PowerRecord: Health Connect power data

What Google says PowerRecord is

Captures the power generated by the user, e.g. during cycling or rowing with a power meter. Each record represents a series of measurements.

Quoted from Google’s PowerRecord Jetpack reference, last updated 2026-06-24, read 2026-10-03.

Permissions

The exact strings Google’s data-types table declares for PowerRecord. Google’s page: “Before requesting any permissions, your app must declare them in the manifest.”

<uses-permission android:name="android.permission.health.READ_POWER" />
<uses-permission android:name="android.permission.health.WRITE_POWER" />

import androidx.health.connect.client.permission.HealthPermission
import androidx.health.connect.client.records.PowerRecord

val permissions = setOf(
    HealthPermission.getReadPermission(PowerRecord::class),
    HealthPermission.getWritePermission(PowerRecord::class),
)

The 6 fields of PowerRecord

Types and descriptions as Google’s reference prints them. The range column quotes Google’s own range annotation or sentence; a dash means Google states none, which is not the same as no validation.

Aggregate metrics

The AggregateMetric constants Google defines on PowerRecord. The value type is the T in Google’s AggregateMetric<T> signature. Every aggregate metric across all records.

Google’s read-data guide: “For cumulative types like StepsRecord, use aggregate() instead of readRecords() to avoid double counting from multiple sources and improve accuracy.” and “The aggregation API also contains logic to handle duplicate records, and lessens the chances of rate limiting.”

Read PowerRecord in Kotlin

The shape of Google’s own read example, with PowerRecord and its names filled in. Get the client with HealthConnectClient.getOrCreate(context) after checking getSdkStatus.

import androidx.health.connect.client.HealthConnectClient
import androidx.health.connect.client.records.PowerRecord
import androidx.health.connect.client.request.ReadRecordsRequest
import androidx.health.connect.client.time.TimeRangeFilter
import java.time.Instant

suspend fun readPower(
    client: HealthConnectClient,
    startTime: Instant,
    endTime: Instant,
): List<PowerRecord> {
    val response = client.readRecords(
        ReadRecordsRequest(
            PowerRecord::class,
            timeRangeFilter = TimeRangeFilter.between(startTime, endTime),
        )
    )
    // One page of up to pageSize records (default 1000); follow
    // response.pageToken for the rest.
    return response.records
}

import androidx.health.connect.client.HealthConnectClient
import androidx.health.connect.client.records.PowerRecord
import androidx.health.connect.client.request.AggregateRequest
import androidx.health.connect.client.time.TimeRangeFilter
import java.time.Instant
import androidx.health.connect.client.units.Power

suspend fun aggregatePower(
    client: HealthConnectClient,
    startTime: Instant,
    endTime: Instant,
): Power? {
    val response = client.aggregate(
        AggregateRequest(
            metrics = setOf(PowerRecord.POWER_AVG),
            timeRangeFilter = TimeRangeFilter.between(startTime, endTime),
        )
    )
    // get() is declared as returning a nullable value.
    return response[PowerRecord.POWER_AVG]
}

HealthKit counterpart

No verified HealthKit counterpart. The cross-platform matrix only pairs metrics checked against both Apple’s and Google’s documentation, and PowerRecord is not among them yet. A similarly named Apple type may exist on the HealthKit reference, but a name match is not a verified mapping.

The metric on other platforms

This guide lists PowerRecord beside the types on the other platforms this site covers whose own descriptions name the same metric, each quoted, with how each one is read.

Questions

What permission does PowerRecord need?

Google's Health Connect data-types table (read 2026-10-03) declares android.permission.health.READ_POWER for reading PowerRecord and android.permission.health.WRITE_POWER for writing it, and says apps must declare permissions in the manifest before requesting them.

Which aggregate metrics does PowerRecord support?

Google's Jetpack reference defines 3 on PowerRecord: POWER_AVG (AggregateMetric<Power>), POWER_MAX (AggregateMetric<Power>) and POWER_MIN (AggregateMetric<Power>). Pass them in the metrics set of an AggregateRequest and read each back from the AggregationResult.

Is PowerRecord an interval, instantaneous or series record?

Google's data-types table lists PowerRecord as Series, and defines that column as indicating "whether the data is recorded at an instant in time or over an interval". Its mandatory fields are endTime, samples, metadata and startTime.
