one thing i like to do whenever i get a new smartwatch is test how accurate it is
after all it is meant to be doing quite an important job that being keeping an eye on
your heart rate sleep and much more so today i will be testing the heart rate
accuracy and spo2 accuracy of the brand new galaxy watch 4 classic
and put it up against its older brother the galaxy watch 3 to see how things have
improved so sit back relax and stay tuned whilst we explore the accuracy of the new galaxy watch 4.
what's up guys welcome back to tech it easy if you're new around here i'm alex i review
all sorts of different tech so if you're into that please do hit the subscribe button on your way in
today i've dusted off my galaxy watch 3 and i'm going to put it head to head with the new galaxy
watch 4 classic to see if there's any noticeable improvements in terms of accuracy when it comes
to heart rate and sp02 i would have tested the sleep accuracy too but for some reason my watch
keeps telling me that i'm playing table tennis around 11 pm every night for around 20 seconds
not sure what that's about anyway to do these tests i will be using the o2 ring that the guys
at well you provided me for another video this is a piece of medical grade tech which will give
live readings of spo2 and heart rate straight to my phone so you guys can see it live on screen
if you are interested in that device there will be a link to that in the description too without
further ado let's get on with some testing okay so we'll kick things off with the heart rate test
i'll start with the galaxy watch 3 to refresh our memories so i've done five tests for each watch
consecutively worth noting i found the fairest way to do this was to actually turn off the continuous
heart rate it's just too slow to update on the galaxy watch 3 so i can't really get an accurate
reading on camera so it's better if we do both watches in the same way i'll add the clip in of
the continuous heart rate for the galaxy watch 3 later on so you can see what i mean anyway we can
see that the galaxy watch 3 isn't quite hitting what the o2 ring is displaying bang on certainly
in the ballpark but i'm not overly confident about the consistency here we have had a few occasions
where it got very very close so from that we can deduce the galaxy watch 3 is accurate but by no
means on a medical grade level still certainly better than many other smartwatches out there
also worth noting i had just done my rowing session so if you're a little bit concerned
about my super high heart rate that's why now we get onto the galaxy watch four a much more fluid
and consistent experience in my opinion i think it's quite obvious that there are some pretty
big improvements when it comes to accuracy here i found the galaxy watch 4 to be better pretty much
every time even with the off camera test so it's really quite impressive to see what samsung have
done here and i personally think for athletes the galaxy watch 4 classic or the galaxy watch 4
is definitely going to be a better option to get those more precise heart rate readings
next up we have the spo 2 accuracy test starting with the galaxy watch 3 again is pretty much dead
on but always one unit out i find this with pretty much every smartwatch that i test when it comes to
sp02 very few have actually ever matched the o2 ring exactly so absolutely nothing to complain
about in terms of accuracy with the galaxy watch 3 here i think one unit is a fair margin for error
now we come to the galaxy watch 4. it's the same story as the galaxy watch 3 except it did actually
get it dead on on a few occasions this doesn't mean much in the long run but as i said very
few smart watches that i've tested when it comes to sp02 have matched the o2 ring dead on so it'd
actually be inclined to say given the test results of the galaxy watch 4's heart rate accuracy test
that it would be fair to say that the galaxy watch 4 is slightly more accurate in this department too
let me know your thoughts in the comment section down below so that's it for the heart rate and
spo2 actually test for the galaxy watch 4 classic it was a little bit frustrating that i couldn't
get the live readings on the galaxy watch 3 with the continuous heart rate but it should give you
a good idea and a ballpark figure to go off as i always say with the galaxy watches and really any
smart watch they're not intended at the moment to be sort of life-saving equipment so if you do have
any issues always speak to your gp first then again in comparison to a lot of other cheaper
smart watches the galaxy watch 4 is outshining a lot of its competitors i'm just not sure if it can
quite take on the apple watch at the moment let me know your comments on the accuracy of the galaxy
watch for down below also just before we go i do apologize for the lack of content recently
everything's just been a bit hectic i've been so busy but i've got plenty planned for the coming
weeks including a new phone tablet earphones and much more anyway i've been alex this has been
take it easy thank you so much for watching and hopefully i'll see you in the next one
you
