Viewing Battery Use Data

Viewing Battery Use Data

The dumpsys batterystats command generates interesting statistical data about battery usage on a device, organized by unique user ID (UID). The statistics include the following:

• History of battery-related events
• Global statistics for the device
• Approximate power use per UID and system component
• Per-app mobile milliseconds per packet
• System UID aggregated statistics
• App UID aggregated statistics

Use the Battery Historian tool on the output of the dumpsys command to generate an HTML visualization of power-related events from the logs. This information makes it easier to understand and diagnose battery-related issues.

Command input

---

The basic batterystats command is:

$ adb shell dumpsys batterystats

Supported options:

• --help displays additional options for tailoring the output.
• --checkin exports results in machine-readable csv format.

For example, to print battery usage statistics in csv format for all apps since the device was last charged, run the command:

$ adb shell dumpsys batterystats --charged --checkin

You can also specify a package name to get statistics for a single app. For example, to print battery usage statistics for a given app package since the device was last charged, run the command:

$ adb shell dumpsys batterystats --charged <package-name>

Command output

---

The batterystats command generates aggregated observations about battery use on the device since it was last charged. Observations may be per-UID or system-level; data is selected for inclusion based on its usefulness in analyzing battery performance. Output includes one (1) entry per observation, and each entry consists of a comma-separated list of values in the format: int,uid,mode,section,fields (one or more).

The first four values correspond to the following:

• Dummy integer
• UID
• Aggregation mode
  • "i" for information not tied to charged/uncharged status.
  • "l" for --charged (usage since last charge).
  • "u" for --unplugged (usage since last unplugged). Deprecated in Android 5.1.1.
• Section identifier, which determines how to interpret subsequent values in the line.

Bluetooth, cellular, and Wi-Fi usage

---

Support for battery usage data on Bluetooth, cellular, and Wi-Fi data requires the device Bluetooth, cellular, and Wif-Fi chipsets implement radio support and the chipset firmware passes usage data to the framework. OEMs must work with their chipset providers to facilitate in-field firmware updates on existing chipsets and compatible firmware on new chipsets.

Additionally, OEMs must continue to configure and submit the power profile for their devices. However, when the platform detects that Wi-Fi and Bluetooth radio power data is available from the chipset, it uses chipset data instead of power profile data (cell radio power data is not yet used). For details, see Devices with Bluetooth and Wi-Fi controllers.

Note: Prior to Android 6.0, power use for Wi-Fi radio, Bluetooth radio, and cellular radio was tracked in the m (Misc) section category. In Android 6.0 and higher, power use for these components is tracked in the pwi (Power Use Item) section with individual labels (wifi, blue, cell) for each component.
