Apple just announced its brand new iPhone 6, which Apple CEO Tim Cook called the “biggest advancement in the history of the iPhone.” Cook promised said, in addition to the iPhone 6 Plus announced, this is the best phone we’ve ever seen.

The device packs a next-gen “Retina HD” display, which uses ion-strengthed glass, an improved polarized, IPS liquid crystal and an ultrathin backlight. As expected, the iPhone 6 has a 1335 x 750-pixel display that measures 4.7-inches across and has a 326ppi. That’s 38 percent more pixels than the iPhone 5s offers. Additionally, it’s 6.8mm thin, much thinner than the 7.6mm thickness of the iPhone 5s.

It also offers a second generation 64-bit processor, Apple’s A8 processor, that’s 25 percent faster than last year’s chip and offers a 50 percent bump in graphics performance. The iPhone 6 should offer 50 hours of battery life for audio playback, 11 for video, 11 for Wi-Fi browsing, 10 hours of LTE browsing, and up to 10 days of standby time. Additionally, Apple is including a new M8 co-processor with a barometer for tracking elevation movements, like how many stairs you’ve climbed.

The phone also features a brand new 8-megapixel iSight camera with image stabilization (digital), improved face detection and more. It will start at $199 and launch on Sept. 19.
