Blaze showed less mileage on walk using GPS than Charge HR GPS/Phone

[SunriseGirl]

My daughter and I took the exact same walk together today. We both have iPhone 6S...the difference was I started the walk using my Blaze connected to the GPS through the exercise button on the watch and my daughter used the charge HR and tracked GPS through the track exercise button from her phone. The Results: My blaze only tracked a little over 3 miles while my daughters charge HR tracked a little over 4 miles. Before I switched to Blaze, my charge HR using the GPS would track this same walk also at over 4 miles. Which is the more accurate way...GPS through Blaze watch or through the track exercise button using the app from the phone?

Same issue for me.  Blaze/Fitbit app showed that I did less than 5 miles, while the Nike+ app showed I did over 5 miles.  I also have an iPhone 6.  I'm more inclined to believe the Nike+ app stats.

Mine is really short on my miles, as well.

[ChaneRZ]

Yup short distance here too.

I know of one person who took the same walk on 5 consecutive days, wroth 5 dofferent GOS apps and got 5 different readings. The next week he did it again, only to see 5 more readings. So five apps to runs with each app, for a total of 10 different distances.
Personally i would not run 2 gps apps on the same phone concurrently, i would be concearnd with interrupt delays.

Got my Blaze two days ago but due to bad weather have only used it for the first time today.  I did my regular walk that I've done for some time now and I know what the distance is. S Health (samsung heath) and MapMyWalk both give me exactly the same results in the past. Today using the Blaze for the first time the distance recorded was half of what it should have been.

What is even stranger is when I look at the total Steps for the day by touching the "Today" option on the watch I get the correct distance I have done, yet the actual result in the Exercise it still shows the distance travelled at half what it is actually.

I think somehow the Exercise feature is miscalculating the GPS data for some reason but the main Today figures are getting it right. Just a guess.

I just checked and my steps and calories were a little low for my distance but does not appear equivalent to the approx. 1 mile the Exercise feature shorted me. I just checked and my pace was way off...had me at over a 17 min mile when the same walk I take often using the charge HR and on other separate occasion just using Map My Run always have me walking at 11-12min miles. Thank you for sharing your observations. I otherwise have really been enjoying my upgrade to the blaze from the Charge HR but this is bugging me, LOL

Same here. Tried the blaze on a route I know is one mile. Blaze connected gps only picked up 0.77 miles.

[DavS]

@kathy2424 I got the same result today that you did. The route was about 1 mile (0.98), but my blaze logged it as 0.77. But then I repeated the same walk using the fitbit app and got close to 1 mile.

Same issue for me.  I have walked the same route on my lunch break for years using mapmyfitness and the distance is 1.13 miles.  With the Blaze Walk tracker, I'm lucky if it records .75 miles.  The closest it has gotten is .88 miles.

My run distance however seems to be quite accurate, within .05 of a mile.

I walked 4 miles today and it shows .70 miles.

I have just upgraded to a the Fitbit Blaze but I've noticed than I need to walk approx 300 more steps to make a mile compared to my other two previous fitbits. This equated to just over a quarter of a mile. I notice this post started back in 2016. Can anyone from fitbit please explain why the blaze isn't recording the same amount of miles. Step count appears to be ok but you do not get the same amount of distance for your steps. 

Look forward to a reply from Fitbit

@Cavalierlover2I have found if I walk under a moderate pace, about 2.5 mph (4.0 kmh ) I lose about 20% of the distance. Over that, at a moderate to exercise pace the distance is accurate. Normally my planned exercise walk. But domestics, like carparks, shopping strips and malls is where I lose distance.

This has been happening since March 2016 when I first received the Blaze. All of my other trackers are accurate on distance when using at the same time and under the same conditions.

I have logged this with Support and my case is closed and the data is with Engineering.

I went 2 miles tonight in the treadmill and turned off the gps and the mileage cue. It appears to be working correct. I also think since today was a lot of fog and cloud cover and I was in a gym, the gps wasn't picking up all the time.
