So I bought my MBP around a month a go and I did calibrate it for around a week or so with the battery health of 95%. When I changed the HDD to my Scorpio Black the battery health started to decrease slowly... I don't know what to do, if I should keep calibrating it or not because right now it's at 88% and I think it keeps going lower. The only thing I really do it hook it up to my external monitor via HDMI sometimes. I don't leave my MBP charged all the time, letting it die out after it's full charged, but all it really did was decrease the battery health. What do I do to increase my battery life, since it's at 88% and 22 cycles right now?
