I have just been doing a little experimentation with the Battery Test
plug-in on my FMR looking for the answer to two questions.
1) Just what is the battery life of this box - continuous play - The WPS
value for a fully charged box indicates about 12 hours
2) Does enabling the optimised ATA code make any difference?
The results were a little surprising.
With the normal C ATA code - 9 hours 31 minutes
With the optimised ATA code - 9 hours 23 minutes
Both sets of figures give a very good approximation to a straight line when
plotted, so that's good, but
A) The battery life is well short of the estimate - with just about the
lowest power usage scenario you could imagine and
B) The Assembler code seemed to make no difference - in fact showed a small
