Can you try the ADC Multiplier Override calibration process? https://meshtastic.org/docs/configuration/radio/power/#calibration-process-attribution

unfortunately, didnt help. playing with power settings doesnt help.
does anyone have a clue about this?
Just made a clean reflash, using 2.3.13.
USB power not detected using factory settings.
display:
- UNK%
- UNK volts
My t-beam S3 supreme runs 2.4.1 and showing the plug icon (4.18V) on both the display and IOS app. Do you have a 18650 cell in the back too? Am using an Samsung unprotected 18650.
Seems to be an IOS app thing. It shows battery 0% when on USB without battery plugged in. When the battery is present it shows 'PWD' on the app. Debug output from the T-Beam S3 supreme follows.
With the battery removed:
DEBUG | 20:10:56 89 [Power] Battery: usbPower=1, isCharging=0, batMv=0, batPct=0
With the battery present:
DEBUG | 20:12:36 189 [Power] Battery: usbPower=1, isCharging=1, batMv=4184, batPct=14%
The device metrics packet is a percentage from 0-101 with 101 meaning powered.
While on USB power, without a battery present, the wrong status is getting reported. Should probably fix it then to send '101' in this state as the device is able to recognize the difference.
