I have used a deep sleep mode as well as some hardware modifications to bring the power usage (in power-down interrupt sleep) to 60.000 times less than the normal (non power save) usage.


Going from:
Code: [Select]
12.000,0 uAh to about
     0,2 uAh in POWER DOWN INTERRUPT MODE and
     4,4 uAh in SLEEP MODE

I achieve the low power by:
  • Desoldering the VReg
  • Desoldering the power LED resistor
  • Desoldering the USB Driver
  • Using a USB FTDI programmer to program the Chip
  • Disabling the watchdog, the ADC and setting all input pin's to INPUT (except the interrupt pin)

Cool! I'm glad my post is useful either for comparison or as a guide to your projects.
