The battle between high-end smartphones is getting hotter by the day, with two most talked-about phones being Samsung Galaxy S2 and Apple iPhone 4S. Both the phones promise blazing performance but there still could be some differences between the two that could influence consumers when it comes to choosing one.
Apple Inc. unveiled the iPhone 4S, instead of the eagerly-anticipated iPhone 5, on Oct. 4. As it turned out, the smartphone featured some important upgrades that were rumored to be a part of the imaginary iPhone 5, like the 1GHz dual-core ARM Cortex-A9 processor, PowerVR SGX543MP2 GPU, an Apple A5 chipset and a 8-megapixel camera. It also has a 3.5-inch TFT Retina multi-touch display and is loaded with the latest Apple operating system iOS 5.
However, missing were prominent specs like edge-to-edge design, a larger display, 4G LTE and Near Field Communication (NFC) technology. It also comes with alternating antennae for better call reception, CDMA and GSM support, a personal assistant called Siri, iCloud and Bluetooth 4.0 wireless technology.
The Apple smartphone has a Li-Po 1,420 mAh battery, with 8 hours of talk time on 3G networks and up to 14 hours on 2G networks (GSM). With a two-year contract, the iPhone 4S costs $199 for the 16GB model, $299 for the 32GB model and $399 for the 64GB model. Apple-listed prices for a contract-free phone in the United States are $649 for the 16GB model, $749 for 32GB and $849 for the 64GB.
