RK3288 manually sets the battery charge
System version: RK3288 android 5.1 (slightly different from referenced variables and macros)
The device does not have a battery. During the Fota upgrade, it is suggested that the battery should not be less than 30%, with an external power supply, but the read power is 0%, so you can only manually set the battery charge.
$adb shell dumpsys battery / / query battery information through adb
