Software Update 2.48.16 (2025 November Rain release)

jjorgemoura

I have a SV1. I installed the update while charging the watch to 100%. It is now at 88%. That’s roughly 4% a day. I wear the watch 24/7, sleep and 24h HR tracking. I’ve done several activities this week (± 6h) however they were all indoor.
I would say I’m not experiencing the battery draining issue, I think! Also, I don’t have the ghost connections issue and didn’t lose the custom HR zones or profiles.

I understand this battery issue, or any issue, in particular if it is hardware (cannot be fixed by a software update), is frustrating for anyone affected.

However, it is very clear that this issue doesn’t affect ALL the users. Thus, we need to try to isolate and identify the conditions that trigger the issue. It’s very difficult for Suunto, or any software development company, to cover and test ALL the possible combinations in which their watches are being used in the real world.

Someone mentioned the issue might be related to the BT connection(s). Maybe this is related to the ghost connections.

Maybe we can try to help by providing some info related to our setup (e.g., how many BT accessories are connected, which ones (brand+type), phone OS/version, notifications enabled, etc). The more information available, the best.

@jjorgemoura most constructive post I have read in days!

@gone-troppo Wow mate, your Vertical sounds like it’s living a harder life than I am.

Mine only has to survive flat park runs and a trip to the supermarket… yours is out there fighting for its life in the rainforest like it’s auditioning for Survivor.

get why battery life is a big deal for you - if my watch dropped 40% in 24 hours in the jungle, I’d start praying to the GPS gods too.

But honestly, with today’s tech and lithium batteries, this kind of behaviour is pretty normal. After about a week, the battery usually slows down its drain and becomes more stable again. Trust me on this one.

Meanwhile, I’m just hoping my watch doesn’t die before I finish my 10K.

I’m sorry but battery life is the key reason I bought my new Vertical 2 and it doesn’t meet the specs (by far) and this is a very bad indication about the future. I have a 5 year old Coros Apex Pro that I’m replacing because I went down from charging every 18 days to charging every 5 days (with a weekly 12-14 hours of GPS). After the latest update to 2.48.6 battery draining remains at some 10% per day and about 2% per hour with GPS. That barely lasted a week. Yesterday I reached 12% so I finally charged to 100% and for good measure did a soft reset too. From 10pm to 5:30am during sleep mode with HRV and without spo2 battery dropped to 96%. That’s worse than before the charge cycle. I’ll continue to monitor with the same settings for the day (AOD, HR 247, notifications on, discovery off, no BT devices connected except the phone app on Android Pixel). I know that sometimes off the charger the first few percent can drop quickly but this isn’t a promising beginning.

Battery los of 40% a day ? Something Not correct guys… Send the watch to suunto and get a new one … Just Like that good luck

SODIUM

My R2 battery drains 8-10% per day. I use GPS for 40 minutes per day and sleep with it. After 4 days, the battery is at 65%.

dani_degi

@SODIUM i loos 10% a day included 1h gps RUN and Night sleep tracking inkl HRV THIS IS OK i think

@cheetah694 i fully agree with you - recovery is super important in general training. I was saying that 1 number will never tell you how your recovery is going. Yes Suunto will try to calculate a guestimate number based on training intensity and lenght, but it is just a guestimate. Don’t get me wrong, I would like that Suunto would fix a bug where it gives 2000+ h of recovery, but that number should not impact your training a bit.

Is that movement detected do you want to resume activity a new feature of this update ?![alt text](image url)

Pups my wife told me that it’s an old feature sorry

I wish this could be turned off. Or at least if this pops and you press “no”… it would resume the pause time (it wount come back anymore…)

@Gideon-Kaempfer I can now say with confidence that even after a power cycle and detailed tracking of my remaining battery over the past 36 hours since the recharge, my Vertical 2 running 2.48.16 continues to drain battery just like before the update: Roughly 1% every two hours without activities and about 2% every hour with GPS. This is with AOD on, 247 HRM, sleep tracking without spo2, brightness low and even with raise to wake set to display only.
That’s about 10 days without activities vs what is advertised as 20 days. I expect Suunto to fix this but I’m very skeptical after reading the disappointment others with more experience with Suunto have expressed.

I got phantom a phantom sensor (which is a Polar Verity Sense I believe) with this update. I can not delete it. When it is selected the menu jumps back to the sensor list. I was able to add the Verity Sense again and the watch uses it. Is there any solution to this or just wait for the next update?

@Gideon-Kaempfer Mine seems to be fine right now. In just about 24 h I went from 99% to 94%. Tomorrow I’ll to run with my HR-belt. That could’ve caused my drain.

Gideon Kaempfer

@Horizontal_2 I don’t have any BT devices connected except for the app running on Android (Pixel 8). May I ask what kind of phone you are using?

Horizontal_2

@Gideon-Kaempfer Ah wait! I have with AOD on about 9 %/day! Or do you mean in sports mode? I use a samsung A53, I think

Francesco Pagano

Is anyone else experiencing lag? If I navigate up, right or down after waking the watch from stand-by, there’s some delay and instead of ending up on the first option on the menu (top or bottom), I may scroll 2 or 3. Before this update the screen was perfectly responsive.

Gideon Kaempfer

@Horizontal_2 I meant without (!) activity. Indeed 9% could be correct if you use DND and the display is dark during sleep (which I do and the 1% per two hours goes down to about 1% per 4 hours (during the second night I tested). So you are also on Android. I wonder if anyone with an iPhone has better battery experience.

The Lost Alien

@Gideon-Kaempfer same here with my Suunto Race 1. Battery drain incredibly fast. My hr arm band disconnect at every pause while biking and I have to restart it at each pause. I finished by downgrading to version 2.43.12. Most stable and bug free. Waiting for the coming update and hope for better fixes.

For reference my battery report:

100% on 11/12 at 8:10 AM to 76% on 11/15 at 5:10PM
≈ 81 hours total 24% used

Average battery drain
24% / 81 hours ≈ 0.3% per hour

Total workout time during that period 10.5 hours 1/2 of it with gps
Wake to raise
Lowest brightness
24/7 plus sleep tracking with oxygen
Wearing all day and night
Suunto HR sensor paired

I don’t recognize any battery fix unfortunately
Frankly, my Peak pro 9 never kept more than 7 days. I have been using it for 1.5 years. 24/7 tracking is on, Raise to wake off.
The last year the battery holds 3-4 days and no more.
Usually, the first 24 hours it looks promising with ~14% usage, but then the depleting growth to 20% -> 30% a day.
The main reason to choose Suunto was it’s battery life for which I was ready to compromise the MIP display. Comparing my choice to any known brand with AMOLED display makes me feel uncomfortable.
