How to Fix Slightly lower battery runtimes in Big Sur?
This mini-guide provides a structural approach to troubleshoot and fix the issue.
Prerequisites
- Confirm your hardware specifications (CPU, GPU, Motherboard).
- Ensure you have a bootable recovery USB and backup your EFI.
Fix Steps
- Check your ACPI patches (SSDTs) for battery and trackpad (e.g., VoodooI2C, SMCBatteryManager).
- Ensure you have applied the correct IRQ patches if audio or trackpad is missing.
- Perform an NVRAM reset after modifying SMC-related kexts.
Verification
- Reboot and verify if the functionality is restored and stable under typical usage.
Original Question:
so I made the jump to Big Sur again this time on my XPS 15 7590, but ive noticed in Big Sur the battery lasts 10 hours 21 minutes whereas Catalina lasted 11 hours, not that the drop is bad but has anyone noticed the same?
