These events gather battery data for or related to the following information:

• state of health

• cycle count

• event counters

• charge termination

• lifetime maximum/minimum values for current/voltage/temperature

• battery manufacturer

• permanent failure flagging

• battery serial number

• battery level in rolling time windows

Microsoft.Surface.DeviceCensus.Prod.Info

This event gathers census information about Surface devices to Microsoft. The event includes basic hardware information, telemetry opt-in status, system image name, and Surface management policies.

Microsoft.Surface.DtsCritical.Prod.AccessoryCriticalLog

This event is the critical log of accessory firmware. It is only collected when accessory firmware run into a fault state, mostly a crash. The critical log will only be used to analyze why the fault state occurs and to provide the solution to fix it.

Microsoft.Surface.DtsHealth.Prod.AccessoryHealthLog

This event is the health log of accessory firmware. The health log is a list of indicators that are used to monitor the health of the accessory firmware and the value of each indicator increases when certain conditions are met.

For example, TEMPERATURE WARNING indicator increases when the temperature of the accessory is higher than the threshold. The health log will be used to monitor the health of the accessory firmware so that we can take actions to prevent the accessory from running into a fault state.
