Battery drain

[kamarasm]

@isazi Sorry, but I’m an observer and really enjoy to playing with this kind of stuffs.
So, I tried to understand what happened here. I got a theory, but need some testing.
All the things started with I modified backlight settings you suggested in a post - to lowering the brightness. But I tried Low option for Raise to wake settings as well. When I realized that it did not worth to change, I sat it back to high. And the mysterious drain started that time.
Last evening - when managed my kids to bath, I got off SV and saw that backlight stay active longer then before. I just tried and it was almost 1 min in every occasions, which is abnormal.
Review all the settings and found that backlight was switched to on.
Which is interesting:

• how it was activated as I didn’t do it?
• if it was active, backlight stay always on, not turned off after 1 min?
  So, I try to repeat the mentioned step above today, to see I can reproduce the issue or not.
  I’ll let you know

@kamarasm even if you have been to settings/general/backlight and set everything « right », there is still a « direct » option to set backlight on that comes over other settings when activated : you find it when you go down from main screen to the menu, just under « do not disturb » and « flashlight ».
(That’s where my wife had accidentally switched backlight on and battery drain was then massive)

Just saw this on SA android

@herlas thanks, I’m going to try

[RightNow]

Is this a bug? Or is this the thing you have to do always?

[freeheeler]

@RightNow
I assume it is a default setting (don’t remember…) and it was frequently asked

[RightNow]

@freeheeler Yes but I wouldn’t call it „unexpected“. Then it would be expected. Is it a bug or expected?

[runomatic]

@freeheeler My new Vertical came with Standby = On, so that should be default.

[jjpaz]

@runomatic Yes, that’s the current default conf.
It will be fixed in the new software, current default mode will be Backlight Off.

Last full charge 20th + (something of sun)
Activity: 4:33h without SuuntoPlus; best GPS + route navigation
Actually: 75% of juice left.

My current configuration:

WATCH MODE
*brightness- medium
*standby- off
*rise to wake- hight

*tones- all off
*vibration- on
*notifications- off

*activity 24/7- on
*sleep tracking- on
*auto no disturb- 23:00-8:00

ACTIVITY
*GPS Accuracy- best
*touch- enabled

@RightNow
in this case I would call it expected.
settings that are not according to the taste of users are not bugs IMO
when standby turns off after some time but it shouldn’t, this would be a bug.

mine is turned off since day one with raise to wake low and still I see relatively high battery consumption. I keep observing

[freeheeler]

@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

[valdis830]

@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.

[freeheeler]

@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.

[Dimitrios Kanellopoulos]

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.

[surfboomerang]

@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.

[isazi]

@surfboomerang I only used it because I needed more maps
