I remember hearing that too, but we are so far from Taipei we hear less
than 1% of 1% of what goes on.  If Tony explicitly said it was resolved
for production after the fact I'd tend to believe that.

Anyway folks can tell by getting their device idle and

/sys/devices/platform/bq27000-battery.0/power_supply/bat/voltage_now
/sys/devices/platform/bq27000-battery.0/power_supply/bat/current_now

with the LED lit and not lit.
