With Josh Hickman finally releasing his Android 12 test image, we have more new things to hunt down. Something new that I came across is more battery usage items, this time found here:
data\data\com.google.android.settings.intelligence\databases\battery-usage-db-v4
This SQLite database seems to correlate to the Settings Services:
https://play.google.com/store/apps/details?id=com.google.android.settings.intelligence
If you navigate to Settings > Battery > Battery usage, you will see a similar page that lists application usage for the past 24 hours. It also gives you application breakdowns per app with total usage in time, background usage as well as a percentage overall.
Figure 1: Settings Services Battery Usage
Each two hour interval is clickable as well which shows an even more granular breakdown for a smaller timeframe.
Opening the database file there was only one table of interest, BatteryState. Inside we get some useful columns:
- appLabel - application name
- packageName - package name of the application
- bootTimestamp - offset in milliseconds of the boot time of the device. I believe this is the last time the phone started up (restart or power on), more testing needs done to verify
- timestamp - timestamp of when the Settings calculated the entry
- zoneID - timezone (ex. America/New_York)
- totalPower - my assumption here is total mAh available at a point in time
- consumePower - amount of mAh used by an app at a point in time
- percentofTotal - percentage total of battery usage per application
- foregroundUsageTimeInMs - usage of an app in the foreground in milliseconds
- backgroundUsageTimeInMs - usage of an app in the background in milliseconds
- batteryLevel - the percentage of battery available at a point in time
- batteryStatus - appears to show if the device is charging or not, assumptions based off test data:
- 2 = Charging
- 3 = Not Charging
- 5 = Fully Charged
