Power consumption when playing differents music formats

<< < (2/2)

saratoga:
If the numbers you posted above are just estimates then they don't really mean anything. You need to completely discharge the battery to know how long it will last.

ursamajor:
I understand. So, the Rockbox cannot estimate more or less the remaining time of the battery?
I'll post here the running time. I hope my assumption is correct and the battery life will improve after some cycles of recharge.

1)
If you search low demand lossy codec with best quality - MusePack. Not usable without doing a transcode.
The best lossless codec with low demand - FLAC. Avoid using hi-rez formats because they make no sense for increasing a quality of music and not supported by hardware of player. They can be played, but they will be converted on the fly to supported format with worst method resulting a poor audio quality and more power consumption.

2)
Decode Test
The rule is simple. Less MHz needed to decode the file at 1.0x real time, less power consumption.

ursamajor:
Indeed, I know about musepack. It's my favourite format. Still I have musepack music from years ago. For me it sounds better. On the other hand, I didn't know that it's so low power consumption. Thank you. For portable use probably I'll reencode my flac's in musepack.
