can anybody explain how this is possible, the battery was replaced on 2020-08-05
i have a MBP from 2015 which is in a much better condition
Well its quite simple you got a bad battery ;-{ It appears the source of the chemicals that are used to make the battery where tainted with something so in about a years time the battery degraded. Late 2019 a few battery makers have encountered issues as they used the same source. At this point I would contact the seller of the battery to get a replacement if you can, otherwise it’s time for another battery.
