similar problem with MacBook Pro 15 mid2014. bought from eBay and battery cycle count was only 4 and 9000mAh, now has 40cycle and dropped 800mAh after one month ideal usage. anyone knows what is causing this health drop? run diagnostic everything seems okay, Mac works absolutely fine with no issues, no errors was found but i’m losing battery health every week can’t understand what’s going on.
just discovered that my Mac has battery with model A1494, when MacBook is A1398. can this model difference be reason for health drop?
