Thanks this worked on my CM4  
(Assuming i can trust cat /sys/class/power\_supply/axp20x-battery/constant\_charge\_current)

hmm maybe this is better  
alex@uConsole:~ $ cat /sys/class/power\_supply/axp20x-battery/uevent  
POWER\_SUPPLY\_NAME=axp20x-battery  
POWER\_SUPPLY\_TYPE=Battery  
POWER\_SUPPLY\_PRESENT=1  
POWER\_SUPPLY\_ONLINE=1  
POWER\_SUPPLY\_STATUS=Charging  
POWER\_SUPPLY\_VOLTAGE\_NOW=4173000  
POWER\_SUPPLY\_CURRENT\_NOW=680000  
POWER\_SUPPLY\_CONSTANT\_CHARGE\_CURRENT=2400000  
POWER\_SUPPLY\_CONSTANT\_CHARGE\_CURRENT\_MAX=2400000  
POWER\_SUPPLY\_HEALTH=Good  
POWER\_SUPPLY\_VOLTAGE\_MAX\_DESIGN=4200000  
POWER\_SUPPLY\_VOLTAGE\_MIN\_DESIGN=3300000  
POWER\_SUPPLY\_CAPACITY=85  
POWER\_SUPPLY\_ENERGY\_FULL=8000000  
POWER\_SUPPLY\_ENERGY\_NOW=7500000
