Quick charging smartphones

Everything rumored about the new iPhone points toward it having a quick charging ability similar to the leaf. It has a metal back to better dissipate heat and a new connector capable of carrying the power the new iPad will need when it's upgraded to quick charging later. The power output of an iPad charger also matches with the power requirements for quick charging an iPhone. It makes me wonder if Apple engineers got any inspiration from the leaf.

Clearly you are unaware of the fact that Apple never copies anything from anyone! Not even Xerox Parc... :lol:

heat from charging is minimal compared to heat caused by processor and 1 or 2 rogue apps.

Not if it charges in 5 minutes.

Ah ha. Finally justified. The new iPhone 6, which has only a 20% larger battery, can charge using an iPad charger at 12 watts instead of 5.

On this subject, I was unaware of true quick charging phones until it was mentioned briefly on the TWiT (http://twit.tv/show/this-week-in-tech" onclick="window.open(this.href);return false podcast.

They're referring to this:

Some phones/phablets come w/the an AC adapter to allow this whereas it's optional on some others. http://www.motorola.com/us/accessories-batteries-chargers/Motorola-Turbo-Charger/motorola-turbo-charger-pdp.html" onclick="window.open(this.href);return false; is one of them.

I sometimes use my iPad charger on my iPhone, which makes it charge pretty quick. I don't do it a lot though, because I don't want to stress my phone battery too often.

Why would you need to quick charge your phone? Just plug it in during the day no issue.

Have never forgotten to charge my car, but my phone... Or at least I've picked it up in the morning thinking I had more charge than I did, so needed to get a bit more in there pretty quickly before I had to leave for work (though I can also charge in the car, but rarely do).

Real smartphones have been charging at 2.1A+ for a while now. Apple is, as usual, slow to the party and loud.

Not all of us sit at a desk with ready power available. Also some locations due to a poor or blocked signal can eat up the battery in no time. I keep a charger available for my crew to use and its slow to the point that sometimes its a battle over "plug time"

That "metal" back may not be metal - that would interfere with cellphone, WiFi, and Bluetooth communications.

Phone manufactures (including Apple) were motivated to do away with dedicated mobile device chargers to save money. The most common power source eventually became USB (500mA at 5V), but the power is limited. Now, every device can charge from any USB port, but many devices can accept much greater power, if it is available. Hence, high power USB chargers (2000mA at 5V).

The only thing Apply did was to provide a high power charger the iPhone would accept as a licensed Apple product. If it wasn't Apple licensed, charging was intentionally limited to 500mA. The new connector probably forces users to purchase replacement chargers that worked with older Apple products.

It's marketing, and another way to extract greater funding from supporters.

Welcome to customer lock-in hell.

Yep, my Galaxy S5 charges at 2.1 amps...

I recently got a Samsung Note 4 and it has not only high amperage 5V charging, but a new quick charging standard called "quick charge 2.0" that uses 9V at 1.2 Amps over the usb cable. Obviously there is some sort of communications to verify nothing else is connected besides the phone to prevent other devices from being blown up. My phone charges from low-ish state to 80% in about 30 minutes. It's pretty sweet!

There was an ad from 4chan about wavecharging OS8 iphones in a microwave . I suppose it might charge the battery but with destroyed electronics a charged battery isn't very useful. But yes there is a demand for fast charging - even in phones and EV's. I like to be able to swap the battery out instead of fast charging it. But swapping out the battery in an iPhone is not trivial nor was the business model for "A Better Place" successful.

Yep, it's listed at https://www.qualcomm.com/news/snapdragon/2014/06/04/quick-charge-20-has-arrived" onclick="window.open(this.href);return false; that I mentioned earlier.

I'm waiting for a CHAdeMO adapter for my Galaxy S5.
