Does your portable heat up more when you run FLAC?

A high resolution music lover wrote in and mentioned that his portable device got hot and battery died faster when he played FLAC files over the same sampling rate WAV file.  Does this happen to you?  Have you compared your battery drain with a similar DSD file?

We haven't done the test since we're mostly about DSD recording and playback.  But, if you're inclined to test, send us your comments and thoughts.

Enjoy your music!
