Why Apple's Smart Glasses Keep Getting Delayed

TL;DR

Apple N50 smart glasses slipped to WWDC 2027. Blockers: chip and heat limits in a 40g frame, camera privacy risks, and a market Meta already dominates.

In February 2024, Apple terminated Vision Pro production. A project that consumed over a thousand engineers and tens of billions of dollars ended with roughly 600,000 units sold globally — the original target was 10 million units by year three. The core lesson is simple: cramming everything into one headset isn't feasible in the 2020s. Resources and supply chain have now fully pivoted to smart glasses.

Dilemma #1: Technology — A 40-Gram Frame Can't Fit an iPhone

Stuffing a chip, camera, microphone, speaker, and battery into a 40-gram glasses frame and then running AI models on it — that's the bonus question on the physics exam.

Battery life is the first gatekeeper. Smart glasses batteries typically range from 150–300 mAh. AI glasses with cameras consume roughly 300 mW at the chip level under high load, yielding a real-world battery life of 2–4 hours. Xiaomi's AI glasses lead put it bluntly: running a 0.3B on-device model on a 200 mAh battery is "devastating" — it can drain the battery in 30 to 60 minutes.
