高通平台调试cpu

-打印cpu、battery、gpu信息 catcpu.bat

cls
:start
echo cpu:
adb shell cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo*


echo gpu :
adb shell cat /sys/class/kgsl/kgsl-3d0/devfreq/cur_freq
adb shell cat /sys/class/kgsl/kgsl-3d0/devfreq/governor

echo battery:
adb shell dumpsys battery

choice /t 5 /d y /n >nul
goto start

• 打印当前是否省电模式
  root# dumpsys power | grep currently
  Battery Saver is currently: ON

• 固定cpu频率

低电量的时候固定频率没用 只能关thermal
