UPDATED METHOD (in bold)

-Ground the iPad by touching it to a metal surface for 30 seconds
-Discarge your iPad charger by touching both prongs to a metal surface for 30 seconds
-Make sure your charger isn't dropped, shaken, or damaged
-USB C 30 watt chargers are unreliable

My iPad Pro 10.5” started studdering and having unresponsive touches for a long time. Then I switched to fast charging (usb c pd) and then noticed the problem getting worse. I noticed a direct correlation when i was charging and using the device at the same time.

SOLUTION
Use a reliable charger 12-15 watts (no usb c pd) and make sure it wasn't dropped!

I charge my iPad Pros (11” and 2018 12.9”) exclusively using USB-C PD, and use them while charging. I have no touch or stuttering issues.

Charging does affect iPad touch problem but using different chargers doesn't fix it 100%.

The problem with unresponsive touch is indeed a hardware problem connected to static electricity and Apple poor manufacturing process for all the iPads. So probably increased wattage affects that area. But the issue always comes back again. Also what helps is turning off rotation detection, but again it doesn't fix it - only improves a little bit, unfortunately :(

It takes a couple of full charge cycles from a working reliable charger to get your device working properly.

Respectfully, that is not the case. If you read through the many threads here and elsewhere on the Internet you'll find this "charger" fix has been proposed before and it is not actually a fix.

The charger must not be a fast/quick charger. Fast charging is not stable and will ruin your device. You have to do full cycles on a 12-15 watt usb a charger in order for the iPad to work normal.

How long does it take to ruin it? I've used a fast charger for my 10.5 iPP for almost 20 months now without a problem. Absolute statements like "will ruin your device" are simply not true.

Look at apples fast charger it was changed from 29 watts to 30 watts. Also look on the apple website go to iPads then go to accessories. You cant find anything other than a 18 watt usb c fast charger. Fast charging has no standards and can ruin your device. If your using a fast charger than anything from no response touches, greatly reduced battery life, and potentally ruining your devices charging ability.

There are fast charging standards -

I think he means possessive "iPad's touch", as in (emphasis mine):

No offense, but the more you write the more I'm convinced you're just making this up based on conjecture.

USB does have standards and the newer standards actually negotiate charging rates. I have a ~65-watt charger I got with my Lenovo laptop. I use it for charging multiple devices: the laptop it came with, my Surface Go tablet, etc. The laptop itself supports rapid charging.

Just because Apple re-works their product line-up doesn't mean there's a conspiracy. In fact you can take a MacBook Pro USB-C charger and plug it into an iPad (2017 and earlier with USB-C to lightning cable, or 2018 with USB-C to USB-C cable) and it charges just fine.

And for the record, I never used a high-watt, rapid charger on my 2017 12.9" iPad Pro and have pretty significant touch screen issues, so that kind of kills your hypothesis.

At this point you're really just spreading FUD. Fast charging absolutely has a comprehensive standard, it's known as USB Power Delivery. Find out more at https://www.usb.org/usb-charger-pd

Those articles describe a bunch of issues that are completely not-applicable if you buy a quality charger from a reputable provider. If you're purchasing first-party from Apple you're fine. I usually use first-party or chargers from companies like Anker. Both of which adhere to USB specifications. If you're buying some cheap charger from China off Amazon then you can expect it not meet the proper requirements. This isn't an issue with the iPad, nor with its ability to charge. It's an issue that when you're buying power supplies for electronics you shouldn't buy cheap. The same can be said for many things: I don't buy cheap surge protectors or UPSs, either. However, I have been know to eat a few no-name brand potato chips. The issues you are describing are not related to the issue as it is being discussed in this thread.

I use Anker chargers with Apple cables. No issues, ever.

The iPad regulates itself and will only take in a certain level of power. You can use a 60W charger or more and it will not blow anything up.

And the touch response issue has nothing to do with charging. I have a 12.9 and a 9.7 Pro. Both are charged with the same 29W Apple charger. Only the 12.9 has response issues. 9.7 is fine.

I asked Juli to write an article about it last year. It ended up being a software issue for many of us related to the Apple Pencil. It was registering fake inputs which would make it stutter and stop responding.

They fixed it though. It isn’t always hardware.

Maybe you're right, but I've heard a couple of people here were saying that charger affected the unresponsive touch problem making it worse. I cannot be sure, the problem is so random and unpredictable but it seems my iPad as well becomes much more unresponsive when connected to a charger (no matter what the charger is). But maybe I'm wrong. Still hoping that Apple's hardware engineers admit the problem one day and explain what they did wrong.

I had a 2017 12.9" that had touch issues when charging. I would usually just pull it out and it would be back to normal. None of the 2018 iPad Pros I now own have touch issues.
 
Make sure to ground the iPad by touching it to a metal surface for about 30 seconds. Also make sure to discarge your iPad charger by touching both prongs to a metal surface for 30 seconds. You guys this is how you solve the touch issues

*Make sure your charger isn't dropped, shaken, or damaged*
*USB C 30 watt chargers are unreliable*

Sorry no, that doesn't fix anything permanently. People did it many times, switching chargers, using genuine/non-genuine, switching cases - etc. It's a hardware problem with the iPad, it just stops working over time. All solutions are temporary.
