how to reduce consumption

Hello,
Has anyone ever used deep sleep on this component?
Currently I consume 75mA.
When I activate the mode "SLEEP_MODE_PWR_DOWN" the component goes into standby but I go from 75 to 69mA.
The economy seems very weak.
Does anyone already think about the problem?

when I use WiFi.lowPowerMode (); I can save 30mA. it's better but the consumption is still too important for an automome system. I can not know what consumes so much more ..
