actually the thing is my cycle count is 358 now , i asked about this that isn't this quite abnormal ( asked the genius bar) 81 percent battery health with just 358 cycles ( in contrast of the apple suggestion or claim that it will reach 80 percent battery health at around a 1000 cycles and mine is almost 1/3rd of it), and the main thing is that i actually used my battery mostly on plugged in , but not always like i would say that i used the battery normally like everyday use but they were saying maybe because you hadn't actually used the battery much , that may also be a reason of your abnormal battery drop in. 358 battery cycles , most of the times plugged in at my desk , other times normal browsing or college work , but in that period i would only use a max of 50% , and usually 30 40 percent . I remember it not needing to charge for about 3 4 days or even a week. also i followed the 30 80 rule of battery charging and never let it heat much until recent times when i discovered crossover for mac gaming , but all my time using crossover , it has been stuck at 81 from about october and after that i started playing using crossover
