Battery drain after update 2.44.46 (2025 Q3) on Vertical Watch
-
This is the situation since the last charging cycle. Please note that on October 8th I removed the heart rate belt sensor pairing from the watch. Losing 17% in 24 hours seems really bad to me, especially considering there are no recorded activities. I sent the logs yesterday, hoping a solution can be found.

For those of you having problems, what phone do you have? Apparently, there’s also an issue with iOS and Bluetooth connections that can cause increased battery drain on these devices…
In my case, Suunto Vertical Ti, 2.44.46 software version (not updated yet), since I soft reset the watch after finishing and uploading my activities, battery consumption is around 5%-6% by day, with around 7-8h GPS time every week and not wearing the watch at night (I’m wearing Race S for sleep tracking).
-
@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.

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.
