Q: MacBook Air battery capacity problem
Hi!
I have recently discovered that my MacBook Air battery performance is significantly worse than it used to be. I know that batteries are not permanent, but I am using my MBA since November 2015, so it is not an old equipment yet. Its battery cycle count is 239 and as far as I know the battery should keep a good form for at least 1000 cycles. Current maximum charge capacity for the battery is 4680mAh, which is around 10% lower than the design capacity, which should be 5100mAh. Ten percent for a computer that should be usable for about 8-9 hours straight means that I have lost almost an hour of usability during the workday. I am worried how will it look in a year or so. And I am not even mentioning the situation after reaching the 1000 cycles. So is my battery defective or damaged in some way? Should I contact technical support? I still have the warranty which is valid till mid November. I did not use it very intensive and never stored, charged or used it in a high or very low temperature.
tl;dr
After 10 months of usage and 239 battery cycles my MBA lost 10% of its power capacity. What can I do about it, should Apple warranty cover it?
