I have to disagree with this statement - I p@sted the following questions recently and &oranges d3l3t3d all of them from my account:

All your previous questions referred to using iOS 26.2.1, where you should have seen the response to update to iOS 26.3, but you never responded.

  • Have you updated yet?
  • Have you performed a Force Restart to clear caches and do some basic housekeeping?

I thought I could opt out of upgrade to ios26


You can stay on iOS 18.7.2 or update to the latest version of iOS 26 – but Apple won't allow you to update to iOS 18.7.3. Apple's release notes first indicated that 18.7.3 was available for the iPhone 11 and later – but Apple then changed the notes to say that 18.7.3 is only available for the iPhone XS, XS Max, and XR (and some iPads).


I took same option with last month's security update but it's not offered just the new 26


Same here. Your choice is to update to iOS 26 or to live without the security updates that are in 18.7.3.


battery is 88 health in 1 yr
26 AI may finish off my little iPhone SE3
with 15 chip


There may be other artificial intelligence / machine learning features in there, or other things that eat battery, but for your iPhone SE (3rd generation), Apple Intelligence isn't going to be one of them. Your phone does not have the hardware to run it either under iOS 18 or under iOS 26.
