Software Update 2.48.16 (2025 November Rain release)
-
@Kraisun-Tunta Thanks! This is helpful!
I guess I’m a little bit obsessed with the battery right now. I still think the drain is too high at some points. First I thought it was a hardware defect. Now I think it’s a software defect. Maybe less running with HR-belt will help
Next cycle I’m going to throw the battery status off the watch. Do’nt wanna know till I’m at 20%

Since Tuesday, 18/11/2025, I have switched back to Race 2 with the latest software.
In terms of activities, I did: 5 hours of outdoor sports in performance mode (without AOD and with external HR) + 45 minutes indoors without GPS. Starting from a 100% charge.
I am currently at 75% battery (i.e. just under 8% battery/day consumed with these activities). This is better than the Vertical 1, without a doubt. I find the battery life on the Race 2 quite impressive. And for me, it is very close to the specs.
In terms of daily settings: no notifications, 24/7 HR, sleep tracking + VFC, low brightness, turn to wake up.
Fun fact: at night, the Race 2 consumes 1% of battery. The Vertical consumes 3/4%. While the settings are strictly the same, there is one slight difference: the AMOLED is always off when the MIP works once a minute to update the time.

if there is no movemement (at night), the MIP is going quickly in power save mode (black).

@Horizontal_2 I might say Suunto’s battery calculation and power management could use some… “character development” —
but I enjoy my current unblocked lifestyle
Let’s just put it this way:
If battery management were an Olympic sport, Suunto wouldn’t be last…
but it definitely wouldn’t be giving the gold medal speech either. -

Obsessing over 1–5% variance is chasing noise, not performance.
Use the watch. Train. Sleep. Enjoy.
I appreciate the above discussion on battery tech and completely agree with @Kraisun-Tunta that obsessing over small fluctuations in percentages is meaningless. However, some of us are still experiencing significant battery draws that cannot be explaining by small variations in battery algorithms.
Last night, my 9PP went from 72% to 59% over the course of ~8 hours of sleep. Typically I’ll see a drain of 2-3% overnight. This was not the result of a “false 100%” reading after a charge, but more likely caused by unwarranted background activity.
If bad battery calculations were the cause, then wouldn’t we also see periods of surprising battery stability or non-draining events? I have yet to observe this.

@Kramble I exercise everyday so that really isn’t possible. I often wear 2 watches but most of my testing is for Suunto releases.

@pavel.samokha Just tried to use user-defined pace zones with my Race 2 (SW version 2.48.16). I found that as soon as I change the predefined zone limits in ‘Settings’ > ‘Training’ > ‘Intensity zones’ > ‘Advanced zones’ > ‘Running’ > ‘Pace zones’, I cannot select pace zones for trainings anymore.
After changing the zone limits, the possible selections in the ‘Running’ > ‘Exercise options’ > ‘Intensity zones’ menu do not include the ‘Pace zones’ item anymore.
A soft reset of the watch resets the pace zones to the default values (which unfortunately are much too fast for me yet) and re-enables the ‘Pace zones’ menu entry in the ‘Running’ > ‘Exercise options’ > ‘Intensity zones’ menu.
This means that for now, I can only remember my pace zone limits and look at the watch often…!?

I thought the issue had been resolved following the latest SV2 update, but after 10 days of use and very little activity, I notice that I am already at 9% battery, which is not in line with what SUUNTO had announced. I think I will end up sending the watch back to customer service.
-
@Frederick-Rochette I’m in this game as well. My SV battery has dropped from 98 to as low as 38% in 4 days only. I have not used it too much, just an hour a day with GPS activity. But one day I also used H10 belt, which I suspect caused this drain.

@pavel.samokha small bug with the morning report. Despite the existence of the “x” on the right hand side, a few of the different sceoll positions don’t allow you to actually exit the report with a click of the middle button.
