Battery drain after update 2.44.46 (2025 Q3) on Vertical Watch
-
@jjpaz I actually have an iPhone… so after each activity, do you go to Settings → Connectivity → Paired devices and unpair everything that’s listed?
And do you also perform a soft reset, which in any case resets the daily energy levels to 70% and messes up all the stats? -
@jjpaz I find that a very interesting thought.

@jjpaz said in Battery drain after update 2.44.46 (2025 Q3) on Vertical Watch:
(I’m wearing Race S for sleep tracking).
I think this is pretty important, it seems that HRV tracking takes a toll on the battery, so if you don’t use the Vertical for sleep tracking that could explain why your battery drain is lower than what is obsreved on this thread
-
@fedequei No, I don’t unpair devices, I keep then paired. I power off the BT device (turn off Coospo armband or disconnect H10 sensor in my case) and then I soft reset Vertical watch. With this process SV doesn’t try to connect to BT devices until I start a new activity. If I don’t reset the watch it tries to connect to BT devices even in watchface mode and draining battery.
-
@Elipsus I was wearing SV for sleep tracking several weeks ago and battery drain was around 1-2% by night (5-6% daily) so there wasn’t a huge difference. The big difference is if I don’t reset the watch and keeps trying to connect to the BT devices. In that case my daily battery drain was around 17-20% (with same sw version)
-
@jjpaz I am on Android and I do have battery drain

After unpairing all Bluetooth devices from the watch, including the Suunto app itself (I also forgot the Suunto watch from my iPhone’s Bluetooth list), yesterday at 11:30 a.m. — this morning at 8:00 a.m. I was already down to 17%. So I lost another 10% (a bit more) in 24 hours. There’s clearly another issue that’s not related to Bluetooth.
-
@fedequei Have you restarted your watch after unpairing all Bluetooth devices? (To make sure there is no more Bluetooth related process still running in background)
-
@sebchastang Yes, I did that at 14:00
-
Has anyone tried using a different watch face? I’m wondering if certain faces or complications can be causing the drain with newer firmware versions…
-
@inkognito yes, I’ve changed the watchface for the least-demanding: only time and date. First, it seemed to help a bit (instead of 10-12%/24h consumption was about 6-8%). Now, after the night with DND-on , watch used 8%
I was considering buying Vertical 2 but, to be honest, something wrong is going on with Suunto’s software development -
Has anyone tried standing on one leg screaming this sucks?
-
I think the sensitivity of the backlight has changed . I believe the watch has somehow become more sensitive in turning the backlight on
-
@thanasis What do you mean exactly? In what sense sensitive?
-
@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.
