ZSWatch – The Open Source Zephyr Based Smartwatch

Wow, this looks really good! It already seems reasonably close to commercially available options, while still being extremely hackable.

I do wonder what the battery life is. That pretty much makes or breaks it actually being a smart watch rather than a cool toy to hack on.

Hi, creator here did not know it was shared on hacker news until someone sent me an email.

Battery life is one day with screen always on and about two without. I designed it so that it should have a week battery life with screen not always on, but I have some hw bug so there are some current leak causing only two days life. So I use it every day.

Is the HW bug known, or likely known?

Any possibly soft-fixes via firmware?

I have not debugged it much, suspect hw as I tried a few sw things without success. But could be sw fix. Anyway I'll make a new revision, this current one is a bit limiting due to the MCU and one minor hw bug that needs manual rework of the pcbs.

Imagine putting a transflective screen on it, then. Always on and a week of battery life.
