[UPDATED] battery draining completely even after ipod has been manually shut off

Well, I turned my alarm off (explicitly), and things have been going better. Now I don't lose power all the time, but it still happens once in a while (like this morning).
In all this time, I've never actually noticed the 'pod powering itself on unexpectedly. You'd think out of the many times this has happened I would have seen the screen come on (or being on after I had shutdown) at least once. I'm a bit skeptical about the alarm diagnosis, but it's true that after turning the alarm off the power loss problem did seem to get better.
--- Quote ---since my last update i have concluded that as long as i do not switch hold on i'm fine. for some reason i only lose power when hold is on.

This is irrelevant for me, since I never use hold. I have a rubber case with a "trapdoor" cover over the click wheel, so I never need hold. And yet I'm having the power problem. And no (for those who might say 'aha' :)), I'm certain it's not that the click wheel is being pressed through the cover. After all this time I've never seen that happen once, in either Apple firmware or RB.

oh well. i thought what had helped me may help you.
and unfortunately, i've been having the problem again recently. i charged my ipod tuesday night, but didn't get a chance to listen to it at work on wednesday. i didn't really think anything about it, but when i attempted to turn it on thursday morning at work it was completely dead.
it was fully charged tuesday night/wednesday morning, hold was off, alarm was off, and i didn't turn it on once, yet it was completely dead thursday morning? i love the fact that i can play my flac files on it, but i think i may just uninstall it and start converting some flac to apple lossless in order to listen on the ipod until the battery problem gets fixed or when rockbox uses less battery power.
oh, and on a full battery i can usually only get about an hour and a half, which unfortunately doesn't usually even last as long as some of the live concerts i listen to. :-\

I am going to jump in here just to say that something is going on since a few weeks ago. Somewhere in early November, I upgraded my rockbox on a ipod video 80GB and weird stuff started happeneing with the power. I would find the battery completely drained coming out of the case, and now it won't charge. I just left it hooked up to the charger all night, and it is almost as if rockbox thinks it is fully charged even though it isn't.
Prior to the upgrade I made in early November (somewhere around the 5th or 6th), I was running a rockbox from earley Octboer and everything worked fine.
I've been playing around trying to get it it to boot into the original firmware to try and get a charge on it, but I keep getting the extremely low battery warning for a few minutes, then it will try to reboot and go back into the low battery warning.
Also, if this is helpful, before the battery fully drained last night, I upgraded to the current build of around midnight EST. Now, I can't even get into disk mode to try downgrading to an older tarball.
(Soap merged two posts. Do Not Double Post in the future!)
SO I plugged it into my dock/charger and got it to boot into the Apple firmware, which is reporting the thing is fully charged even though it isn't. Is this a known issue with Apple firmware? Google hasn't turned up anything for me yet.

Just thought I'd follow up this thread again..... I've been continuing to test. I am still occasionally having the "battery drain" symptom, although as I think someone above noted, it is a "fake" symptom. I can in fact reboot the 'pod and have it work, with the battery showing roughly (I think) the charge it had when I shut it down. So somewhere there is a signal being sent that the battery is dead even though it's not. I'm quite sure, however, that when this first started happening to me, a simple reboot did not work to fix it (on the other hand, that was probably an earlier software version).
I have been trying to find a pattern in order to clarify this problem, but have not been able to find one. The best I can say is that the likelihood of the fake battery drain syndrome seems to increase the longer I leave the machine without starting it. It does not seem to be related to the amount of charge in the battery. Still, there's nothing reproducible yet.
I would love to work closely with a 4G developer to isolate this bug and put it to rest once and for all. I'm good at doing careful testing :) Please contact me if you're such a developer...

Just to confirm that I'm having the same issues with my 4g 40go ipod.
I've not been able to understand when exactly it was happening, but once I see the "no battery" icon during boot process, my ipod shuts down and refuse to do anything else (blank screen, no reaction) until I plug it in again.
Actually, the only real workaround I found is not leaving my flat without charger and cable!
I'll get back to you if I'm able to get some more info...
And thanks for Rockbox: it's so good I'm still using it even if I have this problem since a month or so, when I first installed it! ;)
