my Macbook battery not as long lasting as it supposed to be
hi all
bought my Macbook air 3 months ago, the battery is disapointing, it is not what it said 7 hours and recently the battery flat out fasted than before, from 100% to 10% just under 3 hours, i was even watching Movie, playing music or youtube. simply just browsing on the net.
MacBook Air, iOS 6
