it’s really crazy that no one of the suunto-near volunteers or forum members @pavel.samokha @Dimitrios-Kanellopoulos @isazi answers about these bugs…
Have to say again that this is a community forum. If I have something to comment I will, but that’s not my duty. If you have issues you should contact official Suunto support channels
-
@Tomas5 @pavel.samokha I didn’t contact support until now, as I think that this problem is related to the firmware update, it started after the last update. I noticed that problem during the first trail run after the update, I never had this problem before. That’s why I posted this in this thread, and that’s why I mentioned @pavel.samokha because I thought this is the ‚Suunto firmware update Specialist’? There are several guys here who have problems with BT connections… and after following this thread I think that battery drains seems to be correlated with these BT problems?

@SuperFlo75 I have had similar problems with Suunto HR belt.
Started a few firmware updates ago with occassional drops. Then more recently it will connect then drop out altogether. This was happening with the provious firmware and same with current firmware.
Last year I replaced the belt, then the sensor, as the old sensor had stopped working as well. Six months in with the new sensor and the same problem.
I have reverted to my 5 year old Polar H10 belt and sensor with no issues. No problems connecting and no drop outs during a session.
This is looking like a problem on the sensor side for me. I am unlucky to have two sensors fail in 18 months or a BT design issue somewhere?

Those of you having battery issues, it is not everyone. I have my personal V2 running 2.48.16 and battery life is excellent. Use Suunto Smartsensor nearly every day- no drop outs and no BT connection issues.

@Brad_Olwin I can confirm that. I have a V2 here for testing right now. After almost a week of intensive use, I still have 64% battery life. I don’t have any BT problems either.
By the way, I didn’t have any problems with my V1 either.

no problems with Battery Race 2

Could tell me the daily consumption of your V1 without activities but with OHR24/sleep tracking?
Historically it’s between 3 and 4 % (I’ve got my V1 since the release) but since the last updates it’s between 6 and 7% for me and some others. -

Like most people posting here, I don’t assume my issues apply to every watch and every user. However, this doesn’t negate the fact that many of us are still experiencing one of the problems this update was intended to solve.
I think we’re all in agreement that the battery drain issues are somehow related to overactive BT connections. Personally, I suspect it has to do with the implementation of multiple BT sensor connections as this function has never worked properly for me since it was introduced. Perhaps the issue is only affecting those of us with multiple BT HR sensors? Or maybe it is only specific external HR monitors?
My experience
I have two external HR monitors paired to the watch: a Suunto Smart HR Belt and a Polar Verity Sense. If I use one of them for an activity (let’s say the Suunto Smart for a trail run), and the next time I choose that same activity I want to use the other sensor (so another trail run, but with the Polar VS), it is guaranteed that the watch will not connect to that BT HR sensor even though it shows as one of my available paired devices.Even if I go into the activity settings (Exercise options > Sensor data) and select the correct “new” HR and then back out to the activity home screen, it will not stay connected. Currently, the only way to connect the new HR is to select a different activity profile altogether (so, let’s say walking), go into that activity’s settings, select the correct HR, back out of that activity (still doesn’t show the HR sensor is connected, btw), go to the original activity I wanted to start (trail running in this instance), and now the correct HR belt will usually show as properly connected.
I’m guessing this wasn’t Suunto’s intended behavior for having multiple BT connections. And since there are so many issues connecting to different BT sensors when attempting to start an activity, it stands to reason that there are also BT issues outside of activity mode that are causing severe battery draw. For me, I still have phantom vibrations outside of activities suggesting that the watch continues to attempt to connect to my external sensors.
Further, the increased battery drain only occurs sometimes. It is not a constant for me. So some sort of action or behavior is causing it, perhaps related to the dance I have to do to get my external HR sensors to connect.
I obviously don’t know the answer, but that’s why I’m posting my observations here in the hope that it will help lead to a solution.
-
@duffman19 That’s exactly the behavior I’m experiencing.
I alternate between a Polar H10 chest strap and a Coospo armband. Every time I switch sensors, I have to select and connect it in the pre-activity menu, exit the activity, and then re-enter.
And, afterward, especially with the Coospo, the battery drains rapidly, and I get phantom vibrations if I turn the sensor back on.How do I mitigate the high battery consumption? By restarting the watch or putting it in battery-saving mode after completing activities (it’s a bit absurd having to restart the watch 5 or 6 times a week…).
What I’ve also noticed is that the problem seems much more severe on the Vertical than on my Race S; on the Race S, I barely notice this problem or the phantom vibrations…
-
@jjpaz Interesting that you see it more on the Vertical and not the Race S. I have a V1 and 9PP and have observed high drain on both. Perhaps it’s model specific since the V1 and 9PP are more closely related than the Race family?

Today I have to join the “my watch didn’t track my sleep” club. Interestingly it stopped recording HR and resources shortly after I set DND mode yesterday evening and resumed recording after I took it off for a shower in the morning. No sleep tracking, no resources, no heart rate. Very strange this.
About an hour ago I looked at the watch from the side and saw green and red light coming from the HR sensor. But it should only record ox during night?
