As I know D10 use Li-ion battery, so it have no memory effet just like most mobile phone now a day. I charge my iPhone everynight - overnight, regardless how the battery remain, on some weekend I leave it connected to the AC adapter all day long, while I still using it.
In the D10 user manual it said
"When the power lamp is flashing, the battery needs to be charged. Charging is accomplished with either the furnished USB cable or AC adapter. Make sure the charge switch is turned to On position. It usually takes about 6 hours to charge a completely drained battery. When the charge lamp turns to orange color, the D10 starts charging. At the point the charge lamp goes off, the battery is fully charged. the D10 has overcharge protection; you can leave the D10 plugged and no over-charging concerns. In order to extend the battery life, please always keep the charge switch on Off position when it does not need to be charged."
The statement above is quite clear, but not cristal. The point is, How the D10 know that it's battery is completely charged?. Is it timer charged or it detect heat or it detect delta Vcc negative to said the battery is completely charged?
Regards,

Ting, I'm not sure if iBasso monitors this forum that often, so you may want to email them directly.
That being said, the red charge light will go off when it's charged completely.
In some cases, I've found that certain usb ports don't have a high enough power for the LED to turn off, even after 6+ hours. So, that tells me that it's NOT timer based.
Even this happens and I've charged it for ~6 hours (if the D10 was fully discharged), I know it will be charged completely. I'll unplug the D10 from the usb cable, and when I plug it the cable back in, the red light will remain off.
Sorry, that's the best I could do with the information that I have.
