Updating iPhone while in warranty

If you have an iPhone 7, it can’t be updated past iOS 15. The iOS version does not have any effect on the warranty. What phone do you want to update and what is your current version?

iOS updates do not void the warranty. Why would something Apple makes and provides themselves void the very warranty they offer?

Seems like some context is missing in your question.

What model of iPhone are you trying to update?

Is it a model that supports iOS 18.2?

Are you trying to update in some unsupported or hacked manner?

Updating to iOS 18.2 on supported models does not void the warranty.

An iPhone 7 would not have any warranty left on it at this point anyway.

You’re in good shape to upgrade your iPhone. The upgrade will not affect your warranty.

Update iOS on iPhone - Apple Support

An iPhone 13 can be updated to iOS 18.2 without any issue. It will not have any effect on the warranty.

If you have an iPhone 7......the product listed in your profile.......it cannot be updated to any iOS version higher than 15.8.3.

If iOS 18.2.1 is available for another phone that you have, you would want to update that phone to take advantage of the latest security updates. Updating will not affect your warranty one way or the other.

Is your iPhone currently covered under the Apple Original one year limited warranty or covered under Apple Care?

What iPhone model do you have and exactly when did you purchase it?

Up to iOS 18.2.1 as of yesterday.
