Phone died, went black. Won't turn on
I have an iPhone 6 plus that was working fine. It was low on batteries so I went to charge it. After returning to my phone, it wouldn't turn on and is completely dead. I went to check to see if it was battery, still didn't turn on, replaced screen, still no luck, replaced charger portal, still no luck. The guy helping me with my phone says that it probably internal. Can this still be fixed with it having to go to apple store?
Is this a good question?
