Do you get charging current? How do you judge it cannot be charged?
I have tried AXP20x samples and battery voltage is around 2.9V and vbus is around 120mA. I have tried to set charge current between 300 and 1000mA with no success. I have tried on usb port, on usb wall charger, i replaced the battery. All without succes. The battery percentage stay at 0% .

@bloutix Please run the AXP202 monitoring example, you can see whether it is normal, if not, please contact customer service
The monitoring example display this values: Vbus: 5057.50mV Vbus: stay beetwen 75mA and 131.62mA BATT: 2960.10mV Per: 0%
Can you tell me the complete display? Or give me a photo
Please update the warehouse to the latest, it contains more detailed information
It looks like the battery is connected. You can unplug the USB, leave the battery in a discharged state, then wait for tens of minutes to let the power drain, and then plug in the USB again to check its charging current
With the original battery charge is at 0.00mA and the bat voltage decrease slowly (around 2800mV), with another battery charge is 0mA or sometime it's at 2mA with a bat volatge around 3270mV
It seems that the charging part may be damaged, please contact LilyGO sales, this can not be repaired by the software.
