Battery issues with brand new EOS 5D Mk IV

Hi,

I used my EOS 5D Mk IV for the very first time, went through the menu for approx. 2 hours (monitor illumination at lowest level), made some 20 exposures, and found that the battery dropped from 100% to 16%. After being switched off completely for 12 hours, the battery was down at 11%. I am aware that a battery has ists full performance after several charging cycles. This issue did not occueviously used EOS 5D Mk II, so for me it seems there is something wrong (leakage current?).

Does anyone have an idea? - Thank you.
