I was beginning to think my 6plus was faulty. Whenever I held my finger in place the screen/cursor would wobble up and down (I say screen as I only hold the finger on when scrolling)

Turned out it only does it when I plug my phone into my old iPad 3 mains charger.. Which is 12W/2.4A - does anyone else's do that? It's fine when plugged into lower power blocks.

To show how bad it is - The lines along the bottom and top in the attachment there are steady slow horizontal swipes. Bottom with the high powered block and top with a lower one.

I just thought this interesting as a lot of people suggest using a higher powered charger to charge faster, but I've not seen anyone mention side-effects.. Does anyone else's do the same?

I've reverted to using lower power ones, don't want a repeat of the MacBook in my sig, haha.

which charger you use should make no difference as far as the screen twitching. I had seen this effect on my 6 a few times with it on no charger.

That's exactly it though. I know it shouldn't make any difference but it clearly does, easily replicable every time. It doesnt do the twitching at all unless it's plugged into that one charger - which strikes me as pretty weird. I just want to see if other people can replicate it if they have 12W chargers..

It doesn't do it if I plug it into a 10W one, only the 12W one, and it starts doing it as soon as its plugged in.

I guess I need to make a video of it, it seems pretty crazy.

Are you using the same cable and be same outlet with both chargers? To rule out that it's the cable or anything like that.

Sorry but it is not that strange.

Better things to worry about are there not? Or is this it?
Why is it not strange? And why wouldn't it be something to worry about on some level? There are always bigger things to worry about, but if we used that approach we wouldn't be discussing anything else aside from just hunger, decease, war, and impactful things of that nature. Ultimately petty much nothing brought up in these forums would make that kind of a cut.

Are you sure it's a genuine cable/charger as I've seen this with fakes but never with genuine

I have seen this behavior multiple times and it is not a sign that the world is ending. You are more than free to worry about it, pardon me while I do not.

I would love to be at the Apple Store when the OP explains it to the Geek. The look on the Geeks face will be priceless.

Who even mentioned anything close to the world ending? :confused: And I'm not even the person experiencing this, so I certainly don't have any worries about it at all. It's almost like we are reading different threads.

Umm, I'm not "worried" / but it would be nice to know if it's a common thing. And I thought others would find it interesting too. If a charger can interfere with the accuracy of the touch screen it could definitely lead one to think it's not good for the phone to use the charger at best, or possibly there's something bizarro wrong with either the phone or charger at worst.

Also it IS downright weird, if Apple are telling us we can use these chargers yet they do this to other people too, that's unusual and not very Apple-y.

I didn't seriously think the phone was going to catch fire (like my wife's MacBook did, lol) - the odds of that, after already experiencing similar are astronomically low. I'm still going to avoid using the 12w on this phone anyway - 10 will do.

Again, I never said the world is ending, haha. You know though? I think the geniuses would be pretty damn interested if they've not seen this behaviour before with a specific charger. They like you bringing this stuff up, like the time there was dust inside my iMacs screen layers and despite it being way outside warranty replaced the entire panel for free. I could likely get a free 12w charger out of this if I cared enough to do that.

Apple-y = "it just works" (in theory)

Apple-y does not equal .. "It just works as long as you don't plug it into a 12w charger, in which case it'll be inexplicably wobbly."

Would be nice if someone else could replicate it anyway, haha.
