Rockbox small question etc

AlexP:
On that very page, at the bottom is the most recent test (which I did):


--- Quote ---e260
Rockbox:  16:28:47
OF:  14:08:41
Repeat album (MP3 192 kbps 75 MB)
2008-02-11
SVN 16287
Both with settings reset, Rockbox with Cabbie v2 WPS, both with the same album on repeat, and with hold on therefore screen off. Both were measured by plugging the headphone out into the H140 and recording it :) AlexParker

Granted it is 4 months old now, but things should have only got better not worse since then.  You will note Rockbox got significantly better runtime than the OF.  I measured both by recording the output on my H140, and thus the results are accurate.

@ BigBambi ...

i assume the e260 is pretty much the same as the e250 besides the obvious 2GB vs 4GB thing?

if that is it's cool since you where testing 192kbps MP3's and since im using 45kbps .ogg i would assume it's safe to say that i will get even better battery life assuming my battery is in good running order?

cause he was saying in a previous post i should expect to get around 20hours or so at the 45kbps bit rates im using.

just curious as to what your thoughts are ;)

AlexP:
Yep, other than storage they are the same.

On this page are some tests with comparisons of codec performance:

Although the e200 results are a bit out of date, you can see that at that time low bitrate vorbis decoded more efficiently than higher bitrate MP3, so all else being equal, 45 kbps OGG should give longer runtime than 192 kbps MP3.  Of course, as you say, the actual battery life will depend on age etc.

gnu:
... but your EQ presets etc. will draw some addidtional current, thus decreasing your battery life.

Llorean:
That's actually not a 100% guarantee. Though in the case of Vorbis it should be true, if a codec can run unboosted on a player, it may be possible for it to run unboosted with some EQ, in which case there wouldn't be a penalty.
