Anbernic has the same issue with the RG35XX series. If the battery reaches 0, you may need to pull it out just to get the charging to work. And if you accidentally connect the wrong kind of usb-c charger, it won't charge, so you may have it plugged into the wall for days and come back to it being dead and needing battery surgery.
Great devices for hacking because they are cheap though — cannot understand why an expensive phone would have that problem too.
