Apple iPhone 4S
 |
Compared with the iPhone 4, iPhone 4S didn’t introduce so many changes. The device looks too much like the previous version, but it comes with a redesigned antenna which fixes the signal issues. The new antenna system consists of two independent antennas which allow the phone to switch between, thus preventing dropped calls. Iphone 4S has an improved processor- A5, thus the phone is more responsive that its predecessor. The screen is 3.5 inches with a resolution of 960 x 640 pixels and a 330 ppi pixel density plus the Gorilla glass coating. There are also some drawbacks. For example, the 4S has a worse battery life, so you will definitely charge your iPhone 4S more often that iPhone 4. At the same time, the new model introduces the improved 8 MP camera, which performs better than the 5 MP shooter available in iPhone 4. The new camera delivers sharper and brighter images and it allows you to capture videos at 1080p. Other features found on the iPhone 4S include an active noise cancellation microphone, SiRi natural voice assistant, iCloud service, audio / video player and photo editor, plus GPS support. Overall, this model is a refinement of the iPhone 4 with a faster processor and a better camera. |
