ipod classic gen6 - improving your battery life

[ignoramus]

Just an observation, but I found that when I installed the latest version of rockbox (on my 160GB ipod), the battery consumption seemed excessive.

I'm not 100% certain, but I think the battery in the latest ipod classic gen 6 video is 850 mAh.

When you install rockbox the default setting for v3.13 will be set at 550 mAh.

You can change this to 850mAh from the main menu in:  settings|general settings|system|battery

It's early days but my battery seems to be lasting significantly longer than before I modified that setting.

By my understanding that will have absolutely zero impact on runtime. I suspect you created yourself a rather nice placebo effect, you believe it works the way you think it does, so you see an effect that doesn't actually exist.

This is only used for runtime estimation, which is slightly buggy/wrong anyway, and wouldn't give a correct value for this target even if it was set to the correct value.

I do have a patch that will detect if the device is the CE-ATA "thick" 160GB Classic (it is only this model that has the 850mAh battery I believe), and set this value accordingly, which I should remember to push, but as noted above it is of little importance.

That's correct. Also, there is no 3.13 for the 6g...

   You are probably right Saint.  I'm just a beginner with all this stuff.

I can confirm though, that the version I have installed is 9e7bd64-130313.

seems to work very well - has "frozen" a couple of times but a reboot fixes that and it's not frequent enough to be of real concern.

I guess I installed that version because it was for the ipod video - which I thought was either 5G or 6G versions.

Looks like there is a current 6G version and Saint has already directed me to it in another post.
I will try it.

3.13 has been really good, will be interesting to compare.

the version I have is the latest for 6g:  9e7bd64-130313

Target: ipod6g
Target id: 71
Target define: -DIPOD_6G
Memory: 64
CPU: arm
Manufacturer: s5l8702
Version: 9e7bd64-130313
Binary: rockbox.ipod


There is also a version for the ipodvideo and that is 3.13:

Target: ipodvideo
Target id: 15
Target define: -DIPOD_VIDEO
Memory: 64
CPU: arm
Manufacturer: ipod
Version: 3.13
Binary: rockbox.ipod


To clarify - I'm not sure now if I've even tried it. I thought that version 3.13 might have been an abbreviation for version 9e7bd64-130313.

My mistake, hope it didn't confuse anyone.

Like gevaerts said, there is no 3.13 for your player, so I don't think anyone really thought you'd installed it.

I think our version numbers are confusing you...

The way to read it is:

<9e7bd64>-<13><03><13>
<7 digit git commit hash>-<day><month><year>

So, 13 March 2013, which is in fact 8 days shy of being "the latest build" as of the time of your posting.

Perhaps the link I gave you earlier (in another post) confused you, it is not a link to a specific version, it is a link to "the current build" which can sometimes change several times per day. It is the absolute bleeding edge, the build from that link is refreshed on each source commit.

The other thing that you, or perhaps I, seem to be confused about is the build type installed on the device. I can say that if you did manage to install an iPod Video (5G) build on the device, it most certainly didn't ever boot, so I think it fairly safe to say at least one of us got some wires crossed somewhere.
