Suunto 7: Love and Hate

@Luís-Pinto gali can be more accurate , eg more close lines on come and go under good conditions. Beidou did never fail me

@Dimitrios-Kanellopoulos In all different activities? Hiking/running/bike?

Terrestrial corrections are very important for system integrity. It’s what makes diference in american system WAAS for so long. Europe is getting stability with EGNOS (but need more redundancy), and China with SNAS.

@Chan-Wai-Kit Always on screen will eat into your battery life. If you can use powersave tilt. I did a 4h 40 min run today and finished with 32% battery left.

Every have relation with time, sats have atomic clocks with nanoseconds of precision. But there are small delays in transmission for earth=time travel (ionospheric perturb…). Ground stations make that corrections. Time is crucial for accuracy, i.e time/space, time cannot be separated from the three dimensions of space. One coin, two faces, same to determine continuum (Einstein stuff).

Dimitrios Kanellopoulos

@Luís-Pinto yeah.

I use my app typically to see what could perform best. In France and Greece beidou has the most sats, and best signal

Beidou is big

@Dimitrios-Kanellopoulos China likes everything in big! It’s a superpower like US.

@Dimitrios-Kanellopoulos Well, count with me if you need more tracks to Suunto analyze with Nav+Bds! +1PT

@Dimitrios-Kanellopoulos app name please?

@jorgefd78 That is GPSTest on Google Play.

Second test run this evening:
4km jog, follow by 10 min fast/5 min slow x 3 sets, 64% battery left today.
I have used the tilt-screen for jogging and always-on screen for the intervals.
I appreciate the physical buttons which are very solid so I have no problem of doing manual laps by that.
Nevertheless, I have to admit that I missed the interval auto-lap function on my SWHR very much. I think I will stick to my SWHR for intervals before the S7 updates (finger-cross).

@Chan-Wai-Kit Did you start with 100% battery? Played music? Used map?

I went for a 70 minute run yesterday. Admittedly, I wasn’t using music and wasn’t checking my watch often (I had S9 for that), but I think the drop was barely 10% if at that*. In fact, S7 hasn’t left my wrist since 23:00 EST on Saturday, and it’s still has enough juice to last until 19:00 of today. That’s almost two entire days, with 70 minutes run (GPS+OHR+tiny bit of maps at the beginning)

I think Suunto totally nailed the hardware and battery life on this device

Oh, snap! Forgot to mention. My phone was with me, so it is entirely possible S7 was getting assisted GPS from the phone, courtesy of Wear OS “fused GPS” Looks like I’ll have to test again

@NickK Hi Nick.
Yes, I started with 100% battery. Playing music directly from my phone (bluetooth earbud) so I don’t think that should spend the watch battery a lot .
TBH, 64% left is not super bad for a 70 mins run, but it definitely need more optimization. Especially always-on display is important for interval training (to me), the tilt screen function didn’t work perfectly everytime. Sometimes I have to swing my wrist twice to get the display on.
I just surfed around this forum and some folks mentioned that S7 should be considered as 80% smart watch and 20% fitness watch. I totally agree with this statement.

A Former User

@Chan-Wai-Kit Ah, backlight on… Sort of missed that.

This would explain the drop really, even if we factor in the watch was probably using your phone’s GPS and not its own. And I’d imagine if you had run outside, in broad daylight, that backlight would be burning even brighter than otherwise. I think this explains the battery situation quite nicely.

Looks like you hit the jackpot with your watch @NickK … battery life exceeds Suunto specs.

A Former User

@fejker It would have been a bit short of 2 days, which is their spec for normal smartwatch use. But I did a run, so I’m not complaining. Charging even daily is fine by me. Now I only hope Suunto expands their app, or maybe Stryd ports their WatchOS goodness over to Suunto.

What I really hate is autolap in running mode after each km. When I look at the watch during the running usually there is summary of previous km. I have to wait about 5 sec to see real data. Realy annoying
