Battery drain

[BrunoH]

I finally managed to calibrate the SV battery; drain it to zero, recharge it to 100% and then did a soft boot. Now the solar charge won’t do anything. The charging circle won’t lit all the way, only the lightning icon in the center lights up. The bars remain in the minimum as well. I guess that’s how it should be, right? Turning off the solar charge and all indicators when the battery is full?

@BrunoH I just charged my watch for the first time since Suunto started shipping the watches. (Holy sh*t Suunto. Impressive! )

My watch only charged to 99%, even after a soft reset. I tested the solar charge icon and it lit not only the flash icon but also the first ring. The sun is very low now so that could also be the case.

When first time i did battery calibration my battery can reach 100%.
Yesterday is my second time charge the battery. I waited for 45 mins but still showing 99% then i stop charging it. So stop at 99% i guess it’s normal to prevent overcharge?

My vertical is currently at 32%, I charged it the first of June if I remember correctly and used the GPS a lot. I think tomorrow will be a good day to charge it (also need to download some maps before the holidays).

Charged mine 13 days ago, achieved 22 hours of activities with GPS to best, HR and sleep tracking H24 ON. Still 35% battery remaining. So I have the same excellent performances I had with the first cycle of charge : => around 20% battery for daily use (1,5%/day). That makes around 45% battery used for those 22hours of activites.

Didn’t notice any calibration impact

This is really funny: After coming home from a 25k-run yesterday (starting with 7%, ending with 4%), the Vertical went in a power saving mode at 2% in the evening.

Waking up this morning i had 1% left.

At lunch time i walked 3 kilometers and now i’ve got 0% since 2,5 hours. This watch will not capitulate!

Is for the SV also 50% still the minimum charge?

@Tieutieu only train with chest strap not with OHR. I got 55h of Training with 1 charge

After two weeks with SV and being worried about battery drain, I think I’ve found my battery destroyer.
Notifications (Teams, emails, whatsapp, calls…).

When deactivating them, I see that the battery consumes according to what Suunto promises.

It will not be possible to review this to improve it.

[Ollipolli]

Before the Update, battery consumption was ok. After the Update, the Akku Drain was extreme.

Soft Reset -> Same Problem.
Backlight is off 🥺

[surfboomerang]

@Ollipolli what is the definition of “extreme”?

[Ollipolli]

@surfboomerang 1-2% per hour. Without GPS

[A Former User]

@Ollipolli I’d contact support. Maybe your watch needs to be replaced.

@Ollipolli

If you haven’t already, you may need to recalibrate the battery. Drain it all the way to 0%, then charge all the way back to 100%

We noted this problem in the 9PP after the update also.

I never heard that it is necessary to calibrate the battery… last time I have read that it is not good for a lithium accu to drain to zero… I‘m really confused!!!

[Umer Javed]

@SuperFlo75 I completely agree with you. I’ve never “had” to recalibrate the battery, or get such battery drain behavior on any of my tech after an update. This was suggested to me in the 9PP thread and appears to have solved the same issue I was having.

[SuperFlo75]

@Umer-Javed this solution was suggested here several times, too. But I think if it is important it should be suggested in the User manual of the watch, too? And btw it is not easy to go to zero with a SV… I was at 19% after more than 5 weeks of using… and I charged because I wanted to load new maps…

I trust the suggestion because it comes from people in contact with Suunto, beyond that I agree it’s very atypical. I can’t comment on this further than that.

My trick to drain the 9PP was to

1. start a GPS activity indoors
2. with an S+ app that does a lot of calculations (e.g. fat burner)
3. display turned to light mode
4. brightness full
5. backlight on
6. stay on compass screen
7. autolap every few seconds, so the vibration and sound would keep repeating
   …

You SV owners are suffering from success in the battery recalibration

[Dimitrios Kanellopoulos]

Let me explain a few things about battery calibration.

First of all this happens after some health markers on the system are reset. Usually after an update. It happens to Macs phones etc.

The effect is that usually you see the higher battery percentages dropping faster than expected and the lower ones (ie around 30-20%) dropping very slow. For example you might see 100-90% drop in 1 day (not expected) and stuck at 30% for a whole day.

This gets fixed automatically as the battery watchdog calibrates it self during the normal usage.

Draining the battery by various ways ain’t good. And most probably it’s not needed as the watch will last / should last as expected.

My suggestion is.

• in case you have a high drop in battery just do a reboot of the device to rule out any other issue.
• once in 3 months let’s the watch charge on a full circle (0-100) if possible

Enjoy your watch and life.

thanks @Dimitrios-Kanellopoulos for this clarification. makes sense!
