the iphone 13 pro max houses the largest battery cell in iphone history but unfortunately
apple have kept the same 20 watt charging capabilities as its predecessor even though
the battery capacity has jumped up by 665 milliamps which means that it should take
even longer to charge when compared to the 12 pro max the two iphones will be competing in
this battery charge test alongside the samsung galaxy s 21 ultra huawei p50 pro and xiaomi mix
4. the iphone 13 pro max has a 4 352 million power battery and supports up to 20 watt charging i'll
be using the official 20 watt apple charger which is sold separately the iphone 12 pro max has a
significantly smaller battery at 3 687 milliamps which also supports the 20 watt apple charger
which i'll be using today the galaxy s21 ultra has the largest battery cell of the lot at a whopping
5 000 milliamps and can charge up to 25 watts using the official samsung super fast charger
which is also sold separately the huawei p50 pro has a 4 360 milliamp hour battery capacity
and utilizes 66 watt supercharged tech and since the p50 pro doesn't get bundled with a charger
either i'll be using the honor magic 3 pro pluses 66 watt block since it is the exact same charger
and last but not least the xiaomi mix 4 has a 4500mah battery and crazy 120 watt
charging capabilities and yes xiaomi includes the massive 120 watt charging brick in the box
i am extremely excited to get things going this is tech neck and without further ado let's go
before we get things started it is worth checking out the battery temperature at the start of the
test while they're all currently unplugged and not plugged into charge we will be comparing this
during each time interval and that time interval that you can see is in the top right hand corner
and is in relation to the battery percentage above each phone and below the branding of that device
after the five minute mark interval we have eight percent on the iphone 13 pro max three percent on
the 12 pro max very strange over there nine percent on the s21 ultra 16 on the huawei and
29 on the mix four and i have also made sure to disable all forms of battery optimization on all
devices and super fast charging is indeed enabled on the s21 ultra with the coolest phone so far
being the 12 pro max and hottest being the xiaomi after 10 minutes we have 15 on the 13 pro max 12
on the 12 pro max no pun intended over there 15 on the s21 ultra matching the 13 pro max 29
on the huawei 52 on the mix for after 10 minutes which is crazy now 74 on the mix four after just
15 minutes 38 on the huawei 23 on the s21 ultra and 13 pro max and trailing the pack is the 20
on the 12 pro max reaching that 20 minute mark interval getting 31 on the iphone 13
pro max which has now exceeded the s21 ultra is 29 which is now matching the 12 pro max is 29 46
almost 50 on the p50 pro and a whopping 86 percent on the mix of four the previous time i tested out
the mix forward actually did it in 21 minutes pretty strange to see that it's sitting at 90
after 25 minutes and yes it is still the hottest interval and peak in terms of temp with the lowest
interval temp being the s21 ultra and the lowest peak temp in the p50 pro the xiaomi does decide to
say hey i'm first anyway even though i charge slower than next last test at just under 30
minutes over here 30 minutes to be precise with 3.33 per minute and 150 milliamp hours per minute
not too bad though it did get pretty hot at around 50 degrees throughout the entire test its first 80
was at 19 minutes which is fairly decent but like i said it did score 21 minutes the last time i
decided to charge it up but it is ridiculously hot here in shanghai after 45 minutes we have 61
on the 13 pro max matching the 12 pro max now 52 on the s21 ultra really lagging behind here and 81
on the huawei p50 pro with the p50 pro now being the coolest in terms of interval temp and the
lowest peak temp over here doing a great job there with the hottest interval temp being the 12 pro
max strangely enough and the p50 pro decides to clock out at just shy of 60 minutes which
is actually still pretty quick though not quite as quick as the huawei mate 40 pro that i tested out
earlier on this year with a very similar sized battery style and same wattage we'll
get to that a bit later 79 on the iphone after an hour and one minute on the 13 pro max that is
just one percent behind that the 12 pro max it's 21 ultra at 69 but now it has boosted
all the way through to 84 once we hit that one hour and 15 mark interval which is now matching
the 13 pro max and lagging behind this time is the 12 pro max with 82 i have made sure and it
does say super fast charger connected to the s21 ultra and i have compared it to other tests
i've gotten just over an hour before for the x21 ultra my last test was an hour and 14 minutes
it's strange to see that after an hour and 30 minutes it's still not done yet sitting at 93
matching the 13 pro max though the 13 pro max you got to remember does have a much smaller battery
than the samsung even though it has a weaker well less wattage block at 20 watts as opposed to the
25 watt block in the samsung samsung did finish charging it said at the bottom of the always on
display over there at the one hour and 36 minute mark interval which is not terrible though not
the fastest i've seen from the s21 ultra still pretty decent with the lowest end temperature here
amongst the three devices on the right hand side after an hour and 45 minutes 99 on the 13 pro max
94 on the 12 pro max and the 13 pro max finishes in one hour and 47 minutes which seems okay for
an iphone with the largest battery ever seen in an iphone pretty decent ending off with a temperature
of 35.8 degrees in celsius and got a total milliamp hour per minute reading off 40.67 which
is actually a bit better than previous iphones i've tested out on my channel 96 after two hours
on the 12 pro max not quite sure what is going on here as i showed multiple times throughout this
test battery optimizations is disabled on this iphone the iphone beside it and all other devices
on the deck here but like i mentioned as well it is pretty hot here in shanghai still and there it
is optimized battery charging is disabled 97 after two hours and 15 minutes is pretty ridiculous
and i have tested it out before at under the 2 hour mark interval pretty similar in terms of
time when compared to the 13 pro max at around an hour and a half or an hour and 45 minutes
and it's just not doing that but it does finally clock off and nick finally gets to take a rest
after two hours and 32 minutes of charging up this big boy over here and it is worth mentioning that
the iphone 13 pro max took 13 minutes to charge up its last 5 whereas the iphone 12 pro max took 42
minutes to charge up the last five percent fifth place over here the iphone 12 pro max zero to 100
using 20 watt charging and 3687 milliamp hour battery doing it in two hours and 32 minutes
one of the longest charging devices ever on my channel fourth place is the iphone 13 pro max no
surprise if you had an hour and 47 minutes has a much larger battery at 4 352 milliamp hours
using the same charging wattage as the 12 pro max and did it quicker the s21 ultra in third place
here with an hour and 36 minutes though i have tested it out before and got just over an hour
massive five thousand milliamp hour battery and 25 watt charging second place here the huawei p50
pro doing it in just under 60 minutes with 66 watt charging and a hundred and 4 million power battery
which is actually pretty impressive but first place very impressive the xiaomi mix for doing
it in 30 minutes with 120 watt charging and pretty decently sized 4500 milliamp hour battery though
i have done the same test and gotten a score of 21 minutes and when comparing these devices
to their previous charge tests on my channel the 12 pro max did it in an hour and 50 minutes last
time i tested it which was around three months ago which is a hell of a lot better than the two hours
and 32 minutes we got today in that same test which actually went against the xperia 1 mark 3
was the s21 ultra which did it in an hour and 14 minutes and since i haven't charged the p50 pro
on my channel yet it is worth comparing it to huawei's last flagship device that being the mate
40 pro with a slightly larger battery but same 66 watt charging doing it in 57 minutes so i guess
you could say it's pretty consistent and lastly the xiaomi mix 4 which is probably the biggest
disappointment over here did it in 21 minutes last time out but you've got to remember that in that
test i actually started it from one to one hundred percent this time we did it from zero to a hundred
percent so i guess xiaomi took nine minutes to go from zero to one percent i'm not too sure i don't
think that actually happened nevertheless like i mentioned throughout the test it was pretty hot
when i decided to charge these devices up but i did make sure to crank the ac up and keep the
ventilation flowing through my household guys i hope that you thoroughly enjoyed watching
this video as much as i did making it this is techneck and i'll catch you in the next one
