Introduction
Android OS battery optimization has failed for 40% of devices, presenting a significant challenge for user experience and device performance. This analysis will systematically identify, validate, and address the root cause while considering both immediate and long-term implications for Android's ecosystem.
I'll approach this issue by first clarifying the problem's scope, ruling out external factors, and then diving deep into the product's user journey and metrics. From there, I'll form data-driven hypotheses, conduct root cause analysis, and propose validation methods and solutions.
Framework overview
This analysis follows a structured approach covering issue identification, hypothesis generation, validation, and solution development.

Clarifying Questions (3 minutes)
Why it matters: Helps determine if it's a new problem or an ongoing issue. Expected answer: A recent spike in the last 1-2 months. Impact on approach: If recent, focus on recent changes; if ongoing, look at systemic issues.
Why it matters: Identifies if the issue is universal or specific to certain hardware/software combinations. Expected answer: Higher failure rates in budget devices or specific Android versions. Impact on approach: Target solutions to most affected segments or investigate compatibility issues.
Why it matters: Ensures we're addressing the right problem and measuring it correctly. Expected answer: Failure defined as <X% improvement in battery life after optimization. Impact on approach: Adjust analysis based on the specific metrics used.
Why it matters: Identifies potential direct causes of the issue. Expected answer: A recent update to the battery optimization system. Impact on approach: Focus on regression testing and rollback options if a recent change is the culprit.
