<![CDATA[Core2: Python API to get battery charge level]]>Is there a Python API to get battery charge level for the Core2 battery?

I found power.getChargeState() but it just returns true/false (charging/discharging). There is also power.getBatVoltage() which could be an indication of the charge level but would need some additional math to calculate the percentage.

I checked on the Core2 and here battery voltage also ranges from about 3.2V to 4.2V.

volt = axp.getBatVoltage()

with

volt = power.getBatVoltage()

Battery discharge characteristics should be the same +/- some small variations independently of battery capacity.

Do you think the table is the same for the M5 Core2?

https://github.com/stonatm/UiFlow-custom-blocks/blob/master/battery-capacity/battery.py

ewentually you could calculate with formula something like this, but it is not accurate.

percentage = int( (battery_voltage - 3.20) * 100)
