The iPhone 4S is a good-looking piece of kit. I’m writing for a black model, but there is also a white model available.It still looks and feels expensive, and, while it's thicker than the newer iPhone 5c and iPhone 5s models, it's still only 9.3mm ( the iPhone 5s is just 7.6mm thick) . It does feel heavier though, at 140 grams.The iPhone 4S's has a 3.5in display. I find that the smaller display means the iPhone 4s fits in my pocket nicely, and is easy to carry around. Of course, there are disadvantages to having the smaller screen, but that’s not a big deal. The iPhone 4S has a complete glass back. The iPhone 4S 3.5in display is 960-by-640 pixels, with a screen resolution of 326 pixels per inch, making it Retina standard. The rear-facing camera in the iPhone 4S is an 8-megapixel iSight camera. It has an f/2.4 aperture and can shoot 1080p video. Apple's iPhone 4S is powered by an Apple-designed dual-core A5 processor. iPhone 4S can handle most of the tasks I want to carry out swiftly, but if speed is top of your priority list then the iPhone 4S probably isn't for you. Apple claims that the iPhone 4S provides up to eight hours of talk time on 3G, up to 200 hours on standby, up to six hours of 3G internet browsing or up to nine hours of WiFi internet browsing. But without doubt, iPhone 4S needs to be charged every day. Pros Cheaper than iPhone 5c, iPhone 5s Can run iOS 7 Cons Smaller display than iPhone 5c, iPhone 5s Poor battery life
