Question

我有一个扎根的Galaxy S6，我想修改设备的电池百分比以进行测试。我希望Android'认为'它有X％电池...... 我已经发现百分比存储在：

/sys/class/power_supply/battery/capacity

但是当我尝试修改文件时，它说：

tmp-mksh: can't create capacity: Permission denied

即使我以root身份尝试...... 有没有办法修改电池的百分比？

编辑：我也试过了：

C:\Users\Valentino>adb root
adbd cannot run as root in production builds

C:\Users\Valentino>adb shell
shell@zerolte:/ $ su
su
root@zerolte:/ # setenforce 0
setenforce 0
root@zerolte:/ # echo 45 >> /sys/class/power_supply/battery/capacity
echo 45 >> /sys/class/power_supply/battery/capacity
tmp-mksh: can't create /sys/class/power_supply/battery/capacity: Permission deni
ed
1|root@zerolte:/ #

它也不起作用......

Answer 1

您可以使用以下命令：

adb shell dumpsys battery set level 30

重新恢复原始电池电量，请使用：

adb shell dumpsys battery reset

Answer 2

Try the below commands which might help you.

adb root
adb shell
su
setenforce 0
echo 45 >> /sys/class/power_supply/battery/capacity

This will change the battery level to 45% and it worked fine for me. :)
