However, the company does admit that new iOS updates can put more demands on older hardware, and newer apps might not run as smoothly on older iPhones - in other words, the same amount of CPU and GPU power is available, but apps begin to suck up more of it, leaving you staring at loading screens.
Apple has released a new set of emojis - which includes Scotland's Saltire flag - as part of the technology giant's latest software update. The story was based on Google search data which showed that inquiries for "iPhone slow" increased hand-in-hand with the launch of each new device.
However, the best thing about the apps is that they allow you to download movies and TV shows so you can watch them offline anytime, without the need of Wi-Fi or data connection. Then they averaged the performance of the processor and the graphics chip once a month for 18 months from April 2016 to September 2017.
The researchers found that there was some very minor fall in the performance of the phones' CPU over time. And as for iOS 11, Apple doesn't roll out an update before testing on all devices alike. The update also brings 3D Touch Multitasking back to iOS devices.
My iPhone 6s Plus is still performing as well as I want it to, despite the fact that it's a two-year-old device. Of course, newer models will be faster and more efficient than older ones, but in reality, your old iPhone is no slower than it was before the new one was released. There's also the psychological effect of being aware of a flashy new iPhone out there which makes a person's current one look and feel outdated. However, what caught our attention and the attention of many other users is the inclusion of the Unicode 10 emoji.
In addition to this, the company touts that the operation has been successfully achieved with the use if the ReplayKit platform in iOS 11.
It might be that older phones are less compatible with the design of apps that update when a new version of iOS comes out.
A new report from benchmarking firm Futuremark found that Apple did not intentionally degrade the performance of older iPhones to encourage users to buy a new one.
