"12-hour battery," says Halliday. "Incredibly optimistic," says the reviewer wearing them.

At CES 2025 Halliday told the press its smart glasses would ship in March at $489, then raised more than $3.3 million on Kickstarter and about as much again on Indiegogo. Engadget's review puts actual retail shipping at the end of October, at $499. The COO's account of the slip: "we didn't speak [the manufacturer's] language." Android Police then tested the advertised 12-hour battery and called it "incredibly optimistic" — reachable only if you catch a few notifications and do "absolutely nothing else." Two promises, two paper trails.

Claims

#1 Halliday, CES 2025 plan as reported by 9to5Google said on 2025-01-05 · source

Halliday will start shipping in March 2025 with a starting price of $489.
Partially contradictedVersion 2 · Model qwen-max · verdict_v1 · hardware-startups@2 · 2026-09-23 06:19

While the pricing claim is supported by an independent source, the shipping date is contradicted. The evidence indicates that shipping actually began at the end of October, not in March as initially claimed. This aligns with the base rate of startup delays and Kickstarter project delivery statistics.

What would change this

  • An independent source confirming the initial March 2025 shipping promise from Halliday.

#2 Halliday official website (archived 2025-05-27) said on 2025-05-27 · source

Up to 12 hours of use and 100+ hours fo standby time mean Halliday works as hard as you do.

The Halliday website did claim a 12-hour battery life, which is supported by an independent review. However, the same review found that the actual battery life was significantly less, contradicting the 12-hour claim. The discrepancy between the claimed and observed battery life also fits with the constraint pack's note on how lab conditions can differ from real-world use. Since there is a contradiction, the overall level of support for the claim is 'partially_contradicted'.

Citations

  • www.androidpolice.com: “Halliday claims the battery will provide 12-hours 'all-day use' on a single charge. In my experience, this is incredibly optimistic, and likely only applies if you only see a few notifications during that time and do absolutely nothing else.”

What would change this

  • Independent tests under various real-world usage scenarios to verify the battery life claim

    The Halliday website did claim a 12-hour battery life (supported by [320d6215-2177-462a-b947-4bf28e7e6f75]), but an independent review found the actual battery life to be significantly less. This contradicts the 12-hour claim, making the overall level of support for the claim 'partially_contradicted'. The discrepancy between the claimed and observed battery life also fits with the constraint pack's note on how lab conditions can differ from real-world use [2.3 电池能量密度对续航宣称的约束].
