Purple dot on my macbook pro?

Macbook pro battery health?

• I just bought my macbook pro, and i did 4 cycles of battery charging and my health went down to 98% i usually wait until my battery goes to under than 10% then charge to full is this wrong or should i dot something else. I usually use it at home is it ok if i keep it running on ac power most of the time or should i plug it out once its fully charged.

• Answer:

  if your gonna use the battery use it all the way. if your gonna use ac avoid plug and deplug as much as possible it might destroy your bat
