well duh, that was pretty stupid of me.. once again fingers moving faster than neurons.
updated above iphone 8+ is where I am having this issue. My ipad 9.7 pro doesn't do it, goes to 100% quickly and stays there.
Got a tip for us?

Hmmm.... I haven’t really done extensive testing of fast charging on my iPhone X, but third party chargers may be unable to deal with how iPhones throttle their charging speed when almost full. I recall seeing this before if I charge something beginning above 90%, so I would drain it below 90% and charge again, and it would correctly reach 100% after.
You can try that “tactic” to see if it works, but I suspect the Apple official chargers may be better able to handle this.
The answer to the last bit is "Yes". Unfortunately, this sort of thing is where you start having to troubleshoot. For me, it usually involves swapping out parts to see which one makes the issue go away.
But I will say I've been using the Anker 60W charger nightly for a while now. Use it to charge an iPad or iPhone, Kindle, etc. Haven't seen this at all. But, for me, Apple's cables are usually the first things that go bad. But I haven't had my USB-C cables long enough to really know if they are as bad as the USB-A lightning cables.
I would have to try with my X though, since it mostly sits on a wireless pad instead of using a fast charge. (EDIT: I really should refresh before posting more often... masotime's response is better)
The iPhone is probably drawing too low of a current near 100%. As all lithium ion batteries charge rate drops precipitously near 100%, the iPhone is going to draw the least. The Anker's minimum charge threshold on the USB PD port is likely above the current over the iPhone so it shuts off before the iPhone is full.
Nice explanation. Do we know what any of these thresholds are? I can get one of those power transfer devices to check power draw.
That would make sense. The majority of my power banks - including Anker's - will not charge Bluetooth earbuds because the power draw is so low that the bank shuts off the charging.
I'm pretty sure the regular USB A ports likely have a lower threshold and will likely charge the iPhone to 100%. You could charge it to ~80% on the USB C and then transfer to USB A for the final 20%. Honestly, the time difference between charging at USB PD vs USB A on an iPhone isn't as big as iPad's so I usually charge my iPhones on regular USB A...
Hi guys, I just bought a 2017 9.7’ iPad. How long it takes to fully charge from 0-100% using the original cable and power charger?
Can I use my iPhone’s lightning cable to charge the iPad? I want to keep the cable that came with the iPad for future use.
Can I use my iPhone’s lightning cable to charge the iPad? I want to keep the cable that came with the iPad for future use.
with the one that comes with it, it is about 4-5 hours for me. using the new method above with the 30w charger and the USB-c to lighting cable I can do it in about 2 hours.
Anker now has fast-charging cables?

IGNORE - these are just USB-A.

I got the anker charger ( Anker PowerPort 5-Port USB C Ladegerät 60W Wandladegerät, 1-Port mit Power Delivery für Apple MacBook, Nexus 5X / 6P und 4 PowerIQ Ports für iPhon https://www.amazon.de/dp/B072K4TB67/ref=cm_sw_r_cp_apip_thdOXsGD7lAWk ) and i’m currently deciding if i should also buy the usbc to lightning apple cable for my ipad pro 12.9 first gen.
I read in ankers site, after i bought the charger that it is strongly recommended to use the regular usb ports to charge an ipad. Any new clues as to why would they say that?
And another question, do you think it would be dangerous to also charge an iphone 6 plus on the usbc port?
Btw thank you so much for your informative post, o.p. and everybody else.
Edit: read the whole thread, hadn’t realised that there are so many different models of this, so i added the exact product i purchased.

Would like to pick up another one of these for the house.
Does anyone know if Anker has released any new codes? Or where I can find them?
Thank you
Got this guy last week, and tested it with Iphone 8 Plus. and it does indeed charge fast. from 48% to 58% in 8 minuntes.

The 2017 iPad doesn't support USB-C PD fast charging, unless what you really meant to say is the iPad Pro.
EDIT: I realized you are not making any references to fast charging. IIRC the iPads come with 10W chargers... you may want to get at least a 12W one (most third party ones support this). Any MFi lightning cable should support 12W charging, whether it be on the iPhone or iPad.
Probably because of this review: https://www.amazon.de/gp/customer-r...ef=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B072K4TB67 ? The USB-C PD might not actually fast charge Apple devices. That would be strange, but I have had this experience before. However, I expected that Anker would have fixed that by now.
I would go to Slickdeals and set an alert for "USB-C PD", "USB-C Power Delivery"

Hi all! Just wanted to thank all of you for sharing all this good info. Thanks to your help, I was able to pick up one of these https://www.amazon.com/dp/B076K7VYRT/ref=cm_sw_r_cp_tai_Z9nIAb8DJJRE7 for $19, picked up an open box Apple USB-C to Lightning charger for $13, and fast charge my new IPP 10.5! I really was expecting to have to pick up one of the Apple 29W chargers, but this one works pretty well—I don’t have a way to measure the wattage or anything, but I was able to get more than 1%/min up to 50%.

non Apple chargers have abysmal failure rate. Online reviews say quite a bit. Apple is also using all sorts of tech to limit the usability of 3d party cables. quite a few devices (95% according to UL Europe) do not come close to providign the specific current regulation Apple asks for. Apple downright claims that they can damage devices and they do. Assuming they do charge, their life is terrible. Cables? apparently Ankers last one connector pull, weeks in many cases. Yet have had brush motor vacuumed Apple cables and they were not even scratched. only abusive armrest closing, -40 to +50 car temperature ever damaged one in 5 years. Finally, all 1-3 star anker type reviews mention the "angle" problem, and disconnecting. That is designed deliberately by Apple (open press) using hardware (chips and connector micor markers) software and industrial design to make these 3d party unreliable to stop working and not a chance electronpucing people..So the 49$ 2m usb c to lightning Apple cable is quite a bargain. Dragged their cables in snow, middle east desert and they are the best cables out there, for thheir devices, period. at times have used 3d parties (no Apple around) , and usually throw them after a few days when the first charge interruption occurs. have not dared even gift them.

as per my last post, they do indeed damage Apple devices, esp the batteries. Hence why apple introduced 3 years ago Charge blocking technologies, making steady charges with 3d party devices inefficient. hardware id and software do it for apple. these 3d parties kille people once in a while, but thousands of times more, devices.

About that charger causing my iPad to be less sensitive to touch: I did more checks and found out that my iPad was at fault too. I swapped for a new one and most of the touch issues were resolved.
The charger (currently just an Aukey wall charger) still give touch responses some delay but not to the point where it does not detect touches. My Aukey USB PD powerbank does not give this problem at all.

I will say on my Ankle charger with USB plus PD and four or six other ports, the USB port did after two months. I think they are sending me another. Too bad Apple just doesn't make anything like that!
I think you're veering too much into the other extreme here and missing the point.
Apple has the MFi program for third party devices that satisfy the quality requirements, so if there ever is a third-party MFi USB-C to Lightning cable, I can trust that the manufacturer (and Apple) has done their homework and it's going to be a quality product. If it happens to not have that certification but still fast charges, then the risk is up to consumer admittedly.
Chargers are another ball game entirely. The point of the USB-C PD standard (and indeed, Apple's wholesale adoption of it across practically all their devices save the iPhones and iPads) is an encouraging endorsement of a common industrial connector standard that supports the features that Apple wanted originally - reversible connectors, and support for high power delivery, high speed data transfer.
If a charger legitimately supports the USB-C PD standard (and I'll admit there have been multiple hiccups while the industry tries to adapt), I see no reason not to use it. There's nothing particularly magical about the manufacturing quality of Apple chargers. Although good, they are also known to have issues. See http://www.righto.com/2015/11/macbook-charger-teardown-surprising.html, which both supports and refutes your point (search for the heading "Problems with Apple's chargers") - showing quite clearly it's not as black-and-white an issue as you seem to suggest.
Has anyone had any experience with 3rd party PD chargers interfering with the Apple Pencil? I am trying to paint on my 2018 iPad Pro while plugged in to a 3rd party charger using a genuine Apple USB-c to lightning cable. The charger is an mBeat gorilla 3 port USB-c charger with PD. Is this a symptom of the charger not delivering a clean or steady current as I have read? I don’t know anything about electronics, sorry if that sounds silly. (edit: I read it in the article linked in the previous post!)
At this point I’m going to return it and get the Apple adapter, not being able to draw while it’s charging is a bit of a deal breaker.
The interference - in Procreate while fast charging - drawing straight lines, it acts as if the pencil is lifted sometimes

It also misses touches when I try to zoom or undo, and if I two-finger zoom it jiggles uncontrollably!
The charger
https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com.au/ulk/itm/142665201820
I bought this as it’s the one of the only ones available in Australia, and has interchangeable prongs for travel and additional USB-a ports. Too good to be true, I guess!
Thanks.

This is interesting. You're right that 3rd party chargers may not work as well as Apple's own charger, but I'm wondering if the Pencil will work at all when you're charging an iPad Pro. Do you have the charger that shipped with your iPad Pro? I'd suggest testing with that first to see if it works. If it does, then I think getting the Apple charger is a good bet.
Otherwise, I've generally noticed that charging the iPad seems to sometimes interfere with even the capacitive touch - probably because both are electrical in nature. I can't confirm it, but those are my impressions.
The pencil normally works fine while charging the iPP. I do it all the time while working.
