*There is no set “mile” or wear from a charge cycle in general OR in specific. *A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.ĭoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles” Never drain them LOW & dont always/often store them HIGH General rule to remember of Lithium batteries is:
Battery life on macbook pro retna portable#
"Apple does not recommend leaving your portable plugged in all the time." When not being used for several hours, turn it off.Īnd best "tip" is if its near a ug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)", however again, not plugged in all or most of the time. Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. Currently in some cases Mavericks is not reporting battery life as accurate in "time remaining" its being looked into.
