The iPhone 6S is the successor of the Apple iPhone 6, which was the first iPhone to feature a screen larger than 4 inches, and offers the same beautiful and high-end experience as all of the Cupertino company's iPhone devices.
The iPhone 6S has a 4.7-inch LCD display that is extremely strong thanks to the sapphire crystal used in the glass, and also in the iconic home button. There is a fingerprint sensor on the home button for added security and automatic payments in the iTunes app store. As usual, Apple is offering a design that feels extremely premium, with a metallic construction with a focus on the smallest of details, something that is unmatched by most popular smartphone makers.
The iPhone 6S also comes with a camera upgrade for the first time in years, giving users a 12-megapixel camera over the 8-megapixel camera featured on previous iPhones. It incorporates Apple's iSight technology for taking the best pictures automatically without the need for custom controls and settings. Low-light imaging is a charm thanks to the large pixel size, and even photos taken with the LED flash come out naturally with the dual-tone flash technology. Also, on the front, there is a 5-megapixel Face Time HD camera paired with a retina flash.
The phone is powered by the new Apple A9 chipset. It's only a dual-core processor but still offers high performance that matches those provided by the quad-core and octa-core processors used by other phones. The CPU is 64-bit-enabled, allowing it to run apps a tad faster than 32-bit devices. Like the camera, the RAM has also gotten an upgrade, with the iPhone 6S now featuring 2GB of RAM for even better multitasking than before.
The iPhone 6S runs iOS 9, an operating system that might not be as flexible as Android but offers the most consistent and easy software experience to everyone. Everything runs smoothly, the OS has amazing animations that make you want to cruise around the interface, and all in all, the iPhone 6S is yet another step forward in Apple's hold on the smartphone market.
