Sorry for the late reply.... At the moment I've got the KickStarter board down to 4mA when idle (as it can sleep) - when executing code I think it's around 40m

Sorry for the late reply.... At the moment I've got the KickStarter board down to 4mA when idle (as it can sleep) - when executing code I think it's around 40mA. Hopefully by release time I'll have sorted out a few glitches and got it down to under 1mA idle (in the range zokier noted). Note that with something like 'setInterval(doStuff, 1000)' the processor will be idle for 99% of the time. Running off a li-ion battery from an old Nokia phone (700mAh) you could then expect Espruino to run for almost a month. Using the battery out of my Galaxy S3 (2100mAh) it'd run for almost 3 months.
