A discharge rate of 229 mW is not likely.
The other problem though is that upower is all over the map, it varies
between 1 hour and 5 hours remaining. So I wonder if they're both
getting spurious data from the battery or from the kernel (not sure
how it works) and are just handling bad data differently?
Thanks,
