Battery drain after update 2.44.46 (2025 Q3) on Vertical Watch

thanasis

I think the sensitivity of the backlight has changed . I believe the watch has somehow become more sensitive in turning the backlight on

Ars Vitae

@thanasis What do you mean exactly? In what sense sensitive?

thanasis

@Ars-Vitae it’s easier to be turned on . I believe (as far as I can tell with one device ) that the backlight is turning on more times that it used to

Yesterday I used my polar h10 chest strap but the h10 was attached to the belt with at just one point, not at to. I do this usually to avoid that the watch and the belt try to connect via Bluetooth to avoid battery drain in my chest strap. But now my watch really often did a “beep” sound without showing something on the watch. After beeing very annoyed I set my watch into flight mode and there was no more beeping. So I think there’s an Bluetooth issue. Now I have disconnected the chest strap and set the watch in flight mode all the time. Will see if this affects battery drain.

@Dimitrios-Kanellopoulos All right, I charged med watch sunday 12.10. 100 % at 19.00. Have 24/7 OHR and had the watch in flight mode all the time. Monday 13.10. 99 % left. That means 1 % battery drain in 16 hours vs. 12 % battery drain a day with blutooth connection on. See my previous post about the behaviour of the HR belt. I think the hotfix has to handle that in order to stopp the battery drain after tha last update.

@Stefan-Kersting I have something interesting
I’ve tried the same approach with Flight mode - watch is draining as before and syncing (or trying to sync to be more precise) despite flight mode on. I don’t know how this is even possible.

Stefan Kersting

@Belial how is this even possible?

@Stefan-Kersting @Belial I think it was discussed somewhere recently, but I cannot find it. But… if you turn off airplane mode via control panel, then all the connections remain on. But if you do it via Settings - Connectivity - Airplane mode, then it turns everything off. I don’t know if it’s a bug or working as designed.

Dimitrios Kanellopoulos

@Belial yes please validate its turned on

I’m sure the switch was active (in control panel).

Now I’ve checked, it’s still on and watch is syncing, with connection icon displayed on watchface

Surely a bug in the watch firmware. In Control panel it simply doesn’t work despite showing the switch as enabled.

Well then disable it in Control panel, then go to Settings > Connectivity > Airplane mode and enable it there. Double check that it can not connect to phone, and then monitor power consumption.

I’ve tried turning aeroplane mode on mine in the settings that did not stop the battery drain.

I’m also trying to test leaving the watch in airplane mode, but I don’t see any real improvement — maybe about 1% less battery drain per day, but it still loses around 8% daily.
Please, Suunto, do something about this… it’s really starting to get annoying.

thanasis

putting the watch into energy saving mode works like a charm . So it’s obviously some process (?) that is consuming the battery

Jacobus

@Stefan-Kersting I used to do this in the past, attaching it to a single button, but it would then try to connect, so I’ve since removed it entirely.
This has nothing to do with the latest update.

Stefan Kersting

After almost exactly 72 hours I have left 91 % and to hours of gps activity included the watch used 9 % energy. In my opinion there s something wrong with the Bluetooth WiFi connection. Airplane mode always on

For reference…
I’m not suffering from the battery drain and have these connectivity settings configured:

Airplane mode: off
Paired devices: Mobile app
Wireless network: On/Auto
Discovery: Off

@surfboomerang Can you be more precise? OHR 24 ? sleep tracking? daily battery consumption without activities ?
Thanks

surfboomerang

@Kramble
24/7 OHR: Off
Sleep tracking: Off
Notifications: On
Daily consumption: 2-3% (with almost no solar power)

@surfboomerang If you turn everything off and use it like a Casio watch from the 1990s, it’s no wonder that the battery drain problem doesn’t occur
