Ipod battery. Only 1 hour?

[Sepharat]

Hi. I have installed rockbox in a 60gb ipod and have stored 30gb of ogg music in it. I´m using a theme I think it uses more resources than the first one but i´m not sure if it´s normal that i can use the ipod only for an hour. And when the ipod is full recharged, when i start it, the battery shows that there is a small part of it used, is it normal? Another thing, this normal I think, is that when i´m playing a song, the ipod becomes more slowly. I have read the problem is that the ogg codec is not optimised but i don´t know where i have to read to know news about this part of the project
Thank you and congratulations to the developers for this great work

Only getting one hour of battery life would be VERY unusual  What kind of battery life do you get in the original Apple firmware?  You should get ~50% of that number when using Rockbox.  Are you sure your battery was fully charged?  

Upon startup, my iPod also shows a small part of the battery as used, even when fully charged.  This is normal (for now).

The music playback thread gets CPU priority over the user interface thread.  Compound that with the slow scrolling speed on the iPod video, and you get very sluggish scrolling while playing a song.

I don´t know how much time i can use my ipod with Apple firmware because i installed rockbox to be able to listen my ogg music when i bought it. I will make a test tomorrow to know it. Do you know how much time is the normal battery life in this model of ipod? And do you know if there is any developer who is working in the ogg codec to extend battery life?
Thanks

i'm no coder, but i doubt improving the codec will do any good.
From what i understand, Rockbox currently uses the IPOD's main processor (ARM) to do the decoding (hence the sluggish scrolling while playing) and not the chip apple put in there to decode audio.
The ARM slurps up your battery like crazy.

That is incorrect.

The iPod Video has a special chip (made by Broadcom) to do video decoding, but no hardware audio decoder.

Improving the codec will improve battery life.  When the ARM is idle we can reduce the clock speed which uses less battery, and if we have more optimised codecs then the ARM is idle more.

Wow since you have a 60gb this is very unusual. My 30gb iPod gets about 3-5 hours when playing doom. About 15 when not doing anything and just in rockbox. Yours should be at about 18 hours.

gravedigg, the 60gb ipod will NOT get 18 hours in Rockbox.  It is probably closer to 8.

[Sepharat]

but 8 hours with rockbox or with apple firmware? And if it´s with rockbox, ¿how much with apple one?
Do you know if there is any progress in improve battery life?

Which 60gb iPod do you have, the photo or video?

[Sepharat]

I have video ipod. Do you know which is the capacity of the standard battery that comes with the ipod? It´s because i´m looking for batteries because maybe the problem is with the battery. I have seen batteries of 850mAh but i dont know if they are good or not or if they have more capacity than original ones. Someone knows anything about this?

You really should do a battery life test in the Apple Firmware.  Without that piece of information, everything else is pure speculation.

As my post said, "in Rockbox."  I've never used the Apple firmware for long enough to test the battery.

[Sepharat]

Then i have a problem with my battery. I have done a test with the apple firmware and it runs out in 5 or 6 hours only reproducing music all the time.
Do you know what is the capacity of the original battery and what is the best battery (in capacity) i can find in internet?

It should be stated in your IPOD's manual.

Are you certain about that?  I couldn't see it.  + 5th gen's seem to come with p*ss all in the box!
