"expect" is the keyword here. Speculation by some snews media. This is
not a statement from Apple and thus useless.

The product development of the X was done with knowledge of the
batterty problems for the 6s. So it is possible that it was fixed or
significantly reduced.

I think that's wishful thinking (sans facts) for two big reasons:
1. What you hope goes diametrically against what Apple actually said.
2. Apple didn't change their power-hungry single-threaded architecture.

Backing up those two facts is this recent article:
Apple Won't Stop Throttling iPhone Performance
https://www.extremetech.com/mobile/261243-apple-cuts-battery-replacement-costs-wont-stop-throttling-iphone-performance

That article clearly says Apple "won't stop" throttling of *all* newer
iPhones after about one year to about half their original CPU speeds.

Hence, the article makes the same claim that I do which is that Apple
iPhones effectively cost a *lot* more than just the sticker price:

"The effective cost of buying an Apple device is significantly higher
than it used to be, at least for people who keep their hardware more
than a year"

And, the article reiterates that Apple outright lied to its customers:

"Apple acknowledges that it failed to properly inform users about the
changes made in iOS 10.2.1 and the introduction of this throttling."

Interesting fact, since the Apple Apologists still deny what Apple already
admitted. Another fact that the Apple Apologists will hate is that this is
an Apple-only problem.

"Apple tries to dodge responsibility for its own smartphone designs"
"This is an Apple-only issue."

Everyone (but the Apple Apologists) already knew that this problem is an
Apple-created Apple-design problem, where *all* the major Android
manufacturers have gone on record publicy asserting

"Android phones do not perform this kind of throttling".

What's more interesting than that is where this article goes into decent
detail on the one thing that's different about Apple design:

"Single-threaded performance is the one area where Apple clearly
stands alone."

Interesting. The article posits that the Apple single-threaded design might
be the main reason why Apple batteries can't handle their phones:

"there's a strong relationship between power consumption and
architecture"

In summary, it's purely wishful thinking that Apple won't throttle *all*
their latest iPhones after one year because:
1. Apple themselves clearly said they'd throttle all their newest iPhones.
2. Apple didn't change their power-hungry single-threaded architecture.

Remember, this is an Apple-caused Apple-designed Apple-only problem,
despite nospam's clever hands-caught-in-the-cookie jar Apple Apologists'
attempt at saying Android manufacturers also *secretly*, *permanently*, and
*drastically* throttle CPU speeds of their phones after only one year of
ownership.

Everthing I state is a fact.
