Is it normal to lose 10 - 15% battery power when 13" MacBook Air (purchased new in fall 2013) has been powered off for 7 seven days?  Li-ion batteries are supposed to retain their battery charge when devices are powered off; that 10 - 15 % loss seems like a lot for one week.  On the other hand, my 2013 iPad does not have this problem. Thanks for any info submitted.
