01. Select the right device
Connect your Android target in ADB Companion. Check the name in the terminal’s device selector, especially if you have more than one saved device.
A battery snapshot is a useful first check when you want to see what Android reports about charging. It does not measure long-term battery capacity or prove what is causing battery drain.
02. Read the battery service
Run the command below in Terminal, or choose Battery status from the starter actions. It reads the battery service state without changing it. The result appears as a card, with a timestamp and the originating device.

Look for charging-source fields such as AC powered and USB powered, along with level and scale. The exact output depends on the Android build and hardware.
Treat this as one observation at one moment. For troubleshooting, note whether the device was charging and what you were doing when you captured it. Avoid reset, set, or unplug subcommands for this read-only workflow; those can change the battery service’s test state.
04. Save the useful check
Favorite the command from its result, or pin the Battery status starter action. Use Run again to capture another snapshot after a change.
Use History to find earlier commands and open their captured output. If you share a result with someone helping you troubleshoot, review it first. Results stay in the app unless you choose to copy, share, or export; history retention settings determine how long they remain available.
One more useful thing in your toolkit.
Keep the commands you use. ADB Companion will keep them close.
