It was noted that Safari on iPhone 4S with iOS 8.0 took about 2.16 seconds instead of 1.25 with iOS 7.1.2. The Mail app took 1.30 seconds instead of 0.91 seconds, while the camera app lagged only slightly with 1.8 seconds than to 1.5 seconds on iOS 7.
ArsTechnica also observes that the iPhone 4S is the device with the smallest screen to get the iOS 8 update, resulting in a cramped feel as the OS has been designed for the large screen iPhone 6 and iPhone 6 Plus with features like predictive typing, new Mail sorting options, Notification Center widgets, Spotlight and more. The team notes that only one of two results can be shown with Spotlight suggestions, while Notification Center can fit in a widget or two before users will start scrolling.
Notably, the iPhone 4S is the last device from Apple to have a 3.5-inch display, and it runs on the dated Apple A5 chip, while the latest iPhone 6 and iPhone 6 Plus respectively bear 4.7-inch and 5.5-inch displays while both running on the Apple A8 chip. Apple had launched the iPhone 4S in 2011.
While we are hopeful that Apple will address the issue just like it did with the quick iOS 7.1 update for the iPhone 4 last year, it would have to provide a rework of the UI to prevent the cramped interface on a small screen size.
