I watched the announcement yesterday and was very surprised to hear the watch battery life is still so shocking.

Especially considering how useful sleep data is, then I was surprised to see they're only getting sleep scores now.

My dirt cheap Huawei watches have had this for years. It's accurate enough (my own perception based on use). And I get a weeks battery life too (although I don't have the distracting fancy notifications perhaps). It does check blood oxygen levels, heart rate, stress etc.

I truly thought this was a solved problem (looking at headphones battery life, although I might need to check my assumptions here also apply to Airpods).

The watch has sleep data (for example phase durations like rem sleep and apnoe), the health app just doesn’t compute a „score“.

I charge when showering in the morning. 15 minutes is enough for the day + night, half an hour to charge it fully.
