Are there faster iphone chargers

Fast charge your iPhone

Use fast charge with certain iPhone models. You can recharge your iPhone up to 50 percent battery in around 30 minutes.

You can fast charge your iPhone 8 and later up to 50 percent battery in around 30 minutes. 1

Fast charging works when you use an Apple USB-C to Lightning cable and one of these adapters:

• Apple 18W, 20W, 2 29W, 30W, 61W, 87W, or 96W USB-C Power Adapter
• A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)

If you’re not sure which Apple Power Adapter you have, check the wattage on the top or bottom of the adapter:

iPhone X Charging Speeds Compared: The Fastest and Easiest Ways to Charge Your iPhone

With the addition of both fast charging and wireless charging to Apple’s 2017 iPhone lineup, there are more ways than ever to charge your iPhone. Every method is different — some are faster and more expensive, while others are slower but more convenient.

We tested several charging accessories from both Apple and third-party manufacturers with the iPhone X to see how charging speeds compare across different charging methods. These tests also apply to the iPhone 8 and 8 Plus, which share many of the same features available in the iPhone X.

Accessories Tested

The 5W and 12W chargers from Apple were paired with a standard Lightning cable from Apple, priced starting at $19. All USB-C charging accessories were paired with a USB-C to Lightning cable from Apple, priced starting at $25.

Methodology

We used the same iPhone X for all tests, plugged into the same outlet. Between tests, the battery was drained to one percent, and then battery percent was checked at 15 minutes, 30 minutes, 45 minutes, and 60 minutes while charging.

For all tests, the iPhone X was placed into Airplane mode with no apps running. The display was deactivated except for the four time checks. Tests were conducted without a case on the iPhone X.

Results

The absolute fastest way to charge an iPhone 8, iPhone X, or iPhone 8 Plus is with a USB-C power adapter and an accompanying USB-C to Lightning cable. Charging with USB-C activates a «fast-charge» feature that’s designed to charge the iPhone to around 50% in 30 minutes, and I saw about that level of charge in all of my USB-C tests.

5W wireless charging and 5W wired charging with the standard iPhone adapter were the slowest methods that I tested. 7.5W wireless testing was faster than 5W wireless charging, but not by much.

I tested both Apple’s 29W and 87W USB-C chargers that come with the 12-inch MacBook and the 15-inch MacBook Pro, respectively, along with much cheaper 18W and 30W chargers from Choetech and Anker. I saw little difference in charging speeds between 18W and 87W.

Apple’s 29W MacBook charger costs $49 and the USB-C to Lightning cable costs $25, so you’re looking at about $75 for this charging method, but luckily, third party USB-C power adapters work the same way and are more affordable. That 18W Choetech charger I tested, for example, is just $18, while the one from Anker is $30.

Standard iPad and iPhone Chargers

All of Apple’s iPhones ship with a standard 5W power adapter and USB-A to Lightning cable, and charging with the standard setup is excruciatingly slow comparative to other charging methods. It’s not faster than 7.5W wireless charging and it can’t compare to charging with power adapters that put out more juice. At 30 minutes, for example, it had only charged my iPhone to 21 percent, and I only made it to 39 percent after 60 minutes.

That’s not too bad for a setup that’s one of the most affordable I found, and there are a lot of 12W equivalent third-party charging options on the market, including several with multiple ports and other conveniences.

Wireless Chargers

In general, wireless charging is slower than wired charging, but it’s undeniably convenient, and if you’re charging for a lengthy period of time, say at your desk at work or overnight on the night stand, the slower charging doesn’t matter.

That said, 7.5W wireless charging, which was activated in iOS 11.2, was faster than the standard 5W wired charging method in my testing. There’s also a noticeable but slight speed difference between 5W wireless charging and 7.5W wireless charging.

I also tested a Choetech 5W charger that was much slower than the Belkin at 5W, so much so that I wasn’t sure it was an accurate representation of 5W charging. From 1%:

— 15 minutes: 9%
— 30 minutes: 19%
— 45 minutes: 27%
— 60 minutes: 35%

There wasn’t a huge difference between 5W and 7.5W charging in my experience, but 7.5W is faster. If you’re buying a wireless charger, it’s worthwhile to get a 7.5W+ charger that offers faster charging for the iPhone, but which chargers are compatible with 7.5W wireless charging remains something of a mystery.

For a separate post on wireless charging options, we’ve been investigating third-party wireless chargers, and it’s looking like there may be a restriction put in place by Apple to limit 7.5W charging to approved manufacturers. As an example, on the Amazon page for this charger from Choetech, which says it is 7.5W, there is this message:

We get notice from Apple engineer that current IOS only support 5w qi wireless charging currently, 7.5w wireless charging is encrypted and never released to 3rd party manufacturer.

We’ve heard similar information from other manufacturers, but it’s all very nebulous and not something Apple has clearly outlined at this point. For that reason, if you want confirmed 7.5W wireless charging, go with the Belkin, the Mophie, or another charger that specifically states that it’s compatible with Apple’s 7.5W charging.

On the subject of wireless charging, I also tested to see if case thickness impacts charging speed. I tested with a naked iPhone X, an iPhone X in Apple’s Silicone case, and an iPhone X with one of the thickest backs I could find, the glitter-filled iPhone X case from Casetify. Charging speeds were almost identical in all three tests, and while the Casetify case was maybe about 2 percent slower, that can perhaps be chalked up to margin of error. There was zero difference with the thinner Apple case.

If your case works with wireless charging at all (and most do, with the exception of those that have rear magnets or are made from aluminum), it’s going to charge at the same speed or nearly the same speed as a naked iPhone.

Conclusion

To get fast charging on iPhone X, iPhone 8, and iPhone 8 Plus, you don’t need anything over 18W, and you don’t need a USB-C power adapter that’s from Apple. The third-party options work just as well, but you will probably want to pick up Apple’s USB-C to Lightning cable over the alternatives.

Fast charging is going to get you the best charging times, but for less money, you can get the 12W iPad charger and use it with a standard Lightning cable to charge your iPhone almost as fast as you can charge it with fast charging. There’s only about a 10 percent difference between the 12W iPad charger and USB-C charging.

It’s not really worth it using the 5W charger that the iPhone ships with if you can help it, because it’s incredibly slow.

Wireless charging is also a comparatively slow charging method, but it’s convenient to be able to set your iPhone right next to you on a wireless charger and pick it up when necessary without the need to hassle with a cord.

8 ways to charge your iPhone faster, including using the right charger and taking it out of direct sunlight

Charging up your iPhone sounds like it should be a straight forward task. But there are a lot of ways to speed up (or unintentionally slow down) the charging process.

If you’re in a hurry and need more battery life as quickly as possible, here’s how to make your iPhone charge faster.

Check out the products mentioned in this article:

iPhone Xs (From $999 at Apple)

iPhone 8 (From $399 at Apple)

30W USB-C Power Adapter (From $49 at Apple)

USB-C to Lightning Cable (1 m) (From $19 at Apple)

30 Watt USB-C Wall Charger (From $25.99 at Apple)

30 Watt USB-C Charger (From $13.99 at Apple)

Use a wall charger

First thing’s first: Using a wall charger — any wall charger — is going to be faster than plugging your phone into a computer’s USB port. Use a wall charger if you have one.

But not all wall chargers are equal. In general, the higher the device’s wattage, the faster it can deliver a charge to your iPhone. The wall charger that comes with your iPhone is relatively anemic, rated at 5 watts.

If you have an iPad, use the wall charger that came with it instead, since it delivers 12 watts and charges about 33 percent faster.

If you have a new iPhone, use a fast charger

The newest crop of iPhones (which include the iPhone 8, iPhone 8 Plus, and the iPhone X family) include fast charging. Paired with the right wall charger, these phones can go from empty to 50 percent charge in half an hour.

Apple doesn’t include a fast charger in the box, though. You need to purchase a fast charger and a USB-C to Lightning cable. Apple offers its own 30 Watt USB-C Power Adapter and USB-C to Lightning adapter cable .

There are other fast charging options as well. Anker offers a 30 Watt USB-C Wall Charger , for example, and iClever has its own 30 Watt USB-C Charger . There are a lot of affordable choices.

Don’t charge wirelessly

Wireless charging (if you have a newer iPhone, or you’ve put an old iPhone in a wireless charging case ) is admittedly a convenience. But like most conveniences, this one has an unintended cost: slow charging.

Wireless chargers work much more slowly than plugging the phone into a Lightning cable, which is why you should skip wireless if you’re in a hurry.

Turn the phone off

Your iPhone will charge more slowly if it’s powered on and performing tasks while it’s also trying to send current to the battery. The best solution is to simply power it down.

Start the Settings app, tap «General,» and then tap «Shut Down.»

Put it in Airplane Mode

Sometimes it isn’t practical to turn your phone off completely, but the next best thing is to put it in Airplane Mode. In Airplane Mode, your phone disables Wi-Fi and cellular service, which can save a significant amount of power, letting the phone charge faster.

To do that, pull down the Control Panel from the top right of the screen and tap the airplane icon at the top left. Or, if you’re using an iPhone older than the iPhone X, swipe up from the bottom of the screen and tap the airplane icon at the top left.

Avoid using it

You can probably guess where this is going: Just avoid doing anything with the phone while it charges. Don’t stream music, browse the web, or check email. Put the phone down and leave it alone to charge in peace.

Keep it cool

Batteries are little chemical factories, and when you charge a phone, the electric current causes chemical reactions to happen deep inside your phone.

These chemical reactions tend to heat up the battery, but they work most efficiently when the phone is cool. You can help the phone to charge faster by keeping it out of direct sunlight and in a cool location if possible. If you keep the phone in a case, consider taking it out of the case while it charges — many cases trap heat, which is bad.

In fact, if the phone gets too hot (about 95 degrees), it may stop charging completely until it has an opportunity to cool down.

Cycle the battery occasionally

This isn’t something you can do in the moment, but put this on your to do list.

Your iPhone’s battery will charge more efficiently if it has a chance to cycle — to go from 100 percent to completely dead about once a month or so. Every once in a while, let your phone run down all the way until it shuts down.

Question: Q: Will fast charging the iPhone 6s shorten battery life?

Has anyone been charging their iPhone 6 or 6s with the 12W iPad USB power adaptor? How badly does this affect the battery’s longevity in the long run?

iPhone 6s, iOS 9

Posted on Oct 17, 2015 11:13 AM

Helpful answers

Yes I’m sure it’s perfectly safe since Apple endorses it; however I wanted to know how it’ll affect the battery’s longevity in the long run. The faster a battery is charged the quicker it’ll degrade and thus have a shorter life.

Not necessarily true. SMART Lithium batteries have a range of charging amperage they will allow without any measurable difference in battery life. Apple enabled the 2.1amp charging on the new iPhone 6s but iPads have used that setting for years without any eccessive degradation in doing so. Note that the device actually controls and regulates the charging process and current, not the power supply (that is true for any and all SMART Lithium cells as it is part of the international SMART technology standards).

As it is a charger that Apple specifically sell for use with both iPads and iPhones, it’s perfectly safe. I don’t think I’ve used anything but the chargers that came with my iPad for my phones since I first got an iPad.

The electronics may have become smarter over time, but Li-Ion technology is decades old. It’s still a chemical pile. All chemicals degrade quicker when more heat is applied.

If you aren’t going to believe the answer, why did you ask the question?

Oct 18, 2015 8:22 AM

The electronics may have become smarter over time, but Li-Ion technology is decades old. It’s still a chemical pile. All chemicals degrade quicker when more heat is applied.

Get your facts straight. Practical Li-Ion technology is NOT decades old, it is far less than a decade old. While there were a number of attempts to produce practical Lithium chemistry batteries, it has been less than 10 years since safe, successful Lithium ion cells have been on the market.

Charging a Lithium-ion battery within its design envelope has no effect on the battery life. Consider that the Tesla model S uses Lithium ion technology, and a depleted pack can be fast charged in 2 hours, then provide 250 mile range.

ADDENDUM: To come back to the original question, you cannot «fast charge» an iPhone 6 or 6S (or any other iPhone). You can use a USB power adapter that can supply 2.2 amps (like the iPad adapter), but the phone will only use 1.6 amps, and that only for the first hour of charge before it reduces the charge rate. iPhone 5 and earlier will only use 1 amp, so there is zero benefit (but no harm) in using an iPad adapter. And the charging circuit in the phone monitors temperature and state of charge to assure that it will not overcharge. For that matter, you could use a USB power source that could supply 1,000 amps, and the phone would still only draw 1.6 amps.

«Not necessarily true»

You are correct in that the iphone is capable of slowing it’s charging rate to one that optimizes battery longevity. In the same way ip6 can shorten charging time for user convenience to an extent that shortens battery longevity, because li-ion batteries heat up when charged, and faster charging rates create more heat. Too much heat begins degrade battery longevity. My Makita cordless tools charge in a charger with an internal fan to cool the batteries and the battery cases have holes to permit air flow over the individual cells.

You express a hopeful opinion but cite no support for your opinion. My experience with my ip6 is that a full charge seems to last shorter and shorter. I’ve been using a charger that can supply two amps and have noticed my phone gets hot. Shorter charge time makes ip6 users happier with the phone. It also rings of planned obsolescense since ip6 users will more likely replace their phone when the next version is released if battery life has fallen through the floor. On the flip side of my personal sitch I’ve got about 36GB of apps and data in my phone and stream audio a lot

That is perfectly normal for rechargeable batteries as they age, regardless of how you charge them.

And you present a pesimistic (with a hint of industrial planned obsolescence conspiracy theory) with no supporting evidence. I base my comments on information readily found in numerous technical documents available with a simple web search. And, my use of Apple Lithium Ion and Lithium Polymer devices over many years (iBooks, Powerbooks, MacBook Pro’s, iPhones, iPods and iPads) also supports my contention that charged simply as Apple designs their products, there will be no user noticeable excessive degradation of battery life. If Apple enables 2.2 amp charging on a device, they did so after testing and without altering their own officially stated assurance of minimal battery life of up to 80% capacity at 500 full charge/discharge cycles. That claim makes no mention of which Apple power brick one uses to charge the iphone.

My opinion is not merely a hopeful one, it is based on extensive reading and research of SMART lithium standards and technology (information readily available to anyone online), and use of many devices over many years in my own hands.

Every single battery technology ever created shows a decline in battery capacity with use and time. That is perfectly normal. But Apple’s charging systems built into their devices do not inherently increase that steady decline beyond what would normally happen with accumulated battery discharge/charge cycles and simple passage of time.

Like most of you, I’ve owned many electronic devices that use Li-ion batteries. Though I don’t work with batteries professionally, I’m an avid follower of battery technology, a gadget freak, tinkerer (including soldering up circuit boards). I have had my phone only for a matter of months. The batteries in my phone *seem to me* to be declining too quickly, based on solely subjective personal criteria without comparison to any objective data regarding ip6 battery performance. This is the sole reason for my arrival here today. This is actually the first place I landed, but I intend to look to further sources as well. Hopefully I’ll avoid entanglements there more successfully than here.

Regarding planned obsolescence, I am not a consiracy theorist nut job. It’s worth noting that planned obsolescence is not illegal and is a business decision chosen by many producers of many goods. It is possible to plan obsolescence in an illegal way, but it is not illegal for Apple to sacrifice battery longevity for quick charging, unless they make claims to the contrary. There actually are major corporations that make products in an illegally deceptive way. Take VW’s diesel emission scandal, for example. I used tentative language and did not accuse Apple of illegal planned obsolescence. What I said about the trade off between fast and slow Li-ion batteries is true. What you said in your last post seems true to me as well and I see no reason to disagree with that.

Your response to me seems a little defensive, so I feel the need to apologize. I did not mean to offend you nor impune you in any way and I’m sorry if I came across wrong. However, my response to you had the desired effect: while your initial post was written as an expression of opinion, your response to me cited factual information very germane to this thread and I thank you for that.

So I’m discussing my personal experience with my ip6 as well as general factors such as standards for charging Li-ion batteries. You all may very well speak to the generalities but I’ve not given you enough information to make a decision about my specific phone, just to keep things in perspective.

If my apology somehow wasn’t acceptible, I will not carry on further in that vein. Rather, in any further posts I may write I’ll try to keep more carefully to the OP’s question.

Thank you all for your participation in this mutual help forum.
