Running FW 3.2.2 on a lilygo-t-display-s3. Works fine via USB, but under battery power LCD is powered off. GPIO15 must be set HIGH for LCD to turn on when powered only by battery.

Also, battery voltage is not reported correctly Screenshot 2024-03-14 120443

Thanks for the finding. GPIO15 will be set HIGH in the next version. 0.0 V cannot be fixed because the BAT_ADC is connected to BAT and not to VBAT (see the schematic)
