the meme x4 may very well be one of the best smartphones of the
year so far thanks to being the world's first phone powered by the snapdragon
8 plus chipset and being xiaomi's very first mass-produced smartphone to house an under
display selfie camera but one of my favorite things about the meme x4 is the return of 120
watt fast wired charging which was last seen in the mi 10 ultra last year the xiaomi mi mix 4 is
packed with a 4 500 milliamp hour battery split into 2 250 milliamp hour cells and utilizes mtw
multi-pole technology which apparently increases charging speed and reduces charging temperature
the mix 4 has been packed with a new feature known as boost mode which can apparently charge
your phone faster between zero and eighty percent i wonder what's going to happen in the last 20
if it does revert to default how slow will that be though it shouldn't revert to default since
i have made sure to disable optimized charging which usually caps your battery at 80 percent and
trickles through the last 20 percent i will also be using an infrared thermometer gun which i will
test out on the phone every 10 percent of course the meme x4 does come with the massive 120 watt
charging brick in the box it is 20 volts by 6 amps which equals 120 watts i've also managed
to get my hands on a power consumption watt energy meter which will be at the bottom left
of the screen throughout the video just to see if we are truly hitting 120 watts all the time
xiaomi already has a concept phone that sports 200 watt wide charging but until that technology
is available to the public 120 watt will have to do with that said can the me mix 4 charge faster
than the mi 10 ultra and if so by how much this is technic and without further ado let's find out
before we get things going it is worth mentioning that we do have the percentage of the mix four at
the top of the screen we will be doing different brackets throughout the test one to ten percent
ten to twenty percent so on and so forth within these brackets i will be measuring the minutes
not from one to sixty percent for example but it will be from 50 to 60 percent so maybe once or 10
is one minute when i go from 10 to 20 it might be another minute but i won't add them together
at the end of the test i will give a total minute score from zero to 100 which you can honestly just
check throughout the test at the top left corner when you take a look at the timer over there and
the percentage right at the top of the screen like i mentioned before of course we will also be using
the included 120 watt charging brick and 6 ampere cable that came bundled in the box and popping the
mix 4 on charge for the first time tapping the starter time at the top left hand corner that
charging animation looks fantastic it says 120 watt max so it can do anything below that we're
sitting at around 100 watts for now after just one minute we got 10 after two minutes we got 20
and we are getting to the 30 in just over three minutes which is fantastic reaching that 40 mark
in just four and a half minutes and getting to 50 this phone is ridiculously quick at just under six
minutes moving on to the 60 mark we're hitting in just seven minutes and moving through to that 70
mark something strange happened this is the longest period which it took to charge i did have
boost charging enabled and charge optimization disabled but it was doing something strange and
only charging at 10 watts i decided to unplug it for a millisecond and plug it back in it
didn't really improve it so i decided to go ahead and disable boost charging enable it again and
still it wasn't really improving i guess it is kind of that point in time where it tries
to cool down which makes sense since after 60 it reached almost 54 degrees in celsius so it
needed to start cooling things down now it is starting to speed up again reaching that 100
mark in no time unfortunately it didn't do it in its advertised time of 15 minutes but it has
done it in 21 minutes which is still absolutely phenomenal to reach 1 to 100 on the xiaomi mi
mix 4. now before we start speaking about how it compares to other devices around it is worth
checking out this table that i kind of brush through throughout the test one to ten percent
and ten to twenty percent were the quickest just doing one minutes each in those interval brackets
and the ten to twenty percent mark had the highest milliamp hour per minute reading of 450 million
powers per minute now you've also got to bear in mind that that milliamp hour per minute reading
is for between the bracket of 10 and 20 and not necessarily between 1 and 20 20 to 30 percent
all the way up to 50 to 60 percent wasn't bad but reaching that 50 to 60 points we kind of
reached our peak and the phone started getting hot reaching 53.9 degrees in celsius which means that
between 60 and 70 percent we had the longest 10 jump of 5 minutes and 9 seconds but you can
notice that after the 70 mark it did slightly drop in temperature down to 50.4 degrees in celsius
and it dropped again once reaching 80 percent and in that 10 minute bracket it started increasing
its milliamp hour per minute reading and going to the 90 mark it started getting hotter again but
that is because it started increasing its wattage speed and getting 203.01 milliamp hours per minute
then it started to try cool itself down again between 90 and 100 which slowed down the
milliamp hour per minute reading of 121 121.08 and decreased the temperature just by a 0.1
the meme mix 4 did its first 50 in six minutes which is insane it got a million power per
minute reading within that first fifty percent of almost four hundred million hours per minute
it matched the six minute zero to fifty percent of the vivo iq7 and that got a 333.3 milliamp hour
per minute reading within its first fifty percent you've also got to bear in mind that the iq7 has
a significantly smaller battery than the mix four at four thousand milliamps as opposed to the four
thousand five hundred milliamp hour cell on the meme mix four now the mi mix four black shark
four pro and xiaomi mi 10 ultra all have the same battery capacity at 4 500 milliamps and 120 watt
charging but the black shark 4 pro did the first 50 in just seven minutes with 321.4 milliamp
hours per minute reading within that first 50 and the me 10 ultra with the same size battery
and same once it's charging did the first 50 in 10 minutes when it comes to overall score the iq
7 was still up at the top doing 0 200 in just 16 minutes then we had the black shark 4 pro doing it
in 17 minutes the me max 4 doing it in 21 minutes but the me mix 4 was still a hell of a lot quicker
than the 28 minute me 10 ultra also do bear in mind that these are my own test results which i
have personally done on my channel and these are not the advertised times of these phones or other
channel charging test results and in terms of temperature the hottest peak temp throughout the
test of all four of these devices was indeed the me mix 4 with 53.9 degrees in celsius which makes
you wonder if the mtw multi-pole technology which is used in order to increase charging
speed and reduce temperature really works in favor of the temperature side of things
even though recording this charging speed test didn't really take that long just 21 minutes
thanks to the ridiculously fast charging meme mix for the post processing and editing this
video putting it all together took a hell of a long time so if you have yet to do so please make
sure you smash that subscribe button down below stay tuned for my full review of the me mix 4
which should pop around in the next few days this is tech neck and i'll catch you in the next one
