I created a Python App that pulls values from /sys/class/power_supply/axp20x-battery then logs the voltage and current to a file. During my test the modem, BT, wifi and front facing camera are switched off. CPU is locked to 480mhz per core with Schedutil power plan active. The battery was charged to ~90% before testing started. Logging is done every 30 seconds.
