1. View the package name and class name of the currently running software:
adb shell "dumpsys window | grep mCurrentFocus"
2. Enter the adb shell:
adb shell
3. Check the CPU usage:
top | grep 包名（只查看指定包名的CPU占用率）
或
top -m 10 -s cpu(-m 显示最大数量，-s按指定排序)
使用时要把CPU换成9，因为会报 top: not integer: cpu
adb shell top -s命令只支持0-X数字，默认9，猜测分别指代
0 , 1 ,3 , 4, 5 , 6 , 7 ,8, 9 , 10 , 11 , 12
PID,USER,PR,NI,VIRT,RES,SHR,S,%CPU,%MEM,TIME+,CMDLINE
top -m 10 -s 9(-m 显示最大数量，-s按指定排序)
User 46%, System 40%, IOW 0%, IRQ 0% //CPU usage
User 84 + Nice 1 + Sys 75 + Idle 24 + IOW 0 + IRQ 0 + SIRQ 0 = 184 // CPU usage
4. View memory usage:
dumpsys meminfo | grep 包名
5. View power consumption:
dumpsys battery
AC powered: false Whether to connect AC (power supply) charging cable
USB powered: true Whether to connect to USB (PC or notebook USB socket) for charging
Wireless powered: false Whether to use wireless power
status: 2 Battery status, 2 is charging status, others are non Charging status
level: 85 Power (%)
scale: 100. Maximum power value
voltage: 4180 Current voltage (mV)
current now: -335232. Current current (mA)
temperature: 290 Battery temperature, the unit is 0.1 degrees Celsius

7. Frames per second (fluency) [fps]:
dumpsys gfxinfo 包名
PS: It is best to enter the Android system through the adb shell first, and execute the statement after the adb shell. Replace grep with find in the dos window of windows system
