Battery drain

@valdis830
it’s difficult to evaluate battery consumption with mixed usage (activity and watch mode with different settings).
I’ve fully charged on 19th morning when loading new maps and used the watch in activity for 7h with gnss performance and always 2 S+, sometimes with verity sense… I’m at 46% now with quite some sun every now and then.

but it doesn’t tell us anything, does it?

the most serious way to get a feeling for it is checking the battery estimation before a very long activity and go to start screen after this activity again and check if it estimates reasonably with delta of the previous activity duration.

edit: e.g. today’s lunch run of 80min showed estimation 28h before and 27h after the run. it was too short for a valid number, but it didn’t “drain” to e.g. 23h or something like that

@freeheeler
I heard that the solution for the high consumption of having 2 S+ working is on the way.
On the other hand, I think that the most reasonable way to evaluate the real duration of the battery in a mixed cycle is to leave it around 10% to recharge it the next time. The percentage that is actually displayed many times is not real. For example. Since last night I have 75% and it is still there 24 hours later. Zero solar recharge. Hope this is fine tuned in future updates.

@RightNow I think it is unexpected in this case. Otherwise I see no need for Suunto to mention this explicitly in a SA notification.
If not, they can send notifications for 24/7 HR and GPS performance mode as well because those are also battery drainers.

@surfboomerang
unexpected that backlight consumes more battery than expected? or expected that backlight consumes more battery but customers prefer to have default setting to safe battery and no backlight?

surfboomerang

@freeheeler To me it sounds that the standby light consumes more battery than Suunto intended. Although it could be that the battery claims were made with the standby light off and they send out the notification because it is on by default right now.

In our testing we had firmware updates where Standby = on by default and we experienced higher than expected battery drain. The intent is to have Standby = off by default. Turning Standby = on will deplete the battery faster than the published specifications.

Please keep in mind that battery needs a full circle 0-100 to calibrate. Thus you might see faster drops near 50-100 and slower at lower percentages.

@Dimitrios-Kanellopoulos That’s a problem with the SV. It takes ages before it’s totally empty

I still haven’t used the charger since the watch is delivered. And it will take a couple of weeks I guess.

@surfboomerang I only used it because I needed more maps

@surfboomerang You can leave the watch with an activity started and wait 2 days to drain the battery!

during my last activities battery drain was ~5% in one hour. I lost 50% of battery in 10 hours bike ride - custom sport mode, weather + climb sport apps and navigation where I had more than half of the time only black tiles…

Did you checked if backlight is off ??

dombo

@Tieutieu yes, it is off. in standby battery is OK

So this happened today…

Yesterday I went to bed and had still more than 30% of battery left.

I however woke up with 16% battery left, not sure what happened overnight, but I have also had only 51 minutes of sleep recorded. 16% is still enough, so I went out for a bike ride. When I started the activity, the battery prediction showed only 2 hours of activity left - that was strange. I changed the Battery mode from Performance to Endurance, which showed 3 hours - so I went for the bike ride. After 30 minutes the watch turned the power saving mode on, and shortly after that turned itself off.

So yesterday at 22:30 it was 30%+ and today around noon 0%. Standby is OFF. Brightness and Rise to wake on Low. Any idea?

Brad_Olwin

@tomasbartko First, did you check Standby backlight? Second, has the battery cycled from 100% to 0% to calibrate? The percent battery may not be correct, see posts on this.

@Brad_Olwin I have Standby turned off, but I didn’t go through the first cycle. I have read comments about the first cycle, but have never experienced this with previous watches (also from other brands). Is this “Vertical specific”?

@dombo using two S+ apps results in twice the battery consumption

@isazi even if an app just displays the notes or some very simple stuff?

isazi

@Łukasz-Szmigiel seems so to me, I think it needs further optimization

Hi, I want to cycle the battery from 100% to 0%.
Currently it is 20%, is it necessary to completely drain the battery or do I have to charge it before?

Thank you
