Hello there. I need advice/suggestions on the current health of my Macbook pro battery. It's an early 2015 model (13-inch Retina) and I got it last 2016. I think there's a problem with the battery because it's already giving me the Service Battery (at 75 percent design capacity) notification but cycle count is still at 378. Anyone who can help/give their two cents? I don't have Apple care btw.
