    I see a lot of confusion over how charging works on this year’s iPhones so I wanted to do a quick breakdown:

    First, know that the iPhones for the past several years have been capable of pretty much two easy charging options. They included a 5W charger (this is the same charger included this year). It is fairly slow but it gets the job done fine for overnight charging. But what many didn’t know is that iPhones have long been capable of charging much faster than the standard charger allows, thanks to tablet chargers. Tablet chargers are typically 10-12W (iPad chargers are currently 10W). iPhones can draw from these faster speeds for a way quicker, nearly doubled charge speed. So if you happen to have a tablet charger and don’t want to spend money for faster charging, the joke’s on you and you’ve had a faster charger than the default speed available already.

    Now, to 2017 we go.

    What’s changed this year are two things: iPhones released this year can charge wirelessly (up to 7.5W via any Qi standard compatible charger) and wired charging can now go up to 18W [based on industry analysis] when using a USB C to Lightning cable (thus being even faster than the 10-12W tablet charger speeds all iPhones were quietly allowed to do before, and about triple the speed of the charger iPhone comes with).

    Now tragically, Apple still is only giving you a standard USB 5W charger and cable in the box. So this means for those looking to max out the charge speeds, you need accessories.

    First, wired Fast Charging. This will allow your charge to hit around 50% in just 30 minutes. To get this, you must own a USB C to Lightning cable - which unlike regular Lightning cables you get with the phone that can be replaced with a certified and affordable third party option if needed, only Apple currently sells the certified USB C to Lightning cable options. Second, you need a USB C wall adapter that delivers 18W or more. Now many people are getting confused because Apple mentions testing the Fast Charging with their own 29W and higher adapters they include with the various MacBooks, but they cleverly avoid disclosing and clarifying that buying their 60W+ chargers aren’t any faster than the 29W charger, and that in fact 29W is not the actual power draw - you only need an 18W+ USB C adapter to max out the 2017 iPhone models’ power draw. Many third party USB C adapters are available, but do note you are looking for models that don’t rely on Quick Charge 2.0/3.0, as that branding is an Android related standard and iPhone simply draws a true USB C power level, called Power Delivery 3.0 (an easy way to know if it has this standard is if the adapter is labeled as compatible with Nintendo Switch - a game console that requires Power Delivery 3.0 from its USB C power adapters as well).

    Next is Wireless - the headliner change to iPhone in the charging realm. First thing to know is that iPhones use the Qi Wireless Charging standard and older iPhones from 2016 or earlier have no built in ability to charge wirelessly at all. You should also know that Apple won’t be selling a wireless charger of their own until 2018, but it has been announced (it will utilize the Qi standard and also has added features that Apple is hoping to help get adapted into the standard). Thankfully, since Qi is a standard and has been well received by many companies before Apple, there are hundreds of good wireless chargers that work with iPhone already on the market. As far as power speed, here’s the gist: iPhone comes out of the box ready for 5W (yes, the same slow speed as the default wired charger in the box), but with a software update this year they will accept a charge of 7.5W and will thus be faster than the default iPhone wired charger, but still slower than using an iPad charger or the new even faster option of USB C Fast Charging. So for that reason, those looking to take advantage of wireless charging should look for chargers capable of 7.5W or greater (while a couple of third party wireless chargers are available on the Apple Store site at this exact speed, it is unusual). A downside here, however, is that Apple is not using the fastest wireless speeds supported by Qi on smartphones and would likely make next year’s iPhones charge faster wirelessly since this year’s are kind of behind the curve already. For that reason, you will see many third party chargers are capable of 10-15W. I’d recommend those looking to be able to get the most out of wireless beyond just this year to seek out a wireless charger capable of 10W or greater, as it is highly likely that as early as next year, iPhones will come with the capability to receive 10W or higher from Qi chargers.

    Somewhat annoyingly, USB C and Lightning are new to iPhone and not really intersecting with wireless options yet on the larger market, so unless you wait, you won’t see many Qi chargers use a Lightning cable or USB C or both prevalently, if at all. This should change now that iPhone has joined the race, but it makes those who want both fast wired and wireless charger in their homes a little stuck buying multiple types of cables.

    So those are the basics. Many of these products can be found on the Apple Store now. Here are some links, but shop around for deals:

    It will be interesting to see how many watts the yet-to-be-released AirPower pad will provide; 5, 7.5, or 10W. Hopefully at least 7.5 and then the AirPower 2 will give us 10 or 15W.

    or plug it into your monitor that has a usb 3 fast charge port.

    The 60w charger is for pass through charging and power. 29w will crap out.

    I'm guessing I'm slow here but just in case you are too read on... Was glad to hear that I could "fast charge" my iPhone X with my USBc charger from my MacBook. Unloaded the money for a USBc >Lightening cable and looked forward to it's arrival. Then I remembered I had a USBc to USB adapter with the MacBook so can use that with a standard iPhone cable instead of paying €29 for a new one. Testing now charging my 6+ and it seems to be working fine (and faster)

    Interesting and helpful read, thank you.
    I am looking to purchased this QI wireless charger from BlitzWolf for my iPhone X
    https://www.blitzwolf.com/BlitzWolf...Charger-for-Samsung-S7-EdgeS6-Edge-p-137.html

    But I still am not 100% how I will be able to get the 7.5w fast charge speed when/if Apple have a iOS update to allow up to 7.5w wireless charging.
    When the update happens, to be able to get the 7.5w charge speeds what would I need to buy?
    Obviously the 5w Apple included wall adapter will not work. How about the 12w wall adapter that I got with my iPad Pro will that allow for 7.5w with this wireless charger?
    Or would I need to get a Samsung “adaptive fast charger”

    I would like to use the wireless charging that the iPhone x offers, however I also want to future proof and ensure that I can get the fast 7.5w charging when Apple allows it for the X

    If you are able to help, that would be great
    Thanks.

    Thank you for this.. I’ll have to reread it but I’ve been trying to understand it all. I want to figure out what to shop for so this should help.
    Since I’m only looking at wired chargers.. would it be worth the money to get a 18w charger/cable/adapter considering I’m using my iPad charger now? It wouldn’t be as convenient two have two different ones, but if it’s a lot faster and I find a Black Friday sale, well would be good to know

    only the apple usb-c to lightning cable will provide fast charge. using adapters and third party usb-c to lightning cables wont work

    Do I also need an Apple brand QC 3.0 power adapter, or will third party power adapters work?

    Apple doesn’t support QC (Quick Charge). You can use third party chargers but need to look out for ones that say they support USB C Power Delivery (3.0, which is the same kind required for Nintendo Switch)

    Exactly. This is where I actually applaud Apple as they adopted the universal USB PD spec. Many manufacturers have used their own proprietary or even Qualcomm’s fast/quick charging but Google and Apple are both on the same page with USB PD, although Apple is still holding on to lightning.

    So.. to conclude - if I have a 10W or 12W Apple adapter and pair it with any Qi pad - I will get the 7.5V 'fast' charge when Apple switch it on. Is there any advantage to using an 18W adapter at all if it's just for the Qi Pad?

    The question is, will the iPhone accept a 9v change?

    I have the Samsung convertible wireless fast charger. The one that they give with the free promo for the note 8. It’s good but real slow with the X. Is there a wiresless charger that charges the iPhone X any faster?

    we don't know yet. the mophie and belkin apple sells are supposed to support it.

    The 7.5 may be something that will only work on chargers that apple certifies.

    So if the charger can output up to 10w and the power is the 12w iPad adapter - it might not do 7.5w. Surely this is the phone controlling the amount of charge rather than the charger.
