By "latest build", I assume people are referring to b723f81M-120509?
I just installed that so we will see. I still find it odd that the last three builds don't go into "charge mode" but rather only trickle charge. In other words, Rockbox thinks that the Classic is fully charged even though the percentage is below 100%. It still charges this way but I do find that as soon as I unplug, it quickly drops to 94% On the other hand, the previous versions that went into "charge mode showed wildly inaccurate (i.e. low) percentages when plugged in so there was always the danger of overcharging.
Am I the only one who has noticed all of this?
