Battery drain
-
@t-Dox Oh wow, so all hardware running modern firmware could be affected? Why was I under the impression that this was only about Vertical and Race, huh. I’ve been charging my 9PP about weekly while getting 10-12 h of running done and I’ve been happy with it. Could I / should I be getting more battery time?
9PP since 09-2025.

Is the firmware getting force updated after a while despite your update settings?
Since the update that brought the sync issues this spring, I have been keeping automatic updates off so I have control over my watch and do not risk the chance of bricking it with an update. Since then, after further firmware updates were made available, I have been keeping an eye on this topic and waiting for a good time to update again, after the battery drain issue has been fixed for good and no new issues have been introduced.
This morning I woke up to my watch saying that it had been updated to a new firmware despite automatic updates being off. Not happy about that. Let’s hope I don’t run into any crippling issues, but confidence in Suunto has not been great since the sync issues.

Hi dear, I am not the best person to answer you, maybe Suunto technicians could be more informed and helpful about this. My friends and I have noticed a decrease in battery life following the latest updates, and mainly after the last one. For this reason I opened a thread about it, but it was immediately blocked as a duplicate of this thread… I tried to ask for explanations to the moderator who performed this operation but I did not receive any answers, so I thought of writing my experience in this thread, so that users could deny me or confirm the same problems so that the support is aware of it.
I personally think that, a year ago the battery lasted much longer, because the 24/7 heart rate monitoring initially was not constant but took a measurement per minute. Then following some update (I don’t remember which) suunto increased the frequency of the detections (hr). Then obviously it also depends on how many hours of activity are recorded, especially with GPS. However, I can tell you that until the beginning of 2024, I usually recorded 2-3 hours of indoor activity (without GPS) and two hours of mountain biking (with GPS) and charged the watch every 12-14 days with all the sensors active 24/7. Now it lasts me about 4-5 days, recording a few hours, mainly indoors.

@t-Dox
I also have Suunto 9 PP. I confirm that after the latest updates, battery consumption has increased significantly.
Cured by rebooting. -
@ist-1973 Hi guy, thanks for the testimony. I have done two hard resets, hoping something would be fixed, but without any success… I also thought that, if I were not the only one to think it was a good idea, we could ask for an improvement to be developed: that is, the backup of the settings on the smartphone app: For every problem, the support always recommends a reboot but this is a bit boring, because all the settings are always lost. I think it would be very simple to save the watch settings on a file or Json, on the app and be able to restore the settings after the much-recommended reset. What do you think?

@t-Dox Its a pain in the head (?
) to loose the custom sport modes for me. I wish there can be some backup on the app side for this.Community Manager / Admin @Suunto

)… anyway yes maybe those are the most boring part to reconfigure, I don’t know how complex it is for developers to implement a similar backup, it’s just an idea that came to me after a hard reset -

https://forum.suunto.com/post/84764hi, i hadn’t read the posts you linked. Yes i didn’t mean that my idea was brilliant and original. it’s simply something i thought like probably many other users and that it’s right to share with the support so that it is considered useful and to be developed…

24 hours now with the update. Due to injury I only had a short one mile walk last evening with GPS and external HRM. Only 2% loss in 24 hours.
-
@larrybbaker How do you get that kind of battery life!? I’m down 7 percent in the last 4 hours (with one 30 minute activity)
24/7 HR is on, notifications off
-
@artersull just to clarify - this is not my daily wear watch - so at the moment 24/7 HR is off, no notifications. But - I was seeing more battery drain before the update - even with the watch at rest.
-
So 3 days into the update - only 1hr and 48 min of activity. 2 walks using GPS and external HRM and a 50min gym activity and I am still sitting at 96% battery. We may have a winner here. Again for me this is not a daily wear watch and my daily running is on hold due to injury - but the loss of battery at rest seems WAY improved!
-
@larrybbaker But, yours is a solar. It could be charging while it is not in use. No?
-
@Outdoorsy no - it sits on my desk or nightstand.
-
I’m noticing that my battery is draining quite a bit faster after this update, I noticed it because I haven’t been training as much as normal but it’s gone down more than it usually would. In the last 24 hours it’s dropped 10% with no training
-
Today I ran 25 km / 2h20m and my battery went from 53% to 38%
With the same settings, a few weeks ago I ran 26 km / 2h22m and it went from 56% to 51%

@Francesco-Pagano, same behaviour here: yesterday I rode for about 2[h] and the battery dropped from 35% to 18%.
-
@Matúš @Francesco-Pagano But you are talking about 9PP - if I understand your signature right.
Just because this thread is about the vertical and its not easy too compare these… -
