MacBook Pro 2016: battery drain when switched o...

I there,

 

My MacBook Pro (13" late 2016 with Touch Bar, 17 charging cycles) is draining about 6% battery per 24 hours when completely switched off using shutdown (in standby mode with lid closed, the battery drains is about 15% per 24 hours).

 

I had many MacBooks by the past but it's the first time I encounter this behavior.

 

After several tests, the Apple Store Genius said my battery health is OK and then asked Apple engineering. The answer was: normal behaviour with the new hardware generation.

 

Not convinced (I have a Surface Pro with "new hardware" and no battery draining problem when switched off), I asked for a second set of tests in comparative mode (with other machines).

 

Battery drain when switched off has been confirmed with a machine identical to mine (6%) and a MacBook without Touch Bar (4-5%).

 

I am very surprised about the results. How a machine can stay "up to 30 days in standby time" if it lots 6% per day when switched off (and then completely discharged in 17 days), and two or thee times more in standby mode?

 

So my question: do you encounter any identical behaviour with your machines?
