Is it okay to unplug my macbook pro before it is fully charged?

Question

I have heard that it is terrible to unplug a PC before it is fully charged but is it also bad to unplug a mac before it is fully charged?

Why is it bad to drain it to 15% and less?
Its very hard on the Lithium battery.
If your out and there is no power, you can do that a few times, or rarely "sometimes",
.... but dont ever make a habit out of it or do it "often"
Expected Lithium charge cycle "LIFE" based on DEEP DISCHARGE (generally)
not specific to macbook cells but lithium cells in general
there isnt a battery expert on earth that hasnt said repeatedly that "deep discharges on Lithium batteries BAD"
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”
**A person who has, for example, 500 charge cycles on their battery and is recharging at say 70% remaining of a 100% charge is a whole world better and different than another person who has 500 charge cycles at say 20% remaining on a 100% charge.  DoD (depth of discharge) is infinitely more important on the wear and tear on your Macbook battery than any mere charge cycle count.  *There is no set “mile” or wear from a charge cycle in general OR in specific.
As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
LiPo batteries do NOT like to be dropped down to 15% or so often,....key word being "often"
A lot of battery experts call the use of LiPo cells the "80% Rule" ....meaning use 80% of the charge or so,.. then recharge them for longer overall life.
