Your iFixit battery likely has faulty calibration or firmware, causing macOS to misread charge levels—contact iFixit for a replacement or warranty check.

@wolfganggessl Go to your finder and go to your macbook under locations, navigate to the library / preferences / then delete the 3 or 4 files com.apple.power* / empty the trash then reboot and see if that made any difference. These files will be created new upon reboot.

HI I found the location off the files but I got 5 related to Power
com.apple.powerlogd
com.apple.powerlogd.plist.ADTPLF3
com.apple.powerlogd.plist.W67mu8n
com.apple.PowerManagement.CA179EC3-39EC-5B20-8053-C973A39C784B
com.apple.PowerManagement
Just delete all 5 ?
@wolfganggessl I am using a 2015 15" model, I have 3 - com.apple.powerlogd / com.apple.PowerManagement.EADC2779-E9B8-560C-AC0B-B65836358999 & com.apple.PowerManagement. I would think it would be OK to delete all 5 as they should be auto generated upon reboot.
Interesting!!
I deleted all 5 files rebooted and checked in finder again now I got 3 files recreated
I let you know If it worked after one more calibration sickle
Thank you much for the help

MacBook just shut down this time whit 67% left
Im no expert in this this is why I'm asking here but is it possible the % reported is correct and the Ifixit battery replacement's BMS is faulty
would explain thad I don't get a low battery warning ?
