Device Configuration

Quick starts

Battery capacity 850 mAh Physical size scales with capacity. 850 mAh ≈ 12g, 12mm thick cell.

Compute tier T2 — 2 TOPS On-device inference capability. Higher tiers need more cooling.

Cellular modem LTE-M Always-on connectivity for cloud fallback. Impacts idle drain significantly.

Thermal solution Graphite + vapor chamber Thermal resistance junction-to-ambient. Lower = better sustained performance.

Workload profile Conversational Typical usage pattern. Affects average power and thermal cycling.

Ambient temperature 25°C Operating environment. Higher ambient reduces thermal headroom.

How to read the simulation

Battery life

Calculated from total capacity divided by average power draw across all subsystems. Includes idle drain, active compute, modem transmission, and thermal solution overhead. Real-world variance ±15%.

Thermal throttling

When SoC junction temperature exceeds 85°C, the simulator reduces compute frequency. Throttle time shows percentage of active minutes spent throttled. Sustained throttling degrades user experience.

Cloud latency

Round-trip latency for cloud fallback requests. LTE-M adds 80–150ms; 5G adds 30–60ms. On-device inference has ~10ms latency. The workload profile determines fallback frequency.

Heat flow visualization

The cross-section shows real-time heat generation (orange/red) and dissipation paths (purple pipes). Particle density = heat flux. Color intensity = temperature. Watch for hotspot formation near SoC.

Preset configurations

Minimalist — Maximum battery life, cloud-only. Balanced — On-device for common tasks. Performance — Maximum on-device capability. Always-connected — 5G + active cooling.
