Battery drain

Jose Luis

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.

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

Soft Reset -> Same Problem.
Backlight is off 🥺

@Ollipolli what is the definition of “extreme”?

Ollipolli

@surfboomerang 1-2% per hour. Without GPS

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

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.

@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

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

You SV owners are suffering from success in the battery recalibration

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!

Umer Javed

Thanks, @Dimitrios-Kanellopoulos

So, the previous instructions were not needed?

Ollipolli

Thx @Dimitrios-Kanellopoulos

SuperFlo75

@Dimitrios-Kanellopoulos Thanks for explaining

Dimitrios Kanellopoulos

@Umer-Javed well needed no , but if you want to get rid of your head playing games to you yes.

I personally never bother about battery calibration and allow the usage of the watch, phone etc to happen naturaly

So, I haven’t worn my Vertical for a day and a night and apparently it lost 40% of battery. I made sure to deactivate HR, sleep and alarms. What the heck.

My S99P survives being outside my phone’s range just fine, so…

Something similar what happened these days. Timeline for experts

Watch charged on the 17th (eventual daily use, almost always in drawer with HR sensor up to avoid false reading)

training day 18/06- 2:30
long break>>>
training day 3/07- 1:25 (I start with 63% battery and end with 60 which seems great to me. Only 3%)
Watch 2 days in the drawer.
training day 5/07- 2:25 (I start with 33% battery which means a sudden drain of 27% in 48 hours without hardly using the watch) Training comes with another surprise of 10% in 2 hours and a half. I end up with 23%.
in the last 24 hours it has drained another 12% without any use and now at 11%

I don’t want to get mad about an issue, but this was testing my trust in Suunto.
I await clues and clarifications dear friends.

I would restart the watch, charge it completely and observe the behavior.
if it happens again: magic logs would help

@freeheeler
Thanks, that’s the first thing I’m going to do.
