⚡ Live Telemetry & Power Tracking
Hero gauge showing real-time Power (W), Voltage (V), Current (mA), Battery Level (%), and Temperature (°C)
Automatic charging profile detection: Ultra Hyper (65W+), Super Turbo (33W+), Fast (18W+), Normal (7.5W+), and Slow charging
Automatic connection type detection: AC wall charger, USB port, or wireless charging
Peak and average wattage tracking for each session, with a one-tap reset
Live streaming graph of the last 60 seconds of power output

🧪 Charger & Cable Benchmark Lab
Save custom test profiles by adapter (e.g. "Xiaomi 90W") and cable (e.g. "6A Type-C") name
Uninterrupted background recording via a foreground service — logging continues in millisecond detail even with the screen locked
Detailed history cards for every saved test: date, time, total duration, start/end battery %, peak watt, and average watt

🔍 Advanced Interactive Graph Engine
Screen-state analysis: periods with the screen locked (ideal test conditions) are highlighted with a green background, with 📱 / 🔒 icons marking transition points
Combined time + battery percentage axis labels (e.g. "17m 23s, 46%")
Point inspection: tap anywhere on the graph for a precise vertical guideline and instant readout (e.g. "19.0 W / 23% 🔒")
Full-screen modal graph with pinch-to-zoom, from 30 seconds (max zoom-in) to 30 minutes (max zoom-out), plus smooth single-finger horizontal scrolling
