Does keeping power adapter connected decrease battery life?
I recently bought a Macbook Air and needed some tips to keep it's battery healthy. Now I know that the battery has limited cycles before it goes down to less than 80% charge capacity. But if I keep my adapted connected as much time as possible, to reduce the number of those cycle counts, will it harm it battery? What is best way to keep the battery running healthy for long time - charging it once a day or using it with adapted connected most of the times?
Thanks in adavnce.
