iPhone 4S

iPhone 4S is a touchscreen smartphone developed by Apple Inc. It is the fifth generation of the iPhone and succeeds the iPhone 4 as the latest model of the iPhone. The design is identical to the iPhone 4 but with improved hardware specifications. It will be released on October 14, 2011, in the United States, Canada, Australia, United Kingdom, France, Germany, and Japan after being announced on October 4, 2011 at Apple's "Let's Talk iPhone" event at the Town Hall, 4 Infinite Loop. For the first time, the iPhone 4S will also be available for Sprint customers.



]History


Early studies and rumors


According to a Wall Street Journal report, American telecommunications company Sprint Nextel committed $20 billion to gain rights to the iPhone. Rumors have surrounded the next-generation iPhone for about a year and a half, now, and most rumors point to the new device having a bigger touch screen, better antenna and an 8 megapixel camera. According to the website for the Apple Store in Ginza, Japan, the iPhone 4S will be released on October 14.




Features


Hardware changes


Processor, memory, and storage


The iPhone 4S has the dual core A5 processor, that is also used in the iPad 2, and sports a dual-core PowerVR SGX543 graphics chip. The RAM has also been upgraded from 512MB from the iPhone 4 to 1GB. Storage size remains the same at 16GB and 32GB, however a larger capacity has also been added (64GB). The screen is the same as the previous generation's iPhones; 3.5 in, 640 x 940 resolution.




Antenna


The iPhone 4S' antenna has been slightly changed from the iPhone 4, and can now automatically switch antennas to attempt to provide the best signal as possible. Download speeds can now go up to 14.4Mbps, however it is not 4G LTE; it is HSDPA.




Camera and photos


The camera on the iPhone 4S is significantly improved--30% sharper, with an aperture of f/2.4, a third quicker to capture images, with an 8 megapixel sensor that takes 3264 by 2448 pixel pictures. It's also capable of HD 1080p video with video stabilization. Video and photo editing is now available on the iPhone 4S and in iOS 5 with features such as crop, auto enhance, and red eye reduction. Taking a photo can now also be accessed via the lock screen by double clicking the "Home" button, within 1.1 seconds. The volume up button can now also be used to take a photo on any device using iOS 5.




Voice control (Siri)


The iPhone 4S introduced a new automated voice control system called "Siri" that allows the user to give the iPhone commands, which it can execute and respond to. For example, iPhone commands such as "What is the weather going to be like?" will generate a response such as "The weather is to be cloudy and rainy and drop to 60 degrees today". These commands can vary greatly, and control almost every section of the phone. The commands given do not have to be specific; and can be used with natural language.




Power and battery specs


200 hours standby time (iPhone 4: 300 hours), 8 hours talk time on 3G (iPhone 4: 7 hours), 6 hours 3G browsing and 9 hours Wi-Fi browsing (iPhone 4: 10 hours).
