How to update my iPhone 6 to iOS 15?

NO. Not possible. As has clearly been stated in this thread, if you need anything higher than iOS 12.5.8 then you MUST accept it's time to retire your nearly 10 year old phone and buy a newer, more modern iPhone.

I want my to update

No update to iOS 13 or higher for the iPhone 6.

Wanting to update the version of iOS on the phone won't change that. The iPhone 6 originally shipped with iOS 8, which implies that it got updates to iOS 9, 10, 11, and 12. That's the end of the line for the iPhone 6.

If iOS 12 is now too outdated for the apps you want to run, what that tells you is that it is time to buy a new phone.

My ios 12.5.7 is need to update can you help me?

There are no more updates for the iPhone 6. You need a new phone.

You need an iPhone 7 to run iOS 15

You need an iPhone 8 to run iOS 16

You need an iPhone XR or higher model to run iOS 17

What does that even mean? If you have an iPhone 6 and you need anything higher than iOS 12.5.8, then you need to retire your 10 year old iPhone and buy a newer, more modern iPhone.

An iPhone 6/6 plus can't be updated beyond 12.5.7, it doesn't have the hardware required to run anything higher.

If you need a higher iOS version, you will have to purchase a newer phone.

• If you have an iPhone 5S or 6/6plus, the highest you can update to is 12.5.7

• If you have an iPhone 6S through 7, or SE 1st generation, you can update to 15.8.2

• If you have an iPhone 8 or X, you can update to 16.7.7

• If you have an iPhone SE (2nd generation or later), or XR through 15, you can update to 17.5.1

There are 5 pages in this thread that all say that the iPhone 6 cannot be updated to iOS 15.

iOS 12.5.7 was the last and final update for the iPhone 6. No more updates.

If you want to run iOS 15, you will need an iPhone 7.

If you want to run iOS 16, you will need an iPhone 8.

lobsterghost1 provided the answer in the post immediately preceding yours:

"Did you read this one page thread? If you did, then you already know the answer. If you have an iPhone 6, you don't update to iOS 15, because you CAN'T update an iPhone 6 any higher than iOS 12.

Buy a newer phone if you need iOS 15."

That answer is not going to change.
