Just did a few Measurements with the actual Firmware:
Current was measured in between Battery and the Cubecell Board without USB Power.

  1. LCD on, GPS: on: 50-63mA
  2. LCD on, GPS off: 17.9mA
  3. LCD and GPS off: 11.27mA
  4. LCD, GPS and Radio off, CPU Sleepmode : 11.17 mA

As there is no On/Off switch on the Device itself, we have to fully rely on the Sleepmode for Standby use.
The advertised 21uA from the Datasheet is not nearly reached, so the Battery gets drained fast.

Found the missing piece.. with d469cac the sleep current is now down to 448uA.
Not exactly as advertised, but going in the right direction ;)
