Not having to search out the appropriate cable or carry one round with you makes wi-fi charging a handy method of charging your cell gadgets—iPhone, Apple Watch, AirPods and plenty of third-party devices.
There are a number of wi-fi charging requirements and applied sciences. Right here we’ll clarify the key ones—Qi, MagSafe and the newest Qi2. Understanding which is which can aid you to make your charging life extra environment friendly.
Qi2, supported by the iPhone 15 and 16 households at launch and the iPhone 13 and iPhone 14 as of iOS 17.2, guarantees to hurry up wi-fi charging and make chargers cheaper in addition to extra environment friendly. It is rather like MagSafe, which is unsurprising as Apple allowed the Wi-fi Energy Consortium (WPC) to make use of MagSafe as the premise of Qi2.
In brief, Qi2 ought to carry the magnetic advantages of MagSafe to Android, but additionally make third-party iPhone chargers sooner and probably cheaper. Producers usually tend to create new merchandise when the market is bigger (iPhone and Android) and prices ought to come down, too.
We’ve got examined Qi2 chargers vs chargers licensed as MagSafe by Apple, and may verify that 15W Qi2 fees supporting gadgets at an equal velocity to 15W MagSafe, and far sooner than merely MagSafe-compatible 7.5W chargers. Extra particulars of our wi-fi charging velocity assessments under.
Apple has since upgraded it personal MagSafe Charger to assist 25W when charging any of the iPhone 16 fashions. Older iPhones can use this charger however at a 15W most as earlier than.

How does wi-fi charging work?
Wi-fi charging makes use of electromagnetic induction to energy your gadgets. The charging pad and your telephone each embody copper wire coils. Plug the pad into an influence supply and the charger’s coil generates a magnetic discipline. Whenever you place your telephone onto the charging pad, the telephone’s coil converts that magnetic discipline into an electrical present, thus charging the telephone.
First, let’s take a look at the unique Qi, which all iPhones publish iPhone 8 assist.
What’s Qi wi-fi charging?
Qi is a Chinese language phrase meaning “vitality circulate”. Pronounced “chee”, Qi is the fundamental and hottest wi-fi charging normal, launched in 2008 however not seen on an iPhone till 2017’s iPhone 8.
Apple continues to assist the Qi wi-fi charging normal with its most up-to-date iPhones—and the iPhone 13/14/15 fashions are suitable with Qi2, extra on which later.
Which means that iPhones from the iPhone 8 onwards could be positioned on a Qi-compatible charger to begin charging and not using a cable. (After all, the Qi charging pad or stand itself needs to be related by way of a cable to an influence charger.)
Whereas wi-fi charging means much less put on and tear to your gadgets, it isn’t as environment friendly as charging by way of a cable (wired charging) as a number of the vitality is misplaced between the charging pad and the system positioned on it.
Qi customers will know that it’s important to guarantee your system is positioned in precisely the appropriate alignment for quick wi-fi charging to happen.
Place the iPhone on the pad incorrectly and you find yourself both charging far more slowly or by no means.
Many people have dropped a telephone on a Qi charger solely to search out out later that it wasn’t in the appropriate place and so annoyingly by no means began charging—an issue largely solved by Apple’s MagSafe.
Whereas Qi’s most wi-fi cost is 15W, Apple’s iPhone helps solely 7.5W by way of Qi.
Which iPhones use Qi?
Qi charging is constructed into the iPhone 8, X, XR, XS, SE, 11, 12, 13, and 14 households. The iPhone 15 and 16 work with Qi however are rated as Qi2; see later.
What’s MagSafe wi-fi charging?
Apple’s magnetic MagSafe iPhones include a hoop of magnets constructed round its Qi charging coil. In consequence, you may magnetically clamp charging equipment onto the iPhone. Actually, you may magnetically connect non-charging equipment, similar to wallets and mounts, too.
MagSafe—from 2020’s iPhone 12 on—makes lacking the charging pad’s coils a lot much less possible with its ring of magnets rapidly discovering the charging alignment candy spot—on a suitable charger—so you’ll at all times join and fewer vitality is wasted.
Magnetic Energy Profile (MPP) expertise makes use of magnets to completely align the coils of the wi-fi charging transmitter and receiver earlier than transferring energy.
iPhones can work with wi-fi chargers which can be both MagSafe licensed by Apple (“made for MagSafe”) or are suitable with MagSafe—plus much less refined Qi chargers.
Licensed MagSafe chargers can provide as much as 25W to the iPhone, whereas merely MagSafe suitable chargers are restricted to 7.5W, however suitable chargers are normally cheaper. That 25W charging velocity is at the moment restricted to the latest iPhone 16 vary and Apple’s personal MagSafe Charger. iPhones 12/13/14/15 max out at 15W utilizing MagSafe.
(Word that the iPhone 12 mini solely fees at 12W with MagSafe.)
We’ve got examined the finest MagSafe chargers for iPhones and one of the best MagSafe energy banks for iPhones. This evaluations roundup now additionally contains Qi2 chargers as they arrive to market.
Some thicker instances get in the way in which of MagSafe wi-fi charging so be sure that your iPhone’s case is MagSafe suitable—see our roundup of the finest iPhone 15 Circumstances and finest iPhone 16 instances.
Wi-fi charging is nice, nevertheless it’s not as quick as wired charging. For really quick iPhone charging, use a cable related to a minimum of a 20W USB-C charger. For the iPhone 15 and 16, meaning a USB-C to USB-C cable; for older iPhones you’ll want a USB-C to Lightning cable. A USB-A to Lightning cable received’t provide iPhone quick charging. Click on right here for extra iPhone fast-charging suggestions.
Considerably confusingly, MagSafe can also be the title for Apple’s wired-charging normal for its MacBooks—connecting the charging cable to the MacBook’s MagSafe port by way of magnets, which means it isn’t solely simple to attach however, if by chance disconnected, it pops out slightly than dragging your laptop computer to the ground. This model of MagSafe is magnetic and protected and has a charging connection for MacBooks however isn’t wi-fi. We clarify the distinction between MagSafe on Mac and MagSafe on iPhones in our Full information to Apple MagSafe: What’s MagSafe?
Which iPhones use MagSafe?
MagSafe wi-fi charging is constructed into the iPhone 12, 13, 14, 15 and 16 households.
What’s Qi2 wi-fi charging?
Qi2 (“chee too”) is the newest model of the Qi “vitality circulate” wi-fi charging normal.
Famed for its “Not Invented Right here” technique, Apple could be fairly treasured about adopting different technical requirements. It has an extended historical past of rejecting any concept that didn’t originate inside Apple itself.
Nevertheless, fortunately Apple has cooperated with the creation of Qi2 to the extent that in impact it gave the Wi-fi Energy Consortium (WPC) MagSafe to make use of as the premise for Qi2’s Magnetic Energy Profile that defines how the brand new technology Qi works. Apple is a WPC “steering member” and chair of the board of administrators.
So what’s Qi2 and why is it so nice?
Consider Qi2 as not simply MagSafe for Android, however MagSafe advantages for all suitable wi-fi charging merchandise.
Qi2 will imply chargers received’t must be licensed by Apple to assist 15W charging. They need to, nevertheless, meet the technical calls for of the WPC. In brief, a Qi2 charger will ship twice as quick charging as MagSafe-compatible chargers.
As MagSafe certification prices producers a charge to Apple, eradicating this could lead to cheaper chargers that match Apple-certified chargers when it comes to velocity. Qi2 might ultimately overtake MagSafe when it comes to charging velocity, exceeding its 15W most.
Which iPhones use Qi2?
Qi2 wi-fi charging is constructed into the iPhone 15 and 16 household. As of iOS 17.2, Apple introduced the expertise to all iPhone 13 and 14 fashions as nicely.
Whereas Apple hasn’t acknowledged that Qi2 assist will attain the iPhone 12, the primary iPhone to assist MagSafe, Macworld readers have contacted us to say that Qi2 does certainly work with the iPhone 12 following the discharge of iOS 17.4. Examined with the Belkin BoostCharge Professional 2-in-1 Magnetic Wi-fi Charging Pad with Qi2, an iPhone 12 charged as much as 15W with the on-screen animation additionally displayed.
We are going to confirm this growth and replace as quickly as we’ve proved the identical.
Which is finest MagSafe or Qi2?
First, each MagSafe and Qi2 are higher than plain Qi. Owing largely to their magnetic connection, they’re extra environment friendly and positively provide sooner wi-fi charging than Qi.
For all extents and functions, Qi2 appears fairly equivalent to MagSafe so iPhone 13/14/15 customers can select between MagSafe or Qi2 with out concern. iPhone 16 homeowners, nevertheless, ought to look to MagSafe, as Apple’s personal MagSafe Charger can attain charging speeds of 25W when paired with the newest vary of iPhones.
The truth that the iPhone 12 isn’t licensed as Qi2 suitable demonstrates that Qi2 and MagSafe should not equivalent.
Accent maker and shut associate with Apple, Belkin has acknowledged that its upcoming BoostCharge Qi2 chargers “will be capable of cost MagSafe iPhones at 15W”.
Anker claims that its MagGo Qi2 charging gadgets will probably be “suitable with all Apple MagSafe iPhone merchandise”.
Each ought to clamp chargers magnetically to the iPhone in the identical method and permit for 15W wi-fi charging.
Will Qi2 chargers work with MagSafe?
Though technically very comparable, Apple is prone to nonetheless require MagSafe certification for non-Qi2 merchandise to achieve 15W wi-fi charging. Each the charger and the system should be licensed for Qi2 for it to work at 15W, in the identical method as MagSafe. Nevertheless, it’s possible that future MagSafe-certified merchandise will even be licensed for Qi2, and publish iOS 17.2 all iPhones 13/14/15/16 will work natively with Qi2 chargers.
For customers it’s a win-win as Qi2 means sooner wi-fi charging will probably be delivered to extra gadgets and other people. For product entrepreneurs it might be a little bit of a labelling nightmare till all of the chargeable gadgets meet up with the expertise.
Is Qi2 as quick at wi-fi charging as MagSafe?
Because the Wi-fi Energy Consortium used Apple expertise to construct the Qi2 specification, it needs to be true that Qi2 matches MagSafe for velocity. Each can cost at as much as 15W and use the largely identical magnetic attachment tech. Word the 25W charging potential of the Apple MagSafe Charger and iPhone 16.
The primary Qi2 charger we’ve examined and reviewed at Macworld is the Anker MagGo 3-in-1 Wi-fi Charging Station.
We examined its Qi2 wi-fi charging velocity by charging an iPhone 15 Professional all the way in which to a 100% full cost, and taking timings at 30%, 50% and 80%. We did the identical utilizing a Apple’s personal MagSafe Charger and likewise by way of a straight wired USB-C connection.
The quickest method to cost an iPhone is by way of a wired connection: USB-C to Lightning for iPhones older than the iPhone 15, and USB-C to USB-C for the iPhone 15 household. The common wired-charging time in our assessments was 25 minutes to 50%, 55 minutes to 80% and 70 minutes to 100%.
Our wi-fi charging assessments for formally Apple-certified MagSafe chargers (utilizing Apple’s personal Wi-fi Charger) and for Qi2 magnetic wi-fi charging (utilizing the Anker MagGo) had remarkably comparable timings. There was some variance both method but additionally small variations utilizing the identical charger so we’re assured that utilizing these two magentic wi-fi charging applied sciences got here up with the identical primary outcomes on common: 45 minutes to 50%, 90 minutes to 80% and 115 minutes to 100%.
In abstract, then, MagSafe and Qi2 charging at 15W leads to the identical instances and so could be thought of equal—aside from the 25W MagSafe potential of the iPhone 16.
And, once more as anticipated, MagSafe-compatible chargers took twice so long as the 15W chargers: 45 minutes to 30%, and 90 minutes to 50%.
Why does telephone charging velocity decelerate because the battery will get fuller?
Batteries cost slower the fuller they get, particularly within the final 10–20% of charging. The fuller the battery is, the slower it absorbs vitality.
To begin with, a Lithium-Ion battery accepts no matter present it will probably, however because the battery will get nearer to being full it accepts much less present, and so the ability being transferred tapers off.
Think about you had been filling up a glass with water. You can begin with the tap or faucet at full blast, however because the glass will get fuller, it’s important to sluggish the circulate all the way down to keep away from the water spilling over, till ultimately only a trickle of water goes in as you attempt to get it proper as much as the brim.
If the battery didn’t cost this manner and as an alternative crammed up at full blast until reaching 100%, it could get highly regarded and also you’d danger damaging it to the purpose it’d explode!
Slowing down the cost when the battery is getting nearer to full additionally will increase the variety of cost cycles a battery can undergo earlier than it completely loses capability.
Profiting from this, if you should cost rapidly, cease at 80%, use the system for some time after which prime again as much as 80% earlier than the charging velocity begins to sluggish.
When will Qi2 chargers be launched?
Qi2 was formally introduced on the Las Vegas Shopper Electronics Present (CES) present in January 2023. The specs for Qi2 at the moment are accomplished and Qi2-certified chargers at the moment are coming into the market.
Anker’s new MagGo vary features a Qi2 charger, Qi2 energy banks and multi-device Qi2 chargers. ESR has additionally launched Qi2 wi-fi chargers, together with a automobile charger.
