I seem to have lots of chargers from all of my past iOS devices some 5, 10 and 12 w chargers. Does the 6S+ support faster charging with the 10 and 12w chargers?

I keep reading about how it charges faster with the 12w charger. So I picked one up and did a 0-100% charge test.

0-25% 23 minutes
0-50% 47 minutes
0-75% 80 minutes
0-100% 162 minutes

So I would say that up to around 70% it's probably pretty close to 1% per minute. This isn't fast charging to me. Some Android phones can get to 50% in 15-20 minutes.

I'm not sure what charging times would be on the included 5w charger as I've only used the 12w on my iPhone 6S plus.

50% in 15-20 minutes? I think you may be over-exaggerating there. The only device that I know that can charge extremely quickly is the Droid Turbo/Turbo 2 and thats because it has a 15W charger. But once the device reaches 78% it charges at normal speed again. So only 0-78% take advantage of the 'TurboCharger'.

The S7 with the quick charger takes 86 minutes to go from 0-100%. 0-41% in 30 minutes and 0-88% in 60 minutes. Still takes another 26 minutes to go the last 12%.

Faster the charge means the battery is getting hot, and heat degrades battery. So I would gladly take a slowly charge time for a healthy battery in the long run.

It's not about fast/quick charging, it's about faster charging compared to the typical included 5w iPhone charger.

Good amount of this type of discussion has just happened at https://forums.macrumors.com/threads/using-29-watt-charger-on-iphone-6s-plus.1975894/

Thanks for posting this. After seeing the charge times for the S7, I'm not annoyed by the 6S plus charge times any more. And the 15-20 minutes may have been an over-exaggeration but I thought at one point I had read that other phones were capable of that.

It's not about fast/quick charging, it's about faster charging compared to the typical included 5w iPhone charger.
Gotcha, I misunderstood then. Thanks for the clarification.
 
The 12w charger is all I use. I've purchased additional ones for my office and home, plus one that travels in my bag. Charging with the 5w charger is painfully slow. I hope we'll see some sort of more advanced charging capabilities or faster default chargers bundled with iPhone 7.
 
I use a 10w iPad 2 charger with my iPhone 6s, and then my 12w iPad Air 2 charger with my Air 2. I figure that being a 6s and not 6s+ I don't need a 12w charger, and the 10w charges faster than the 5w already.

It does, indeed. However, my iPhone 6S Plus easily lasts me all day, so I only use the stock 5W charger overnight.

Remember that Android phones have larger batteries, so the fact that they can charge in half the time as the iPhone says a lot. The great thing about fast charging is that you use it when you need it, if you are only at home or in the car for say 30 minutes, you can regain easily 50% charge on an Android phone that supports QuickCharge. Qualcomm has said themselves that the heat generated doesn't cause much of a hit on battery life. If you think about it, your phone can get extremely hot just being outdoors on a hot sunny day, used in the car for navigation, stuffed in an Otterbox case, etc.

First off, the power adapters, are not chargers. The charger circuit is built into the iPhone. The power adapters are transformers taking 110vac 60Hz or 220vac 50Hz to 5vdc.

The built in charger will draw only what it needs from the power adapter to run and charge the phone. With a 12 watt power adapter you can achieve a 1% increase per minute to the battery level from 0-70% or so. After that the charging circuit will reduce the draw until at 99-100% charge level only an intermittent trickle charge is provided to the battery. This prevents overcharging and damaging the battery.

So using the iPad power adapter will provide a faster charge than using the cube power adapter supplied with the phone. Apple has made charging simple and bullet proof for even the dumbest user. Plug it in using Apple power adapter, any one, use Apple cable and forget it. Leave it plugged in and phone will not overcharge or damage battery.

It can't be any simpler, even if people want to over complicate and see issues that are not really there.
 
I actually thought I heard somewhere that it's not recommended to use the 10w or 12w chargers with an iPhone, as it can damage the battery. I can't remember where though.

This is absolutely NOT true. No harm done using the 5W, 10W or 12W charger with the iPhone or the iPad (though the 5W charger will take a very long time to charge an iPad).

Seems like the information in this thread have shown that not to be the case.
 
So I would say that up to around 70% it's probably pretty close to 1% per minute. This isn't fast charging to me. Some Android phones can get to 50% in 15-20 minutes.

Quicker, my moto x pure gets around 70% in about 20 minutes and a full charge in a little over an hour.

That being said I have a 6s plus that should be here next week.

Actually no, my moto x pure gets better than that with the 15w charger. I get 70% in about 20 minutes and then it slows down to get a full charge a little over an hour.

Maybe you have a bad s7, my battery is not warm at all (moto x pure) when charging. It's cooler than when in use. If it's designed to charge at that speed then it should not be getting too hot, phones are set up to accept up as high as they can accept so they won't let it get fast enough to mess up the battery.

As far as using higher rated chargers, mentioned in the thread, I don't know of any phones or tablets that will have problems with higher rated chargers. They all, not just apple, are designed to take only what they can handle. Welcome to 2016.

Maybe I was thinking of older phones, but you guys are probably right.

I do have an ingress/cheero power cube that has separate USB charging ports, one is 1.0 and the other is 2.1, and it does feel like the 2.1 charges my phone faster than the 1.0, but that might be the same charge rate of the 5w adapter. I'm not sure quite how it works though.

But from what I've read here and what I've read on Apple's site and other googling, there's no real reason to get an overpowered adaptor for an iPhone as it will make little to no difference because the phone will limit itself on how much power it draws at once. Sorry if my semantics there are all wacky.

You read, but you do not understand. It's been mentioned several times in this thread already that the iPhone does charge faster using the large iPad charger. I use one daily.

I was combining the information from different sources. Even if it's faster, is it twice as fast? I'm legitimately asking. In your opinion, if you don't already have one, is it worth purchasing it if you already have the 5w?

I already had one here, from my iPad. No, I would not go buy one just for my 6s+.

I think I'm rushing my responses a bit. Here's what I really think I understand, feel free to correct me if I'm wrong. And if I'm wrong, please don't take it offensively. I swear I mean no harm:

1. Yes you do get a faster charge, but just because 10 = 2x5 doesn't necessarily mean half the charging time. The phone will get as much power as it's allowed to handle without damaging the battery.

2. I'm asking if it's worth getting the 10/12w if you don't have it already, to replace the 5w, based on the increased charge speed. I understand that wasn't really part of the OP.

3. Based on my power cube experience, USB output plays a part in charge. I would like to understand this more--I'm inclined to think that the 5w charger outputs at USB 1.0 and the 10/12 outputs at USB 2.1.

Thanks for your responses so far.

It primarily applies to iPhone 6 and later phones, not before. It won't really be twice as fast, but it can be faster, especially comparatively speaking in circumstances when the phone is being used in some way while it is being charged.
 
It charges wicked fast with the 29w charger and the apple USB-c to lightning cable
