S9P Accelerometer problems
-
@guy-s Among the problems you listed, I mainly have issues with the 24/7 HR recorded outside activities. I often have entire afternoons at my desk with HR value recorded that are 1.5 or 2 times the actual (85-100 BPM instead of 50-60).
I too suspect that the watch uses data from accelerometer or other sensors to validate/correct HR reading. Hence, as soon as you start moving the HR reading will start skyrocket. I noticed this also while washing my hands: HR goes from 50 to 110.
This particular issue was brought up In another post and i believe someone reported it to Suunto. I don’t know if when it will be fixed.
I too tried soft reset, hard reset and various other solution but didn’t solve any issue.
I called few times tech support here in the US; i was told to send the watch in and Suunto will determine if it needs to be fixed or replaced. Of no defects are found I would be responsible for a diagnosis fee and shipment.
I can’t tell whether is SW of HW related. I hope is something SW that will soon be addressed because certainly this issue makes the wellness data from the watch less meaningful.

The steps will be counted as you state. Even typing.
The accelerometer is fine. We just don’t use any special algo for steps.
Nor for hr it’s used. The only way it’s used it’s to detect if it’s laying on a table

Hi Dimitrios,
Do you know why steps are counted like that? I believe maybe there is a reason .
Thank you -
@andré-faria it’s an accelerometer that counts steps as most of the step counters out there.
On s5 and s3 we have a context engine that plays a little more clever.
The s9P is not designed to count steps as of accuracy there. Unfortunately this is the decision.

Hi @guy-s, I know, it‘s quite long since you wrote your comment. However maybe you read my reply and you can help me?
I have a s9p since a couple of days and I’m experiencing the same problem like you: seems that my steps are 1,8 m long
when Inwalk for 11km, s9p shows me only 6500 steps. For 5km, 3500 steps. Yes, I know, I actually didn‘t adquire my suunto to count steps, however I‘m really not happy with this wrong function. Did you get any solution since you wrote your post? Thank you so much in advance for any information that may help. -

When I first got the S9P my steps were 3M long. After the first firmware update they were reduced to 2M long. After the second firmware update they were 1M.Maybe the new update will be even closer.
The raise to wake got better early on.

I’ve neve paid much attention to steps so glad to know it’s improved!

ahem, they’ve removed RTW during activity…

Dear Guy, thank you so much for replying to my comment. Really appreciated. And the way you did made me laugh
(and made me hope) 
️Thanks! -

I have recently upgraded from Spartan Ultra to the Peak Pro Titanium. I wear the watch every day and I have noticed that my steps have reduced about 20% just by changing watches. For example, today I did a 10.2 km suburban walk and only recorded 8,971 steps during the walk. I am a rogainer and I know my actual is about 1,200 steps per km. I had nothing in my watch hand. I am very happy with the Peak Pro Titanium, but I am disappointed that my step counts have been hammered by a watch change.
