I’ve been torture testing two clips, fully charging them and then playing an album repeatedly and measuring how long the battery lasts. My Ogg bitrate tests are significantly shorter than the mp3 VBR tests, as much as half the battery life for Ogg Q8.5 vs mp3 V0.
Can someone replicate the test with the Fuze. I suspect the results will be similar. My guess is the Ogg decoder runs the Arm processor at a higher clock frequency.
Could you ask or find out if there is any reason, why my Rev 1 clip gets an hour longer play time vs… The Rev 2 clip, while playing back FLAC files? All The other tests The Rev 2 clip is getting better battery life. Is it possible in The rev 1 code vs. rev 2 code that FLAC is clocked at a different rate? Could it be something intentional? Or an inconstancy in the software? Or are my results just showing something weird and unexplainable? (I’ve tested them twice with simular results).
Just curious and thought I would bring that up, incase its something that might be changeable to make The rev 2 get The same battery life as The rev 1 (for FLAC files).
Yes I read that and appreciate your response. The reason I asked was, I am wondering if the firmware versions have a difference in clocking speed for decoding FLAC. The only reason I wonder about this is, the one clip consistently out performs the other, except FLAC playback. My first guess would be the two are clocking differently on this file type, this maybe incorrect assumption, but I figured I’d ask you to check it out and see.
It’s just a heads up. If there is nothing different, then its just something strange
I wondered why my battery didn’t last long…I think I have the answer now…
I had converted my flac files to ogg vorbis for my fuze because of the said superiority of this lossy codec over mp3 but now i think I’m just gonna reconvert everything to mp3 v0.
Is there any chance that the batterry life using vorbis could be enhanced in a future firmware update?
I’m going to bench mp3 v2 ~ 190k VBR and see what i get for battery life. v0 is great, but I think for my own listening v2 will be good enough. Save some space and still have long battery life and decent quality. Does anyone know what people perceive mp3 v0 and v2 quality wise for the corresponding ogg bitrate / q level?. Maybe a decent review on the net. I guess i can goggle that tomarrow. I don’t want to lose about 33 to 40 % of my playing time/battery. Will post my results and add final comments tomarrow.
