macbook pro battery
I got a refurbished MacBook Pro 2015 from UAE and when I started using it I noticed that battery health decreased to 80% after 2 cycles now after 10 cycles battery health decreased to 35%
and now I am using it in the charger and it doesn't exceed 45 percent
I can't return it because I am from another country and it will take so much time so if the problem is the battery I will have to change it
so what do you think is this a bad battery replacement or something else??
also, the speakers start crackling but isn't a problem for me because I am using AirPods all the time
