Charge Your Cellphone’s Battery In Just 10 Minutes? We Hope So.

A company over in Japan is getting closer to releasing a battery jacket which allows a device’s battery to take in much more power at a faster rate, which in turn, allows for batteries to become fully charged in just 10 minutes. This is so long overdue. Battery life always seems like a selling point for some devices, but if you can fully charge your device in just 10 minutes, I can’t see that being an issue any longer.

Everyone else hoping this comes to fruition as soon as possible?

    its a cool concept. But thats also dumb. I used to race RC cars when I was young. Simple, you raise the amps, the power to the phone and the speed of the charge is faster, but you lose battery life both in the short and the long run. So @ .5 amps that phone may be for 8-11hrs. but at @ 5amps then that phone that charges in 5 mins will prolly last for only 2-4 hours tops… unless they are able to create a thinner batter with higher capacity…. We’ll just have to see

  • I not to mention my guys were studying the great secrets and techniques found on the website while instantly came up with a terrible suspicion I had not expressed respect to the website owner for those techniques. All the young men were for this reason glad to see them and have in effect without a doubt been using them. Appreciation for turning out to be well considerate and then for making a choice on varieties of superb subject areas most people are really needing to learn about. Our honest regret for not saying thanks to earlier.

  • I wanted to create you the tiny remark just to thank you very much over again with your stunning information you have contributed on this website. It was so unbelievably generous with you to offer extensively what exactly a lot of folks would have advertised for an e-book in order to make some profit for their own end, even more so given that you could possibly have tried it in the event you wanted. The good ideas likewise worked as a good way to be certain that other people online have similar zeal really like my personal own to understand a great deal more regarding this issue. I’m sure there are some more fun sessions up front for people who discover your blog post.

    “A company over Japan” makes it sound like it’s some startup. This is being done by NTT DoCoMo – you know, roughly the Japanese equivalent of Verizon.

  • Sounds great! Now just do this for a electric car and I’ll finally buy one..

  • Foxtrot21alpha

    I can already see ppl batteries exploding when this releases lol

  • thê randy

    Is this going to be like Chinese food though??? You know, you eat it and then about 20 minutes later you are hungry again…like you charge your phone..it looks full…but 2 levels of Angry Birds later you have to recharge it again? 

  • Billy Jenkins

    I hope someday they make a battery jacket for android phones that can charge your phone quickly and wirelessly and once its fully charged the phone should remain charged using solar powered technology. which would basically give the phone an infinite amount of power with only having to charge the phone maybe once a year.

    Why are people saying they would rather have their phones charging for 6-8 hours and have it last days of moderate usage? How about having it charging for 10 minutes and have it last for days of moderate usage.

  • Tony Allen

    This isn’t a battery tech fix, this is a lame band-aid to get us to buy more crap. 

    We need better batteries, in conjuction with software management to make more efficient use of said batteries. 

  • I leave my phone plugged in at night to charge, so having it charge in 10 minutes would not be worth it. I would rather have it charge for 6 hours and last 2 days. 

  • And why don’t you beam me over some fries while you’re at it!

  • hkklife

    This is all well and good…however, I cannot get over the lamenes of Apple’s event today.  iOS5 and Siri look awesome, as does the iPhone 4S’ camera but a 3.5″ screen is SOOOOOO 2007, as is the lack of any kind of 4G connectivity.  I hope Samsung and Google knock it out of the park with the NP and ICS announcement next week! 

  • yeah this wont make your battery die quicker no.

    sheesh cell batteries dont last over 2-3 years as it is much less “lets supercharge them”.

    PS – yes i use phones longer than the 4 month average most people nowadays do.

  • I’m just commenting to make you understand what a useful encounter my friend’s child developed going through your webblog. She realized plenty of things, which include what it’s like to have a great teaching mindset to have many others completely understand various tricky matters. You actually did more than people’s expected results. Thanks for displaying these precious, dependable, informative and in addition cool thoughts on that topic to Julie.

  • Droidmaninblack

    I thought that charging current batteries faster than 1X capacity causes overall battery life to suffer. I don’t care how fast it charges if I have to replace a battery more frequently than once every 2 years.

    • KevinC

      you thought wrong.

      • Tony Allen

        No, I believe he’s pretty spot on. This kind of charge/discharge/charge thing can’t be good for these batteries.

    • Anonymous

      I agree. No way you can charge a standard lithium-ion battery in 10 minutes without some kind of degradation to the battery. I wonder how hot that battery must get during a 10 minute charge. Heat is detrimental to l-ion batteries.

  • Bunie

    Hasnt this always been possible but was just against FCC Regulations?

  • RonsterWVU

    Why would you site Phandroid, when the video, and image are both from Engadget?
    Why not just site Engadget, Phandroid did…. 

    • Anonymous

      Because they didn’t get it from Engadget. Maybe it should say Phandroid via Engadget but it doesn’t and it’s not that big a deal.

    • Billyrouth2000

      Let’s see because it’s his website and he can do as he wants.

      why are you worried about it?

  • Anonymous

    I see no possibility of an explosion.

  • JPC776

    I can see a useful application for this, but I would rather charge mine for 6-8 hours at night and have it last 48-72 hours of moderate to heavy use.

    • Anonymous

      So there is no middle ground w/ you in the 12-20 hours huh. Straight for 2-3 days. LOL

      • JPC776

        I’m ok with the 12-20, but “I would rather charge mine for 6-8 hours at night and have it last 48-72 hours of moderate to heavy use.”

        • We’d all love this. I’d like to be able to pound on my phone for a solid 12 hours as only a 19 year old can do and still have some battery at night to call my boyfriend. I don’t need 72 hours, just a day!

          • Tony Allen

            I can easily get through a day on my Bionic with moderate use.. I would like to be able to forget about charging overnight, and it not be an issue the next day until it was time to come home from work.

          • JPC776

            I don’t need 72 hours either. All I’m saying is I would like it. I think with today’s technology it is possible. I get a solid days use out of my DX and I charge it every night, but if I forget one night or I am out of town for a day or two it would be nice to not have to worry about it.

            “I think with today’s technology it is possible.”

            Unfortunately, battery technology is not keeping up with the ever increasing demands mobile devices put on them. There are new technologies in the pipeline that will increase battery efficiency (nanotubes, ultra thin film) but none will be ready for years.

            The best we can do for now is maximize efficiency of the processors and software powering our devices. That and hope the manufacturers can figure out a way to cram a larger battery into a smaller device. 

  • ScottK

    My OG Droid charges up in a little over an hour, but unless I leave it charging for at least 4-6 hours , the battery dies twice as fast.  Sorry, but I’m not sold on the fast charge thing.

    • That’s because the battery on your Droid is so old — it is falsely registering as fully charged, it happens to all batteries as they age (or well, and lithium batteries anyway). This has nothing to do with the charging technology, but rather a battery limitation. Your Droid did not magically gain new charging technology because you have ad it for a while, and this Japanese company is not proposing that we start putting dead batteries in our phones so that we think they charge faster.

      • Tony Allen

        No, these new cells do not have a memory, that is old tech and no longer relevant. Batteries in our phones simply lose efficiency over time from being charged/discharged over and over again. Just how it is.

        • I never said that they do (that was another person). Batteries physically get damaged the more you use them (a.k.a the same thing you said). However, as they get damaged, the phone looses ability to accurately calculate the charge of the battery, since it doesn’t really know exactly how damaged the battery is. That is what I meant when I said it falsely registers as fully charged — since the notion of it being fully charged is a calculation of the phone (it still however, in reality, continue charging beyond that point if you leave it on the charger, although it does this much slower).

          However most lithium-ion batteries will continue to charge for a short time after reaching 100% (as reported by software).

    • Anonymous

      To add to what “Kiril” is saying: Your battery forms a memory over time that will continue to limit how much a full charge on the battery will be. So while your phone says that your battery is charged 100%. In reality it could have a 20% less charge capacity then at purchase after a few years or so.

    well, iphone has 8 hrs talk time now so no need for this…  must buy iphone must buy iphone….

    • TheAndroid1

      Do you really think that no android phone has 8 hours of talk time?

      • Eric V

        i think they do but i just dont see it so good bye thunderbolt Hello iPhone 4S

    • Billyrouth2000

      Why buy a child’s toy when you can have android?

  • Jarred Sutherland

    I really hope they can do it without causing overall life of the cells to die quickly. I don’t want to buy a new battery every few months.

      yeah over loading sounds bad.

      What does it matter if it charges in 10 minutes?

  • Mr.joe

    Mr. Tato!  I knew I could trust you!

  • Kierra

    Umm battery life would still be a problem. If it depletes as fast as it replenishes thts still not good.

    • The intake and output of a battery are different things. Input rates are usually based on the specifics of a battery, while output rates are based on demand (since demand is always lower than the battery’s transfer rate — otherwise, the battery would be useless). What this new technology is doing is boosting the intake rate (the transfer rate of the battery). Just think of it this way: we have been filling up our batteries with a garden hose, and this research is proposing that we fit a fire hose attachment to the batteries, so they let in a bigger stream — hopefully that’s not too abstract.

      • Kierra

        Huh? I’m glad that you know all this and I’m honestly not being snarky, but did this say anything about my battery not needing to be charged for at least 20 hours? If it then then 🙂

  • Anonymous

    That’d be crazy! Let’s hope they last longer than 10 minutes after a charge though too.

  • Viciousking1914

    Charge it for 10, use it for 45….Keep working on those long lasting battery technologies

  • Rob

    I know nothing of battery technology, but can a rapid recharge at that rate harm the battery?

  • If this came out in the near future I wouldn’t be as worried about battery life. Just stick it on a charger for 10 minutes and you’re good 🙂

  • Pon

    apple just insulted my bionic.. just called it a slow poke taking pictures.. says it can charge faster than it can take second shot.. =(

    • as a bionic owner too; they are pretty much right

  • Doug

    seems like that would kill the life of the battery in terms of how many times it can be recharged. if not, than yeah, that’d be the coolest.

    • I wouldn’t care. If I could charge in 10 minutes, I’d buy a new battery every 6 months. Worth it.

  • Tyk

    “Hell it’s about damn time”

  • This would be amazing!
