Use the "official" library: https://github.com/lewisxhe/AXP202X_Library/blob/master/src/axp20x.cpp#L325 I get stuff like this:

Battery Connected: true       
Battery Charging Enabled: true
Battery Charging: true        
Battery Voltage: 4.19 V       
Battery Percentage: -4 %
Battery Charge Current: 300 mA
Chip Temp: 18.4 C°
