The iPhone 4S’ performance is extremely disappointing at best – you get to “experience” choppy frame rates as well as a higher level of pixelation in the animation. There will also be less detail compared to what the iPhone 5c is capable of churning out, going to show that the threat of something getting outdated is very, very real, and it happens all too quickly.
Things are not going to get better too, when iOS 8 begins to ship later this fall alongside the purported release of a next generation of iPhones. Basically, legacy handsets do not get too much love and attention from developers, so, you might want to start saving up now for the new iPhone 6 or whatever it is going to be called when it arrives.
