aroldan, I think that rockbox-ipod6g-a3406a8M-120529 is a winner. It is snappy and responsive.
The charging works well. I still have the strange underestimated battery percentage during charge. (I think that this is a bug inherent in the Classic's Rockbox code). However I can just plug the Classic in and leave it. It charges perfectly and stops when finished with the display showing the correct 100%.
Battery life also seems to be excellent. I tested playing two full albums which took it from about 98% to 92%. Lastly, while I am not certain that I can hear a difference between different builds (maybe if I could do a true A/B...), it certainly sounds excellent which is all that matters.
Great job. This is my new current install until you work more of your magic. :-)
