OHR and body resources hand in hand ?!
-
@binoworld-uk i find the OHR sensor on the S7 is very efficient. I think it runs on the low power coprocessor and uses next to no power.
When the 24/7 HR monitoring was enabled I didn’t notice an appreciable drop in battery life.The screen is by far the biggest drain, so turning off always on display will save battery.
If it helps, I have everything bar AoD turned on (I have power save tilt instead) and get plenty of notifications throughout the day.
If I don’t track any GPS activities I get an average of 48-52 hours of battery life. By far the best of any smartwatch I’ve tried

@антон-шакаль Wouldn’t it continue to work if you use an external HR sensor (like an optical third party sensor or just a chest strap)? I used to sleep with a chest strap and I thought the data was interesting. You can actually see how you’ve gone through sleep cycles. I haven’t seen that from what the Suunto watches record using the optical sensors. Though of course maybe you can see something if you actually record it as a training (and the built-battery lasts that long).

@vinay The S7 does collect data on sleep stages, it just doesn’t display it in the app frustratingly.
If you have the Suunto App linked to Google Fit then you can see the detailed sleep information in there, complete with when you are in each stage of sleep.

@olymay hey thanks for the reply.
I am rather puzzled how you get that sort of battery life. My watch is only 2 months old and it only lasts for 1 day or 1.5 max and that’s with AOD off, raise to wake off, wifi off and only couple of notifications during the day. I have sleep tracking on and OHR on all time. I use Suunto face. I am starting to think mine is probably defective or the conscious to my iPhone isn’t right.
Any idea
-
@binoworld-uk Try using airplane mode for a few days and see how things go. If it lasts longer it could be something related to the bt connection.
trying to guess eh… -
@g-q that’s cool, I am going to try that and see how it goes. I have a feeling it’s the Bluetooth as since my last IOS update, I am having serious issues playing music in my car through Bluetooth. It’s constantly breaking up
-
@binoworld-uk I would echo what @G-Q says and investigate the connection to your phone (especially as you mention you are having other BT issues with it, they may or may not be related).
If the BT connection to the watch is being lost while being worn then it will hunt for a signal reconnect (in the same way a phone will hunt for signal if it loses cellular connection) and this would likely drain the battery.I have my Wi-Fi set to Auto, so that it auto connects to Wi-Fi when on charge and can download maps and any other updates during this time.
I also like using the power saver tilt on the watch face, as this activates the low power watch screen when you tilt it, thus removing the need to wake the watch into high power mode. It might not look quite as pretty, but for a quick glance of the time it’s perfectly suitable.
I don’t know how much battery this could save, I guess it depends on how often you check the time?The only other thing I would check is do you have any third party apps installed? These can sometimes have an impact on battery life.
For example, I had YouTube Music installed and it chewed through battery even when not being used. Spotify was the same. Now that I have neither of them installed (in fact I have no extra apps installed) my battery life is much improved.Suunto 7 Graphite Copper

Plus in the WearOS app on the iPhone in advanced seetings you can read out the battery consumption from the watch and see if there anything particular that drains it.
-
@egika not sure how well this work on iOS but on Android this battery graph is next to useless.
When I was having my issues with YTM and Spotify eating battery the usage graph was showing all as fins and barely any battery use from anything, yet the battery was draining very rapidly.
I find the numbers rarely add up to anything resembling reality.
-
@olymay cheers for the tips.
I am going to use power save tilt and see how that effect the battery. Hopefully in a positive way. I think my watch does disconnect quite often from my phone. I am 80% confident that it BT issues that could be causing my battery drain. I also uninstalled Spotify
-
@binoworld-uk - if you watch is regularly disconnecting then yes it is going to drain battery. At the very least until you get this issue under control, switch off wifi, as when you lose connection it will auto activate wifi trying to get a wifi connection. However even with that off bluetooth trying to reconnect can drain - its loads better than it used to be, but still not great.
Make sure that the wear os and the suunto app are white listed.Then also check the bluetooth settings on the phone for that paired connection. Also check the wear os and suunto app permissions - allow all permissions.
-
@jamie-bg so, I used the watch in Airplane mode and power save tilt and it does hold it’s charge nicely however, what the point of having the watch without seeing some notifications…. I turned the BT back on and now it’s showing 110% usage next day 82% usage under battery starts. I am using IPhone 11Pro Max
What a joke!
-
@binoworld-uk this sounds like the issue is with the phone. Somehow it is draining the battery, possibly by dropping Bluetooth or something.
The S7 itself has a phenomenal battery for a smartwatch. In the almost two years I’ve had my S7 it’s been connected to three different phones (Pixel 4XL, Pixel 5, Pixel 6 Pro) and it has had amazing battery with all of them. (this is with everything bar AoD turned on, I get >50hrs battery life)
I have seen some other stories of iPhones not playing well with the S7 (and other non-Apple devices).

@olymay to me it does sound like IOS and S7 are Not best buddies
Is there a fix to this or troubleshoot that any other Iphone users could recommend please?
-
@binoworld-uk I do not have this drain with iOS and an S7. How are your notifications set up? Also, are there apps on the watch that may attempt to communicate extensively with the iPhone?
-
@brad_olwin my notification are very minimal approx 5 to 8 a day. I do not have any third party apps installed ans I use a Suunto face. I tend to leave the Wearos app open the background as well.
-
@olymay Update:
I did a full reset of the S7 and the issue is completely gone. I guess every couple of months a reset is probably a good thing
-
@binoworld-uk woop woop! I’m glad all seems to be good
A periodic reset shouldn’t be needed . Keep an eye on it but hopefully this is the end of the issue
-
@olymay Thanks a lot for the power save tilt tip. For some reason I missed this option when I initially set up my watch (maybe because you first have to uncheck the other option.) I also changed the display brightness from medium to low as I don’t see a big difference, at least in the winter. This increased the battery life from ~36h to ~48h average, some days even more. That makes a huge difference for me. I can forget to charge the watch some day and still get 2 nights of sleep recording. Or I can go on a trip for a day without the need of carrying my charging cable. I have several third party apps and get a good amount of notifications, have 24h hr tracking and sleep tracking on. So I’m pretty happy now with this value. Needless to say I don’t get this value with outdoor activity, but with 1-1,5 hours of indoor sports I still nearly get 2 days. Obviously there is really a lot of movement throughout the day that activates the display without actively looking at the watch.
