I have just charged using the 87W with apples usb C to lighting in an ip6s starting @ 14% to (50% at 30mins as mentioned in the forum) about 95% in 1hrs 45min without airplane mode with the latest iOS version. Stopped charging at 95% as I need to use the phone .

My tests iphone 8 (not plus)
1x Anker IQ 24w dual usb
1x Anker powerline 2 usb to lighting
30 mins - 9% to 59%
Second test
1x Anker powerport +5
1x Apple USBC to lighting 2m
30mins - 58% to 76%
In summary stick to Anker it’s cheaper and faster.

I don't understand your test. Neither of your Anker devices support USB power delivery. You need an Apple USB-C charger, or another charger that supports USB PD. You also need the official Apple USB-C to lightning cable for fast charging.
i don't know about 7 , but my 7+ draws around 8W using ipad 10w charger, so i don't think it can get faster than that.

most of usb-c chargers support PD, the fact is the i8 cannot draw more than 11-12W, so it's not needed powerfull usb-pd charger, can work with ipad 12w charger.
Great article that summarizes the so-called “fast charging”: https://www.cultofmac.com/508351/apples-fast-iphone-8-charger-isnt-as-quick-as-you-think/
Conclusion - save your money and get a 12W charger and a MFi USB-A to lightning cable

Wireless charger from samsung fast charge is not slow at all? Who told you it’s slow. I am not even using fast charger which apple is selling. I have charged 8 on it and it really fast. I don’t even have need for apple’s fast charger now.
Nice graph to show there differences in the fast charging bricks everyone was saying that there’s no difference between the 29 and 87 watt adapter
I’ll gladly take those 4-5 extra minutes with my 87watt adapter

Well, you are actually missing the point of the article. Although the 8+ charges at 18W, the real world speed is almost the same as 12W charging. This makes it pointless to get it because you have to pay a lot more to get only slightly faster charging.
18w input does not mean 18w charging, because the running phone also uses power, so for example it can use 12w for charging and the remaing 6w for running , which is great for me because i mostly use it on Waze with screen brightness max on hot days.
Hmmm... this could be a fair use case, although someone will need to run additional tests that show that the 18W charging actually allows for (significantly) faster charging under heavy load versus the 12W charger.
Phones I've used in the past would reduce charge to 1A when the screen was on - not charging past 1A. I thought iPhone did this too but I don't have access to a USB voltmeter anymore. But I know several of my past phones did this (can't remember if Android or iPhone).
I have the X and the 29W and the 87W USB-C macbook charger with the USB-C to Lightning cable. When I had my 6S jailbroken I could get real battery/charging info.
Not sure how I can test it. I have a voltmeter, but a dedicated "USB-C voltmeter" would probably be more accurate.

yes, in the meantime, i have ordered USECORE USB-C Power Meter 17$ from china a few weeks ago , it should arrive soon.
Hooked up my iPhone X to a Trianium PD Car Charger and it negotiated 9.13v/1.8a so just about 18w. As expected it dropped off to about 5 watts in the higher battery percentages.
Quick test with my iPhone X at around 45% charge.
USB-C PD:
29W Apple charger: 14.5V/1.1A (16W)
Anker PowerPort+5: 9.2V/1.9A (18W)
USB-A:
12W Apple iPad charger: 5.1V/1.6-1.7A (8W)
So PD is supplying quite a bit more power than the 12W charger and seems to prefer the 9V/2A profile when given the choice - the Anker supports 9V or 15V.
I haven’t timed the total charging duration but looks like others have above. Not sure why the Apple 12W only outputs 8W but perhaps my battery level was too high when tested (45% as mentioned above).

The image you posted with faster 61/87W charger results is consistent with my tests where the iPhones prefer 9V/2A (18W) over 14.5V/1.1A (16W). The 61/87W chargers support 9V PD, while the 29W only does 14.5V.

18w it's faster than samsung/qualcomm quickcharge 2.0 15w, so it's a real quick charge, it doesn't need any improvement !

@y0zza , seems like 8 plus prefers 15V for 18W output and the X 9V
[doublepost=1510832240][/doublepost]weird that it prefer 9V , since 15V is better (lower current) for the transfer, not requiring higher quality cable/connections (lower resistance).
also, keep in mind that the usb power meter has it's influence in the circuit , a little voltage drop , and introduces some resistance on the pins since there are more connections, that could influence in selecting the proper PD voltage.

Interesting - but I’m not sure the 61W actually outputs 15V.
According to Apple’s specs:
Input: 100-200V ~ 1.5A(1,50A) 50-60Hz
Output: 20.3V - 3A (USB PD) or 9V - 3A (USP PD) or 5.2V - 2.4A
Using the same cable and Anker charger my iPad Pros do pull 15V/1.9A, so it seems specifically my iPhone that prefers 9V where available.
