The iPhone gets 15W, but the Charger needs more than 15W to give out that amount. That’s normal. You have to take some losses into account. This Charger does not charge the iPhone 15 more quickly.
I don’t think the new charger is actually charging the older phone at greater than 15W. It’s likely that in order to push 15W of wireless charging it takes ~18.5W of line power because of losses due to wireless charging (and why you need a charging brick 5W more than the MagSafe charging speed) The older charger possibly wasn’t getting up to full speed for some reason or another. Still great to see someone testing it out though!
It is so annoying, because apparently you need to buy these new MagSafe chargers if you want to charge iPhone 16 pro series at 25w speed, but I bought anker cube that is like $100+. At least they did not make a newer Apple Watch charger for faster speed.
@@Antt28It’s not. The actual phonecharger connection is controlled by the phone - which requests the amount of power it wants the charging coil to push. The iPhone 15 MagSafe can only request up to 15W anyway. The new MagSafe charger can supply up to 25W to any phone that is capable of requesting it. Current Qi2 devices are also only able to negotiate up to 15W.
I’m surprised it’s not widely known that wireless have energy loss. The heat on the coil comes from energy and it’s “loss” since it doesn’t goes into the battery.
Just because the charger is pulling 18W doesn’t mean the phone is charging 15W, in fact I’m 100% sure it isn’t. Wireless charging is very inefficient compared to just plugging the phone in.
Is it worse to charge your iPhone with MagSafe charger rather than cable. I’ve always used a cable but considering getting a MagSafe stand as I can limit to 80% and it gives me standby mode
It’s about time they made all their charging cables braided. Cables in general, hopefully no more frayed chargers. I think over almost 8 years, I went through three chargers for my 2015 MacBook Air at about $80 apiece.
@@zollotech Is it significantly slimmer than the previous one? Can you reply with the difference in thickness? I am starting to think my MagSafe puck stand won’t work with the new charger 😭
You can’t use the power consumption of the wireless charger as the input to the phone. A lot of that is dissipated as heat. Ankers Qi2 charger requires 20 watts but only charges the iPhones at 15 watts.
It is probably not just temp but also how much charge it has. I notice my watch will charge pretty quickly to 90% and it will really slow down to charge the last 10%
@@zollotechdefinitely, LiIon batteries will only charge at max speed under 30% usually to not stress the battery too much. Of course this is in the hands of the manufacturer to decide.
Glad they finally got a bump in the wireless speed. By the time iphone 17 comes out, im sure brands like ESR will have a good cooling solution for this new charging speed.
If you account for the efficiency and losses, the USB-C side will draw more than actually arrives at the phone. Estimated 80% efficiency (stretching it a lot, usually worse) at 15W is an additional 3W = 18W power draw What I find more interesting though is the comparison with the old model, actually using much less than the 15W 😅
Just like a lot of other comments are saying... The speed you measure on the wire is not the speed that goes into the phone since there's a lot of power loss with wireless charging. Wireless charging is still a very bad way to charge your phone because of the power loss and more importantly the high heat generated. It will degrade the battery much faster and take longer. And it's not even convenient since you still need to pull on it to detach the magnet!
Thanks that was very helpful I'm not a fan of braided cable at all I will pay more for a non braided cable if it gets a little dirty I can wipe it off braided just continues to get dirtier Thanks for all the work you put in your videos
I would imagine that because they only sell the new one you are probably ok to use it on older phones. If there was a thermal issue they would only list the new one as compatible with the 16 series.
True but for myself I don’t mind the extra convenience of not having to plug my phone in every time if it means sacrifice battery longevity. I don’t mind spending the $60 to replace the battery every two years. Now I don’t have the headache of worrying about battery longevity and turning off a bunch of background settings.
The new MagSafe charging speed on the phone is enabled by denser charging coils in the iPhone 16 line, so obviously it won't be the same for the older models.
i have lots of people claim this but my battery percentage is much better then them after a year and i charge at the max 27w on my 15 pm with a 67w brick
@@MRandomClips it varies, you probably just use your phone a lot less than they do. It's proven that heat destroys batteries, and charging with a 5W brick doesn't generate any. There's just no reason to fast charge overnight.
😂😂 ☠️I laugh “5w brick” what is 2012 you pay for expensive phone to charge it slow F that if you can pay for it you can get battery replacement which not expensive
@@bigmaxcc there’s literally no point in fast charging overnight, you’re sleeping lol. And some people keep their phones 3-4 years. The quickest I could get a battery replacement is 2 weeks, I can’t go without a phone that long so keeping my battery healthy is a must.
Aaron, I’m hearing that the new phones, Pro Max, charge at 45 watts. What Apple is available for the new phone? I’m only seeing a USB cord is coming in the box.
You left the screen on?? If so, this video is meaningless because the screen being on would slow down the charge rate by a significant factor and it would also create a lot of heat which would further slow the charger down.
Aaron do you think the iPhone 15 Pro max will be able to handle 18.1 with AI without having the new improved thermals? another overheat from software issue?
There is a claim that all iPhone 16 models can charge at an initial rate of 45 watts on a wired USB Type C connection. Try this with Apple's 67 watt adapter and see if that really does happen.
My previous MagSafe charger that I had been using since I got my 13 pro split at the end so I snagged the new one! Can’t wait to finally have one braided so it doesn’t look yellowed and gross lol
If magsafe charges everything in ecosystem(watch, buds) then only it makes sense, otherwise there are better safe alternatives. This phone doesn’t provide reverse charging, then also this would have been recommended.
hi aaron, may i know the model number of the new magsafe charger? the apple store gave me A2140 model and they assure me it's latest model. The cable is not braided so thinking they gave me old model. :(
Because of the new regulations in China iPhone 16 series will only charge at 7.5w with MagSafe and the new Apple Watch 10 won’t get fast charge too,what a pity
The iPhone gets 15W, but the Charger needs more than 15W to give out that amount. That’s normal. You have to take some losses into account. This Charger does not charge the iPhone 15 more quickly.
Exactly. Maybe if it was wired then the power loss would have been a lot less. Then it would be closer to the actual rated value.

Right. Braided nylon should have been the standard years ago. Rubber cables shouldn't even be made, let alone sold.
This is very helpful, thanks. And thank you for switching the temperature units from Fahrenheit to Celsius 🙂
Also forgot to mention that the new MagSafe puck is noticeably slimmer than the old MagSafe puck

Ankers Qi2 charger requires 20 watts but only charges the iPhones at 15 watts.
Just a small correction, 1:51 for iPhone 12 mini it’s up to 12W charging power, not 15W.
Thank you for checking the temperatures!
I’m SO used to Apple 20w Charger ya! They are quick and decent charging tbh!
Thank you. Outstanding comparison
Thank you for showing us 😊 0:43
Adapter supplies ~20W to charge the battery at ~15W. The reason for the higher draw are efficiency loses due to heat.
Great video Aaron. Keep it up!
Great Video!
Thanks for the test Aaron! I'm pretty sure the same charging watts is applied to older iPhone models and not greater when ur on the iPhone 16
Very informative.. gona need a part 2 when you have the iPhone 16
Hi! What about thermals difference when charging with 15w old charger? Is 16 pro max significantly cooler?

on my 16 pro max with the new MagSafe puck and 30w apple charger its going so slow not 25w, usb c is much faster, whats happening
The new 25watts is likely a perks in power electronics, allowing higher switch speed, thus, higher induction efficiency.

I would imagine that because they only sell the new one you are probably ok to use it on older phones. If there was a thermal issue they would only list the new one as compatible with the 16 series.
The fact that these phones get hot while wirelessly charging is one of the reasons why I don’t wirelessly charge. Batteries don’t like heat.

I love how the Anker Nano 35 w charger is so much smaller then Apples charger
That’s nice. I will stick with my old one. For some reason my 15 PM doesn’t do optimized charging. Called apple but they were no help.
The magsafe produced in Europe is marked with 15V3A. Does it mean that it can achieve higher charging power in subsequent software updates?
I am still thinking about buying this new one for my bedroom to charge for my old 2 year’s old iPhone 12 👍🏻
Do you need to force the new braided model to get 25w MagSafe? Or will the older model still work if you were to buy an iPhone 16
Will work at 15w. You wouldn't need more anyway because of heat.

It is the same width but it is thinner tho so I am not sure than it will go in the stand you bought
