After setting the "Charge During USB Connection" Rockbox setting to "no", the battery in my iPod Classic still gets charged whenever connecting the iPod to my PC via USB. From the iPod Video manual:

"This option lets you control whether the player should charge during the USB connection and hence draw the full 500 mA. Turning it Off is recommended if the player is connected through an unpowered USB hub or a laptop port."

I would expect the battery NOT to get charged. Running Rockbox dev build 9576134.
This task depends upon

Yes, I believe that this has been an issue for over a year with this device. Someone attempted a patch, back in 2012. If you know C, take a look at: "FS#12522 - iPod Classic/6G: charger detection"
The patch file there is attached to this post.
