  • Current when power is first applied - 82.4 mA
  • Current when switched off: 4.2 mA
  • Current when switched on from the keyboard: 42.4 mA
  • Current when switched off again from the keyboard - 6.8 mA
Subsequent currents are all close to 42mA (on) and between 5mA and 10mA (off).

One extra piece of information that might give a clue: I've left the calculator turned off for about 2 hours and the current settled at about 4 mA. Removing the SD card causes the current to jump up to 10 mA. Re-inserting the card causes the current to drop back to 4 mA again, even before the card is properly seated. Simply having the card mostly in without pushing causes the current to drop.
