probeBatteryExtended
Probes extended battery telemetry from BatteryManager and the sticky battery broadcast intent.
Reports charge counter, instantaneous/average current, energy counter, and (on Android 14+) charge cycle count, plus battery technology and plugged state from the sticky intent.
Privacy: battery counters are relatively stable and can aid device fingerprinting; no runtime permission is required.

sticky
The sticky ACTION_BATTERY_CHANGED intent, or null if unavailable.
