Transcripts

what's going on everybody I hope you're

all doing well in this video we're going

to be doing an iPhone 15 Pro Max

charging speed test comparing all the

official Apple iPhone power adapters so

this is going to include the 5 wat 12

watt 20 wat 30 WT and 35 watt power

adapters and we're going to be using the

very same iPhone 15 Pro Max for all five

of these tests and of course to keep

things fair just for this video

optimized battery charging and clean

energy charging are both disabled so the

phone charges straight up to 100% for

all these tests now I highly recommend

that everybody keep optimized battery

charging enabled to help preserve your

iPhone's battery health over time but to

keep things fair for the video I have it

disabled right now but all right we're

going to go ahead and kick off the test

here starting with the 15 Pro Max

completely dead for all tests and we're

going to be checking in at 10 minute

increments and guys it's very important

to note that the iPhone 15 Pro Max's

maximum charging speed caps out around

25 WS so any any charging adapter above

25 WS is going to charge this phone at

the fastest speed possible so in the

context of the Chargers that we're

testing out right now you don't need to

get a charger any higher than the 30 W

charging brick for the reason of

charging speed because the 30 W charging

brick will charge your device at the

fastest speed possible I am including

the 35 W charger in this video as I

decided to include every iPhone charger

that Apple sells but again it's not

going to charge the iPhone 15 Pro Max

any faster than the 30 wat charger now

you can see in this specific test the 35

W charger happens to be a few percentage

points ahead of the 30 W charger but you

should shock that up to random minor

variations that are always going to

occur in tests like this as again the

iPhone 15 Pro Max's maximum charging

speed is 25 watts so if you already own

a 30 W charger there's no need to go out

and buy a higher wattage charger than

that for the reason of charging speed

you can see we have pretty similar

results for everything at 20 watts and

above at this point in the test honestly

my advice is if you already have a 20 W

charger for your iPhone 15 Pro Max I

wouldn't recommend upgrading to a 30 W

charger just for the reason of charging

speed again the 30 W charger is

technically able to charge it a little

bit faster but as you can see here the

charging speed advantage of upgrading

from a 20 wat charger to a 30 W charger

is pretty negligible in the grand scheme

of things so really anything at 20 WS or

above is going to be just fine for the

average person now if you're still using

a 5w or 12 w charger that's a different

story as there's a considerable speed

Advantage going from those up to the 20

W charger as you can see and in addition

to Apple's line of charging adapters

there's a wide variety of other great

charger options and that's where today's

sponsor ug green comes in the ug green

nexe 100 wat charger is a 4-in-1

multi-port charger with three USBC ports

and a usba a port allowing you to charge

four devices at once it's able to charge

a single USBC device at up to 100 WS

meaning you can charge up the MacBook

Air M2 to 55% in less than 30 minutes

the next OD 100 W charger is able to

fast charge a wide variety of devices

including your iPhone your iPad your

laptop your Samsung Galaxy phone and

more thanks to gallium nitride

technology and the foldable plug Design

This 100 W charger is small enough to

fit in the palm of your hand without any

sacrifice in terms of power it also has

Dynamic temperature sensors and an

intelligent PMW chip which adjusts power

outputs to safeguard your devices also

the shell of the charger features a heat

dissipation design to ensure safe

overnight charging leave a link to where

you can check out the ug green nexe 100

W charger in the video description ug

green is running some great Black Friday

deals right now up to 50% off so again

check out the link in the video

description if you're interested big

thanks to you green for sponsoring this

video and continuing with the tests here

in terms of the iPhone chargers that I

see the vast majority of people using in

my day-to-day life it's still the 5w

charger even for people who have the

newer iPhone 12 13 and 14 models that

are capable of much higher wattage

charging and it makes sense as the 5w

charger used to come in the box with

every iPhone up to the iPhone 11 so a

lot of people still have those Chargers

and have been using them since for years

and might not even be aware of how much

faster a 20 W charger can charge their

device but I'm curious to hear what

iPhone charger you guys use so let me

know Down Below in the comments and at

the 1 hour and 50-minute check-in the 20

W and 30 W Chargers charged the 15 Pro

Max to 100% And at the next check-in 10

minutes later the 30 W charger also

charged the 15 Pro Ma Max to 100% so as

you've seen throughout this test pretty

much a negligible difference between all

the power adapters 20 ws and above for

the 15 Pro Max meanwhile the 5w and 12 w

Chargers still have quite a waste to go

both still under the 80% mark it goes

without saying that if you care about

charging your 15 Pro Max quickly the 5w

and 12 w Chargers are not going to come

close to doing that as iPhone batteries

continue to get larger these smaller

power adapters are going to get more and

more obsolete with time but anyway

anyways skipping ahead quite a bit here

at 3 hours and 10 minutes into the test

the 12 w charger finally charges the 15

Pro Max all the way up to 100% meanwhile

the 5w charger still has quite a ways to

go so we're going to skip ahead quite a

lot more all the way to 4 hours and 30

minutes into the test when the 5w

charger finally charges the 15 Pro Max

to 100% as well so here are the final

results in conclusion any 20 W or above

charger is going to be just fine for the

iPhone 15 Pro Max and to charge your

device at close to the fastest rate

possible once again the maximum charging

speed on the 15 Pro Max caps out around

25 watts so if you want to ensure your

phone is charging at the absolute

fastest speed possible the 30 W charger

will do that so there's no need to get a

charger anything higher than 30 Watts

you don't need the 35 watt again

anything 30 WTS or above will charge

your device at the fastest speed

possible which is again going to be

around 25 watts and also since we're

checking in at 10-minute increments

these final times here aren't exact

that's the reason we see 1 hour and 50

minutes for the 20 watt and 35 W

Chargers and 2 hours for the 30 W

charger I'm sure the 30 W charger

probably charged the 15 Pro Max to 100%

probably around you know 1 hour and 51

minutes into the test but again since

the check-ins are only every 10 minutes

it was technically done at the 2 hours

Mark and taking into consideration what

I mentioned earlier about how there's

always going to be some random Vari in

tests like this in combination with the

check-ins being at 10 minutes apart all

the Chargers 20 wats and above performed

very similar in this test and guys that

just about wraps it up for this video

thank you all so much for watching and

of course as always I'll catch you in

the next one peace out
