hi everyone welcome back to wesknows tech news and reviews today we're going to be doing a
comprehensive and utter complete test of the gtr 2e the amasfit gtr 2e so without further ado
let's get into it if you are new to wesno's tech news and reviews we talk about the latest
tech news we do brutally honest reviews and share hacks and tricks along the way
we can be talking about the specs all day long because the master gtr 2e is a great watch it's a
smartwatch that's basically a shortcut a slightly shortcut version of the amasfit gtr 2. it looks
stunning it looks amazing well let's be honest 1.39 inch amoled display with the 326 ppi
just can't look that bad as well as the borderless display it's got 90 sport modes and six of these
are actually auto detected now that's just amazing there's inbuilt gps there's voice control to keep
you happy alexa is coming via an ota update anytime soon now you get so many apps so
much features and functionality such as continuous heart rate monitoring continuous stress monitoring
you have your on demand or spot spo2 readings as well as that you've got your three sleep stages so
you deep your light and rem sleep as well as that it actually records naps as long as they're over
20 minutes on top of that you get pie the personal activity index and we all know about that just
keep the value above 100 points and statistically speaking you're 25 percent less prone to getting
heart disease i can talk about that display for another day because it's just amazing
326 ppi on top of that you got the ambient light sensor so you are going to get auto brightness
you can do always on display you've got so many faces that you can download in the zepp app and if
you're not happy with any of them then of course you do have the choice of actually uploading
a picture from your smartphone to your watch face easy as pie and another thing with amazfit
smartwatches it doesn't matter if you're using an ios device as an iphone or you're using an
android phone and that can be anything from samsung to hawaii to xiaomi it doesn't matter
so that's really quite good now when the gtr 2w has just been delivered to me i've actually done
an intro to the gtr2e and i've put it up against the gtr 2. so if you haven't seen that review
um i'm just gonna have it up in the cards above me right now so have a look at that uh just
to get a feeling of what the gtr2e and in that video i actually show that the difference is so
minuscule so tiny between the two watches yes the gtr 2 the flagship it does have a slightly better
screen the actual glass is 3d instead of the 2.5 d i actually explained the differences there the
gtr gtr2 also has inbuilt storage for music the gtr28 does not have that but the gtr2e does have
a temperature gauge it looks just like it it's only a little bit thicker by 0.1 millimeters so
i doubt you're going to notice that and of course it's slightly heavier by half a gram
so that's not major but anyway that's the gtr2e and i've actually got it right here so there we
go this beast right here that's what we're going to be testing today this is a comprehensive test
where we are testing resting heart rate active heart rate as well as the gps so without further
ado let's get into it so let's start with the accuracy of the gps so we can see from the gpx app
as well as from the polar b tap that i've been out walking for 34 and a half minutes and i've covered
a distance of 3.08 kilometers now let's take a look at what the gtr 2e actually recorded on its
inbuilt gps and here we also see that the walking time or the workout time was 34 and a half minutes
but the distance registered was 3.19 kilometers so we are off by about 110 meters or about three
percent for the wrestling heart rate we're going to be checking what the optical heart rate sensor
on the gto2e has actually measured and we're going to be putting that against the o2 ring
from welloo so that o2 ring is actually medical grade so it's a continuous spo2 as well as
heart rate monitor and here it is so the spo2 ring has actually registered 62 beats per minute as the
average resting heart rate over the night now the gtr2e has actually registered
63 beats per minute the difference is minuscule it's tiny it's almost non-existent and now i think
we're ready to get into the most interesting and exciting bit of this accuracy test we're going to
be looking at the active heart rate as tracked by the optical heart rate sensor on the gto2e
and the polar h10 ecg chest strap so let's quickly look at what the polar h10 has actually registered
so it picked up the average heart rate of 146 beats per minute while the max heart rate was
registered at 167 beats per minute the gtr 2e has actually picked up the average heart rate
at 138 beats per minute giving us a variance of eight beats per minute or five point five
percent so that's an underestimation of five and a half percent now the max heart rate was also
underestimated by four beats per minute or 2.4 percent if we look at the chart we can see where
the problem area is so about three four minutes into the workout we can see that the peak just
sort of drops down and while the ecg chest strap is picking up quite high activity where my heart
rate is up above 140 beats per minute the gtr 2e is just reducing the heart rate and it drops
down all the way to 120 beats per minute and we can see that this underestimation actually lasts
for about four minutes then it does pick up but once again one of the peaks where we can actually
see the 167 beats per minute being reached by the ecg chest strap that's not registered it's cut off
by the gtr 2e then we go down to the throw the throw seems to be fine it does pick it up we can
see an obvious lag in the pickup of the heart rate and in the last three minutes or so of the workout
the gt-r2 is doing a good a relatively good tracing of the ecg chest strap
overall problem areas and this is something that we've picked up on another model from
a mass fit the gts 2e if you recall it also undercuts and underestimates
the peaks of your heart rate i would say the gtr2 does perform slightly better than the gts2e
but still it's way worse than the gtr or the gts2 mini and by the way the gta is too many
wow we love that optical heart rate sensor in basically every test and comparisons against
garmin fitbit samsung it just kills them like the gts2 mini heart rate sensor is amazing
but anyway back to the gtr 2e it's a great watch it does show good potential if we
talk about the other metrics like gps sleep accuracy as well as uh resting heart rate
i think that the gtr 2e actually performed really well we can see that there are no problems again
things are happening when we are working out the peaks are being underestimated and
that's a slight problem i don't think it's major but it's there anyways thanks for watching if you
did find this accuracy test useful then drop us a like and if you want to see more of the same
