I know, i have zero complaints with how fast my LG G6 charges with a fast charger.
Bought a $9 charge stand for it, plugged it into my fast charger and it's awesome. Almost as nice as wireless charging.
This could be good for laptops and tablets I think.

As someone who has put a lot of research into graphene, I am legitimately excited and sincerely hope Samsung succeeds in finding a cost-effective way to mass-produce graphene batteries. The faster charging is merely a side effect of the many miraculous features of graphene. I personally will not buy an electric (or hybrid) car until one comes with a graphene battery, assuming it doesn't cost as much as a small house. But as soon as one is available, I'm going to be first in line.
Looking at the diagram, it looks like their graphene is very impure, which I find discouraging. It's supposed to be 1-atom thick, so the fact they show it being thicker than the cathode and substrate while also being lumpy isn't a good sign. But, even if it's a third as good as it should be, it's still way better than Li-Ion could ever be.

This is not just about phones...
Imagine the future:
- Self driving cars, trucks, buses, etc.
- Walking robots ( think Atlas or Big Dog )
- Transport pods that go on a pipe (or in it !?)
- Flying machines ( drones ) that could go for hours before charging, they would just land on a charging station 10 minutes and go back in air for more hours
- Other portable/wearable devices that could charge ultra-fast when close enough to a power source
The idea is that at some point we'll simply forget about charging. Devices and vechicles will charge by themselves wirelessly (or by shallow contact) when close to power sources without the user ever having to worry about "plugging them in".
To make this future possible we need new battery tech... which, to be honest, currently it SUCKS. Low capacity/volume or weight, prone to exploding, unstable, doesn't last long...
Fossil fuels have 10 times higher power density than current batteries, no wonder electric cars aren't yet mainstream.

For twenty years its been graphene this and that....
Still not one product.
I'll believe this hype train when they have a WORKING prototype. And its independently confirmed.
Until then it's pure BS Samsung.

Personally I don't care if it's gonna charge 3x, 5x faster comparet to curent Li-Ion or Li-Polymer batteries: all I want is huge improvement regarding battery autonomy, not like now when I need to charge my phone and tablet every 2 days (3 days if I'm not usig them much). Guess I'm a bit spoiled with my old (stolen by unkown idiot some 16 years ago) Nokia 5110 with aftermarket Li-ion 1100mAh (or it was 1300, maybe even 1400) battery: 7 day of average use with hour or two talk-time EVERY SINGLE DAY, and God knows how many times that battery lasted even 10 days, more than once I couldn't find charger for it because couldn't remember where I've put it 7, 8, 9 days ago lol. "Charge and forget" is all I want from batteries used in my mobile devices, but I'm gonna wait a bit till it happens š

About electric cars...*cough* I've seen more than one estimate of the massive increase in nuclear and coal-fired plants world-wide that would have to be built (that do not exist today) to accommodate a universe of electric cars displacing petrol-based vehicles---not to mention that huge mass charging stations would have to be built that are at least as numerous as gas stations are today. The power requirements for 100% electric vehicle use are staggering. 99 out of every 100 people who think that electric cars sound wonderful are people who do not own and use electric cars, presently...;) I'm a big fan of nuclear power, myself, for all of the obvious reasons, but until battery technology improves by at least an order of magnitude you can forget about electric cars--about as likely to proliferate universally as the Jetson's Flying Cars and their cities in the clouds...;) I wouldn't hold my breath waiting on "self-driving" cars, either--right now all that is, is investor bait, and it's not even very "tasty" bait, either. Unless the idea of sharing the road with non-sentient drivers that literally can't discern a meaningful difference between a child and a tree-limb on the road appeals to you...;)

Graphene, the 2 decade old promise.
I do hope Samsung finally pulls this off because we desperately need better batteries.
Could care less about the charge time, although it's nice to have. The capacity is the big deal here, be it for mobile devices or cars, we need better batteries!

Graphene keeps being amazing.

But will it discharge as quickly as any other phone battery? I'd be more interested in a battery that holds charge longer than one that charges quicker.

I'm all for Graphene taking off and revolutionizing everything but at this point it feels like OLED amazing tech that's too expensive and hard to mass produce.

Another one??? Damn! By now we should have at least ten new types of batteries that last 5 to 10 times more than those used til present day. I'll be anxiously waiting for the next one...

regarding batteries... especially with current no-replaceable batteries devices, ie. smartphone, hi-res audio player, bluetooth devices, etc.
i personaly more concern about battery "lifespan"
current li-ion is said have average around 500cycle before the capacity dropping, so depends on user usage it can well last around 2years before user get feel their battery not holding up as long as before
for some people 2years might be enough, as they replacing their phone at that point
but still it will be great if battery lifespan much more longer than current one
those fast charging and capacity will only giving slight improvement if the battery still wearing out fast
even say we can charge within 15mins to full, but if the capacity already drop like more than 50%... we will need to recharge more often either, which means need time for charging
and for some people, the more faster charge time = more usage time, as before those time been used on charging but now as charge more quickly, it means people have more time to use the device = battery wearing out faster

Perhaps some of you forgot the Note 7 problems and worldwide recall ...
Samsung lost billions of $ on that.
It makes sense why they want to avoid such problems FOREVER, by investing money into new battery tech which is safe from the always-potentially-dangerous Li-Ion.
Having faster recharge and more capacity is just a bonus to the consumer... but for Samsung it's about not risking their reputation (and money) again.
