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?

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

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.

I’m also trying to fully discharge the battery because the consumption data keeps getting worse.
I’m attaching a chart from the last recharge, which only shows two hours of recorded activity. I have HR tracking enabled all day, but notifications are turned off.

Based on what you wrote and this table, you should record consumption at around 54%. 12 x 4 (normal consumption without notifications and HR - max. 2% + 2% wrist HR for 24 hours) and approx. 6% for 2 hours of activity. The consumption should be at around 45% on the last day. This is clearly an issue. In comparison, I have not noticed anything like this on my SV. The consumption is similar to what it was before the update. If more people are experiencing this issue, then history is repeating itself from a year ago. I hope for all of you that Suunto is aware of the problem and will solve it quickly.

I have also noticed excessive battery drain since the last firmware update. I used to have a drain of around 5% per 24 hours without any activity (since the fixes made a few months ago: https://forum.suunto.com/post/158362).
Since the last update, I’m now at over 10% with the same watch settings.
It’s a bit disappointing to have these excessive battery drain issues again.

Mine is similar to yours getting worse, in previous 24 hour it went down 24% and in last 24 hours went down 27% …. Basically every hour it drops 1%

My battery consumption is almost the same as yours. Without any activity, it uses around 6.5% on average. I wear it 24/7, keep sleep tracking and HR on, but notifications are off.
