Sleep Tracking
-
Have been using a Fenix 6x Pro Solar (F6) for the last couple of nights. Uses all the same firstbeat algorithims as S7 except for the quality and then the calc of your body resources recovery - they are using their own info based on their years of data.
F6 & S7 are pretty much matching and getting very similar readings, however the quality on the F6 is much higher and seems to be far more realistic, especially when I add in respiration, Ox and movements readings which all show my quality is much higher than the S7 shows. This also ties in more with my CPAP machine and can see the impact on my quality of sleep matching CPAP apnea score against respiration and Ox changes - which are all tying in and accurately reflecting in how I feel and what I am getting as quality.Certainly suggests that firstbeat need to review their quality calc.
-
@mjposner we have the same sleep respiration rate.
-
@jamie-bg I have F6X too. Usually get the same quality, 80% and higher from either F6X or S7. In fact they are roughly in agreement, on sleep times, phases, and quality.
-
@nickk they should be as they are both using the latest firstbeat sleep metrics, only difference is the quality calc, which Garmin is using their own.
-
@jamie-bg Not sure Garmin has much left of their own. The homegrown sleep tracking was always abysmal to say the least. My understanding is that most of their product line is now using Firstbeat algos or is being converted to use them.
Also, there’s a difference in sleep quality implementation between Fenix 6 line and newer Venu2, which not only gives you the score but also explains which aspects of your sleep contributed to it. The big number remains the same, but now comes with some context.
-
@nickk F6 does give some context - main result of widget - Short but continous sleep.
Final widget screen - full comment: You sleep less than recommended but continously, which helps you have more energy and be more alert - bit of Duhhhhh…
But yes would be helpful to see how it breaks down the quality score. -
@jamie-bg No, that’s just a short summary. Venu2 has literally entire screen explaining the score, breaking it into duration, REM and deep phases duration, restfulness, and what not.
I’m sure one of the next updates will add this to F6 too. Garmin’s been pushed hard by COROS to play nice with older watches.

@mjposner Have you noticed how many people start their sentences with “So” these days??
It will haunt you now!

I have noticed a peculiarity regarding the sleep tracking of the Suunto 7. One evening my watch ran out of battery and went into the battery saving mode. I put it on the charger and forgot about it. When I was going to bed I realized that I wasn’t wearing my watch and so I took it off the charger, put it on my wrist and fell asleep.
Next morning when I woke up and looked at my watch I noticed that my watch wanted me to input my pin code. I have activated Google Pay with pin code and when I strapped the watch to my wrist the night before I never looked at the screen and did not input the pin code. The result seems to be that the watch never activated the sleep tracking and therefore no sleep data was recorded that night.
Has anybody else experienced anything similar?

@aeroild my understanding of WearOS (not as a developer, just as someone who has used for a few years) is that if a watch goes into battery saver mode, then WearOS itself is shutdown and the device runs using a propriety low power software.
Now, when you charge the watch back up again, WearOS does try to start up, but needs to be unlocked in the same way that a laptop needs to be logged in. This is essentially to allow the OS to fully start up and run apps.
You can try this whenever you want by simply restarting the watch. Once it has cycled and gets to the unlock screen, you will not be able to see the watch face and complications until it has been unlocked. And most of these complications will take a moment to load.
This is not like the watch locking itself after being taken off the wrist, as in that instance the OS is till fully operational.
Think of it like a laptop again. Restart a laptop and you need to fully log in in order to access the OS and to run apps. BUT, you can lock the laptop at any point and apps continue to run in the background.
SO, if you had simply removed the watch from your wrist (for example to shower) and put it back on without unlocking it, then sleep tracking would have taken place. But, because the watch had effectively shut down and you had not yet completed the boot up procedure, it could not run any apps.
I hope this helps

@olymay Yes, this was also my asumption, but I’m not sure it is like that. Reason is that a few days later watch also ran out of battery, I charged it, put in on my wrist, but before I could input the pin code the watch started to receive notifications from my phone. So I guess at least some functions of the watch is fully working even without “logging in”.

I’ve also had that happen, but for me they were old notifications that had already been dealt with on the phone. Because the watch had lost connection to the phone I think something got a little confused and maybe they were trapped in the ether, unable to be cleared by the phone?
I dunno -
@olymay I did a test now, turning on battery saving mode, putting watch on charger, waiting for watch to start, sending a text to my phone to see of the notification would reach the watch and it didn’t. So I guess you are correct!
This then turns out to be a peculiarity related to restarting of a watch secured by a pin code. Until the pin code is entered the watch will not count steps, not receive notifications, not activate sleep tracking etc. In contrast to a watch not secured with a pin code. Good to know!
-
@aeroild - makes sense when you think about it, as the whole point is not to be able to use the watch until it knows its you.
Bit like an android phone in that way - when you reboot it, if there is a pin/sim code you have to enter, it will not boot up until those are entered. If no code, then nothing to stop it booting up. -
@jamie-bg Yes, it makes sense, but for someone who’s been using the watch 1.5 years without a pin code (because Google Pay wasn’t available) and previously has used other Suunto sports watches, this was for me an unexpected new behaviour. I guess I have to see this watch more like a computer or phone than a regular Suunto sports watch.
-
@aeroild - and I think that is one of the biggest issues with Suunto’s marketing around the S7 - not clearly defining what it is, which I understand is difficult, because it is so close to bridging the true fitness watch gap.
