I recently purchased a Peacock Stone radio (version 1.10d) on Xianyu. I've discovered that charging seems to be malfunctioning. When using the C port to charge while the radio is OFF, it automatically turns ON and cannot be turned OFF. The charging light turns red, and the voltage displayed in the upper right corner shows 4.15V, but after approximately 4 hours of charging, the charging status is not indicated. The charging light remains red. When I unplug the charger, the upper right corner displays either red or yellow, with a voltage of 3.5V. I suspect that the radio may not be charging at all.
I would like to ask experienced users of Peacock Stone radios: What is the normal charging state for a Peacock Stone radio? Does it automatically turn ON while charging? When charging is complete, does the red charging light turn OFF? What does the power and voltage indicator in the upper right corner display when the radio is turned ON after charging?
I asked the person who sold me the Peacock Stone radio, but he was unable to answer these questions. Therefore, I am seeking help from everyone. Below are images showing the radio's version, the charging status at stages 1, 2, and 3, and the state after 4 hours of charging.
