Suunto 2.50.28 hot-fix Q4

The_77

@duffman19 I mean, I was wearing long sleeves, so theoretically they could have been touching the surface, if that’s the case then it’s plausible.

I guess if it happens again I’ll find out!

After latest FW: ~1%/h drain in smartwatch mode (~4d total) 9PP.
• No activities
• GPS perf OK (~37–40h)
• Static WF
• Soft reset → no change
• Flight mode → still ~1%/h

HW seems fine → likely FW idle/deep sleep regression.

I think I’ll roll back FW.

Race S, no issues until the latest hotfix. Now issues with sleep detection. There is also no data on the watch. Should I open a separate thread?

@OutdoorMan no need to open a new thread. It is already known to Suunto, it seems… https://forum.suunto.com/post/185192

@2b2bff I see, thanks. Let’s wait then…

Update – S9PP idle drain

Observed ~1%/h drain in normal mode.
In flight mode: ~0.25–0.5%/h (normal).
BT on (watch) + BT off (phone): normal drain.
Fully connected to iPhone: ~1%/h again.

So it seems related to active BT/App communication, not hardware or general FW idle.

Now testing with background app refresh disabled.

Will report back.

Hi everybody,
Does the North-up option work? I think I tried just after release of version 2.50.26 and it worked, but now on 2.50.28, it doesn’t work, even after a soft reset, any clue?

Just found small bug. The next alarm time in morning report is not right, because it does not reflect alarms set for workdays. I think it only counts with general time.
If I have set alarms for 6:00 and 10:00 on workdays and morning report shows up on saturday at 8:00, it shows next alarm at 10:00 but next alarm will be on monday at 6:00.

S9PP – Idle drain investigation (final update)

I initially observed ~1%/h drain in smartwatch mode after the latest FW.

Testing over the last 24h:
• Flight mode → ~0.25–0.4%/h (normal)
• BT on (watch) + BT off (phone) → normal
• Background App Refresh OFF → normal overnight drain
• Activities (no GPS / short GPS) → within spec
• With Background App Refresh ON → slightly higher idle, but not consistently reproducible 1%/h anymore

Conclusion so far:
• HW is fine (training battery life fully in spec)
• Deep sleep works
• High drain seems related to iOS app communication state
• Not a permanent FW idle regression

For now I’ll keep Background App Refresh disabled and continue monitoring.

regarding the drain/battery management or whatever is related to the indication the watch provides … I am a bit disappointed… after letting the watch deplete and recharged it , I used and for 2 days it consumed like 2% per day - which gave me some smiles… (with oHR and notifications off though) … then I went for a run , using Suunto HR Belt, enabled the notifications and it lost 10% over 1 hour…

it is what it is , but it’s definitely not great

@thanasis if you like you can check battery usage during workout in https://smlanal.szmigiel.design from @łukasz-szmigiel
Export the json form the workout in suunto app and upload it there.

I haven’t checked yet but I guess the permanent sync with the HR Belt or other sensor is using much more battery. I did a MTB Ride this morning only with the OHR and best GPS and it uses about 2,8% / Hour.

Edit:
Uploaded a 10k run from December with Suunto HR Belt, it says 4,04%h. Still have to re-check with latest FW and App version.
