问题
I'd like to find out various bits of information on an Android device's current status via ADB. Can it be done, and - if so - how?
回答1:
Try this:
adb shell dumpsys battery
It gives all the battery details.
回答2:
IF YOUR DEVICE IS ROOTED
You can use ADB almost like a remote shell, so you can get devices battery info using adb shell cat /sys/class/power_supply/battery/batt_attr_text where "level" is battery level or adb shell dumpsys battery.
adb shell <your command> will let you execute almost any linux command. Some commands are not available and must be installed (e.g. busybox).

Pretty simple and you don't need rooted device for this.
adb shell dumpsys <option>
Subsitute options with any of these: battery diskstats wifi location usagestats cpuinfo iphonesubinfo telephony.registry meminfo netstat package
You may also try adb shell dumpsys | grep "DUMP OF SERVICE"
This will list many other options available with dumpsys.
