comment out lines 32 and 37. Repeat measurements.

I have also the same problem.
A "out of the box" mini wireless with RFM69 running the above code, cannot get down to 230uA .
I've been checking the presence of the 10K pullup resistor, but the slot is empty on my board.
any ideas ?

Well finally, playing with all pins status INPUT, OUTPUT, INPUT_PULLUP, I ended to get my board 33uA with the same code.
Maybe some of the pullup resistor was locked on. Not sure if it's possible but my problem is solved.

I bought two Mini-WirelessW-915Mhz.
The first one cannot get under 0.45mA
But the exact same code on my second board gets down to 0.03mA (27.2uA)
I'm using emmaanuel's test program (see previous posts).
Both boards have the pullup resistor mentioned by empeka.

I check the pin's mode and states. They are the same on both board except of digital pin #3.
The board sleeping at 0.02mA the pin is a INPUT and HIGH and the board with bad sleep power it's INPUT and LOW.
Looking at the schematic, the RTC is connected to pin 3...

I remember running the RTC&Memory test program on the first board : http://www.anarduino.com/docs/mem_rtc_test.ino
Could it be that it changed something in the RTC that would affect the power usage ?
Or I'm looking in the wrong place ?

Playing around with pin3 (INPUT/OUTPUT/LOW/HIGH) I was able to get down to 0.11mA but I was more out of luck/random, I didn't find exact steps to reproduce/fix it.
Any suggestions ?

The code i used to read my pins:

and the pin's of my GOOD board:

I have the same issue.
