Suunto Software update Q1 (2.53.42)

brettacher

For example, my watch went from ~18% to 0 over night tonight while I was not wearing it. Battery consumption is also higher while normally wearing the watch as well as during activities since the update. I have rebooted the watch several times since the update.

I’ll observe battery consumption a little longer still, to possibly identify a pattern, but as several other users have reported the same here, I think that it would make sense to look into the issue a little bit further from Suunto side (@dimitrios-kanellopoulos).

Hi,

Since updating to 2.53.42 my maps are completely black on my Race 2, all regions (I tested it in Taiwan, Hong Kong and Switzerland). GPS works fine, my position is tracked correctly, and if I load a route it displays as a blue line on the black background, but no map tiles render at all.

Steps I’ve already tried:

Deleted and re-downloaded all map regions from scratch (after the firmware update)
Restarted the watch

This was working fine before. Has anyone else seen this after 2.53.42?

Any help appreciated.

@Hugues-Vinzant
Did you check that map style is not “off” on your watch? You can setup light map/high contrast /off.

@Hugues-Vinzant I have a Race S and had a hike today and played with battery management. Only in performance mode the map was visible, in all other modes black. Perhaps you set a different battery mode?

Is there any more info if the vertical 1 will get any update? What I have read this was not sure.

Tieutieu

@helgonet12 should arrive but no date

helgonet12

@Tieutieu thanks for the answer but the question was if there will be any. Since what I have read this was not clear. But maybe you know for sure

Egika

@helgonet12 as of today it is not sure, what changes can still fit into V1

@Egika thanks for the info

Tieutieu

@helgonet12 not sure, so I guess I should had wrote « may/could arrive » instead of « should »

@dimitrios-kanellopoulos: another problem that I have since updating my Race to 2.53.42:

My watch does not sync regularly anymore, and even if I start the sync manually, it takes very long and activities are not synced completely, i.e. there are activities on the watch that I don’t see in the app. Restarting the watch and/or the app has not solved the problem.

Please fix this a.s.a.p., as this is a really nasty bug.

@brettacher this is not the Suunto support here…
And BTW: what Phone do you use? Which App version?

BTW2: What you are saying: ASAP. But I guess you don’t mean the As Possible part, but rather: immediately.

Are there any updates regarding a software fix for the random reset issue?

At the moment, my watch has been restarting itself multiple times, which is becoming a serious problem. Many users seem to be experiencing similar issues, so I’d like to know if Suunto is currently working on a firmware update to improve system stability and resolve these unexpected reboots.

Any official news or estimated release date for a fix would be greatly appreciated.

Are you using Interval-Guides? Random reboots seem related to the Guides. If it’s your case, can you try using the watch without using Interval guides temporarily? To verify if the watch doesn’t reboot.

@Speed-Man There is also this thread , so the issue is somewhat known and being worked on.

This is a good time to remember people that if you have issues and properly report them, they can be fixed in time for next release.

Option to turn off that dotted ring on a map. Two effects

Declutter the map, especially after adding the icons
No more confusing the ring with a trail

About labels and elevation lines value on maps : I didn’t had focused so much on it because I mostly used my SV1 in situations I could have need it.

But after looking at a friend coros map, and after that going back to my SRs : labels are almost unreadable compare to what coros displays.
It would be great as I mentionned :

to have a display of altitude lines adapted to zoom level
bigger/more readable font

Unless I searched badly, I didn’t saw a lot of feedback about it
Besides that, I much prefer Suunto map rendering.

@aiv4r I dont think its RIP. We could could not deliver the update in a stable way there. And for that we could not stall the updates for the other watches.

Although Suunto’s strategy seems to be not communicating on release dates , can we hope for a Vertical 1 update before the summer? We are impatiently waiting for it!️
Thanks !

I think, that eventually it would have been good for the SV1 owners to skip this update (I hope we will have more updates ) I see some issues with last update that I guess will be solved within next update, where I hope SV1 is included and bug free.

Thanks for the update and kudos to Suunto team!

I experience a bug with resources after the update: they basically stay way too high through days with small rises over night. This does not correlate neither with HRV, sleep duration and HR data, nor with how I actually feel.
Resources metrics worked never perfect for me, but it became a bit more useful from January till now.

Does anybody else experience similar bug?

Hi Alonso,

Yes same for me, I’ve had my new Suunto 9 Peak Pro for around a month - I’m hoping this can be fixed as a bug as it is an existing feature. It just doesn’t respond to daily life really & keep getting 100% sleep quality & 100% resources which I never get with other watches I’ve owned. Min/Max heart rate all set correctly.
