The battery I've just got is behaving strangely
a couple of weeks ago I’ve purchased a battery for my Mac from iFixit EU store (Order No. 355170). Installed and checked it, everything seems to work just fine, but after few days I’ve realized a strange behavior.
The battery goes down from 100% to 40-30% as expected then it suddenly jump to 7-6%. But even stranger, the Mac keep working for at least another 30-40 min while the battery keep showing 6%. The bad side of this scenario is that when the battery is at 6% the MacOs detect the “battery low” status therefore the Mac became slow as a sloth.
I’ve reset PRAM and SMC but nothing changed. From the coconutBattery utility battery health seems fine so, I don’t know what to do.
