Energy Optimization

Overview

Energy issues manifest as battery drain, hot devices, and poor App Store reviews. Core principle: Measure before optimizing. Use Power Profiler to identify the dominant subsystem (CPU/GPU/Network/Location/Display), then apply targeted fixes.

Key insight: Developers often don't know where to START auditing. This skill provides systematic diagnosis, not guesswork.

Requirements: iOS 26+, Xcode 26+, Power Profiler in Instruments

Example Prompts

Real questions developers ask that this skill answers:

1. "My app is always at the top of Battery Settings. How do I find what's draining power?"

→ The skill covers Power Profiler workflow to identify dominant subsystem and targeted fixes

2. "Users report my app makes their phone hot. Where do I start debugging?"

→ The skill provides decision tree: CPU vs GPU vs Network diagnosis with specific patterns
