Q: Iphone 6s OS update

Thanks Max, I have tried the soft reset several times, which initially solves the problem, but then a day later it turns itself off again. I have been to an Apple Store and spoken to the staff, who verified that several people have complained of identical issues since updating their OS, but only IPhone 6 users. Other than that they weren't helpful at all, suggesting I use the forums to find an answer.

I shall try one of the other suggestions offered and see if that helps

THanks for your help

Yes max, the link you sent me suggested several ways to alleviate the problem. The first way being to perform a soft reset, I have tried this, and it has had no effect. I think iam going to take the phone back to Apple, and insist they resolve the issue, after all, the OS update was issued by them, and the phone is under warranty.

Thanks anyway
