Suunto 7

olymay

I’m very disappointed about the suunto 7 battery.

Dissapointed? It has the best battery of any WearOS device (the TicWatch Pro 3 is a close second in my opinion).

I can get easy over 70 hours of life if not tracking GPS activities. Considering the functionality of the watch, that is absolutely mega!

With 24hr continuous HR that will obviously drop, but it still eclipse any other WearOS device.

Sleep as Android is a notorious battery hog, so I would also expect the Suunto sleep tracking to be less of a drain than this.

And for those worried about when and how to charge it, my solution is top charge when I shower, shave, and brush my teeth in the morning.
With my current levels of activity and with how fast the S7 charges (which is mega fast!) I only need to do this every two days!

The S7 is a battery beast!

what is the max power for charging? 10W?

@olymay I totally agree, except the Sleep as Android part. I use it and the battery consumption is around 2%/ hour

@jantikainen I haven’t used SaA for a while, as it used to eat roughly 50% battery in a 7 hour sleep. So either the app has been updated, or it simoply works better on the S7.

Either way, the lack of proper automatic sleep detection and what I think is a horrible UI are still enough for me to steer clear.

I am really looking forward to comparing the S7 sleep tracking with the Withings Sleep Analyser which is what I currently use.

Been looking at that device. It’s a shame that we are still in a situation where different health device makers don’t really work all that well together. I remember thinking Google Fit was going to be the solution to that problem .

@aleksander-h It’s frighteningly clever in how it works! I have a Simba mattress which has memory foam in it, and the analyser sits underneath this and can detect my heart rate THROUGH the mattress!!! I’ve no idea how it works but it does!!! It is also medically approved to detect sleep apnea (I was worried I had this but this device says otherwise ) as well as detecting snoring patterns.

It’s also nice not to have to wear something on my wrist.

The only downside to it, is that you can’t take it with you. As I am starting to once again plan some trips away later in the year, it will be nice to have a sleep tracker that goes with me

That is the big one for me. Still not sure if I’m going to use the S7 for sleep tracking. When I sleep, I sleep COMPLETELY naked, wrist included .

I did a hike today until the battery completely died and the watch powered off automatically.

After I charged the watch, I check and the activity was saved but some data is missing.

The distance, time, HR and GPS course were saved correctly but details like ascent, descent, steps, calories, TSS, PTE, EPOC are missing.

Also, in the diary of the Suunto app on the watch there is only the total duration and the auto laps.
It tries to load the graphs with the HR and pace but imediatly disappear.

Is this a normal behavior for when the watch shutdown during an activity or it was a bug ?
Just to know for the future to manually save the activity before runs out of battery completely.

@steff I had the same happen earlier this week and can confirm that steps, ascent, etc is not showing in the app.

First few days with Suunto 7. Noticed I left the daily HR monitor running and it’s reading a HR when I’m not wearing it. The Daily Activity window will show the HR fluctuating as it lays on the bed next to me. Anyone else with this issue? Defective?

Harboe

@808hiker did it have sensor face down? If I leave with the glass towards the table, the sensor turns off right away.

Steff

@aeroild that’s a bummer.
Maybe some metrics are calculated and stored only after the activity is manually saved.

From all of those the most important are ascent and descent, especially for hiking.

On all other sports watches I had if the watch powered off during an activity it saved all the metrics until that point…

aeroild

@steff Yeah, it’s a bummer that metrics like ascent and descent aren’t saved or calculated by the app. If you log into http://quantified-self.io or connect a service like www.runalyze.com you will get the ascent and descent also on the auto saved activities.

isazi

@steff I don’t know exactly about the S7, but for other Suunto watches some computed metrics are only saved at the end. So if your watch crashes or turns off, they are not added to the header file of your activity.

@808hiker The watch has a sensor to detect when it is on the wrist or not, the HR should shut off quickly after you take the watch off. Try a soft reset/reboot.

808Hiker

@harboe Yes, the sensor was facing the bed. I’ve never put watches glass down on any surface for fear of scratching the face. But the issue is what the heck is the sensor reading? I took a video of it just casually going from 88-106 bpm while laying there. My initial impression was the watch makes up a heart rate when it can’t find one. Like whatever range it was last in. I’m quite confused by it. I’ll try restarting it as someone else suggested.

olymay

@808hiker This may be a bit of a random question but is the underneath of the watch clean?

Every WearOS watch I have owned (I’ve had a few over the years!) has been able to (very quickl) detect that it is no longer on a wrist and stop the heart rate sensor from activating. This is also part of the security feature in Google Pay that forces the watch to need unlocking if it has been removed.

When I take my Suunto 7 off the HR sensing light stops in under half a second (I haven’t timed it, but it is seriously quick!).

Maybe there is something on the bottom of your watch stopping it from detecting it has been removed? Does the green HR sensing light continue to flash when you aren’t wearing it?

If it is clean and free of anything obstructing the bottom then I would suspect either a software or hardware problem. But either way something is defective.

808Hiker

@brad_olwin It definitely shuts off after removing it from my wrist. As soon as I set it down on a surface, it says “measuring…” for a moment and returns with a HR value. I reset it as suggested, but I’m currently watching it read 139bpm while it’s laying sensor down on the bed. I’ve taken a video of it from reset to reading a pulse without wearing the watch as I can recreate it reliably. It’s bizarre. If anyone wants to try theirs to see if it happens, I’d appreciate it.

Lay watch on fabric surface sensor down.
Select Diary, Daily Activity.
Heart Rate section will say “measuring…”
Without waiting for it to find a “pulse”, go back to the Suunto start activity page with the map at the top.
If you see a HR value next to the heart icon, go back to Daily Activity and it’ll be there too.

I have nearly six hours of HR measurements while I slept in another room.

808Hiker

@olymay Yes, the sensor is clean and I removed that blue plastic protective sticker. No obstructions. I’ve only worn it one day, and that was just around the house to get used to the features. No grime yet. The green light turns off quickly. But I can see it flash back on when I’m setting it down slowly. Usually about an inch away from a surface. Then as it lays on fabric (I haven’t been able to recreate this reliably on a hard surface), the watch starts “measuring…” and ultimately finds a pulse. Would you be willing to try it using yours? I listed the steps on my previous comment. Regardless, thanks for your input.
