No. He has not solved his problem in the video. Watch it again. He shows the problem with three different chargers. There is a comment from another user that they changed chargers and yet another user that he/she has the problem with three different chargers.
I have the problem with three different cables and five different chargers.
Look at the symptoms:
* you do not have the problem with android
* if you boot android and then switch to windows, you do not have the problem until the next time you disconnect/reconnect the power
* if you disable the "intel battery management" driver in the device manager, the tablet stops cycling on/off power. When you re-enable the driver, it starts cycling again.
Does it not sound like an initialisation problem in the driver ? If so, this could be fixed. Unfortunately, there is no evidence that chuwi have driver expertise in-house.
