Title: Battery life vs. decoding speed
Post by: lee321987 on April 18, 2008, 11:16:46 PM

   I was looking at this page http://www.rockbox.org/twiki/bin/view/Main/CodecPerformanceComparison
and I was wondering...

   If I usually listen to a format that my player (flash not a HD) decodes at 200% realtime, would I double may battery life if I switched to a format that decodes at 400% realtime?  If not double, any significant increase?

Generally speaking, yes, the faster a format decodes, the better battery life it will get. Especially in flash players. In disk players, larger file sizes can offset some of the gain because the disk needs to be spun more. It won't double though, as the CPU is not the only thing draining power, nor is the codec the only code being run on the CPU.
