Design and Display

The iPhone 4S has a similar design to the iPhone 4, with a 3.5-inch Retina display, stainless steel frame, and glass back. The iPhone 4S is available in black and white.

The iPhone 4S's display is sharp and vibrant, with excellent viewing angles. The display is also very responsive, making it a pleasure to use for tasks such as typing and gaming.

Hardware and Performance

The iPhone 4S is powered by the Apple A5 processor, which is twice as fast as the A4 processor in the iPhone 4. The A5 processor makes the iPhone 4S feel much faster and more responsive than its predecessor.

The iPhone 4S also has 512MB of RAM, which is double the amount of RAM in the iPhone 4. The extra RAM helps to ensure that the iPhone 4S runs smoothly even when multiple apps are open.


The iPhone 4S has an 8-megapixel rear camera with a f/2.4 aperture. The camera takes sharp, clear photos in good lighting conditions. The camera also has a number of features, such as autofocus, face detection, and panoramic mode.

The iPhone 4S also has a VGA front-facing camera for video chat. The front-facing camera is not as good as the rear camera, but it is good enough for video chat.


The iPhone 4S runs iOS 5, which is the latest version of Apple's mobile operating system. iOS 5 is a major update that includes a number of new features, such as iMessage, Notification Center, and Passbook.


The iPhone 4S's most significant new feature is Siri, a voice-activated personal assistant. Siri can be used to perform a variety of tasks, such as making calls, sending text messages, setting alarms, and getting directions.

Siri is still in its early stages, but it is a very promising feature. Siri is accurate and responsive, and it can be used to do a variety of tasks without having to touch the iPhone.

Battery Life

The iPhone 4S has a good battery life. The iPhone 4S can easily last a full day on a single charge, even with moderate use.


The iPhone 4S is a great phone. It has a sharp display, a fast processor, a great camera, and a number of new features. The iPhone 4S is a great choice for anyone looking for a new smartphone.

However, the iPhone 4S is starting to show its age. It has a smaller display than newer iPhones, and it does not have some of the newer features, such as a fingerprint sensor or a dual-camera system. If you are looking for the latest and greatest features, you may want to consider a newer iPhone.
