Battery LIfe

JANTIKAINEN

Something very strange is going on with my S7 battery consumption.
It has had a massive battery drain 3 nights in a row.
First night the battery drain was 40%

Second night it was 45%

And last night the battery drain was a whopping 69% (it died at 5 am so I put it on charger)

Took the watch from charger at 8.50 am and 1 hour after the battery is already down 7% and estimated battery life is 11 hours

Any advices on this issue?
besides the ‘native’ apps, I’m using
-Sleep as Android
-Wear Messages (appfour)
-Wear Photos
-Wear Calendar
-Wear Mail
-Ghostracer

I’ve booted both my S7 and my phone.

@JANTIKAINEN can you try to activate “airplane mode” when you go to bed, and see if that changes something?

JANTIKAINEN

@isazi Yes I will test but doesn’t it prevent sending HR information to Sleep as Android?

isazi

@JANTIKAINEN I don’t know either, I’ve got my S7 just two days ago and I’m still at the stage where heart rate data is not recorded at all

@isazi Are on iOS or Android? @JANTIKAINEN I do not have that much depletion from Bluetooth, are there updates happening? I would check app updates. Another possibility is that the phone sleeps and the watch is attempting to connect often. Are there apps that may be attempting to get data from WearOS?

@Brad_Olwin I’m on Android. Today I deleted and then reinstalled fit and now it’s working in the background.

With our interest in battery life on the Suunto 7, I wonder how complicated it would be for Suunto to add e.g. “%-battery used” in the sports activity report?

Same issue here. I turned airplane mode on, selected hiking as the sport. Battery goes from 100% to 28% in 4 hour.

I had the same experience, I also sent my S7 back to Suunto, but they say that the watch has no defects …

@Kai-Liu
Did you use poles during your excursion?
I ask why, for what has been my experience, their use leads to a much greater activation of the screen compared to simple walking or running.

@Saketo-Nemo maybe we should turn off all the gestures for such activity?

@Saketo-Nemo
Yes, this winter with skimo activity and now sometimes with trail Running. I know this problem. I hope Suunto resolve in next upgrade.

Kai Liu

@Saketo-Nemo I do but watch is on my left hand and pole is on my right hand … so it should not matter?
@vr2udt Even if you turn off gestures, it still on when you are in sport mode.

Saketo Nemo

nope. One pole, on the other side of the wristh, i think does not count

I don’t do long activities with the S7, but hiking I should get around 6h at the moment (in recent weeks I have seen 25% consumption for a 1:30 walk in the park).

I ran for 90 min this morning and S7 battery went from 98% to 83%. Pretty good I think. Tilt to wake was on. Trail running activity.

Kai Liu

I factory reset the watch, and on airplane mode a 4.5 hours hike took battery from 90% to 28%, better than before but still not good …

Brad_Olwin

@Kai-Liu I routinely get 6-6.5h trail running and would probably get longer hiking. In March with the firmware you are running my watch went 7h with 18% battery left when I stopped my race. If you turn on Airplane mode and have tilt to wake, do not use maps a lot, some is ok and do not turn screen on all the time you should get 7-8h battery life during exercise. Longer for biking and likely longer for hiking to as HR is usually lower. If you are routinely doing 8h-12h activities this watch is not likely a good choice. However, I know that Suunto will be improving the watch, I just don’t know how long or exactly what improvements will come, and I couldn’t say if I did know.

Egika

@Brad_Olwin battery consumption is depending on actual HR?
Thats interesting. Does it mean the sampling rate of the integrated LEDs is adjusted according to actual measurement?

Thx

Brad_Olwin

@Egika I don’t know and may have misspoken but I do know that biking and walking I get better battery life than trail running.
