Take a look at the very first post "Li-Ion self-discharges about 5% in the first 24 hours and then loses 1-2 percent per month". IF that is the case I assume that every time you or "genius" turn your machine back on and then shut down you could lose 5% in the first 24 hrs all over again...maybe.... What if you shut it down let's say for 3 days - are you gonna lose 15%-18% or is it going to be more like 6%-8% over 72 hrs (5%-6% in first 24 hrs and then very minimal discharge over the next 48 hrs +/- power needed to power back on and +/- for battery meter accuracy). Try shutting it down for at least 3 days and let us know.The Genius guy allready disable this feature (as he said) and didn't note any changes.
When I took back my machine, i check the log and I saw that the computer was really turned on by somebody every day.
The starting charge was under 90%, and every day, the battery loose 5-6%.
The Genius guy saw this log and, even if he was aggreed with my surprise, he concludes that my computer had no issue...

According to the poll above as of 08/29/2017 over 30% of MBP users indicate that they have no discharge at all and that's alarming for us who have machines that self discharge consistently :-(Hi,
My MacBook Pro 2016 with Touch Bar is self discharging 6% per 24 hours when completely off (shutdown).
I never had this issue with my different old MacBook.
After several tests, Genius Bar expert tells me that the behaviour is nomal, and certainly due to new hardware generation (perhaps a component not completely off after a shutdown).
The guy gaves me back my computer saying if I want to change a hardware component, like my battery (20 charging cycles...), I have to pay because my Mac has no issue...
No issue... How a machine can stay "up to 30 days in standby time" if it losts, in real life, 6% per day when switched off and much more in standby mode?
I also have a Surface Pro with "new hardware generation" and I haven't any battery discharging problem when switched off...
