Suunto 9 Baro quick discharge problem

MiniForklift

I would definitely get in touch with support so you can a resolution.
I had the same issue with a previous S9 of mine, battery was draining really fast. I took it into the store I purchased it from, they sent it away to Suunto NZ to test and they came back saying that they had found a non-repairable issue. I was offered a refund or a straight swap, problem was all sorted within a week

hey guys, does anyone solved the battery drainage without sending the watch back for support? I have my S9B the eats 4% at hour with no HR no SleepTrackin … no nothing! just time -.-‘’
Can I try something out aside from the soft/hard reset?

Buy those cheap usb mAh recorders
Reset Usb recorder to zero mAh
Empty you watch battery until is black
Charge using usb (see note 1)
Record mAh once charge reaches 99%
If your mAh is around 250, you have a good battery but a drain due to water or a bad board,send it to service
If your mAh is way less than 250, you have a bad battery, send it to service

… so maybe … contact support and ask them. Maybe it’s defective and you need to return it.

Too early to draw any conclusion, but I noticed similar behaviour with my S9. Mine is 1.5 years old now and the last couple of weeks I noticed that watch drain battery faster than it did before.

When I bought the watch I could almost do 12-14 days on a single charge with notifications on and a couple of hours of activity recording.
Now I can barely reach 7-8 days on a single charge with the same settings.

Due to a lot of factors and the fact that I didn’t record the draining process, I can’t conclude that it is a bad battery or the use of the watch changed over the last year.

I let it run out of battery now until it switches off and will then do a full recharge. I will monitor the battery use more closely to hope that I can make any conslusions.

I will keep you informed…

@surfboomerang one more reason is FW has changed since you bought the watches.

Vincenzo Ucciero

@surfboomerang I see, you moved from an extra long duration to a ‘normal’ duration… mine is 1 week old and it lasts 1,5 day(s)… makes me loose my senses

@Vincenzo-Ucciero if your S9 lasts only a day, and you are not doing 15 hours of GPS tracking a day, please contact support because your watch must be faulty.

4 Days with 6h of activities (Performance mode).
My watch was brought in November 2018.
At the beggining with sleep tracking, Daily HR 24/7, Notification and backlight (30-40%) it used to leasts almost 7 days.
After one year, I’ve observed that the battery is drainer faster, with the same settings. Maximum 5 days.

@Atlen True. Also Suunto app has changed over time. I don’t know if it communicates more with the watch or syncs different.

Bogdan1921

But official from Suunto there is an answer regarding the battery drain after the last updates?
I don’t know, would be better to know that yes, the battery drain faster or no (then is a watch problem)? They know and are working to improve this? Does it know somebody?

Thanks

@Chindris-Bogdan we all found out that the new Firstbeat metrics computed on the watch (e.g. stress and hrv) consume more battery than before.

Did you measure how much energy does it take to charge battery from 0% to 100%?

I charged my watch to 95% this morning at 7am, I had a 150minute activity at performance gps, heart belt and power pod on, no power saving, hr monitoring on, autolap on, it is now 7pm and my charge is 74% and I consider this normal.

I Have watch since August 2018 and I need approximately 20% per day no activity. Activity requires additional 4-5% per hour of activity at performance gps, hr belt and power pod. I have dnd enabled from 22h to 6am and sleep tracking from 2pm all the way to 9am. My battery has lost about 5% of capacity since it was new. My backlight is set at 30%. I run SA only to sync activity and gps dats, no background syncing. No alarms, no standby backlight, button sound off all vibration on.

I remember having to charge once a week without activity but after FB features last fall, those memories have quickly faded.

If you think there is a problem you should try to narrow it down to the battery or device side.

@lexterm77

Yes, I’ve measured for 3-4 times from 100-0, and I can say that the battery drain is similar with yours.

The test starts from today. I let my watch run all the way to 0% (charging icon) and recharged it to 100% at 15:00 today.
I will keep track of the battery drain every 24 hours and before and after activities. I will post the results once the watch is empty again. (hopefully more then 12 days from now )

@surfboomerang good luck!

Just a short information about an - second time, first time completely registered - incident.
From Monday, 15jun20 2330 hrs until Tuesday 16jun30 1500 hrs my battery dropped from 47% to 0% (till automatic off), without any activity or atypical sync (and I do not use 24hr HR, sleep tracking or notifications). This happened before once, but I did not register the exact hours than.
Really ‘amazing’, as I have no clue why this happened. Usually I have excellent battery life, and everything looks good and stable now again, after I recharged the watch.

surfboomerang

@Shrek3k could it be that Suunto App somehow kept the watch busy? Faulty sync or something?

Shrek3k

@surfboomerang unfortunately not possible, because BT is usually deactivated on my smartphone and only activated temporarily and manually when synchronising activities (or going by car). So, BT has been deactivated all the hours mentioned.

Ok, so the results are in…

TL;DR:
It look like the battery life of my Suunto 9 Baro hasn’t deteriorated over the 1,5 years that I own it.
Even with regular activity it still gives me almost 11 days on a full charge.

Motivation:
I bought my Suunto 9 Baro 1,5 years ago. I never kept a good record of the battery drain, but in my mind I did around 11-13 days on a single charge. Lately I got the feeling that the charge cycle changed from 11-13 days to 7-9 days. Together with this topic on Suunto forum, I decided to keep track of the battery drain to see if my feeling was right and that my watch also suffers from battery deterioration.

Test setup:
The idea was to let the watch run totally out of juice before I would charge it to 100%. After that I would record the battery percentage every 24 hrs from the moment I disconnected the watch from the charger. I also decided to record the start and end battery level of every activity I recorded with the watch so I could distinguish the idle drain (watch mode) from the battery drain during an activity.

Watch settings:
I do use the bluetooth connection and notifications for some apps, but I don’t use 24/7 HR monitoring and sleeptracking.
The table below shows the watch settings that are responsible for the Idle battery drain in the results:

Activity settings:
During my test period I performed 2 types of activity: Running and Windsurfing
The table below shows the profile settings for the two activity types. Those settings are responsible for the Activity Battery drain in the results

Results:
On 17th of June 2020 at 15:00, I removed the watch from the charger after almost 4hrs of charging.
The days after I performed regular activity as the table below shows. The total battery drain over 24 hrs is split into the drain during an activity and the drain without an activity.

Conclusion:
As the results show I almost got 11 days on a single charge.
“Almost”, as I had to recharge the watch before it went completely to 0% because I needed it in an event that day. So I had to derive the last day from the results the days before.

Well…11 days, wasn’t that the bare minimum as when I bought the watch? True.
So had my battery life deteriorate over time? I don’t think so.

Because one thing change significantly the last few months in comparison with 1,5 years ago: The Corona virus.
The virus outbreak caused the closure of all team- and indoor sports in The Netherlands. I replaced a lot of days on which I normally did an indoor sport with running outside (which was still permitted).
This caused more activities with GPS per week thus a higher battery drain. If I see the battery drain for the average Running Activity, I think I would get around 2 days extra on a single charge if a did an indoor sport on some days.

So that brings me back to 13 days on a single charge if I had the same activity pattern as 1,5 years ago. That means I did not notice any battery deterioration over time.
