use average current vs. momentarily #8

Enhancement:
I'd suggest to use file
/sys/class/power_supply/battery/current_avg
instead of currently used
/sys/class/power_supply/battery/current_now

_avg one do some averaging in the kernel, thus result is more stable.
_now just reads momentarily value, it may have large fluctuations.

Sorry, it is not a good idea - at least, on NexusOne, averaging period is too 
large.

perhaps, do some few second averaging instead?

The problem is that current_now updates every 20-30 seconds or so.
I guess that's the reason for the large period in current_avg.

yes, I run this test too... indeed, fluctuations I saw was a glitch.

just dismiss this issue. _now is more appropriate.

If you'll find anything else I'd be happy to hear. :)
