## What it is
Battery Historian is a Go-based web tool from Google that analyzes Android bugreport files to visualize battery consumption and system events on a timeline. It supports aggregated battery statistics, per-app battery metrics, and A/B comparison of two bugreports.

## Use cases
- analyze which apps drain my Android battery
- visualize battery events from an Android bugreport
- compare battery usage between two bugreports
- debug excessive battery drain in my Android app
- inspect wakelocks and battery-related metrics on a device
- view aggregated battery stats since last full charge

## When to choose
- you need to diagnose battery drain on Android 5.0+ devices from bugreport files
- you want timeline visualization and per-app battery metrics
- you want to A/B compare two bugreports for battery regressions

## When to avoid
- you need real-time battery monitoring on a live device
- you target Android versions older than 5.0 Lollipop
- you need iOS or desktop battery analysis

## Facets
- artifact type: application
