iPhone 6 Randomly Restarts while in iOS
So i got an iPhone 6 from my brother that i was going to restore and use (im currently rocking the 5C and i had some of the parts laying around for one anyways). I knew it had VERY little water damage but it still powered on and worked while he used it until he dropped it and obliterated the screen. Before i bought the parts i saw it would randomly restart so i bought a battery along with the screen thinking it was a battery problem. As of now it has a new body, screen, charging port, and battery and it still restarts. Ive updated it and factory reset it and it still restarts. Now to explain my title, while it’s on and running iOS it will restart but if its Updating, Restoring, in Recovery mode or DFU Mode it’s normal and doesn’t restart. Everything is pointing towards it being a software issue but not at the same time. I’ve never seen an issue quite like this before. What kind of hardware issue would make it restart only when iOS is running?
Note: i posted this question on Apple Community and they said i should just take it to a Genius Bar and have them look at it but i feel like theres something im missing that i can do myself.
Questa è una buona domanda?
