Battery, always-wear, and the Friend scars people bring to Luna calls

What people are really asking

On reservation calls, “how long does the battery last?” often means “will I hate wearing this by week two?” Some callers already tried Friend or another always-on necklace and left with scars: heat, charge anxiety, social weirdness, or a product that talked when they did not want it to.

What Luna is designed to be

Luna is a small pendant you wear through the day. It is meant to stay on you, not live in a case. Charge happens in the starlight box that comes with the reservation path.

We will publish measured battery numbers when hardware is locked for Kickstarter. Until then we will not invent hours.

How it signals without a speaker

Luna glows and buzzes. It does not speak from your chest. Samantha’s voice is in your earbud or phone. That is the main difference people notice after a Friend-shaped disappointment: the necklace is a reach, not a second mouth in the room.

Always-wear is a trade

If you only want a desk gadget you plug in for meetings, buy that instead. Luna assumes you will wear it, take it off when you need privacy, and charge it in the box overnight like jewelry with a job.

Honest limit

We have not shipped production batteries to you yet. Spring 2027 is the expected ship window. Judge the product on what you can wear today (Samantha on your phone) and on whether the pendant’s quiet signaling model matches what you want — not on a blog’s guessed milliamp hours.
