I have an Lollipop EDC. That Android has battery with 6 pinouts. How to get information about battery pin-out via ADB?
You can query get all information Android has about your battery by executing
adb shell dumpsys battery
Then you will get an output like this:
Current Battery Service state: AC powered: false USB powered: true Wireless powered: false Max charging current: 400000 Max charging voltage: 5000000 Charge counter: 1363859 status: 2 health: 2 present: true level: 51 scale: 100 voltage: 3833 temperature: 190 technology: Li-ion
I don't know how and if it is possible to get other details on the battery such as the type number (e.g. for buying a replacement). If you require such information I would check if there is a tear-down video e.g. on https://iFixit.com for your device that includes such information.
