How to upgrade iPhone from iOS 15.8.3 to 16?

I have a iPhone 7plus so why can’t it go to ios16.0 instead of 15.8.3

Why? Because it is not compatible with iOS 16 and higher. You'd have to ask Apple for any official reason more detailed than that. But from what I can see in MacTracker, all iPhones that can run iOS 16 or higher have Neural Engines. Your iPhone 7 Plus does not have one. Those first appeared (in rudimentary form) in the iPhone 8 and 8 Plus.

In addition, you now need iOS 17.0 or better to run Netflix.

Which iPhone do you have? That will determine whether, and how far, you can update.

• If you have an iPhone 6s, 6s Plus, SE (1st generation), 7, or 7 Plus, then iOS 15 is the end of the line. To run newer versions of iOS, you will need to buy a new iPhone, preferably one compatible with iOS 18.

• If you have an iPhone 8, 8 Plus, or X, then iOS 16 is the end of the line.

• If your iPhone is more recent than that, you can update to the latest version of iOS – iOS 18. (See: iPhone models compatible with iOS 18 - Apple Support)

Your iPhone is too old for that.

You’ll need a newer (used, refurb) or new iPhone.

Any recent iPhone will be substantially more capable than an iPhone 6s.

The iPhone 6s originally shipped with iOS 9.0. It has gotten six major version updates, but iOS 15 is the end of the line. The iPhone 6s cannot update to iOS 16 or higher.

Which iPhone you have determines how far you can update. That is why, when you ask about how to update to a particular version of iOS, which iPhone you have is highly relevant. If the iPhone in question isn't compatible with the version of iOS in question, the answer to "how?" will be "you can't".

You can update an iPhone SE (1st generation) to the latest release of iOS 15. You can't update an iPhone SE (1st generation) to iOS 16, 17, or 18. For the iPhone SE (1st generation), iOS 15 is the end of the line.

If your iPhone SE (1st generation) is not already running the latest release of iOS 15, here is how you get there:

Update your iPhone or iPad - Apple Support

About iOS 15 Updates - Apple Support

Note that the iPhone SE (1st generation) originally shipped with iOS 9.3. If you are more than a couple of versions behind iOS 15, you may find that to get to iOS 15, you will need the help of a Mac or PC.

You can only update from an earlier version of iOS to iOS 16 if you have an iPhone 8, 8 Plus, or X.

Any earlier iPhone is not capable of running iOS 16, and will never be offered an update to it.

Any more tecent iPhone will be offered an update to something more recent, without the ability to pick and choose iOS 16 as an intermediate version.

Please iPhone 6s ios15.8.3

Nope.

You’ll need a newer or new iPhone.

These days, I wouldn’t go below iPhone SE 2nd, iPhone XR, iPhone XS, or later.

For an iPhone 6S, you can not.

That model can not be updated further.

It doesn't, in terms of running Netflix. iOS 15 is also the end of the line for the iPhone 7 Plus.

Your ability to buy a new phone really isn't a factor. What phone you own is. If it can't support iOS 16, then there's no help for you. That means in order to run iOS 16, you MUST own at a minimum an iPhone 8, 8 Plus or X. If you own an iPhone 7 or older, it CANNOT run iOS 16.

Try using the web version of Netflix.

Since the OP mentioned iOS 16 and Netflix, I'd though I'd note that Netflix recently changed the requirements to run their app. You now need iOS 17 or higher.

Re: “I also have this same issues here too I really need help cuz I don’t have any money to get a new iPhone”

If you have updated your iPhone as far as it supports, and that is not far enough, and you are not willing to buy a newer phone, then you will just have to put up with whatever limitations running the old version of iOS implies. Such as not being able to run the Netflix app.

Nope.

Netflix requires iPhone XS, iPhone XR, iPhone SE 2nd gen, or newer.
