I have acquired an iPhone 6plus with 2 problems. 1st. looks like touch disease, but I'm not 100% sure. Screen does not respond to touch after 30 min of use. No grey bars at the top and bending frame slightly does not effect making it work. 2nd. The battery takes a long time to charge. It will say 100% then after 15 to 20 min it says 40%. Then it starts discharging down faster then it should. Where should I start with these 2 problem? Any help is much appreciated
Try a new screen and a new battery to see if the symptoms are the same.
I should have stated that to start with. I have already changed both the screen and battery.
Well, most likely it's the touch chip and possibly a charging chip issue. If you have a tristar tester, then it'll tell you for sure. It could also be a charge port issue or maybe battery connector.
I don't have a tristar tester. I can check the battery connector to start with. Thanks.
When looking at the battery connector, check the middle pins, which are the "switch" pins that relay the battery info to ios.
