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

[Kramble]

I can confirm battery drain even after last hot fix update.

[Stefan Kersting]

@Kramble I can confirm the same

[OutdoorMan]

This affects also other watches, not only Vertical.

[Kramble]

@OutdoorMan Pfffffffff…

[fedequei]

@Kramble I confirm same for me! incredible…

For me, on a Race 1, the battery drain actually seems quite a bit worse after the update. “For what it’s worth”.

[Charles]

Same problem for me. battery drains à around 1% an hour during daytime, 0.5% per hour during the night.

I’m pretty unlucky since I already had a sync problem last year with a new update.

[Stefan Kersting]

support recommended a hard reset. Anybody done that?

[OutdoorMan]

@Stefan-Kersting got same feedback and not going to do that.

[Stefan Kersting]

@OutdoorMan what is the problem with a hard reset? Never don it…

[fedequei]

This is the situation after the last 100% charge on September 17.
On September 25 I installed the update, and in the following days I didn’t do any sports due to illness.
The battery consumption still seems very high to me, as I was used to much longer battery life until June

[Charles]

@OutdoorMan Well you would lose all your recorded data without any garantee that the reset will fix the problem

[OutdoorMan]

@Stefan-Kersting basically a factory reset = all data gone, I believe you’ll need to calibrate your HRV for two weeks and such things. So nope.

[Stefan Kersting]

@OutdoorMan ok, that is not an option

It won’t work anyway didnt for me

[Kramble]

Without activities, OHR 24, I have 6 % per day , it was 3 % before the update. I don’t use any belt or other Bluetooth…

Anybody knows if Suunto is aware of this battery drain issue ?

[Sergey Balbir]

There is definitely a problem with the algorithm that estimates the battery level. The watch needs to be reset from time to time to recalibrate. The reset itself is not safe and can cause the watch to stuck in a “recovery loop”.
I don’t think it is relevant to some specific version update (but might be related to the update process or even to a simple on/off ) and this also seems to happen on all the Suunto models.
This situation is quite disappointing for me because one of the major pros to go with Suunto was the promised battery life

[thanasis]

@Sergey-Balbir I think there is an issue lately though. I get significantly higher consumption per day despite trying to deplete the the battery and recalibrate . I even started thinking it may have been some change in the throttling of the the cpu to support the ui smoothness . I don’t believe that it was on purpose to promote the newer generation of the watches as I have read on some other posts in social media

If you don’t want to think, why would not not want to write it?
No specific to you only, but could one really think that (thus write it) “bugs” are introduced on purpose. Come on…
