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.
