Battery health

The battery health report provides visibility into the health of batteries in your organization's devices and its influence on user experience.

The score helps you identify emerging hardware issues that might be impacting user productivity so you can proactively make improvements before users generate support tickets.

The insights show how much your score can improve by replacing batteries in affected devices. They also help you identify quickly failing batteries that can be replaced under warranty before they expire.

Licensing Requirements

The battery health report is part of Intune Advanced Analytics features and is included as an Intune-add on under Microsoft Intune Suite. It requires an extra cost to the licensing options that include Microsoft Intune.

Prerequisites

In addition to the prerequisites for Advanced Analytics, this report also requires that devices need to be battery-powered for them to show up in this report.

For Advanced Analytics capabilities, including battery health, battery-powered devices should be either Intune-only managed or Co-managed.

After enrollment, client devices require a restart to fully enable all analytics.

Battery health report

1. Sign in to the Microsoft Intune admin center.

2. Select Report > Endpoint analytics > Battery health.

3. The Battery health report page shows an Overview tab, Device performance tab, Model performance tab, OS performance tab, and an App impact tab. For more information on each of the tabs, see Reporting Tabs.

   

Battery Health Score

The battery health score gives an overview of laptop battery health. It's calculated as a weighted average of your organization's battery capacity score and battery runtime score, helping you identify batteries that need replacement.

The maximum capacity of a battery is the ratio of its full charge capacity against its design capacity. The full charge capacity shows the Watt-hours the battery can hold on a full charge now, while the design capacity shows the Watt-hours the battery could hold when it was new. For example, a maximum capacity of 50% on a battery with design capacity of 70 Watt-hours means that the battery now holds only 35 watt-hours on a full charge.

Battery capacity score: Based on the maximum capacities of batteries in your organization's devices, we create a score from 0 (poor) to 100 (exceptional). Your battery capacity score is the average for all devices.

The estimated device runtime is an estimate of the amount of time a device runs using a battery on full charge and assuming the system's usage pattern is comparable to when the device was plugged in. The Battery capacity score is calculated from the combined battery capacity and estimated battery drain rate.

Battery runtime score: Based on the estimated device runtimes for batteries in your organization's devices, we create a score from 0 (poor) to 100 (exceptional). Your battery runtime score is the average for all devices.

Insights

The Battery health page provides a prioritized list of Insights and recommendations, described in this section:

Low battery capacity: These devices have batteries that hold less charge compared to what they were designed to hold. Devices with battery capacities below 60% are considered most impacted whereas devices with battery capacities between 60-80% are considered moderately impacted. The insights might contain one of these conditions independently or in combination with low runtimes.

For example, some devices might have batteries with below 60% capacity but still provide reasonable runtimes because their design capacities are high. Whereas other devices might have batteries with below 60% capacity and less than 3 hours of runtime, in which case they're a part of insights that highlight both gaps together.

Low estimated runtime: These devices result in poor user experience as they must be plugged in frequently. Devices with battery estimated runtimes below 3 hours are considered most impacted. Low runtimes are typically reported in combination with battery capacities.

Devices with less than 3 hours of runtime usually have poor maximum capacities and are included in insights that highlight both issues together. The exception is seen in the following scenario where even with high capacities, the batteries drain quickly because of power hungry apps. Either by design or because of poor energy usage efficiency.

Good battery capacity but poor runtime: Estimated runtimes might be low despite batteries having good maximum capacities. Low runtime is possible in two scenarios:

1. The device is running apps that drain the battery quickly. Users run applications that consume high power or inefficiently use power and need upgrading or replacing. Battery-powered devices can use the battery saver Windows feature to ensure that both user productivity and experience are protected.

2. The device has a battery that is designed to hold low charge. Procurement teams drive this decision.

Insights for this scenario highlight the devices for which the App Impact tab might provide more visibility into whether the user needs to use power hungry apps or whether the app's battery usage is unusually high due to inefficiency.

Reporting Tabs

The Battery health page has reporting tabs that provide support for insights. The tabs are described in this section:

Device performance tab

This tab provides battery health metrics and a score for all your battery-powered devices. You can sort by a particular metric (for example, Max capacity) to see which battery-powered devices have the worst scores for that metric to help with troubleshooting. You can also search for a battery-powered device by name. If you select a battery-powered device, you can see its runtime trend, its score vis-à-vis the model's average score in the organization, and the top apps that consumed its battery in the last 14 days. These details can help you identify any corrective actions needed to improve the user experience.

The cycle count is the number of times the battery discharges 100% of its capacity, but not necessarily at one time. For example, if a battery discharges 50% of its capacity on day 1, 30% on day 2, and 20% on day 3, then its cycle count goes up by 1 after these three days.

Model performance tab

This tab shows battery health metrics and scores by device models, helping you identify if problems are specific to certain models.

Operating systems performance tab

This tab lets you see the battery health metrics and scores by OS versions, which can help you identify whether problems are isolated to particular OS versions.

App impact tab

This tab lets you see the organization's cumulative battery usage per app in the last 14 days. You can see the number of battery-powered devices for which the associated battery usage of an app and the percentage of the cumulative battery charge that the app consumed is recorded. This information helps to troubleshoot apps that might be consuming an inordinate amount of battery.

Outliers

Estimated runtimes are sometimes not available for battery-powered devices where we don't have enough information on battery drains.

If the battery design doesn't report cycle count, then the report won't contain cycle count information for such battery-powered devices.

If battery is new, we might not have enough data on the cycle count in which case a zero with an asterisk appears as the cycle count.

In rare cases, the battery count might exceed 2, indicating that devices are plugged into UPS or other external batteries. Since this is unusual, we add an asterisk (*) if the count exceeds 2.

Limitations

Some data points in the report might say Not available. When you export the report, data points that aren't available appear as "-1" in the generated .csv file.

Batteries that have low design capacity (For example, devices designed to hold limited charge) show up as having low runtime although this feature is by design. Such devices are counted under low runtime insights and the only solution is to replace the battery with one that holds more charge.
