For Android 12, batterystats is different.
We now have a file called battery-usage-db-v4.
Now, that v4 could change volume number-wise.
It is going to track the last 24 hours of information that's
killing the battery.
It could contain more.
So as we look here, I can see BatteryState.
We can see the app that's running,
the package name, if it's a hidden app or not,
and the timestamp.
