Unknown option: --help
Battery stats (batterystats) dump options:
  [--checkin] [--history] [--history-start] [--unplugged] [--charged] [-c]
  [--reset] [--write] [-h] [<package.name>]
  --checkin: format output for a checkin report.
  --history: show only history data.
  --history-start <num>: show only history data starting at given time offset.
  --unplugged: only output data since last unplugged.
  --charged: only output data since last charged.
  --reset: reset the stats, clearing all current data.
  --write: force write current collected stats to disk.
  <package.name>: optional name of package to filter output by.
  -h: print this help text.
Battery stats (batterystats) commands:
  enable|disable <option>
    Enable or disable a running option.  Option state is not saved across boots.
    Options are:
      full-history: include additional detailed events in battery history:
          wake_lock_in and proc events
      no-auto-reset: don't automatically reset stats when unplugged
