New MagSafe 25W Charger - Faster Than Expected on Old iPhone

[@VinalAttanayake]

It’s not supplying more power, the old charger also pulls 18.5W to supply 15W to the phone. The old charger didn’t hit 18.5W here because the phone had heat soaked by then.

[@NachtfalkeSC]

Exactly.

[@thebootielover]

It charges my iPhone 10 Xs Max.

[@MovieCaveDave]

And you think Aaron doesn’t or didn’t know that? smh 🤡

[@TVCHLORD]

this is just as bad as this guy running benchmarks after just installing ios updates while the phone is still hot and running things in the background

[@jimscard]

The problem I have with this is that the insertion of the meter between the phone and the power supply invalidates the test. This is because of how USB-C works. USB-C cables are active devices and negotiate charging combinations with the devices attached at each end. In this case, the MagSafe charger cable is negotiating with the meter, and not with the power supply. Also, the test used an Apple dual 35w charger- it’s not clear if that charger is capable of delivering the 30w needed by the fast MagSafe charger to deliver 25W to a supported phone. And, of course, the charger output was negotiated between the charger and the meter. A better test would be to use a power supply such as the Zeus 240w charger I will test with next Friday, which includes its own built in power output display so I will see what it negotiates with the MagSafe. Note also that part of the Qi and MagSafe specs is negotiation between the charger and phone as well.

[@Antt28]

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!

[@thebootielover]

It charges my iPhone 10 Xs Max and my Galaxy S20 Ultra

[@ylswsl2356]

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.

[@jimscard]

@@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.

[@monkeyfish227]

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.

[@nutzeeer]

perhaps apple is grilling old phones to degrade the battery. or the tech is actually better and more efficient. we would need a heat test!

[@NachtfalkeSC]

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.

[@supportyou10]

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.

[@henl6553]

Also forgot to mention that the new MagSafe puck is noticeably slimmer than the old MagSafe puck

[@zollotech]

didn't notice until after oddly. normally I check those things, but didnt notice for sme reason.

[@alienhunter4870]

@@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 😭

[@Carluena]

@@alienhunter4870hey, it will, but it won’t be tight….

[@alienhunter4870]

@henl6553 do you know what the exact depth dimension of the new version is? The older one was 5.5mm. Thanks!

[@dandansfu]

guess cook focus of cost cutting strikes again

[@RudyOMP]

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.

[@carlz28]

Correct. Energy loss through heat is the main culprit.

[@thevacdude]

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.

[@MikeRadioNY]

It was a crime guving and selling limited use cables for years.

[@Braden12]

Glad someone actually tested it. Thanks

[@adamaj74]

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.

[@composimple364]

Just a small correction, 1:51 for iPhone 12 mini it’s up to 12W charging power, not 15W.

[@jonathanleonard9507]

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.

[@marcelleuenberger4648]

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 😅

[@JCourts2k23]

I still use the MagSafe Duo charger and love it

[@monkeyguy80]

I’m SO used to Apple 20w Charger ya! They are quick and decent charging tbh!

[@thebugasproject]

To be honest, I am happy that there is a 2 meter version already.

[@johny1220]

We need to see this test again when the 16 officially comes out lol

[@-SDegirmenci]

6:04 Winding the cable in this way may create a coil effect

[@Fadic4]

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.

[@JohnAliakiozoglou]

Very nice review. Wanted to ask. Is the width of the new charger the same as the old; so as to fit in older stands? Like the nomad stand I own?

[@blastmox]

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

[@JohnAliakiozoglou]

Thanks

[@amill1563]

You know Apple makes a ton of money off all their accessories.

[@JustAPersonWhoComments]

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

[@benjaminstaziker2521]

I still just use my 5w brick and charge over night, really save the battery longevity

[@MRandomClips]

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

[@Tectosaurus]

​@@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.

[@MRandomClips]

@@Tectosaurus its more important to not drop it below 20 and not go above 80 then the speed you charge it

[@bigmaxcc]

😂😂 ☠️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

[@Tectosaurus]

@@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.

[@Skreach666]

I remember hearing when the puck first came out it actually charged iphones at about 18 watts maximum.

Great video Aaron. Keep it up!

[@g.dubyou6263]

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.

[@WhittyPics]

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%

[@zollotech]

Definitely it’s both

[@danielmueller9671]

@@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.

[@jamabo2001]

Please test it out when you get the iPhone 16 pro

[@Slash18622]

The more heat, the faster your battery degrades.

[@marianbadea369]

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!

[@aurorayoru5333]

I love how the Anker Nano 35 w charger is so much smaller then Apples charger

[@nich-nk2cs]

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

[@derekddanderson1]

I was at the Apple Store schooling the store manager about this new chardger tonight lol

[@MindFreak-H]

Hi, do a 2nd video when iphone 16 comes out. Thanks 😄

[@mikewolf5367]

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.

[@Gabri3lRocha]

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.

[@DanielPierce]

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.

[@arvs7356]

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.

[@JoeNasr123]

@@zollotech I personally don’t see the need to generate excess heat and waste when a cable is optimal in every way.

[@zollotech]

It’s more convenient just to set your phone down and let it charge.

[@jimscard]

@@JoeNasr123 Wireless charging in the car is clearly superior because you have less of a risk of getting out, taking your phone and forgetting to unplug it, damaging the cable and possibly the port on the phone as the cable gets yanked as you go out the door. I don’t get people with the “excess heat” bit - the phone regulates the power that the charger supplies, ensuring that heat levels do not exceed design specifications.
