Hardware

Every decision below follows from one requirement: a capable model has to stay in memory, all day, without the phone getting hot or the battery dying by lunch. That requirement is unusual, so the phone is unusual.

Endurance

Sustained agent useAbout 6 hours of continuous generation
Idle with model residentAbout 40 hours
Charge65 W wired, no wirelessheat budget went to the NPU

What it does not have

No wireless charging, because the coil competes with the thermal path the NPU needs. No periscope camera, because the space is memory. No cloud account, because there is no cloud. The phone is worse than its competitors at most things and better at exactly one.

Concept hardware for a portfolio piece. None of these components have been sourced and no device exists. The numbers are internally consistent, not manufacturer quotes.
