The paper investigates the environmental impact of running large language models (LLMs) on mobile devices. It evaluates 18 different LLM configurations on two smartphones and a server, measuring energy per token, latency, accuracy, and battery-cycle consumption. Findings reveal that on-device inference is about three times less energy‑efficient than batched server inference, that energy consumption varies non‑monotonically with quantization bit‑width, and that most models are not on the Pareto front of accuracy and energy efficiency. The study concludes that local AI is not inherently more sustainable than cloud inference, with the majority of environmental impact stemming from device embodied carbon.

SemanticXR is a device‑cloud system that enables real‑time, open‑vocabulary semantic mapping and querying for XR applications while respecting power, bandwidth, and memory limits. By treating semantically identifiable objects as first‑class units, the system coordinates communication, execution, and memory across device and server, achieving a 2.2× faster server‑side mapping latency and keeping upstream bandwidth below 2.5 Mbps. On the device, an object‑level sparse local map with incremental updates delivers sub‑100 ms query latency for up to 10,000 objects, supports tens of thousands of objects within a 500 MB footprint, and adds only about 2 % to idle power.
