100% very much top needed feature in sleep!! Thats the whole point if we are not capturing sleep data including any naps the the entire section is compromised please prioritize this. Think that there are multiple health products that sell only sleep features and its so big come on how come this is not available yet!

The algorithm used in xiaomi mi band tracked automatically when I go to sleep, even for a 20 minute rest in the afternoon perfectly

It would also be nice to be able to have the alarm auto adjust based on what is configured in the sleep schedule in Apple health. Perhaps to make the wake up window automatically start 30 minutes before the Apple sleep schedule alarm.

I have a shortcut that automatically puts my phone into sleep mode when I’m home (geo location or if I’m connected to my home WiFi) and when my phone is plugged in after 10:30pm. This has been working quite reliably for me.

I also have another shortcut that disables sleep mode when my phone is unplugged after 5:30am

If you have an iPhone, you can set how at what time your phone should go to sleep every day and until what time. Then it works automatically by command, is my experience:)
