Iphone11 asking if I need to update mu phone to ios18?
Does Iphone11 safe to update into ios18?
iPhone 11, iOS 17
It's probably safe, yes. But if there's nothing in iOS 18 that you're anxious to have as a feature, there's no need to rush to update. I would, however, recommend that you at least update to iOS 17.7 which should also be offered in Software Update on your iPhone. That update includes some important security updates.
Regards.
