Transcripts

imagine an Apple Watch but with better

battery life and close to half the price

tag well that's what the Huawei watch

fit 3 promises to be and it's also

compatible with both Android and iOS on

paper it seems to address many of the

common complaints people have about the

Apple watch but that's not why many of

you have been urging me to review it the

bus is all about huawei's claims of

improved health and sports tracking So

today we're diving into my initial test

of the Huawei watchfit 3 and I have to

say in terms of design at least this is

my favorite Huawei product in a while I

think the new square shape is just so

much nicer than the elongated shape that

the previous Huawei watch fit had but

enough about the Statics and

specifications let's jump straight into

the testing and see how the Smartwatch

really performs as always I want to

start off with a heart rate tracking

performance and here you can see an

overview of that performance for one of

the easiest exercises for a watch the

track indoor cycling which I tested

myself for three sessions now I already

did more testing but one reason this

review took longer than normal because

I'm having issues getting to the raw

data from the Huawei app so I have to

rely on a limited data set for now

however I still think the data is good

enough for some solid First Impressions

now to test the heart rate tracking

performance I'll compare the

measurements against the polar h10 ECG

chest trap which can generally record my

heart rate very accurately each dot in

this plot is a single heart rate

measurement with long the horizontal AIS

the value according to the polar H and

HG chest strap and on the vertical AIS

the value according to the watch fit 3

now the closer the points are to this

blue line the better the agreement and

the darker black the color the more dots

that there are and as you can see this

generally looks pretty good actually

most points are on or close to the blue

line at least interestingly mostly in

the lower heart rate range right here do

we see a bit more deviation both below

the blue line but especially above it

also here in the medium heart rate range

still this looks really good and the

correlation is quite high at 0.98 so

that's this R value up here and this

value cannot be higher than one so a

correlation of 0.98 is pretty good but

let's take a look at the individual

spinning sessions to see why we have a

deviation especially here in the lower

heart rate range and here we have the

first example interval spinning session

where we actually see a pretty decent

agreement between the watch fit 3 and

the ECG chest trap in the higher heart

rate range is almost spot on but in the

breaks between my segments there's a bit

more deviation we can see some right

here and also right here there's a tiny

bit more deviation but overall honestly

this looks really good and for this

spinning session it looks even better

honestly every time I took a break it

caught it almost perfectly so that looks

really good and for this final short

example we see some deviation for

instance right here and a little bit

right here but again overall this would

be good enough for me next let's compare

this performance that of other watches

because at least looking at the results

so far it seems quite good but another

watch might actually perform better by

the way for those of you that are new to

the channel my name is Rob and I'm a

postdoctoral scientist specializing in

biological data analysis I should also

note that Huawei sent me the watchfit 3

to test but it will go back to them

after I'm done testing but okay back to

the results and the testing and that

overview is displayed right here now a

correlation value I was talking about

before is the metric I'll use for this

which is displayed along the horizontal

axis and we want that value to be as

close to one as possible and on the

vertical axis I order the watches from

worst to best so the further to the

right and the higher devices the better

is its correlation with the reference

device and here I marked the huawe watch

fit 3 and red and as you can see it's

amongst the top performers it has one of

the highest correlations out there and

most watches are performing more poorly

but let's zoom in a bit so we can

actually read these labels and here we

have that zoomed in view with just the

watches of a correlation of 0.90 or

higher so just a better performing

watches and even amongst these the

Huawei watch fit 3 is one of the better

performers it's actually super close to

the Huawei watch Fit 2 so I suspect they

perform more or less similarly and it's

in between the 41 and 46 mm versions of

the Huawei watch GT4 so overall very

similar in performance to other Huawei

devices not better or worse I would say

only the Apple watch is still clearly

outperforming the Huawei watches they're

really a lot better than the rest but I

suspect the Huawei watch F 3 is good

enough in performance for most people

and if you're curious other watches that

are close are for instance the pixel

Watch 2 which is also a good performer

on Android but with poor battery life

and also the polar Varity sense a

dedicated heart rate monitor so the Hua

watch 3 is doing quite well compared to

the competition ition overall the watch

fit 3 is doing really well for the price

at least for indoor cycling it's not

quite as good as the Apple watch but

it's super close and given the

difference in battery life and price

that's quite impressive honestly a

cycling indoors is a relatively easy

exercise for watch your track so let's

make things much more difficult and

let's see how the huawe watchfit 3 did

for cycling outside this is a lot more

difficult because of the increased

bumpiness and increased tension on my

arm let's have a look and as you can see

for cycling outside we do have a

slightly decreased perform performance

compared to cycling indoors but honestly

it still looks pretty good the

correlation is now 0.93 so not quite as

high as the 0.98 from before but still

pretty good and we again see that in the

higher heart rate range the device is

really accurate so most points are on or

close to the blue line and most

deviation is here in the lower heart

rate range this is actually opposite to

what we see for many other devices where

many other devices tend to be better in

the lower heart rate range for cycling

outside it appears to be the opposite

for the Huawei watchfit 3 but let's take

a look at the individual rides to see

why this could be now as I said in total

I did six different rides and this was

the longest one by far so over 2 hours

and you can see here that in the higher

heart rate range it seems almost spot on

only in the lower heart rate range do we

see a bit more deviation so again this

explains what we saw in the overview

plot but because this ride took so long

it did have a relatively big

contribution to the overview plot we

were looking at before and I do have to

say the second ride I wanted to share

was the worst one out of all six rides

so here in the beginning it had quite a

big deviation from the reference

detecting a way too low heart rate later

on it's actually a lot better but most

rides are luckily a lot better this one

still struggled a little bit as you can

see right here but also here near the

peaks of my heart rate but this R for

instance in general looks a lot better

though there's a bit of deviation right

here and in this final example we see

pretty decent agreement this is a lot

better than what most watches do so it's

not perfect but it might be good enough

but to answer that question let's see

how it performed compared to other

watches out there and here we have a

similar overview to before but not for

cycling outside and again we want the

watches to be as far to the top right as

possible and as you can see the Huawei

watch fit 3 in red is again amongst the

top performers which is really good and

again it's really close to the Huawei

watch Fit 2 but we need to zoom in to R

those labels and here we have that

zoomed in view within this case just the

watches of a correlation of 0.7 or

higher and as you can see even amongst

these better performing watches the

Huawei watch fit 3 is doing really well

it is doing a tiny bit worse in this

overview than the hu watch Fit 2 the we

can in no way claim this difference is

significant since they only have a

limited set of data for the watchfit 3

still overall both the watchfit 2 and

watchfit 3 are some of the top

performers out there even seemingly a

little bit better than some of the other

bigger Huawei devices that could have to

do with their weight or again it could

be random chance but we actually see

that the GT3 Pro is doing a bit better

so I wouldn't be so sure of that I think

again that many Huawei watches are

performing more or less similarly the

only one again outperforming them is the

Apple watch so if you want the best hard

rare tracking on the wrist the Apple

watch really seems to be best at that

but different Huawei watches are close

second other good devices include for

instance the similarly priced fibit

charge 6 the pixel Watch 2 which is more

expensive and has a poorer battery life

and the coral Space 3 might also be good

enough still overall the W watchfit 3 is

doing really well so I'm not

disappointed so far so also for cycling

outside the watch fit 3 is doing really

well it seems to be amongst the top

performers though I would like to see

some more data to be sure that what

we're seeing is reproducible in the long

r run especially given the relatively

easy longer ride that was included next

let's take a look at one of the hardest

exercises for watch the track however

before showing you those results I'm

hoping that my diligent testing has

earned a subscribe from you and it also

really helps me to get access to devices

sooner if you leave a like or a comment

but enough self-promotion let's take a

look at the performance of the huawe

watch fit 3 for weightlifting

weightlifting is one of those exercises

that most watches struggle with because

there's so much tension on my arm and

the same is true to degree for the Hua

watch three we can indeed see that

there's more deviation from the Blue

Line than before and especially many

more points below the blue line right

here but still overall compared to other

watches this isn't as bad the

correlation is a lot lower now at 0.81

but again compared to other watches it

could be a lot worse but here we really

need to take a look at the individual

weightlifting sessions to see how big

the problem actually is and here we have

the first weightlifting session I wanted

to share with you with again the polar

h10 in blue green and the Hua watch fit

3 in red and as you can see only some

Peaks were fully captured by the Huawei

watchfit 3 some were partially captured

and some were not captured at all so

it's a bit of a mix some parts of the

training were really good whereas others

weren't so good and we see something

similar for this second weightlifting

session it's far from perfect missing

many of the peaks in my heart rate and

that's also what we see for this final

example I wanted to show you right here

especially here in the beginning it

struggled here in the middle it's a bit

better and near the end there it's a bit

of a mix but let's compare it to many of

the other devices out there and here we

have a similar overiew to before but now

for weightlifting and in this case the

watch fit 3 is in the upper middle class

of watches but not amongst the actual

top performers and the why watch Fit 2

is and I'm not sure why that is I'm not

sure if this is just random chance with

a better data collection for the

watchfit 2 or if there's actually

something better about it so I really

need to collect more data the watch fit

3 is close to some other Huawei devices

the GT4 in this case also the Huawei

band 7 but some other Huawei devices are

seemingly doing a bit better so the

watchfit 2 we were looking at before but

also the GT3 Pro but again I don't know

if this is because of the type of

exercises I did or what's going on here

it could for instance be that I did more

lower body exercises for some of these

tests and I did actually no lower body

exercise with the watchfit 3 and lower

body exercises are generally easier for

a watchfit track so I have to collect

more data and see overall the heart rate

tracking performance of the huawe

watchfit 3 is quite good in my opinion

it's not quite as good as the Apple

watch but given the increased battery

life it's doing really well actually we

also potentially saw some slight

differences in performance compared to

the previous Huawei watchfit 2 but I

don't dare to call those different

significant based on the limited data

set I collected so far and for those of

you that are wondering unfortunately I

couldn't do a test for running outside

because of an injury still overall I'm

quite happy with the performance of the

yat fit 3 so far only for weightlifting

I cannot recommend it but for the other

sports so far it's doing quite well

therefore overall I'd give the heart

rate tracking performance four to maybe

even four and a half out of five stars

but that's considering the price but

what about the Sleep stage tracking H

introduced the new huawe creu sleep 4.0

algorithm for their sleep tracking but

is it any better than the previous

generations let's take a look to test

the Sleep stage tracking performance

I'll compare the Huawei watchfit 3

against the zMAX EG headband which can

actually measure my brain waves now this

device also has its limitations

especially when it comes to detecting

awake time but they give us a rough

impression of the Sleep stage tracking

performance of the watchfit 3 and here

are show an overview of the results for

a total of four nights now on top are

the sleep stages as recorded by the zMAX

EG device and the left are the sleep

stages as recorded by the watchfit 3 and

each column here sums to 100% meaning

that we can see what percentage of each

of the sleep stages according to the

zMAX was predicted as each sleep stage

by the watchfit 3 and if they perfectly

agree all values on the diagonal should

be 100% now first of all we see that

only about 36% of what was deep sleep

according to the EG device was also

detected as deep sleep by the W watch

fit 3 so that's not very good more of it

was actually predicted as being light

sleep instead at about

45% now light sleep agreement is also

not that great at about 45% and a lot of

the light sleep detected by the EG

device was actually predicted as being

deep sleep or Ram sleep by the watch fit

3 RAM sleep agreement is similar at

about 44% agreement and about the same

amount was actually predicted as being

light sleep instead at about 40% so

overall not looking very good for the

watch fit 3 now awake time is something

we will definitely not be focusing on

because the zMAX s detect a lot of awake

moments some of which I think are not

really awake moments or just short

arousals and those are not interesting

for us but just for completeness about

29% of what was awake time according to

the EG device was also detected as a

wake Time by The W watch fit 3 now

looking at the Knights themselves will

help us understand that even better and

here you can see the first night I

wanted to share with you on top we have

the sleep stages according to the zMAX

EG headb with along the horizontal axis

the clock time and my sleep stag is on

the vertical axis and on the bottom we

have a similar plot but now for the

huawe watchfit 3 and in purple right

here I highlighted the deep sleep as

recorded by the EG device and as you can

see there's marginal agreement with the

watch fit 3 some of the Deep Sleep has

at least some agreement but later on the

Deep Sleep detected by the watch fit 3

differs a lot it detects a lot of deep

sleep right here later in the night and

this is not what a typical night of

sleep should look like you have most

most deep sleep in the first half of

your night and you have most R sleep in

the second half of your night and for

the watchfit 3 it appears to be opposite

in this case so this is not looking that

great now the general patterns might

look a bit better for this second

example night so with more deep sleep in

the first half of the night and more R

sleep in the second half but the overall

agreement with the EG device is still

not very good though arguably a bit

better but overall this isn't looking

very good and also the ram sleep

agreement isn't very good so here I

marked the ram sleep as detected by the

EG device in red and as you can see this

doesn't match very well with the

watchfit 3 but some of the ramley

patterns might slightly match so this

first second and fourth R sleep segment

show at least some overlap but the

duration is different and this third one

is completely missed and for this second

example night it looks arguably even a

bit worse so in the beginning there's

basically no overlap later in the night

it might be a bit better still generally

I wouldn't rely on the ram sleep

tracking of the watch fit 3 and again I

said we wouldn't focus on awake moments

but just to show you that the General

pattern shows some agreement the longer

awake moments sometimes agree between

the EEG device and the watchfit 3 so I

wouldn't really trust the EEG device

here but if we just look at the longer

awake moment so this is the longest one

right here this was also detected by the

watch fit 3 and looking at this second

night we see por agreement but the

moment I fell asleep and moment I woke

up at least roughly match and for this

third example night I wanted to show you

we see that the two longest awake

moments agree between the watch Fit 2

and the EG device and also the moment I

fell asleep and woke up are pretty much

much in line so though we cannot really

judge the awake moments detected by the

watch fit 3 this might actually be the

best out of all the sleep stages so the

Sleep stage tracking performance of the

watch fit 3 just doesn't seem that great

both the deep sleep and RAM sleep

agreement are quite low and only the

awake detection seems potentially decent

enough so my first instinct is that you

can use the watch fit 3 to detect your

total time and bed and maybe your total

sleep time but even with the new true

sleep 4.0 algorithm you cannot really

rely on the sleep deep stage tracking

however let's put these results into

context and let's compare them against

the performance of many other devices

out there and that is exactly what we

can see right here so this graph shows

an overview of the agreement of

different watches with different

reference devices along the horizontal

axis we have the average agreement over

the individual sleep stages and on the

vertical axis we have the agreement of

the worst sleep stage so the better the

agreement the more to the top right the

devices now this overview is slightly

complicated because they use different

reference devices the device is not

marked in any color were tested against

the dream 2 EG headband my normal

reference but dream band bankrupt so I

cannot use it anymore the devices marked

in green were tested against the zMAX EG

device so the one we used in this video

and the devic is marked in blue purple

were tested against polography or phsg

so the gold standard in sleep stage

tracking and you can see the Huawei

watchfit 3 right here so it's actually

really close to some other Huawei

devices so for instance the Huawei

watchi D4 both the 46 and 41 mm versions

but also the Huawei watch Fit 2 tested

with a different reference device though

but overall it seems to be in the same

area as I always find Huawei devices so

in the lower half right here so really

among some of the poor performing

watches if you want some of the best

sleep stage tracking out there on me

Apple watches perform very well but in a

recent video I made we saw that aura

ring and apple are some of the top

performers out there if we also include

the scientific literature other devices

that are doing really well include the

eight S pod so both the three and four

are performing about the same I would

say and in the group of second tier

devices we have different Fitbit and

Google devices so Google owns Fitbit and

likely use this same algorithm across

all its devices and also the strap

is quite good not quite as well as for

instance Apple Aura and eight S but

still doing really well and whoop is a

better Sports Tracker than Aura for

instance so it really depends on what

you're looking for but both Aura and

woop require a subscription which is not

so nice there are different FIB devices

out there though that have decent sleep

stage tracking and for now at least it

doesn't require a subscription for the

Sleep stage tracking so overall the

sleep stage tracking performance of the

watch fit 3 just isn't very good at

least it doesn't seem to be on me if you

just want to know roughly how much time

you spent in bed or time with sleep it

might be good enough however this first

testing seems to indicate you might not

want to rely on the actual sleep stages

therefore overall I'd give this sleep

stage tracking performance of the Wu

wfit 3 two out of five stars next I

would normally do a complete test of the

GPS tracking during cycling but

unfortunately I don't have enough data

for that as of yet however I do want to

share my first impressions but but

before doing that I'm planning to start

back up with my newsletter after the

summer to share my first results with

you sooner and if you're interested

check out the link up here now the way I

normally test these devices is that I

cycle the same route maybe four or five

times to see how well the signals

overlap and if it watch is good at GPS

track and you'd expect the signal to be

very close however so far I only tracked

the same route twice and those results

are displayed right here I want to warn

you though to take these results with a

very large grain of salt now I never

give watches any extra time to acquire

the GPS signal and in this case I

started one right right here and one

right here so one time it maybe took

half a minute for it to acquire a GPS

signal but overall this is very fast and

if we then look at the consistency

between the signals this is actually

quite good the signals are very close

together showing very little deviation

maybe a little of deviation right here

and right here a bit more right here but

the overall track is looking really good

now we only have two signals so we don't

want to over interpret these results but

generally the signals seem to be quite

close together so that's looking really

good they might deviate a bit from the

road but it could even be that this map

overlay isn't perfect so overall this

just hints at potential good GPS

tracking by the Huawei watch fit 3 the

one thing I did notice though is that

the signal seem to be a bit smooth

potentially so when I go around the

corner it seems to be a bit smooth out

so it might be artificially smoothing

the result making the consistency

artificially seeming a bit better and it

might even be using the map data to push

the signals on top of the road so even a

further artificial Improvement but we

cannot really be sure of this still

overall this is a good first impression

I don't have enough data yet to draw any

definitive conclusions about the GPS

tracking performance of the huawe

watchfit 3 however at first glance it

does look promising overall the watchfit

3 seems like a solid device for about

€60 or dollars you get good quality

heart rate tracking and what seems to be

decent GPS tracking however the Sleep

stage tracking just isn't very good so

it's only used to track my total time in

bed considering the price point and the

good battery life it is a solid choice

and it could be an Apple Watch

alternative for those people on Android

focusing on Sports tracking or even for

people on iOS that don't like the

limited battery life of the Apple watch

I should note though that it might be

difficult for people in the US to get

any Huawei device and also this hu

watchfit 3 and it might take a while for

it to be listed on Amazon additionally

there's also one small thing that bugs

me personally about this screen of the

watch fit 3 now this might be my slight

OCD wearing its head because overall

it's a beautiful display but see it

every time I look at it and that is that

at least optically the bezels on top and

bottom seem to be slightly bigger than

those on the sides again this is a super

small thing and really quite personal

but for me it does take away from some

of the beauty of this device all in all

though I do like the huawe watch fit 3

and I have no problem recommending it to

people that want a well-priced

SmartWatch with good hard rate tracking

therefore overall I'd likely give it

about 3 and a half out of five stars

generally but given the low price I

might just bump it up closer to four

stars with the caveat that the Sleep

Sage tracking just isn't reliable enough

now of course the results I showed you

today might vary from person to person

reviewers if you do decide to get a

Huawei watch a whoop strap an aura ring

all on Amazon for that matter even
