[@uberacx]

This is the biggest misconception of battery charging. Google it.

[@bourbon.36]

It most definitely is. Heat and fast charging are the two most destructive things for a battery. I upgrade every year and the 5 watt charger would only drop 1-3% over a year. Ever since I started using the 20 watt adapter, I lose up to 10% over a year, and that is with optimized charging turned on.

[@twanwick85]

It is but not necessarily battery health will go down regardless but more videos using the five watt make it the same temperature as the 12 or 20 wt

[@NoWayJose0_0]

20w will produce the same battery life it’s minimal difference. The only thing you can really do is not overuse the phone all the time or turn on the charge until 80% setting

[@millenwagon]

@@NoWayJose0_0 my iPhone 12 battery health went down significantly faster when I used the 20 watt charger, just going on my personal experience but results may vary for other people

[@dylanwhite6539]

MagSafe actually draws up to 30w from the power adapter and using the 20w adapter does limit it. However not by much since the thermal limits kick in. The ESR MagSafe with cryoboost is actually the coolest method of charging I’ve found. Even cooler than any wired option (aside from maybe sub 12w)

[@spacecadet2172]

Macworld did a similar test, and they were able to charge the iPhone 15 Pro via Magsafe with the Apple 20W adapter to 50% 45 mins, 80% in 1:30hrs and full in 1:55hrs. His took over FOUR hours to fully charge. So seems there can be a lot of variability (Macworld did several tests and got relatively consistent results). They also compared MagSafe with Qi2 and found them to be similar in charging performance.

[@MobilAvenue_]

I’m not really too fussed on charging speed, I put my phone on the MagSafe charger overnight so as long as it’s charged by morning I’m good

The heat generated by wireless charging will shorten the battery life measurably quicker than using wired charging

[@MobilAvenue_]

@@CrisCheese_ I don’t think the one I have is that powerful also charges my Apple Watch at the same time

[@CrisCheese_]

@@MobilAvenue_ No matter the power, wireless charging is always (because physics) more inefficient than wired charging whereas inefficiency means generating more heat and more heat = more battery degradation

[@MobilAvenue_]

@@CrisCheese_ I understand that wireless charging is more inefficient. I think after one year of wireless charging on my iPhone 14 pro it was down to 94% capacity. I’ve just upgraded to the 15 pro so I imagine it would be the same. I also have AppleCare which will cover the battery if it loses more than 20% capacity.

[@CrisCheese_]

@@lnielsen9866 You do know the battery health displayed in the system settings is inaccurate, right? For some reason apple uses a non industry wide algorithm to calculate the battery capacity displayed in settings. To get find out the real amount u gotta save some diagnostic files off of ur iphone to a pc and use a 3rd party tool to display them properly, where you'll find the actual percentage

[@Zomboy4313]

Since the iPhone 15 pro charges at a max of 27 watts you should put lower wattage chargers than 20w to see a bigger difference. Plus iPhones pull more watts from the charger when it’s in use. My iPhone SE2 normally draws about 10W when I’m not using it but running benchmarks can get it to pull 20W

[@RirtyDascal]

My 30 watt MacBook Air charging block paired with the cable that was in the 15 Pro Max box seem to charge my phone from 20 to 80 percent in a little over 30 minutes. It seems super fast compared to a XR or even my Note 20 Ultra. I'm probably gonna end up timing the next charge cycle out of sheer curiosity. I might eventually grab the 35 watt 2 port, just to more conveniently charge two devices at once when I have to. Thanks for the video brotherman.

[@AnkushAroraAnky]

Correct, my macbook charger is charging my iphone the same way

[@bertellihandpan]

dont u think this might ruin the battery mid to long term? I have a 30w and im considering buying a 20w

[@indianrailways-southernrai4427]

I heard it will destroy the phone

[@Dinara1up]

Have the Note 20 Ultra as well and the 35 watt MacBook dual output charger. The 15P definitely chargers really fast with the MacBook charger. But don't worry about it destroying your battery guys, the 15P is only capable of pulling 9v and 3A during charging using USB C PD, that's 27 Watts max. So regardless of the fact that you use a 100 watt or 30 watt brick, the iPhone will only charge at 27 Watts max.😊 I've decided to just use my N20U's 25 watt charger.

[@0xroxyyyy]

​@@bertellihandpan Nope, Apple mentioned about this and we can use it.

[@themightyant.]

It charges from zero to 80% in around 55 minutes, that is fine for most people. It slows down significantly after that.

[@AngeAlexiel]

one thing to note is that it is a brand new 3nm chip , and irecall my 14 PM could go as high as 29 watts instead of 27 watts on the 13 PM , since I got on day one the 15 PM , I've noticed it charges faster on an anker nano 65 watts. usually the phone if dead is near 60% after 35 min. and it take 1h35 to 1h45 to change it completely. ( I leave Optimized charging on but it's not yet really on ) ... needs to learn my routine , it can take weeks.... but I pretty sure this 3nm chip is extremely powerful , and some had overheating issues with some apps until 17.0.3 so my guess is that Apple will slowly increase the speed of the charge in the 17.2 ou 17.3 beta , like they did with the 14 PM from 27 to 29 watts last year... Apple still needs ( and mostly 3rd party devs ) to learn how to deal with this new chip and optimize it . I'm sure we will noticed imrprovements. I'm happy that they can charge up to 50% in less than 30 min. that's the most important, but we wish it could be even faster for sure.

I have few chargers at home. 5w of course. A 10w comes with my 2 gen iPad. A 12w adaptor from my 2nd gen iPad Pro. A 20w from my new iPad (10 gen). And a 35w dual output charging comes with my new MacBook Air. I have an iPhone 13 and a 14 Plus. 5w charge very slow of course. The 10w & 12w both charge quite a bit faster, cutting almost 1/3 time to charge to full, especially the 12w I noticed. Now with 20w it cut the time in half. I then try the 35w, it seems to charging even faster but not by much compare with the 20w. So I believe there is just so much maximum limit of charge current going into the phones. 20w is the ultimate charger.

The 1 meter woven cable that comes with the iPhone 15 series tops out at 60 watts, so no, he’s not limited by the cables. Also, as demonstrated in the video, as well as over at Chargerlabs, the iPhone 15 Pro accepts up to 20 watts but not above that.

[@paultmane]

Great comparison, I appreciate the complete look of time/temperature/and wattage. Thanks! Oh, btw, regarding magsafe overnight, as I typically have my phone connected around 7-8 hours overnight, what do u think about using a lower wattage power adapter, say the apple 12w? As I don't need it to be ready in 4h, maybe the slower 12w would be better for temps....

[@mattd8670]

Does MagSafe really help your battery, especially with how hot it gets?

[@Johnnyiswhere]

Yes it does. The heat is centralized, and smart enough to know exactly how to charge your phone

[@chaseyoung2778]

No it doesn’t. Magsafe being the hottest means it will affect your battery health.

[@javianjohnson8746]

I've been thinking and I wonder if there's a correlation between higher watt chargers and iPhone battery degradation? Especially with the iPhone 14 Pro battery capacity drainage controversy my guess would be that chargers that pump high velocities of charge into the battery in a shorter time frame might contribute to the batteries heating up quicker and killing overall capacity

[@helloyes2288]

Could just as easily be that the difference in wattage has only a slight impact and that the battery degrades at more or less the same rate for the entire time you're charging it, meaning wireless charging or low watt chargers would be the worst.

[@iAmThatOneDuck]

While there certainly might be a correlation, I think the indirect correlation might be more important: the faster the charger/charging, the more tempted someone's going to be to either drain their battery a lot and quick charge it full right before heading out to a day of usage, which is very heavy on a phone battery I'd expect, since these perform and charge the most effective and efficient between 40 and 80 (hence why charging is halted at 80% on a lot of phones these days). Going from lets say 20 to 100 to 20 every 24 hours, I can't imagine it not being heavy on a battery.

[@_..-...--.-.-.-..-]

Simply put: higher charging power produces more heat, and heat is what kills the batteries

[@tioswift3676]

Yes. More power equals more heat. Heat kills batteries. This is why my iPhone 8 Plus, original battery is still at 93% health.

[@Ohkeh640]

Whaaaaat? Nah if u use a 20watt plug it’ll charge at 20 watt All the cords for iPhone phones are the same The bricks are the wattage

[@raw_pc]

Magsafe may be slower but in the long run it will save your iPhone's battery life more. There's no point in supercharging your phone every single time because it just breaks the battery health exponentially faster. It's not Apple's fault or Samsung's or any other brands, it's just physics. Use Optimised Battery Charging option and you'll enjoy your battery for longer.

[@Ryuzaki625]

Does the ligthning to usbA cable supports rapid charge with a third parties charger?

[@MarcinPalka]

I suspect that the subtle differneces between the 20, 30 and 35w are more due to the apps and connectivity draining the batteries at slightly different levels during the test.

[@paultasker7788]

The 30 watt was slower because it took longer to start charging. Possibly because that iPhone battery was more drained.

[@maliknaasan6113]

you should add a 10 watt and 5 watt charger too. some people just want to charge it over night without it heating up at all.

[@juenixthelostboy]

So I don't know how well informed you are about the iPhone 15, but the reason why you have pretty much the same charging time for the 20w, 30w and 35w is because the iPhone 15 only supports 20w. This means that even if you were to use a 120w power supply, the iPhone would still need about 1 hour and 45 minutes to be fully charged, it doesn't make any difference, even the iPhone 15 pro max only supports 30w, which is quite little for this time, but you know Apple

[@Zaedas1987]

But you know the Iphone 15 have only two cameras and this phones what he use have 3. That means he use the 15 Pro phones

[@Penly123]

Since the iP 14 series, Apple has started using batteries produced by another company in China, leading to a decline in battery quality compared to the iP 13 series and earlier. The batteries tend to degrade faster, and the overall battery life is significantly shorter than in previous generations. Apple has opted for some components of lower quality to reduce costs and maximize profits.

its wrong, since the iphone can max charge with 27 watts and you will not get that with a 20 watt charger, simple as that. However this will not give you much of an advantage since the iphone steps down in charging speed pretty fast. I guess maybe 10 minutes advantage in the end.
