Battery Drain Analyzer

What if you could see exactly what drains your Android battery?

Battery Drain Analyzer by SunLight provides a technical breakdown of your device's power consumption. This utility app moves beyond basic percentage readings to deliver a forensic analysis of battery health and usage patterns. It functions as a diagnostic tool, presenting data through persistent notifications and customizable home screen widgets for constant monitoring without needing to open the application.

Core Analytical Features and Operational Modes

The application processes battery data to generate a 30-day statistical history, allowing for trend analysis of capacity fade and discharge cycles. It calculates two key projections: a remaining runtime estimate based on current usage and a time-to-full-charge forecast when the device is plugged in. The system employs three distinct operational profiles—Day, Night, and Saver—each with pre-configured settings for display brightness, timeout intervals, and background process management tailored to specific scenarios.

The primary interface is a persistent notification shade display, ensuring battery metrics like voltage, temperature, and health percentage are always accessible. Users can supplement this with either a compact 1x1 or an expanded 2x1 widget for direct desktop viewing. The application's structure is built around providing granular, actionable data rather than automated optimizations, placing control directly with the user.

• Historical Trend Analysis: Tracks and graphs battery level, temperature, and health statistics over a 30-day period for detailed performance review.
• Dual Predictive Calculators: Generates independent estimates for remaining battery life under current load and time required to reach a full charge.
• Context-Aware Power Profiles: Offers three switchable modes (Day, Night, Saver) with specific settings for screen and system resource management.

Consider downloading Battery Drain Analyzer if you require detailed, factual insights into your Android device's power consumption and long-term battery health.

An active internet connection may be required for certain functions. The application may offer optional in-app purchases.
