I have just updated my iPhone 6 plus to iOS 11.2.1 and it now restarts randomly.
I had a new screen, battery & power button cable a while ago but up until the update it was fine.
I have tried a different battery and screen but it is still restarting - sometimes 5 seconds after starting sometimes 15mins.
I have disconnected the power button cable and it still restarts
I have restored the iPhone but that didn't help
