Suunto 9 Baro - deteriorating battery life

GingerBeardMan

@Joohlin Someone did suggest running the battery completely flat before charging it after the update but I think its a case of “more features less battery life”. I have been told that the battery life was not because of a big battery but from efficient use of power so I suspect that battery use during activities is unlikely to change but the first beat features will cause faster battery drainage.

@GingerBeardMan Thanks for the answer.
So one should expect to charge every three our four days from now on?

My estimate is that with 24/7 hour battery tracking, standby backlight on, and syncing to SA the watch consumes about 1% of battery per hour, which is less than 5 days total. That isn’t counting any activities.

I did an experiment and got to five days with only a short activitity (without GPS), and still had battery for a sixth day left.

I could imagine it is premature wear on @silentvoyager 's watch

I doubt that. Until recently I was charging my watch only once every two weeks. I see a high consumption like that only when 24/7 monitoring is on and syncing to SA.

And you know what, I turned all features off last night when the watch battery was 51%. This morning after a run with GPS the battery is still 49% which means the background consumption was less than 1% for the entire night.

@silentvoyager
ok so you can at least exclude this.
I’m just draining my battery to recalibrate it amd then I’ll also go off for 24/7 HR again and see how this changes batterylife.

@Joohlin Sorry for the late reply.
Pretty much, unless you disable the 24h tracking.

Hi,
It seems that in the last time (probably after the last update), the battery of my watch (Suunto 9 Baro) drain faster.

100% - 07.04. - 16:20
79% - 08.04. - 16:40
59% - 09.04. - 16:23
41% - 10.04. - 16:38
16% - 11.04. - 17:23
0% - 12.04. - 12:00
(No activity in this period)

I brough this watch in November 2018, and at the beggining the battery leastead almost 7 days (without activities).
From the beggining until now I keep the same settings:

Backlight Automatic
Standby - On
Brightness - 40%
24/7 tracking - On
Sleep tracking On
Notifications On

So if any setting was changed, what is wrong?

Many thanks
Bogdan

@Chindris-Bogdan battery consumption increased slightly after the fall 2019 update that brought body battery and other Firstbeat features.

Bogdan1921

Thank you for answer!
It’s possible maybe to have a better optimization of the battery with the new firstbeat features and maybe with other features that will come?

Best,
Bogdan

@Chindris-Bogdan we’ll see what future brings us. So far I am OK with charging my watch every calendar week, exercising every day.

Of course battery life is never enough for some of us, and if the watch could last for two weeks I probably would want three

4

@isazi

And when it should be 1 week, in reality there are only 4 days and so on…I don’t want two weeks, three or four. It’s just annoying that from seven days now I’m at four.

Cheers

isazi

@Chindris-Bogdan 4 days without any exercise?

Bogdan1921

Yes, in this period it’s impossible to make exercises…

isazi

@Chindris-Bogdan well 4 days without any exercise seems too little. Have you tried a soft reset already?

Bogdan1921

Yes, I’ve tried, but with the same result.

From my older post, to see my settings:

100% - 07.04. - 16:20
79% - 08.04. - 16:40
59% - 09.04. - 16:23
41% - 10.04. - 16:38
16% - 11.04. - 17:23
0% - 12.04. - 12:00
(No activity in this period)

Backlight Automatic
Standby - On
Brightness - 40%
24/7 tracking - On
Sleep tracking On
Notifications On

What is different in your settings?

Thanks

Try standby backlight “off”

Very similar to yours, except standby off and brightness at 30%.
