What’s this? The second one coming of the iPhone 4? Sure enough, Tim Cook just pulled the covers off of the hotly-anticipated iPhone 4S here in Cupertino. At the outside the 4S looks exactly like its predecessor, but at the inside it’s “all new.” Apple has jammed a dual-core A5 CPU inside alongside a brand new dual-core GPU that supposedly boosts graphics performance by as much as 7x. Up front is a similar Retina display we’ve all come to understand and love, and a pitcher back. That antenna round the sides (which caused many users a lot trouble) was revamped and might intelligently switch between two different sets of anntenae at the fly to bypass dropping calls according to the way you hold it. Those antennas are connected to a dual-mode GSM and CDMA radio that may let Apple’s handset roam the globe while enjoying either 14.4Mbps HSPA+ or EVDO.
At the back also is a brand new camera that sports an 8-megapixel camera with a backside illuminated CMOS sensor for better low-light performance. The lens now comes packed in a brand new assembly with a hybrid IR filter and sports apertures right down to f/2.4. The enhanced visuals extend to video performance in addition. The 4S can record 1080p video and has a brand new image signal processor for image stabilization and facial recognition, making the handset’s camera akin to many point-and-shoots. The camera is additionally rather a lot faster than many other smartphone shooters, needing only one.1 seconds before being able to take the primary shot and only half a second between successive images.
The 4S can be the primary Apple handset to return packing Siri virtual assistant tech baked in.
So far as battery life, you are looking at eight hours of talk over 3G, and 14 hours of 2G, while web browsing over 3G cuts off at six hours. Using WiFi you will get a decent nine hours of web, video playback tops out at 10 hours and music at 40 hours.
