One reason among others why they should make the battery user replaceable.

Apple admits it slows older iPhones -- to prevent battery issues
The company says the practice deals with problems -- like unexpected
shutdowns -- caused by aging batteries or cold conditions.

Apple's iPhone 6 from 2014 includes software that makes it run slower but
also prevents unexpected shutdowns.

If you think your older iPhone seems to run slower, you're not crazy.
Apple on Wednesday said a software feature it released last year makes your
phone operate more slowly. But the slowdown is designed to help offset
problems with the aging lithium ion battery in your device. As batteries get
older, they don't hold their charges as well as newer batteries, and have
even worse problems when the charge is lower or the temperature is colder.
The aging battery means your phone could have trouble operating or might
unexpectedly shut down, like happened to the iPhone 6 and 6S last year. The
processors in those devices wanted to hit faster speeds, but the batteries
couldn't handle it, prompting some phones to simply switch themselves off.
To address that, Apple's iOS software, starting with last year's iOS 10.2.1,
included better power management capabilities. It will slow down your device
to prevent it from shutting down, but only in cases of cold temperature, a
low battery charge or very old batteries.
Last year's software applied to the iPhone 6 and 6 Plus, 6S and 6S Plus and
SE. This year's iOS 11.2 extended the feature to the iPhone 7 and 7 Plus. It
will be applied to other Apple devices in the future.
Apple said in a statement:
"Our goal is to deliver the best experience for customers, which includes
overall performance and prolonging the life of their devices. Lithium-ion
batteries become less capable of supplying peak current demands when in cold
conditions, have a low battery charge or as they age over time, which can
result in the device unexpectedly shutting down to protect its electronic
components.
Last year we released a feature for iPhone 6, iPhone 6s and iPhone SE to
smooth out the instantaneous peaks only when needed to prevent the device
from unexpectedly shutting down during these conditions. We've now extended
that feature to iPhone 7 with iOS 11.2, and plan to add support for other
products in the future."
The comment from Apple came in response to a report from earlier this week
from Primate Labs, the company behind the Geekbench processor benchmarking
software. John Poole, founder of the organization, said in a blog post that
as iPhone batteries get older and lose capacity, their processors slow down,
decreasing performance. Poole explained that users expect their phones to
perform the same regardless of how old the battery is, but his tests
indicated that wasn't the case.
iPhone users have long complained about their devices seeming to slow down
when new models are released. Some even believe that it's an effort by Apple
(and other tech companies) to purposely slow down or otherwise hamper the
performance of their products to get users to buy new models. Apple has long
denied this claim.
For some people, the solution to a slower, older iPhone may be updating its
battery instead of purchasing a brand new device. Apple charges $79 to
replace the battery of an iPhone that's no longer covered by a warranty.
