Battery drain

[gkaempfer]

@Horizontal_2 I just finished a two week cycle including upgrade mid cycle to the latest hotfix.
I managed to get 14 days with 26.5 hours of GPS (running and cycling) on my Vertical 2.
I’m very happy with that. I used some navigation in runs and almost never used the flashlight. Only OHR without external strap.

[Horizontal_2]

@gkaempfer That’s better than advertised. A 14 days-cycle could be accomplished with 20 hours of GPS.

Is this with the best settings and OHR 24/7 on?

[gkaempfer]

@Horizontal_2 Indeed better than advertised!
AOD OFF
Raise to wake: Display only
247 HRM
Notifications ON
No external BT connections except Android Suunto App
Wireless OFF
BT discovery OFF
Brightness LOW
DND from 22:00-5:40
Sleep tracking on with HRV but without SPO2
Some navigation but not during most of the activities (maybe during some 7 activities of about an hour each - easy navigation).
No use of any SuuntoPlus Apps
NO USE OF FLASHLIGHT

[gkaempfer]

Note that I did run down the battery all the way to 3% before recharging (ran a marathon in the last activity beginning with 8% or so).
It may need to be counted as 13.5 days because I took the watch off the charger at 19:00 and put it on the charger on the 14th day at around noon (so maybe 7 hours before the full 14 days). However, the remaining 3% would have brought me there easily.

And now I am experiencing an extreme battery drain with Race S.

Yesterday while I was at work it entered an extreme power save mode with 3% remaining, but still shut down a couple of hours later. I recharged it to 92% at around 8 pm last night. This morning, 12 hours later, it is already at 53%. No activities in between!

@gkaempfer Thanks. I’m similair. It’s a bizarre result. Congratulations on your watch. Suunto did a great job with yours

I’ve just turned off the SPO2. Can’t imagine that’ll do tricks, but we’ll see. I do use the flashlight. Only a few seconds per day.

[Horizontal_2]

@sky-runner That’s really weird. Does it happen often?

[2b2bff]

My Race S drains possibly a bit quicker, but not by a huge amount. I charged it Monday in the evening and now it is at 74% including about an hour of GPS tracking…

[sky-runner]

@Horizontal_2 It happened once in the past last year and now was the second time. The rapid discharge has stopped once I’ve recorded an activity - a run.

@sky-runner Do you use an HR belt?

[safari]

I can say this clearly; I don’t need any extensive testing, I’ve been using Sunto Vertical Titanium Solar for a year and a half. After the last firmware update, I started carrying my charging cable with me. Besides, my sports activities have decreased due to winter, I only use it daily. Now my charging cycle has dropped to once every 6 days.

@safari I agree 100%, we need a fix for this

[cosme.costa]

@safari I’m using a SVTS, backlight, raise to wake and notifications are off. I’m doing around 4 GPS hors per week plus two hours without GPS and i recharge it evry two and a half weeks, if I shut down 24/7 and sleep tracking I get a week more.
So, 6 days it is not normal and not related to the last firmware. Do you have backlight or raise two wacke activated? Do you get hundreds of notifications per day? Did you tried to perform a softreset?

[sky-runner]

@segi_pn said in Battery drain:

Do you use an HR belt?

Yes, two different external HR sensors connected to the watch - Suunto HR sensor and Coros Armband HR sensor.

And yes, when I had a similar issue in the past it was likely caused by the external HR sensor. But what is interesting and different in this case is that the rapid discharge has happened after the watch battery got fully discharged and the watch turned off, then I charged the batter and didn’t have any activities.

Hi!

Back again

So, this was a wonderful cycle. It was like the Vertical 2 knew I was logging the drain. It was spot on.

Results:

• 100% to 12%
• Almost 14 days.
• 15,5 h of GPS (the first big activity was skiing. The rest was running, sometimes with maps)

This is what I changed since the last time, where the drain was too high:

• No SPO2. I don’t even know how to interpreted the data, so why measure
• No use of SuuntoPlus Apps during activities.

Still want to know what the effect of the H10 will be, but I’m actually pretty happy with the HR measurements from wrist.

[segi_pn]

@Horizontal_2
This is my last cycle. The next day, I downloaded the map without charging.

[Horizontal_2]

@segi_pn Thanks! So, still a sharp discharge at the first ~10%?

Seems overall better than before? Are you statisfied? For how long do you have the Vertical by the way?

@cosme.costa
I’ve done a soft reset a few times. It hasn’t helped much.
My watch is used daily without any activity being activated.
HR tracking and notifications are on. I wear it on my wrist at night.
Wrist wake-up is on, high.
Screen brightness is medium.
Notifications are on.
I manually sync with my phone 2-3 times a day.
The watch face is athletic.
Daily alarm is on and rings every morning.
These are the things that come to mind.
It’s 100% charged on Monday and drops to 47% on Thursday.

@safari Shut down wrist wake-up…In my experience this is a killer, it enables the backlight even during the day so the battery consumption is very high.
Anyway, with your configuration, I would expect this battery drain, nothing too strange.

@safari in your iPhone do you have Settings > General > Background App Refresh for the Suunto app disabled.
I did see more battery drain when this was on.
