Battery status

The device uses AXP288 as its PMIC. For some reason, the axp288_fuel_gauge driver isn't working (compile your own kernel with if you think you have better luck). You can, however, get the battery reading using i2cget, and feed it into the test_power module. I've made a script (scripts/battery.sh) to do that periodically.

you should build a kernel with

CONFIG_TEST_POWER=m
CONFIG_I2C_CHARDEV=m

set or m , or y, and the same

[youling 257]

how to use https://sourceforge.net/p/android-x86/kernel/ci/kernel-4.4/tree/  build a kernel with CONFIG_TEST_POWER=m，CONFIG_I2C_CHARDEV=m ？

you mean is edit android-x86_64_defconfig，paste CONFIG_TEST_POWER=m

CONFIG_I2C_CHARDEV=m？paste to what position ?
