hi everyone welcome back to Wesknows tech news and reviews today we've got a heart rate accuracy
and comparison test between the fitbit locks as well as the xiaomi mi band 6. so i've been doing
a long-term review of the xiaomi mi band 6 just a while back as well as the comparison between the
lux and the mi band 6. and it did turn out that the me band 6 does offer greater value in terms of
a great display great design lots of functionality at only a third of the price from the fitbit lux
but the only point of contention was the actual heart rate accuracy because the lux did show
itself very nicely against the huawei band 6 but now that we've done the test against the xiaomi mi
band 6 we were quite surprised as well so here goes let's get into the details in this test
so as per usual with the comparisons and tests we have a benchmark and that is actually set by the
polar h10 ecg chest strap so the strap is on me on my chest while i'm doing the workout and that
records the most accurate heart rate that can be done well physically today because the polar h10
ecg chest wrap is actually used by scientists and professional athletes and so far and today
it is the most accurate chess rep that can be found in the market so that is our benchmark
so let's talk about the test rules so what happened i went to the gym i got onto the
treadmill then i did a couple of core exercises as well as weights exercises just to keep up the
heart rate and to keep it intense enough and to give us the steps that we need to actually
attest to the accuracy of the optical heart rate sensors on the back of the two trackers so let me
tell you quickly about the two trackers and then we can get into the test results okay so the mi
band 6 is a truly budget fitness tracker 40 bucks will get you a 1.6 inch amoled display fully touch
activated it looks absolutely amazing 30 sport modes all of them kept on your fitness tracker
and you get six auto detected activities which is amazing now it does get connected gps as well as
that it's 5 atm water resistant that means that you can take it to the shower to the pool because
it will do your stroke recognition it will count your number of laps it will calculate your swarf
and in general it's got all the other fitness tracker functionality such as it's got a breathing
widget it can monitor your stress it can monitor your sleep in three sleep stages so you light your
deep and rem sleep the watch also gets an spo2 monitor so it does measure your blood oxygen
saturation also there's a world clock there's the usual alarms there's a weather widget you can get
your timer and stopwatch all the rest of it is on there but you get that for 40 bucks in regards to
the fitbit locks well this is a premium fitness tracker well that's how it's actually positioned
by the marketing campaigns but really all you're getting is a really big black face
and in the middle of it there's a small amoled display a rectangular display which is less than
one inch so really quite tiny it's also amoled so it's also bright and crisp but it is small
fitbit is telling us that sp02 is coming to it later by an ota update you get 20 sport modes but
only six are actually kept on the tracker if you want to switch around the activities you will
have to go to your fitbit app and choose the sport modes that you want on the watch from the actual
app also with the fitbit locks you actually get a six month premium subscription absolutely free
but you do have to splash out 130 pounds or 130 so that is quite a bit in regards to all the other
features well you also get them on the fitbit right you also get your silent alarms you get
your weather widget uh you've got your timer you've got your stopwatch all the basic stuff
is on there so you get your light your deep and rem sleep monitored so just in general it looks
like any other tracker but it costs three times as much it's got a much smaller screen
the purpose of this test is to attest to the accuracy or the heart rate accuracy of these
two trackers because really you do get a fitness record to identify and to monitor your heart rate
or the intensity with which you perform certain activities so let's have a look what the results
were for the two trackers and set up against the benchmark the polar h-10 ecg chest strap
so let's start off with the polar h10 ecg chest wrap results so what we can see that over the 25
minutes the average heart rate was measured at 109 beats per minute while the max was registered at
beats per minute let's take a look at what the fitbit lux came up with and
this is where things just get very interesting because once again the fitbit locks it just
nailed it the heart rate average was measured at 108 beats per minute that's less than a percent
of the mark if we take a look at the max heart rate it was measured at 132 beats per minute
and that is also less than one percent variance that is wow astounding and if we look at the two
charts we can see that the spikes do replicate each other they go on track and now if you take
a look at the results from the me band 6 this is unfortunate so we can see that a budget tracker
it just didn't act as accurately as we expected so we can see that the average heart rate was
measured at 115 beats per minute that's off by six beats per minute or just over five percent
in regards to the max it was off by 16 beats per minute and that's 12.2 percent that is
quite a significant variance in such a small time frame 25 minutes well it's not minuscule
but it's not large enough and we can see that it's not just one spike causing this error the
first large spike on the actual plot that's where the problem is and it's not a single point on the
plot there are quite a number of points and they all seem to be driving up way too high
well these are the results so what can we say well yes the fitbit locks is the more dear option
it might not look as cool it might lack some of the functionality but if we talk about heart
rate accuracy as was proven with the test from the huawei band 6 as well as against
this particular test against the mi band 6. the fitbit lux
heart rate accuracy of the optical heart rate sensor on the back of it is mighty good anyway
