hi everyone welcome back to Wesknows tech news and reviews
today we'll be doing a heart rate accuracy test as well as the gps accuracy test
of the amazfit gtr 2e versus the amazfit gts2 mini without further ado let's get into it
so just recently we have actually tested the amazon gtr 2e versus the corespace 2 and
the amazon gtr 2e just didn't do too well well let's hope that it shows some better
results against the gts 2 many so basically the gts2 mini is the cheapest smartwatch in the
mass fit watch range now the amazon gtr tui as well as the gts2i are the mid-range smartwatches
between the gts2 mini and the flagships the gtr 2 as well as the gts2 so they've got quite a lot
to offer so if the gts2 mini as well as the gto2e have dual input gps they both have amoled displays
they're both water resistant so the gts2 mini has 70 sport modes plus while the amazon gtr 2e has
90 plus continuous heart rate monitoring there is spo2 measurement on both they've got three
sleep stages so they will be measuring your dpu light and rem sleep they will give you advice if
you go to the zep app on your smartphone so there is a lot that these two smartwatches can do also
all sport modes are actually gold based so we can say that these two smartwatches are quite advanced
and most importantly they're from the same brand but the gts2 mini is very accurate even though
it's the cheapest smartwatch in the mass fit range so the gtr2e did have a history previously
when it was just released about six months ago it wasn't too good on the heart rate accuracy
nor gps accuracy but with all the updates that a mass fit has supposedly done we are expecting an
improvement so let's get into the test results so how is the test performed so i was actually
out on a walk from hammersmith bridge all the way down to chelsea so that is an 11 kilometer walk
so i was measuring the gps distance on my samsung s10 while the heart rate accuracy and the heart
rate benchmark was actually performed by my polar h10 ecg chest strap which was on my chest all the
time during the walk and that walk actually lasted for one hour and 50 minutes so first of
all let's look at gps and then we can look at the heart rate accuracy so we know that that walk is
11 kilometers that's the length of the route now let's see what the gts2 mini actually came up with
and we can see that it came up with 10.62 kilometers so off by 380 meters and that
is actually a difference or an underestimate of three and a half percent in regards to the gtr 2e
so here the numbers are not as good because we can see that the numbers were off by 880 meters
and that is quite significant that's a difference of 8 more than double the difference
as calculated by the gts2 mini we can see a big break in the last 30 minutes of the walk and that
is where the gps connection has pretty much failed on the watch it didn't fail on the gts too many
but it did disconnect on the gtr 2e and hence this humongous difference anyway let's take a
look now at the heart rate accuracy so we can actually see that the polar h10 ecg chest wrap
has measured the average heart rate at 104 beats per minute over the one hour and 50 minutes of
walking while the max heart rate was registered at 118 beats per minute let's see what the gts2 mini
has come up with so the gts2 mini has actually registered the average heart rate at 106 beats per
minute which is two beats per minute higher than the polar h10 and the max was registered at 123
beats per minute which is five beats per minute higher than what is registered by the polar h10
so all in all the results are within tolerance limits so the average is off by about two percent
while the max is off by just under five percent now if we take a look at the results from the gtr
2e so the average was measured at 105 beats per minute while the max was registered at 127
beats per minute meaning that it is closer to the average than the gts2 mini
because the overstatement is just one beat per minute or just under one percent
while the max is at by a whopping nine beats per minute and that is around eight percent
that is quite significant and that is way higher than what we have seen on the gts 2 mini so all
in all what are we seeing from the gtr 2e have they been massive improvements in gps accuracy as
well as heart rate accuracy well i can say that compared to the tests that we would have done
ages ago five six months ago when the gto2 was just released yes improvements have been made and
they're visible and evidenced but the gps accuracy is still off by quite a bit but we can see that
the gps accuracy is better but it's still off in regards to heart rate accuracy well this is quite
interesting because we have seen on the gts2 mini test as well as the test against the core space 2.
so the heart rate average is quite sharp but it's the peaks that are just getting overstated
so there is some work still to do by amazfit for the gtr2e and i expect for the gts2
anyway thank you for watching this test review and comparison of the amasfit
gts to mini as well as the amasfit gtr 2e if you did find this test review and comparison useful
