apps that you are not actively using, as even background processes can consume energy. Additionally, disconnect any accessories that you are not using, such as external hard drives, as they can also drain your battery. keeping your software up to date is crucial, as updates often include bug fixes and optimizations that can improve battery efficiency.
Experiencing battery drain after updating to macOS Big Sur is a common issue, but it can be resolved by following the steps outlined in this article. Try rebooting your Mac, updating your software, using the Battery Usage History tool, and resetting the PRAM, NVRAM, and SMC if necessary. Remember to give your Mac some time to complete the indexing process after the update. By following these troubleshooting techniques and implementing some general battery-saving tips, you should be able to improve the battery life on your Mac running macOS Big Sur.

Why Does Big Sur Drain Battery?
After updating your Mac to Big Sur, you may notice a quicker battery drain compared to before the update. There are several reasons why this happens:
1. Indexing: Following the update, your Mac needs to re-index the Spotlight database and other file databases. This process can be resource-intensive and requires significant CPU usage, which can result in increased power consumption and a faster battery drain.
2. Background processes: Big Sur brings new features and improvements, which may involve additional background processes running on your Mac. These processes can consume more power, leading to a decreased battery life.
3. Compatibility issues: Not all apps and software may be fully optimized for Big Sur initially. Some older or poorly optimized apps may not work efficiently with the new operating system, resulting in higher power consumption and a faster battery drain.
4. Enhanced graphics and animations: Big Sur brings a refreshed design with enhanced graphics and animations. While these visual improvements are aesthetically pleasing, they can require more GPU power, leading to increased battery usage.
5. Wi-Fi and network connectivity: After the update, your Mac may need to re-establish Wi-Fi and network connections, which can consume additional power as the device works to reconnect to networks.
6. Battery calibration: Sometimes, after a major software update like Big Sur, it is recommended to calibrate the battery on your Mac. Battery calibration helps the system accurately measure the battery charge and can help improve overall battery performance.
To mitigate the battery drain issue after updating to Big Sur, you can try the following:
– Give your Mac some time: Allow your Mac to complete the re-indexing and background processes after the update. Once these processes are complete, the battery usage may stabilize.
– Update apps and software: Make sure all your apps and software are up to date. Developers often release updates to address compatibility issues and optimize their software for the latest operating system.
– Adjust energy settings: Review your Mac’s energy settings and optimize them for better battery performance. Reduce screen brightness, enable energy-saving features, and adjust other settings as needed.
– Reset SMC: In some cases, resetting the System Management Controller (SMC) on your Mac can help resolve battery-related issues. Instructions for resetting the SMC can be found on Apple’s support website.
Remember that battery drain issues after a software update are typically temporary and should improve over time as your system adjusts. However, if the problem persists or becomes significantly worse, it may be worth contacting Apple Support for further assistance.
