Semi-ad but does have some good information about the standard Apple chargers and how they differ with fast charging capabilities. All tests done with standard Apple usb-c to lighting cable (because that's what Apple advices when using high W chargers).

Definitely not much better than 12W charging. It’s a very meh situation.
Here is the best i could do with the 10W charger on Iphone 8+, ios 11.01, wifi, bluetooth on
YES this is the old 10W unit, NOT the 12W

it took so long i quit. I will be only using my 29w charger!

Whenever they retrofit the 7/7 Plus with a USB-C Power Delivery chip found in the 8/8 Plus.
My 7 charges 47% in 30 minutes with the 29W charger. I think that is rather decent.
No doubt. But you'd get that same speed/charging time with the (iPad) 10/12w chargers.
Hmmmm.... it only confirms the observations so far though. It seems like the last charger was probably charging at 12W.... ie the 12W charger charges almost as fast as 29W. Again, not particularly impressive.
It makes more economical sense to stick with 12W charging unless you happen to have a 29W or more powerful charger handy if you also own an iPad Pro or USB-C MacBook.
you mean where it was at 46% in 30 mins? the brick there was a 21w charging brickHmmmm.... it only confirms the observations so far though. It seems like the last charger was probably charging at 12W.... ie the 12W charger charges almost as fast as 29W. Again, not particularly impressive.
Yes, I know. I just doesn’t accept the fuzz about fast charging iPhone 8. I’ve seen several reports about ppl getting 46-50% in 30 mins. If getting a 29 W saves you 2 minutes compared to the 12 W charger I think people are entitled to know it before blasting 60-70 or upwards of $100 in some countries on it.
That is why I think a few guys would learn something new if some of the ones that did reviews of the fast charging option compared it to an iPhone 6s/7.
Unfortunately that means very little. It was most likely negotiating 5V/2.4A. 21W does not match any known V/A charging speed I’ve known, possibly some fancy Qualcomm Quickcharge tech? Regardless, that isn’t a protocol recognized by iOS devices. Only USB-C Power Delivery has been known to work so far.
Good vid, but still missing some info.
OK, so I think (?) I'm the first person to confirm/test this, but it actually aligns with the video above.
First, some of my assumptions about the iPhone 8 Fast charge capability were wrong, because the 8 doesn't behave the same as the iPad Pro 10.5 and both 12.9 models. We know the iPads (using USB-C) can charge at either 29W (2A @ 14.5V with the Apple 29W charger) or 18W (2A @ 9V with the Apple 61W or 81W chargers).
^^^This is not what happens with the iPhone 8!
Based on my testing with a P3 Kill-A-Watt meter, along with an Apple 1m USB-C to Lightning cable, and both the Apple 29W and 61W bricks, my conclusion is that the iPhone 8 can only maximum charge at 2.4A @ 5V! This is equivalent to about 12 watts, only slightly more amperage than you'd get/expect form a 10W/12W "iPad" charger, which outputs 2.0A @ 5V (i.e. 10W) to any recent iPhone.
In summary, don't go and buy the 29/61/87W Apple chargers, expecting more/faster charger, vs. what you'd get with Apple's 10/12W iPad chargers.
Thanks for the info! It provides a good data point. I assume you don't have / didn't test against the iPhone 8+ then - I am now wondering if the 15V charging is only enabled on the 8+.
Actually, I do have an 8 Plus (my wife’s), but it is currently at 100%. I will see if we can get that battery drained a bit in the next few days, then give it the same test as above.
This is wrong. Theres a video on Youtube which shows a 29 W charger peak at 23 W.
OK, good news. I was able to test our iPhone 8 Plus tonight, which reported 32% battery when I began.
Using both the Apple 29W and 61W charger, the 8 Plus was successfully able to negotiate 1.2A @ 15V for an ~18W power delivery. This is in contrast to my standard iPhone 8, which can do 2.4A @ 5V for 12W power delivery.
TL;DR - iPhone 8 Plus can charge incredibly fast using the Apple USB-C to Lightning cable and Apple 29W/61W/87W chargers. Using the same cord/brick(s), the regular 8 can only charge at 12W, just marginally faster than an iPad charger + standard Lightning cable.
NOTE: these “Fast charge” rates are only obtainable when the battery is <50%. Above that rate, the draw will slow down significantly, reduced to 5-6W when passing 80%.
Yeah just wow. Most of my Anker chargers are comparable to the green 12W charging bar... No way in heck I'm going to pay $70 for a 10% charging difference. that and the fact that my phone spends MOST of its life 80-100%.... lol.
@ above post - how interesting 8+ charging differently than the 8.
My testing in half an hour with the 29w charger
It charged 34% in 30 mins on my 7 plus
Going to test the same on my iPad Pro 12.9

Well...so far as fast charging is concerned using the 29W charger. No real discernable difference compared to the 12W ipad charger.
Tested on my iPhone 8 Plus with wifi on and screen off. Starting point : 5%
