iPhone 6s Plus is supported with iOS 15, currently iOS 15.8.2, and no later.

If you have apps requiring iOS 16 or later, you will need a newer or new iPhone for newer versions.

An iPhone XR, iPhone XS, or iPhone SE 2nd, or later, is needed for iOS 17 and the upcoming iOS 18;

There is no software update because your iPhone is too old.

iOS 12.5.7 is the last version for an iPhone 6.

Good day I want software update to 16.12

to my apple iPhone 6s Plus

kind regard haipanda
