iPhone 8 and iPhone X Will Support Fast Charging, But Only If You Buy a New USB-C Charger (9to5mac.com)
One little detail Apple didn't mention at its event in Cupertino, California yesterday was the fact that the new iPhones will support fast charging. According to the official tech specs page, the new iPhones can recharge up to 50 percent of their battery life in a 30-minute charge. The catch? You have to use a USB-C charger and Lightning cable (sold separately). 9to5Mac reports: iPhone 8 battery life is roughly equivalent to the iPhone 7 and iPhone 7 Plus. On a full charge, expect up to 12 hours of internet usage on iPhone 8 and iPhone X, with up to 13 hours on iPhone 8 Plus. With a 50% quick charge in 30 minutes, you are effectively gaining hours of additional battery life during the day, even if you only plug in for a short period. However, to take advantage of fast-charging, you cannot use the Lightning to USB-A cable that is bundled in the box. Fast charging requires a USB-C to Lightning cable and the USB-C wall charger. More specifically, one of three USB-C wall chargers. Apple sells 29W, 61W and 87W variants of its USB-C power adapters. Prices range from $49 to $79. Apple doesn't break out specific numbers on how each model affects charging times, it's not clear if the cheapest 29W model can achieve the advertised 50% recharge in 30 minutes.
If you can run out a cell phone's charge in the span of one day, you might have bigger problems to tackle than the phone's charging ability. I would imagine that visiting a good clinical psychologist would be a good first step.
I don't respond to AC's.
Ponies!
In other news you have to have the latest shit to make all this magic work. It's all unicorns and turtles.
Of course, the right thing for Apple to do would have been to completely replace the proprietary lightning connectors with the standard USB-C connectors on all of their new device models going forward, but alas, shareholders gotta eat.
My Nexus 6P also can only fast charge on a USB-C charger.
The real news is that the iPhones don't include the cable and fast charger in the box.
Any sufficiently unpopular but cohesive argument is indistinguishable from trolling.
I have a 29W power supply that charges my wife's 7+ noticeably quicker. Same power supply also fast charges the new iPad Pro 12.9.
So basically for modern stuff they're moving towards USB-C, which various Androids (such as Samsung S8) are already using. The only difference is that you also need a proprietary Apple cable to make it work, because someone has to pay for that fancy new 5-billion dollar building.
lucm, indeed.
Holy cow, I'm glad this information is front page news. This is groundbreaking journalism. No clickbait tagline here, no siree. All that's missing is the analysis on how devastating this information will be to the new iPhone's sales.
This should be part of a new series. What cables will next-gen devices come with? Do HP desktops come with regular round power cables, or those weird, flat, 3-wire jobs? And, most importantly, HOW LONG WILL THEY BE? If they include a 3-foot but I need a 4-foot I'll have to go out and buy one!
Seriously, is nothing else going on in tech right now?

Any charging brick that supports the USB PD 2.0 usb power delivery standard will charge a MacBook, new MacBook Pro, or iPhone 8. You don't need to buy a brick from Apple for this.
The only detail to consider is the maximum wattage the brick can put out. That's why Apple sells a larger brick for the MacBook Pro.
Any brick - from any vendor - that can fast-charge a MacBook will fast-charge the iPhone 8 as well. The one I use is the Anker PowerPort+, but there are a number of others.
I've got an HTC one that's several years old, and I can get a 50% charge in 30 minutes with a regular USB cable. I try to keep quiet around iPhone users, though, lest I disturb their superior ego. Now that will really make a mess.
The society for a thought-free internet welcomes you.
so I don't understand why people want faster charging. My first generation iPad is nearly seven years old, and it still lasts over five hours when playing videos or displaying books. I never charge it about 80% or below 20% or ever use a high power USB port. Slow charging is just better.
It's ridiculous that you can't plug your iPhone into a new MacBook or MB pro. The USB c should be standard since the iPhone 7!
The iPhone 8 battery is rumored to perhaps be a s big as 2,700 mAh. Thus assuming no loss in charging, a 2.7 amp 5 volt power supply could charge it in one hour (that is the same amount of power the battery produces in an hour). The 29W power supply produces 5.8 amps at 5 volt (29 / 5 = 5.8). So not counting any loss, the 29W power supply produces enough power to charge the battery to 100% capacity in 28 minutes. So if we assume up to 50% inefficiency during charging, a 29W power supply could still charge the phone to 50% capacity in 30 minutes. If the battery was much larger (like in the plus models), or the charging is less efficient than 50%, a bigger power supply would be needed to charge to 50% in 30 minutes.

Slashdot has missed the two biggest stories in tech this week, both of which happen to be feelgood stories.
1) Senator Ted Cruz (R-Texas) liked an incest-porn video with his Twitter account.
2) Martin Shkreli had his $5 million bail revoked and was put in jail for shitposting. He sent out a message on Facebook offering $5000 if someone would snip a lock of Hillary Clinton's hair. The judge deemed Shkreli a "menace to society". He will sit in jail while awaiting the appeal of his conviction for securities fraud.
You are welcome on my lawn.
We figured this out with the iPad Pro's earlier this year. It's not surprising the iPhones work the same.
You will be hard pressed to find a high quality Android fast charger (latest qc spec) for more than US$ 20.
Indeed Apple is blessed with the most gullible users in the world.
My Moto X supports fast charging, if connected to a charger that supports Qualcomm QC
The phone only came with a basic 5V 700mA charger, so I had to buy a QC compliant charger to use the feature.
If you use a decent gauge regular microUSB cable, you can chain two adapters to plug into a USB-C charge port.
1) USB-A to Micro-USB (c.f. an OTG adapter would work),
2) A Micro-USB to USB-C adapter,
You should get 3.0 Amps @ 5V -- which is about as fast as you can get. Even Qualcomm's QuickCharge doesn't do much more than 15watts, as QC does higher voltages at a lesser amperage for parts of the charging cycle.

(Sorry to the Pixies)
There is another reason why Apple isn't including a charger with the iPhone 8 and X : Watts. And number of different parts.
Usually, the charging limits of a lithium battery are 1C :
e.g.: you can charge a 3'000 mAh battery (like that in iPhone 7 plus) at 3A max.
(that's why usually you can at most charge 50% of capacity in 30min)
Standard tablet charger only go up to 2A, and I think apples "thin as an euro-plug" phone charger are 1A only.
(One of the limiting factor is the way too thin copper wires in the USB cable. Too much resistance for such moderately high current.)
(reminder: thermal loss is only proportional to square of current. It doesn't give a shit about voltage. Standard home appliances cables are usually rated at 10A max).
Various QuickCharge standards (including USB's Official Power Delivery) work by giving the possibility to the device to ask for a higher voltage (9V or 12V or even higher - thus lower current for a given wattage)
That means that the only way to achieve quick charging with iPhone 8 and X is a newer different USB charger that does support USB-PD's higher voltage and wattage.
And now you see where the thing is going : ...but such giant chargers aren't popular with smartphone anymore. (it's not first gen iPod and iPhone era anymore). ...but the fact that it is bundled "free" with an iPhone suddenly decrease the perceived "premium" value of the device that enabled Apple for over-charge at >30$
- that in theory would require Apple to introduce yet another specific "iphone quick-charger", in addition to the 29W to 87W ones (e.g.: something still in the same "europlug" form factor, but with 15W).
- that's yet another different part to take care of (Apple is a company that tries to keep the number of parts low)
- that's openning problem of clueless users who try to charge their high-range USB-C equipped Apple laptop, "because the iPhone charger is USB-C too !" and not understanding why a meagre 15W micro wall-wart can't charge a >85W consuming laptop
- (or worse, the 15W wall wart blows under the load due to sub-optimal protection circuitry)
- alternatively they need to pack at least the 29W variant together with the phone. But!
-
-
In short, it's a nightmare.
And not that many user need to push 1500mAh worth of battery within first 30 minutes anyway.
So...
Let's just neglect to mention the thing altogether.
Continue to pack the phone with a wall wart that is useful for most consumer.
Let power the users (who are in the know) to play with their USB-PD chargers on their own if they want to.
(Best part: now if some iPhone battery blows up, Apple can blame the user of playing with charger which weren't the official packaged-in)

Faster than what ?
Than standard USB wall-wart's max 5V 2A ?
(Meaning that indeed the smartphone manages to ask for 12V 2A using USB Power Delivery protocole - or any other QuickCharge variant)
Or faster than the standard 5V 1A that was packaged with it ?
(Meaning that the smartphone was simply using the standard max 5V 2A that the packaged wall wart couldn't achieve and that the 29W power supply could deliver by default if the device didn't engage in any USB-PD negociations).

what did you expect?
On a long enough timeline, the survival rate for everyone drops to zero.
that sounds like some pretty big reality distortion hype
My Nokia 950 supports USB-C fast charging via a built-in USB-C port, the fast charger came WITH the phone, and I can replace the battery, which is needed because fast charging diminishes the life of the battery.
Apple is still the suxx0r after all these years. Only dummies/sheep buy them.
I am sure on my LG g5 the charger is a standard USB port, not a type C. However the end for the phone is type C. Why on earth could apple not have done something similar?
And the near planet killer CME, X20 that missed us.
Don't worry, it will come back in 10 days, lots of time to charge that iphone.
Just use the cable and charger that ship with your phone
Twinstiq, game news
Because tethered can be confusing.
Apple ditches proprietary cable and will use the standard USB-C cable?
Or is that not anti Apple enough?
The Kruger Dunning explains most post on
If you already have a USB-C charger, you don't have to buy a new one. The headline is incorrect.
gee they require that the charger and cord actually output enough power to charge the battery at that rate?
If Apple had figured out how to charge a battery at a 3A rate with 2A of current I think they would have made i bit bigger deal about it.
Just be thankful you get any ports at all. With them now adding wireless charging I would not be surprised if a future iPhone model has no ports at all.
I had to buy that setup something like a year ago for my wife's iPad. With the charger that came in the box, it discharges faster than it can charge if you use it while plugged in, and seems to only trickle charge if you don't use it while charging. But, with a USB-C charging and a USB-C to lightening cable, it works rather well. It charges her iPhone 7 pretty fast too. Apple really needs to step up it's packed-in power supplies to match the current needs of the equipment they're selling. (Or maybe the point is to get consumers to spend extra money.)
There are many application for iPhone contact management. Among them the iTools 4 is latest and fast software for manage iPhone, iPad and iPod touch. You can use this tool for free of charge. Please visit the official website for downbload and details https://www.itools4.com/
The USB-C charging protocol allows the sink and source to negotiate a higher voltage.
Thank you for trying to correct me with what I've litteraly written, after the next line :
Also note that this is not "USB-C charging protocol". USB-C is merely a connector, used most often for USB 3.1+ but can even be used for USB 2.0.
The protocol is USB Power Delivery (USB-PD) (which supersedes previous protocols like USB Battery Charging Specification) - this is the one that introduces higher voltage negociations, like we've both written.
Also note that USB-PD is only ONE such protocol - it's merely the latest official USB standardization.
Various other vendors protocols such as Qualcom's QuickCharge 2.0 and up also feature the same feat (only QuickCharge 4.0 is officially compatible with USB-PD, though I've read about smartphones (by HTC) running on chipsets (like 625) that are normally designed for QuickCharge 3.0 that can operate with USB-PD - maybe a redesign from the manufacturer, of maybe simple some firmware modifications).
All this isn't linked to any specific type of connector. Both Qualcom's QuickCharge 2.0 and USB-PD can be implemented with any type of USB A and B connector.
(e.g.: Logitech' UE MegaBoom does it over a plain USB-A to micro-USB connection)
This is one of the things that makes USB-C charging better.
Again, this is one of the things that make USB-PD charging better.
It might be implemented in a micro-USB device.
And your USB-C device might only implement strictly USB 2.0
P=V*V/R so the losses in the wire are reduced by 16X, without changing the wire.
Okay, yeah I used another representation of the same law, P = RI^2
(You can convert one from the other simply by using V=RI):
