Samsung's graphene batteries, which can charge a phone in 12 minutes, rumored to arrive...

  1. Back in November 2017, it was reported that Samsung’s Advanced Institute of Technology (SAIT) was developing a graphene ball coating. It can be used inside regular lithium-ion cells to increase a battery’s capacity by up to 45 percent and decrease charging times fivefold.

    In addition to holding more capacity and thereby lasting longer, these batteries will be able to fully charge in just 12 minutes. They’re also able to maintain stability at up to 60 degrees centigrade, which should prevent overheating.

    Samsung said last November that the technology was in the early stages of development, but several users on Weibo—the Chinese social media network—claim the company has completed its work and the graphene batteries will appear in phones next year. It's also claimed that as the price of the batteries falls, more companies will use them.

    It seems pretty unlikely that the Galaxy S10 will feature graphene batteries, though mobile head DJ Koh has promised “very significant” changes to the phone’s design. If the technology really does arrive in 2019, we may see it in the Galaxy Note 10 first. These are still just rumors, though, but Samsung definitely is developing the tech, so it will be here at some point in the future.

    Crossing my fingers for new battery tech.

    I'd rather they just allow for swappable batteries again, then I can fully recharge in 30 seconds.

    This would be a game changer and massive advantage over the competition.

    If all these rumors end up being true, the S10 and/or Note 10 are gonna be crazy.

    I would love that too. However, I am tired of all the issues with lithium batteries and ready for something new.

    This wouldn't be explode only make a 2D sketch on your desk if it fails.

    But you know they are going to really bomb you with the price of these batteries, claiming it's all about R&D or any other nonsense they can pull out of their back pockets ......

    This is what the next thing should be. Battery tech needs a serious boost

    Technically, you can swap a battery and have a fully charged device, not fully recharge.
    Realistically speaking, I never fully understood how this is an issue with the current fast charging technology and external battery banks that are lighter and more capable, that also don't require for you to shut down, open and keep an additionally charged battery with an additional cradle or charger or whatever (I'm pretty sure there must be a cradle somewhere and shouldn't be such a hassle to keep 2 batteries of the same device charged, if not it would add to the hassle to charge one, shutdown open swap charge second).

    If you don't mind sacrificing the water resistance of your device, me personally I'd rather my phone be able to take a bath than swap my battery.

    If these are real and the 45-percent increase in capacity is true, this would be a game changer for everything that uses batteries.

    For example, a 300 unit capacity goes to 435 units - so an EV with a current range of 300 km/miles now goes 435 km/miles. (Yes, I know km/miles are not the same thing - I'm pointing out it is a proportional increase regardless of units.) Not to mention the reduction in charge times, however, for an EV, that means a big charge cable with a big fuse and a capable source of electricity. ;)

    I have to wonder whether this is really a hybrid battery/super capacitor since it sounds like they are using some sort of coating on graphene. The smaller the graphene particle, the larger the surface area and thus it can store more charge.

    If true, IMO, it is a big step in the right direction whether or not it is a hybrid battery/super capacitor.

    The trade off is waterproofing and a fancy, cool design. I however loved my LG G4 for it's 30 second recharge. and better yet - when the battery started to degrade it was easy to get a new one.

    New battery tech has a lot more offer than just phones though. Everything from cars to solar storage would benefit.

    Also hoping that the cost to make them is less as well.

    Oh it isn't a long time ago Samsung said they will stop rushing new products on the marked which are still unknows with lots of questions and start focusing on making todays technology better. Don't get me wrong I 100% support companies that do something new & inovative and cross my fingers not to be a failure from such a good phone maker.

    I know this one is closer to the market but for the last ten years I've been hearing that new battery tech is coming and blah blah it will amazing. I am not normally so cynical about tech news but this one is just...same as all the others until it happens.

    To be honest I had the NOKIA with Windows last year or so forgot what series but that damn battery was awesome and what a strong unit! It was that fancy series not the cheap 600s Series. 980 series or something forgot lol.

    To be even more honest as a WinPhone fan and user, you didn't have a Nokia 8xx at all, it was Microsoft Lumia 9xx, possibly a 930 if you had Verizon. Yes, they were awesome four or five years ago. But the chief reason the batteries were awesome (since they were the same ones used in many other phones) was because the WinPhone platform itself was awesome, and didn't run tons of bloatware spytech background tasks at all times like Android or iOS. It was a real operating system. It just had no support from Microsoft, so they ditched it because they didn't care and it wasn't profitable enough. It was the Zune of phones.

    My 925 still works fine; I just don't use it because there's no app support anymore, so you're stuck with what it had three years ago.

    What's draining the batteries in Android are apps that are still running in the background that should shutdown but they don't.

    Force stop them yeah that works but you don't want to keep doing that.
    These batteries still be effected by these same apps draining them too.
    Simple program app, app is open app close and remove itself from memory.
    App hangs on system wasting energy and the battery life goes quick
    Moto Z2 force turbo charger does charge up quicker. With the ideal conditions.
    3.1 amp for Card USB.

    Yeah because this technology if good won't become mainstream...
