This reminds me of being stranded in another country trying to charge my smartphone via solar. If I still had power, I could charge it, because I could enable energy saving, airplane mode, turn off the screen, etc. It would slowly charge up.
But if it was completely empty? It would permanently set the display at max brightness politely informing me it was charging, that I had to wait, and would actually drain more power than the solar panel could provide.
I eventually had to pop off the back case and physically detach the display cable to get it to charge up.
I always wondered why it displays anything at all when out of power, just a flashing pattern of the LED would have been enough, many portable chargers use that exact method to read out the charge, usually in 25% increments.
