​1 :

i only use the Lis3dh ,and remove all other elements

2: i use the power 3.0V, i use multimeter test the current consume between VCC and GND

get the test result current is 16 μA,

(the spec says ,the device automatically enters power-down mode, and current is 0.5μA)​

3, then i add the R1,it used for wake up the MCU,and connect to Lis3dh int 1 port ,

then a test the current like before ,but get the current is 56​μA, it is beyond my imagination .

so i want to ask ,is there anything wrong ?why i cannot get the power down mode current consume like spec says ?
