Heart rate continuous monitoring was ON as well as sleep tracking. Continuous strees tracking was not activated.

@@bipr how long did your Galaxy Watch Ultra last on a single charge?

@@ibby81ae The watch lasted 2 days. I will see in the future if it can be more than that...

@bipr was always-on display on aswell?

@@ibby81ae yes with always on display.

@@FabOnABike 8 to 10 hours should be fine. There is also a battery saving workout mode which I didn't test till now... I'll see in the future

Apple watches are great products as well, the HR sensor is for example more accurate.

@@ThatGuyKal There is a little delay between the time you push harder on the pedals and the time your power increases. If all people you are riding with go faster at the start of a climb, try to push harder a little bit before it start to climb. What you can do as well is increasing your FTP parameter.

@@bipr I'm very unfit so I can't push for too long, I don't ride with others, I only solo ride and ride against my ghost. how can I adjust my parameters to be more forgiving for my lack of fitness besides increasing my FTP parameter? Would adjusting my max HR help?

@@ThatGuyKal Max hr and min he should be your real values. Increasing max hr will do the opposite... What FTP parameter did you take?

@@bipr Thanks for taking the time to respond. I'm using a real value for RHR, Max HR I used an estimate, Correct weight and using an estimate for my FTP "How Many KM can you run in 1h" I put 4.5 which is about right based on my last run (very unfit).

@@ThatGuyKal ok the tool is an estimation mainly desgned for athletes, try to increas ftp and dicrease max hr...

I can understand but there is no alternative today and many riders take their phone with them in any case...

Merci

Good question. When I tested it took 10% per hour so expect between 8 and 10 hours I guess. There is a battery saving workout mode but I didn't test it till now.

@@bipr Thank you; so it can cover a triathlon on the paper :)

Thank you!

I completely agree, you can see in the video 6:09 that the Watch SE 2 has an accuracy of 2% which is even better than the Galaxy Watch Ultra. Watch Ultra is the best among Wear OS devices.

The Watch 7 has the same HR sensor so you will get the same results as the Galaxy Watch Ultra. Maybe even better for people with smaller wrists because the watch is smaller and may better fit their wrist! This is a good choice as well. :-)

Sorry? Can you tell me more? I didn't use AI for the thumbnail... I just took a picture of the watch with my Sony camera using my 2.8 FE 90mm macro lens at 5.6 and put text as overlay afterwards. On the back it is my white helmet which is blured because of the depth of field...

7% means the real value is close to 7% to what the sensor gives you. If you have 0%, this means that the gives you always the exact value. Or 100% correlation gives you an exact value as well. My definition of accuracy in the video : standard deviation divided by the mean of the heart rate values. So lower is better.

@@bipr A-ha! So the 7% means how much it deviated from the "true value/base value" which is taken from the Polar H10 (same one that I use, by the way). Thanks the the insight! Great video, by the way! I was already on the fence about getting one, you just pushed me in the right direction! Keep up with the work!

Its 7% inaccuracy or margin of error present in the calculation.

I agree with you, and I think/hope firmware updates will come in the future and improve a little bit measurements.

I got the watch on monday morning, so 4 days ago! I tried to do my best to gather maximum information during this time.

Could you please do a follow-up review? I have heard that the battery life improves after a week of usage.

@@ibby81ae Yes it may be possible that you get more juice after one week, but I don't really know today. I would have expected a bit more battery life given the capacity and the thinner processor... I will continue to test the watch and tell you in the comments in the comming days if it gets better!

@bipr I hope it lasts at least three days with all the features enabled.

@@ibby81ae As of now, 2 days maximum, but I will keep you updated!

The definition of FTP is the maximum power that you can hold for an hour. I agree with this, and I am not sure I could hold 255W for an hour; I think Strava's estimation is probably too high. On the other hand, I know I have never done a 20-minute all-out test, but I was able to hold 240W for 20 minutes. I think at least 240W can be sustained for an hour, but maybe not 255W. Strava takes the whole power curve into account to estimate FTP, gathering data from all your rides. Conversely, Samsung only uses data from the current ride and focuses on the 4-minute power peak. Currently, I am working on FTP estimation based on power-to-HR correlation, but Samsung seems not to use HR data (there was no HR data during the ride). I need to do more tests to better understand how Samsung's FTP estimation works, but I believe it is only based on your 4-minute power peak.If you perform a 4-minute all-out test, you will get an idea of your VO2max power, not your FTP. Even though there are slight differences between individuals, VO2max is often correlated with FTP (if you get fitter, your FTP will increase along with your VO2max). Therefore, it is not unreasonable to estimate FTP based on VO2max. As you suggested, consistency is what is most important. Personally, I don't need to know the exact value of my FTP; I am more interested in how big companies handle this concept. Sorry for the lengthy response!

I appreciate your testing, specially with external sensors. I find the Ultra way too expensive compared to what it brings of extra features compared to the Watch 7 (or the TicWatch Pro); apart from the materials, it's a bigger battery, and the 10 ATM rating, plus the button for workouts. The ATM is a static rating and Samsung one their web site specifically says it's not for diving below 1.5 meters. That's disappointing, compared to Huawei GT4 Pro, Ultimate, Garmin or the Apple Watch Ultra. I had high hopes for the new bioactive sensor and they claim a 30% improvement over the Watch 6 in terms of accuracy in tracking dynamic HR changes, but perhaps it's not enough. It will do other things such as AGEs, and probably more in the future.

​@@GadgetyMV Thanks for your additions! I agree with you that the HR sensor can still be improved. It's 7% for the Galaxy Watch Ultra, whereas it's 2% for the Apple Watch, which is much better...

I was able to do 100km+ rides, so of course it will impact the battery but for a few hours it is fine. Maybe not for ultra endurance rides however... You can turn off GPS in HR2VP on the phone to optimize battery consumption. The screen of the phone needs to be ON, I'm not sure to see what you mean with stand by but if you press the power button to lock the screen once, the screen will be switched off and the app may not work properly. I invite you to try and confirm or not if it works. Concerning the subscription, you can try it for free for 15 minute workouts, in order to see if everything works fine and if so, the subscription is a bit less than 4$ a month. If you prefer to pay only once, the Lifetime is around 35$.

As you can see on the video, chest strap usually give better results although I didn't test the smartband that you mention...

There was a time when my Karoo 2 was off for elevation but it is now back in order, no more issue for me.

@@bipr How did you fix it?

@@1ntrask I did nothing, there should be a firmware upgrade that fixed it... It worked great when I first had the unit, then not so good, then again fine...

You're right, it is a smart idea from Hammerhead. I tried on the Karoo 2 but it didn't work. It is available only on the K3, this is a difference between both devices...

Thanks for the feedback. Unfortunately I doubt Wahoo will fix it and I can do nothing on my side since the connection is initiated by the Wahoo device...

@@bipr aah damn, sad to hear, thank you for answering and the app again, it was great while it worked. do you think it is the device and a newer one would work again? i know the galaxy sport is quiete old, sad i would have to replace it since it is still serving its purpose. guess wahoo wants to sell their own hardware instead 😮‍💨

@@MyMMC Unfortunately, with Wahoo there will be few solutions with newer watches. On Wear OS, the only solution for Wahoo is to use an ANT+ USB stick plugged into your phone with our app 'HR2VP Watch BIke Computer'

@@bipr damn, that would be a massive downgrade. guess i hope wahoo will fix this since a lot of my friends who use the wahoo belt also report issues since that update. thank you.

On which device are you watching the video? The sound was clean on my headset but I try to understand why some people complain about it...

@@bipr Probably people who listen to you on a mono device who cant hear your voice. Because You have an inverted stereo field on your voice track. So in stead of that your voice comes from the center , it comes "not from the center" there are a few seconds where it is correct : between (04:26) and (04:35) your voice channel has a normal stereo field. If you flip the left or right channel in your voice track it sounds normal , i tried. I'm listing through a pair of SC203 speakers on a PC. This also will probably make your voice disappear or go very silent if the viewer listens to your video on a mono device.

@@bipr P.S. you can check this for yourself , in windows settings choose accessibility , and turn on Mono audio , you will still hear the background music , but you will not hear your voice anymore. So anyone with a mono device will potentially not hear your voice depending on how the device handles the stereo to mono mixing.

@@edtim3550 Thanks, I think this has to do with my camera pre amp. In the small extract where it works, the mic was connected to my PC with USB... I will sync in post next time.

You may have some issues with built-in optical sensors at high intensity but for sleep tracking, heart rate is low and you don't move a lot, so it is perfectly fine. What I would suggest is to get a good heart rate monitor for sports only, not for everyday life. My favorite one is: amzn.to/4ahXYCC It is rechargeable, accurate, comfortable, with led indicator, so very nice. If you prefer an arm band to a chest strap (a bit less accurate but OK), this one is good as well: amzn.to/44CwPsG Of course you can pick up a Polar or Garmin heart rate monitor, it is accurate as well but a bit more expensive. It is up tu you to decide :-)

I did and it still doesn't work!

@@emgin4 Did you try with ANT+ or with the data field? If data field, you need to enable broadcasting to the data field, you need your phone with you and the data field needs to be added to one of your screen. HR will be displayed on the data field but not on the native field for heart rate because Garmin doesn't allow developers to override native values.

I added the hr2vp data field to the screen and didn't get anything. Then about an hour later it said trial expired?

@@dboccabella I think there is a communication issue. Is the Companion app 'HR2VP Watch Bike Computer' installed on your phone ? Is Garmin Connect installed on the same phone ? Is your watch connected to your phone ? Is your Garmin device connected to your phone ? Are all permissions granted for HR2VP Watch Bike Computer companion app on your phone ? Do you see a Garmin Service notification popup on your phone ? Is Garmin data field broadcasting enabled on your watch ? (no need for BLE broadcasting) Sorry for all these questions but everything needs to be checked... Thanks

​@bipr yes confirmed all apps installed. Hr2vp says installed on all devices. Changed watch app to data only. Garmin and watch connected to phone. Why does the data widget only give me a 500s trial? Do i need to buy something else?

Yes you are not lucky, the note ultra is the only note 20 which is not ANT+ native... There is a new possibility which is not completely official but it should work: join the beta and get the latest beta for HR2VP Watch Bike Computer. Enable ANT+ broadcasting (even if your phone is not ANT+ compatible). A new Service will run in the background and transmit data to the HR2VP Data Field which you need to add to your profile screen on your Garmin GPS. To get the data field : apps.garmin.com/fr-FR/apps/ab94e897-c1a0-4d5c-9688-89ecfb11126a I am interested in your feedback if you try...

I invite you to check parameters : min heart rate, max heart rate (should be achievable, not theoretical), and set FTP at 235W in the app. If you know yourself, you can fine tune the FTP parameter, it doesn't have to be exactly your FTP. For some people, it is a bit more, other people a bit less... If you want a more stable power out (less sensitive to variations), you can set power values parameter to smooth (or in the middle) instead of accurate. It will be less responsive but more stable. Last suggestion, if you already have a power meter, you can connect it to the app and it will tell you the best parameter to use for the FTP at the end of the workout. This way you can calibrate HR2VP. Another question: which heart rate monitor do you use ? Are you sure it is accurate ?

Hi, yes, it is possible to connect your watch to your Edge unit through your phone with ANT+ today, as described in the video. A new option should be available in the coming days (through your phone as well).

More than enough for me... I think around 20h or more...

You re right, bigger battery life for Garmin and often much more expensive. Can you now answer calls directly on Garmin watches?

On my Garmin Fenix 6S i can answer WhatsApp messages with pre prepared messages and i can pickup an incoming call, i never test to talk during a workout or a ride. I always just stop to be save on the road.@@bipr

Garmin is overrated .Ugly watch faces, terrible sleep tracking, button arrangement sucks. Workout data is the only good thing about it.

Thanks for your feedback!

Yes, it will work with ANT+

@@bipr My S23U doesn't support ANT+ sadly.

@@Dowper It is a pitty that Samsung dropped ANT+ support... There is still the option with an ANT+ USB stick.

​@@bipr Okay, last question - is it possible to run HR2VP app and Samsung Health cycling training simultaneously, so I can see the HR on the Garmin Edge and also record a cycling in Samsung Health at the same time?

@@Dowper Yes it should be possible, the app runs in the background.

Yes

You're right, depending on where you live, it may be hard to find a reseller to see one...

The files are very small and don't take much space, but if you want to delete them, you can go into the Settings of the watch, then Apps, then HR2VP Watch Bike Computer then Clear Data. It will clear all your Settings as well, be sure to enter them again afterwards.

I've got a GW5 and a Wahoo Element. I can add the watch as a HR sensor, but the Element then loses connection/doesn't show the HR. Did you have that issue?

@@GaiusSallustius Yes we are aware of this. This is why we added ANT+ support and did this video. The solution is to use ANT+. Unfortunately, the connection is initiated on the GPS and we cannot fix it on our side for BLE. The watch is both regular Bluetooth and Bluetooth Low Energy and something gets wrong...

Thanks 😊

Thanks, I would choose Xiaomi in your case... New Samsung S24 have now longer Android update support, this is important and add some weight in the balance... But between S23 and Xiaomi I would go for Xiaomi
