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

@Dimitrios-Kanellopoulos
Thank you for your reply and for taking the time to look into this.
From what I understand, it seems that Suunto hasn’t yet identified the exact cause of the increased battery drain, and that’s a bit concerning.
As we can see, quite a few users are reporting the same issue, which appears to have started after the last two firmware updates.
In my case, I started noticing the faster battery drain since June, and I can confirm this with all my recorded charging cycles.
I also tried the suggested solutions, including unpairing all Bluetooth devices, but unfortunately it didn’t make any difference.
I really hope this can be investigated further and that a solution can be found as soon as possible.
Thanks again for your time and support. -
Alright. Time for logs
Press send logs via the Suunto app and send me a message here with the email used for the Suunto app account. Try to send the logs at a relevant time if this is applicable.

Do you need some test without the mobile app connection?
Because I don’t use any Bluetooth gear but I do have battery drain and I just have my mobile connected with Bluetooth.Ambit 3 peak saphir

Suunto Vertical 1:
Yesterday morning battery level was at 10%. I plugged it in, and the charging message/symbol appeared. After about half an hour, I checked, and of course, that crappy charger had failed again. Still at 10%. I plugged it in again, and only managed to charge it to 20%.
This morning, the battery level is at 7%. -
@Stefan-Kersting I started this thread for footpod / Stryd issues https://forum.suunto.com/post/176560
maybe you can post your findings there too
I do not see the same issue you have but definitely something broke recently
-
@Kramble can also be sure keep me posted

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
