New features of iOS 8 that Apple declares as "the biggest version upgrade so far" Summary - GIGAZINE
◆ iPhone 4S
IPhone 4S is the oldest terminal among iPhones that can update to iOS 8. Although most of the features of iOS 8 can be used on such iPhone 4S, functions such as "AirDrop", "Touch ID", "Handoff function" and "OpenGL support" are said to be incompatible with hardware in 4S. Also, the iPhone 4S does not support LTE, and the performance of the Apple A5 chip installed in 4S is less than a quarter of that of 5s A7.

Ars Technica who measured the operating speed of iPhone 4S updated to iOS 8 has criticized "iPhone 4 updated to iOS 7 is bad". The figures in the following graphs took to repeat the operation of launching each application once on iOS 7 and iPhone 4S equipped with iOS 8, closing it when it became usable, and then restarting it twice It is a measure of time. Reaction time varies depending on the application, but in some cases iOS 8 takes twice as much time than iOS 7 to do the same operation. The browser benchmark test seemed to be slightly faster than 4S equipped with iOS 7, and there was no big difference in battery life.
However, the operation itself of the terminal itself seems to be very slow, Ars Technica writes that it is strange that iPhone 4S, which worked comfortably in iOS 7, will be delayed so far.
◆ iPad 2
Four features that can not be used even if updating iPad 2 to iOS 8 are "Apple Health", "Touch ID", "Handoff function", "OpenGL support".

The table below summarizes the results when comparing speeds on iPad 2 with iOS 7 and iOS 8, and you can see that the operation of iOS 8 is also slower than that of iOS 7 on iPad 2. In addition to this, the response of the screen rotation when holding the iPad vertically or horizontally is very slow, and there are things that other operations do not move smoothly in part.

However, Ars Technica describes that the actual feeling of use is slightly slower for iOS 8 than for tab reloading and character typing.
