Technically no but apps and stuff take more resources over time so it will seem like a slower device because stuff is optimized for the newest devices

Yeah but that’s any device. You won’t notice it for quite some time though unless you’re doing comparisons side by side with the latest and greatest years from now.

No they don’t. Case in point: I saved an old iPhone X from being recycled last year. Perfect shape, battery health was 87% and it ran perfectly with no slowdowns. Latest operating system too btw. The 14 would last for years if properly taken care of and not loaded up with stuff (like if you loaded a 128gb phone with 127gb worth of stuff then you’ll see some issues). You’re good

Yes when the battery ages. Replace the battery and you are good to go once again!

I’ve had my iPhone 11 for almost 3 years now, at 82% battery health and it’s still fast like new infact.

No, they don’t.

Many people keep using their iPhones for 3, 5, 7 years or more.

No, the battery will have to be replaced though. Also some apps over the years have minimum requirements. Expect to get an easy 6 years of use if not longer.

No not iPhone, yea Samsung does BUT if it exynos, snapdragon is probably way better

Usually when battery health degrades apple throttles the cpu to prevent you from losing battery fast so just replace the battery when needed and the device will run you good for a long time

Any device slows down as the battery reaches the end of its life. When that happens just replace the battery.

Theres too many opinions in the chat. From research, this is the closest answer I have found over the years.

Yes, iPhones just like all other phones get slower over time. This is because hardware parts get used up over time such as RAM, SSD storage. But this aging is a bit slower compared to other things.

Two of the bigger culprits for slower phones is Software and Battery.

Battery: As you battery degrades and once it gets down to 80%, the phone is programmed by software to throttle the CPU thereby making the phone a bit slower to decrease load on battery and increase longevity. You can bypass this by getting a battery replacement.

Software: As newer softwares come out, they increase the load the phone is under in ways we don’t directly see. Newer softwares although made to be compatible with all phones that support it is still made at the end of the way after the thought of the newest phone. Since newer phones have much more powerful chipsets, they handle the background tasks and software better than older phones. Hence why if you get an iPhone 14 now, in 6-7 years, it may not be as slick and fast but it will still maintain somewhat of its original performance as best as possible. Will you be able to tell the difference? Not unless you compare your iPhone 14 to an iPhone 20 in 6 years running iOS 22

It’s the OS that would cause it to slow down.
