Check iPhone type & iOS version -> Go to: Settings -> General -> About.

If it is an iPhone 6 Plus -> iOS 12.5.5 is the last security updates for iPhone 6 Plus, -> released 23 september 2021.

 

If it is an iPhone 6S Plus you can update the iPhone to iOS 15, see this Apple article:

iPhone models compatible with iOS 15

iPhone models compatible with iOS 15.4 – Apple Support (UK)

 

Go to: Settings -> General -> Software Update.

See the following Apple articles:

You need about 7 GB device storage and good Service & Wi-Fi.

For reference...

Updating an iPhone:

How to do so...


A. Verify Compatibility:

Identify your iPhone model. The first thing that comes to mind in incompatibility being the culprit. So, confirm the model of your iPhone. If iPhone model is incompatible with iOS15 then it is because you iPhone does not meet the hardware requirements for this iOS version(s).


B. If Compatible...


1. Back Up First:

IMPORTANT: If you have an option to update, however, then be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the update


then...


2. Proceed with the Update:
