Big Sur Battery Drain While Sleeping

Hi BerkcanBatu,

We understand that you're not getting the battery life you expect from your Mac. If you haven't yet, we recommend reviewing Activity Monitor for battery usage, and processes that may be using a significant amount of power. The following page explains how: View energy consumption in Activity Monitor on Mac

You can find additional guidance to help you get the most from your Mac's battery, here: Tips for MacBook Air and MacBook Pro.

We hope this helps!

Thanks for getting back to us, and keeping us up to speed BerkcanBatu,

Seeing Spotlight showing for so long in the list of apps that use significant power certainly wouldn't be expected. To help isolate the behavior further, we'd like to have you try running through a complete battery cycle, from 100% until it's below 10%, in safe mode.

Safe mode has a couple of functions. First, it's going to run a check on the startup disk as your Mac boots. It also temporarily disables non-essential software from loading at startup. As a result you may see your Mac take a bit longer to boot into this mode, and not all features and functions may be available while in safe mode. However, testing in this mode can help isolate whether the issue is being caused by a conflict or issues with software.

The following page provides some additional information about safe mode, and how to use it: Start up your Mac in safe mode

Post your results after you complete a full battery cycle in that mode, did the battery last longer when in use? Did it last longer when the Mac is sleeping? Does Spotlight still show significant battery usage? We'll continue from there.

Take care for now!

Thanks for testing in safe mode and sharing your results BerkcanBatu,

We see Spotlight is no longer showing in the list of apps using significant battery power, and it is expected for your Mac to use some power as it sleeps. If you haven't already, disabling Power Nap can reduce the amount of power that's used while sleeping. You can find information about the feature, here: What is Power Nap on Mac?

So we can learn a bit more, may we also ask to check the number of battery cycles on your Mac? You can find this with the information provided here: Determine battery cycle count for Mac notebooks

Thanks!
