For battery life (on the Karma) you are best compressing to Normal, not to mention it is many times faster at compressing.
I feel inclined to question that statement, if these independent test results by
Speek and
Hans Heijden clearly indicate that there is hardly any, if not to say no correlation whatsoever between decoding time and compression level in FLAC. From which one might infer that compression won't have any significant influence on power consumption either.
Encoding time is indeed extended when compressing @ -7 or -8, but since we're talking about a portable device, implying limited storage space and file transfer over USB, compression level, in my view,
is an issue here. I've never considered
encoding speed to be a factor of overriding importance, since encoding is usually only done once. It's the fluent
decoding, playing and searching that matters, as far as I'm concerned. Which is why I value FLAC so much.
