Yes, i used normal chargers (have many of them) as well and i left them over night before. one more observation: charging the digital battery only works when it shows charging in the lock screen. That was the case yesterday too, tried many times, no charging in the lock screen = only analogue charging, once in the evening, lock screen shows charging, left it over night, result in the morning, analogue 100 %, digital only 86 %, no more charging.
Once i started charging, digital at 19 %, left it charging over night, next morning digital battery was at 0 %.
i don´t give much on the german distributor, i think they were able to charge it once and sent it back, i don´t know how many times they tried it before...
I think there are 2 possibilities:
- a faulty digital battery
- a problem in the charging mechanism, switching from one battery to the other
The charger and the cable are ok imo, because it charges the digital battery (sometimes). I think only
@Paul - iBasso and the dev-team are able to help.
i hesitate to send it back to my dealer because i know that i´m without the DX320 for many weeks, especially when they will send it to Ibasso China.
I still hope there´s another solution, maybe a firmware issue....
