Software Update 2.48.16 (2025 November Rain release)

[Bug] Vertical (gen 1) 2.48.16: black flash when waking via buttons
After updating my Suunto Vertical (gen 1) to 2.48.16 (“November Rain”), waking the watch with any button causes a brief full-black flash.
Repro: idle watchface → press any button → short full-black → target screen.
Expected: smooth wake with no black flash.
Notes: happens on multiple watchfaces; persists after reboot; didn’t occur before 2.48.16. -
@segi_pn same bug here with Race 2 and Vertikal 2
-
@segi_pn Didn’t notice before you mentioned it - but yes, also exists on Race S
-
@segi_pn I do not notice this behavior… but I notice the problem with HR belt connection
and after one day of usage I think battery drain is still too much 
-
@peegee no, the weather in the morning report was just there today
-
@segi_pn yes can confirm for Race 2 as well.
-
@Miguel-Angel-Moreno with the Race I? I have no battery problems with the Race I - charged 6 days ago and am at 35% with AOD, yet only 1-2h of GPS workout due to recovery from recent surgery
Update: just checked lost 2% during normal night (8 hours) with DND on, HR, HRV and sleep tracking on
-
Battery drain still occurring after update. What did they actually do with this update other than say battery drain is fixed??? Fail
-
@Stefan-Kersting so i can confirm for my Race 2:
Night Blood oxygen works
Manual measurement of Blood oxygen works
Morning report showed on second night (i missed first night), looks good.
Battery consumption in last 24h was 6% (comparable to firmware i got with watch). But i had DND for around 8h yesterday. Not sure how that impact battery comsuption.So battery consumption was higher only in first few hours after update. But i will take notes for few more days just to be sure. But for my Race 2 it looks fixed.
-
@Tomas5 yes my battery consumption is also in line with firmware that have no battery drain, only issue I got so far was a quick hr belt disconnect during a run, we’ll see today if unpair repair have solved the issue
-
@segi_pn Tried to reproduce, but I don’t see the full black screen.
I have the outdoor watchface wait until the watch is idle for a minute. After that I press a button, but all that happens is that the backlight comes on and I see the next screen. -
@surfboomerang It doesn’t happen with all watchfaces. Try the K14 marine compass, Summit Seeker or Concentric analog…
-
New improved morning report is missing Fell asleep and Wake up time? Why?
-
After the update, when I set the watch to do not disturb and lock the buttons, the display lights up every time I move my hand🫣 The previous firmware worked correctly. It put the watch to sleep and the display only lit up when I pressed the button on the watch. Now I didn’t even sleep properly, the watch lit up like a Christmas tree🤨

@Josaiplu
my race 2 works good. battery 10% lost in 1 Day incl 1h run gps… and sleep tracking. ist ok ? -
Suunto’s changelog N years later:
“Battery drain problem fixed”Still draining, though
-
@false users posts after any FW update:
- Battery drain
-
The new sleep report is nice, but when I rewatch it from the menu it’s still the old style (sleep phases )
Suunto S
