Based on the above logs, the powersvc provider has stopped, which would cause sensord to stop fetching power readings.

This is a known issue.

Resolution

Workaround : Restart sensord so that it can start collecting the power metrics through its powersvc plugin.

/etc/init.d/sensord restart

This issue is fixed in the upcoming 8.0.3 P05 release.
