This killer trick will charge your iPhone 6 in half the time

The iPhone 6 and iPhone 6 Plus are the biggest iPhones yet. But that comes with a drawback: Since they have bigger batteries than any iPhone ever, they also take longer to charge.

But here’s a killer trick. You can use a 12-watt iPad charger to juice up the iPhone 6 and iPhone 6 Plus in half the time when compared to the 5-watt iPhone charger your device ships with by default.

That might seem like a no-brainer, but believe it or not, this didn’t work with previous iPhones. If you plugged an iPhone into a 12-watt charger, it would charge at only 5 watts, leading to much slower charge times.

Batteries are complicated, but think of charging a battery like filling up a water balloon. When you’re trying to fill a balloon as fast as possible, it doesn’t matter how fast your hose can spray water if the mouth of the balloon is too small to let it all through.

That’s, in essence, what was happening with old iPhones. The battery just couldn’t suck up electricity as fast as a 12-watt charger was squirting it in. But with the iPhone 6 and iPhone 6 Plus, that’s no longer a problem: They’ll suck up electricity as fast as your charger can squirt it.

So if you’re frustrated by how long it takes your iPhone 6 to charge to 100 percent, try plugging it into your iPad charger.

    That’s a killer, alright. Cause eventually it will kill your battery life.

    • jrb

      ….it doesn’t on all other devices.

      • NicWol

        Like, an iPad Air? No, because that is the supposed charger for the unit.

    • DigitalBeach

      Is that a fact or theoretical assumption?

      I would love to see the data supporting this claim.

      • NicWol

        Mostly empirical. I’ve experienced it myself, and I worked at an Apple Store where a good amount of customers with battery issues told me they were using their 12W-chargers to charge faster.

      • RyanTV

        That’s crap. I only use the 12w on all of my devices and I’ve never had any battery issues. None. Zip.

        Just because you “used to work at an apple store” doesn’t mean you have any answers. The fact of the matter is the circuitry within regulates how much juice goes into the battery and trickle charges it at the end avoiding overcharging the unit. Overcharging is what really screws a battery and why using a non-apple charger can be risky.

      • NicWol

        Did you catch the word ’empirical’? I didn’t state this as facts, but purely on what i have experienced. So EXCUSE me, cocksucker.

      • groberts1980

        Sorry if I decide to believe someone who worked at an Apple store over your singular anecdotal evidence. So because you claim to have had no issues, that means nobody will have issues, ever? I hate when people use their own anecdotal evidence as proof of anything. It just shows how clueless they are.

    • sam graves

      This comment is just blatantly false. Apple has enabled much faster battery charging in the newest iPhone models. According to specs, both of the new iPhones are equipped with the hardware to support 2.1A charging (same as iPad), even tho they still come with a 1A charger pack in the box. None of the previous iPhones had this ability.

      • Spee

        Agreed! Here’s proof as well, straight from Apple’s site. If it was going to damage your phone they wouldn’t include on the compatibility chart…
        PLUS, even if your claim was remotely true regarding damaged battery life, it would take a long time for that to happen and there will likely be 3 or 4 new iPhones made in that time. People also need to consider how much they use their phones throughout the day and what they’re using it for when discussing battery life…lots of factors

  • Doc_Sportello

    I’ve been using a 12W charger with my iPhone 5 for a while, and it definitely charges more quickly than with the 5W charger I’ve kept as a back-up. I don’t know if I’m getting the full 12W, but I’d guess charging times have been reduced by about 50%.

    • http://upthetree.com/ FuntimeBen

      Same here with a 4S and it hasn’t effected the battery life at all.

  • alunaaxxx

    Will it damage the battery?

    • Jon Nguy

      No

    • NicWol

      It might.

    • R3sp3ctfu1Gam3r

      I’ve seen batteries explode under the right conditions during rapid charging. I wouldn’t imagine that ever happening in this scenario but I plan to play it safe.

  • Bash Maxwell

    The title smacks as one of those fake internet articles… “One weird trick…” please don’t.

    • Nick

      You won’t believe how he managed to charge his iPhone in half the time!

    • Spikelives

      I never believed those stories I read in magazines and websites until I had an experience that changed, my life. My roommate was out for the night when I heard a knock on my door and this 12W charger was there wearing nothing but a smile…

  • Steve R

    So why don’t Apple include a 12W charger with the new phones instead of a 5W ?
    Probably because the batteries will suffer long term as a result.

    • ButchM

      Or … maybe the 12W charger would further raise the cost thus reducing profit margin. Plus Apple would need to add additional cost for the increased size in packaging to allow for the additional bulk of a 12W charger.

    • RyanTV

      Cost and size I’d imagine. The box for the iPhone would have to be considerably bigger if it had a 12w adapter meaning that less units per pallet would be able to be shipped which would exponentially increase costs.

    “They’ll suck up electricity as fast as your charger can squirt it.” *giggle*

  • Jack Holland

    ‘believe it or not, this didn’t work with previous iPhones’

    No I don’t believe it because it’s not true. I’ve been using an iPad (3rd generation) charger to speed up my iPhone 4S & 5 charging since it was released in 2012. Battery life is fine.

    • justme

      I agree with you, my battery is fine too 1 year with my iPhone 5 charging with iPad battery.

  • your mom

    wait, you mean some people DON’T use iPad chargers for everything? Mind blown!

  • justme

    I knew it!
    actually I use the iPad charguer on my iPhone 5 because I lost mi little square.
    so, I notice that the charging time is more fast than before.

  • Dude321

    FYI, iPad charger is compatible with your iPhone. Check compatibility http://store.apple.com/us/product/MD836LL/A/apple-12w-usb-power-adapter?fnode=3c

  • kopaka7

    Rapid-charging isn’t safe for device batteries. That’s why smartphones trickle charge after 80%.

  • SpaceMonkey

    I’ve been using my iPad charger with my iPhone 5 exclusively for two years, and see not noticeable issue. It charges zero to full in a couple of hours and lasts most of the day. I have no concerns about this!

  • http://www.feastofbeast.com DJBabyBuster

    Yep was charing my 5 (and now my 6Plus) with my iPad charger for the past two years. Definitely noticed an improvement in charging times even on the 5, and no issues ever with killing the battery.

  • Gary LE

    Just use the charger that came with your device to be safe people!
