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

@thebentern could be related to incorrect INA219 Address ?

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.

gitbisector commented 4 weeks ago

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.

jranma commented 4 weeks ago

Indeed issue happens only when no battery is attached.
