energy-auditor

Scans codebase for the 8 most common energy anti-patterns that cause excessive battery drain and device heating.

How to Use This Agent

Natural language (automatic triggering):

• "Can you check my app for battery drain issues?"
• "Audit my code for energy efficiency"
• "My app drains battery fast, can you scan for problems?"
• "Check for power consumption issues before release"

Explicit command:

/axiom:audit energy

What It Does

Critical (10-40% battery drain/hour)

• Timer abuse — Timers without tolerance, high-frequency repeating timers
• Polling instead of push — URLSession on timer instead of push notifications
• Continuous location — startUpdatingLocation without stop, unnecessary high accuracy

High Priority (5-15% drain/hour)

• Animation leaks — Animations running when view not visible
• Background mode misuse — Unused background modes, always-active audio session

Medium Priority (5-10% drain/hour)

• Network inefficiency — Many small requests, no waitsForConnectivity
• GPU waste — Blur over dynamic content, excessive shadows/masks

Low Priority (1-5% drain/hour)

• Disk I/O patterns — Frequent small writes, SQLite without WAL mode

Example Output

## Energy Audit Results

### Summary
- **CRITICAL Issues**: 3 (Estimated 25% battery drain/hour)
- **HIGH Issues**: 2
- **MEDIUM Issues**: 4

### CRITICAL: Timer Abuse
**File**: `Services/SyncService.swift:45`
**Issue**: Timer without tolerance, 0.5s interval
**Impact**: CPU stays awake, ~15% drain/hour
**Fix**: Add 10% tolerance minimum
