Today possibly cadence lock in first half? Not sure but strange change in middle of activity while i walked same speed all the way.[image: 1758175867575-img_0893.png]

@gone-troppo said in Battery drain after update 2.44.46 (2025 Q3) on Vertical Watch: 44% to 4% in last 24 hours wtf is going on? I have tried every possible fix to that this forum and fb groups have recommended and nothing works. Is suunto aware of this issue? Is there a fix coming for it ? My suunto vertical which was so great when it was released is now nothing more than an Apple Watch that needs constant charging. I have been with suunto for many years but this is a disgrace. My old ambit 3 peak doesn’t have these issues. I love the suunto app and how suunto ecosystem is I don’t want to change but this is borderline unusable. Watch drains more than 1% per hour when not even doing anything and every battery sucking setting disabled. What a joke You can stop (throught parameters) and restart the watch. It seems it has solved temporarily the problem… (now 4% in 24h as before). But sure there is something to correct, because before restart i was at more than 12% per 24h. I hope that suunto team is avare of that and it will be solved soon.

Same problem here (Polar H10). No reconnection is possible. Battery needs to be removed, then it works again.

@withManish Out of curiosity, I measured O2 level on watch and device same time, same hand and here are the results. The watch takes quite a long time to measure the O2 level compared to the device. Out of 5 attempts, once it came to 98% otherwise always around 85% and the SPO2 device is 96-98% at 44 meters altitude. [image: 1758182292816-img_2499.jpg][image: 1758182292839-img_2502.jpg] Once I got alerted about keeping my wrist and fingers stable, that is good, but it should prompt before it starts measuring, so the user is careful at first hand. I raised so many concerns about the software glitches and user interface customisation, but not sure about the engineers whether they are here to read and reply or just we are just taking help from each other to find solutions.

With the beta FW in I did 600 yards in the pool and still the stroke detection doesn’t work… everything is detected as free (free, breast, back). Once change I did see was, when there was a change in stroke during a length, the next turn wasn’t detected.

@Pep-Carbonell yes, the values measured by SZ can be correct and can be closer or further away from time to time but it is hard to know when it is accurate and when not. Scientific papers could show that DDFA is correlated with the lactate threshold but even under perfect conditions/set-up on a treadmill, it is hard to detect the correct value. A publication from May 2025 (it’s actually from the scientific partners from Suunto from Tampere University) showed that the DDFA method indeed performs better than the estimations from HFmax. DDFA showed on average a deviation of ±10 BPMs from the actual value in 58 subjects…±10 though is usually bigger than the difference in HR between 10k and Marathon Pace. 10k is normally well above threshold and Marathon well below. At +10 BPM above my threshold I’m almost dead why -10 feels really easy :D. So it works in principle but is it accurate enough? A good race-based estimation will probably be on average a lot closer than ±10 BPM. (Here is the publication of you are interested https://physoc.onlinelibrary.wiley.com/doi/10.14814/phy2.70241) Of note: the accuracy of detecting the aerobic threshold was with ±12 BPMs even worse.

Received feedback from the support team. They tell me that the Peak Pro is no longer manufactured, nor that they have the parts to repair it. Not sure why they talk about parts, as to me, the issue had nothing to do with “mechanics” (but hey I’m not a techncian). Their position is “we can maybe fix it, but a cost that wouldn’t be relevant to you”, so instead, they offer to me a replacement with another device. With an incredible discount of 10€ !!! Quite interstingly, the Peak Pro is one of the models they’re offering in this deal of the century. Yes. The same model that is not manufactured anymore and for which they have no spare parts if there’s an issue. Just bought a new Sports2. But with a “I give these guys one last chance, before I move to G” approach, as I’m pretty pi**ed off, the failure happened after a failed update (according to me, but once again, I’m no Suunto technicain), 2 weeks after the warranty expired, and by the fact that the support is putting me in a position where I have no other option that to buy a new device. Aren’t they clamining they are a sustainable company? “Repairability” is the basis of being sustainable, especially for a device that was first realseased less than 3 years ago. Or is the image they want to give some sort of green-washing. Anyways…

@Danny-Labrana I didn’t know you could do that either so thanks to you for asking the question & thanks to @Mff73 for providing the answer

@Egika Hi, I’m also waiting for Suunto to get moving and expand its range of applications dedicated to kitesurfing!! Today, nothing is offered and there is no way to connect your watch to the surfr application.

Hello, today we noticed this issue on my wifes 5 Peak. Unfortunatelly it has already 2.5 year so it is not under warranty anymore. And she is light user, and not wearing it while washing dishes, showering, sleeping etc. Only around 9hours a day during working days only and then while cycling/hiking but thats few times a month.
