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

[Dušan Ković]

It would be really nice of suunto to give us bug-fix FW update soon, so we don’t have to wait for another quarter update

Mine has been doing this for a long time before the last update prolly 6-12 months ago it started draining like this.

@gone-troppo My Vertical had a similar problem a while ago, but it was fixed with an update or bug fix. I don’t remember.
My watch wasn’t updated to the latest firmware as soon as I read about the battery issue.

I charged my watch on 30.8 and today I have still 47% of battery left. HR, HRV and sleep tracking ON 24/7. 6,5 hours of running and walking with best GPS and H10 as HR sensor for 4 hours of that time. No battery calibration after last FW update. Batterylife is the same as the day I bought mine two years ago.

@Jugger Might be related to the manufacturer of the belt.
The H10 is off if not connected to the belt. With Garmin there’s no real “off” as far as I know.

[Jugger]

@lessthanmore Could be that but overall battery lasts anyway over two weeks. Other users reports 10% per day consumption even without exercise.

Also I’ve never had any problems with new FWs. Is this only effecting people who had dataloss after last update?

[gone troppo]

It’s not to do with the H10 as I only use the H10 and have the 10-12% drain per day

[gone troppo]

Further update I can confirm that disconnecting paired device (hr Monitor) did not help battery life still going down at same rate. There must be other potential causes of this that are unknown

@surfboomerang 2-3% - that’s too much without activities.

[Audaxjoe]

@gone-troppo I had data loss (first time with FW upgrade) battery consumption has not deteriorated.

@Ars-Vitae
Too much for a whole day ?

[surfboomerang]

@Ars-Vitae With notifications on an no power saving… I think it’s a good score.
The drain rate is the same as before the firmware update.

[Ars Vitae]

@sartoric Without notifications, wrist HR off and no workouts mine is around 1-1.5% per day. And so it has been for two years.

[Ars Vitae]

@surfboomerang I’ve never checked, I don’t use notifications. So you’re probably right, it should be a good score.

I’m on my second discharge/charge cycle now post firmware upgrade and it seems like the battery life is returning to previous. Also interestingly yesterday I gained back 1% of battery wing outside most of the day in the sun.
