Heltec V3 shutting off at ~ 3.2V battery reading

My unit is shutting down with a displayed reading of about 3.2V only after about 2 or 3 hours of use.
I am using a 1000 mAh battery which should give about 7 or 8 hours of use assuming a current draw of ~ 110mA.
I am not sure if this is related to the Meshtastic FW(2.1.5) or the Heltec Hardware. The battery discharge limit spec is 2.45V.


Heltec esp32 boards require 3.3 volts or higher I believe. I have 8 of them and can say all of them shutdown just slightly under 3.3 volts.

you can set different ADC mulitiplier ratio under power settings.
i forgot the correct value, but it is mentioned somewhere hereā€¦
i was using 2.0 up to 6.0 value, to get full runtime :slight_smile:
