Screen: The S4’s five-inch touchscreen is slightly larger than the Galaxy S3’s 4.8 inches. But it is substantially larger than the iPhone 5’s four inches.
The screen size alone will be a key benefit over the iPhone 5 for many business users. When you’re working with documents, databases, or taking notes, a larger screen is often easier to use, especially for touchscreen typing.
The resolution of the S4 display is comparable that of the iPhone 5’s Retina display. The S4 features a high-definition Super AMOLED screen, with a resolution 441 pixels per inch (ppi). Apple’s iPhone 5 Retina display has a resolution of 326 ppi.
Memory: If you need access to large files or lots of video, the S4 should give you more memory than the iPhone 5. Like the iPhone 5, the S4 comes with built-in memory options of 16, 32 and 64 GB. But the S4 also has a microSD slot that accommodates memory cards up to 64 GB. And you can carry as many of those around as you like.
Size: The S4 is thicker and heavier than the iPhone 5. The S4 weighs 130 grams and is 7.9mm thick while the iPhone 5 weighs only 112 grams and is 7.6mm thick. (But by contrast, Samsung’s Galaxy Note 2 phablet weighs a whopping 182.5g and is 9.4mm thick.)
