Also of note: Fall detection is exclusive to the series 4 or above, which seems questionable.
(I would be very surprised if the series 3 and 4 have significantly different accelerometer hardware)
- dantle 7y agoWhy would a different accelerometer surprise you? The entire SiP is different between the Series 3 and Series 4. One source say the accelerometer in S4 has higher dynamic range.

- garmaine 7y agoSeries 4 is very different hardware. I'm not surprised.
- graeme 7y agoThey specifically said in the announcement that it was due to new tech.
- zacwebb 7y ago> which seems questionable Maybe because they added new hardware to enable it...?
- alphakappa 7y agoConsider that to detect falls reliably, you might need an accelerometer with a higher range than that was in the original watch.
- JaRail 7y agoMight also have needed a higher sample rate. For battery life concerns, I can see them implementing some of the fall detection logic in hardware as well. For example, a high shock or shaking could trigger the fall-detection software to wake. Although, with the 60-second period, they probably wake the main processor often enough anyway that hardware detection might not save much power.
