Why is my iPhone 6S won't keep on
After having a water-damaged, I went to the apple service, they cleaned the main board with special liquid, my phone can work again. After a week, my phone suddenly turned off, I charged it two days later and its working. Same thing happened again. I wonder if I should changed the battery because it is 60% when it went off, but it has no power when I try to charge it? I try to plug it in charging right away but it won't turn on, I have to wait at least a day after.
Or is it about the LCD cause the screen went blur before the phone turned off?
Your answer / help would mean so much to me, thank you in advance.
