10 things you must know about the new iPhone 6

Apple Inc on Tuesday launched its biggest and thinnest ever iPhone in two sizes

Apple Inc, the Cupertino-based electronics behemoth, on Tuesday launched its latest version of the iPhone. The new phones are among the largest ever by the company, with a bundle of new features. Here's 10 things you must know about the new iPhone6 and the iPhone6 Plus
 

1. SIZE: The iPhone 6 will have a 4.7 inche-screen, while the iPhone 6 Plus will have a 5.5 inch screen. This is the first time that Apple has upgraded its screen size this much, but it still falls short of some of the Android phones and phablets available in the market. 
2. PRICE: In the US, the the iPhone 6 will retail for a base price of $199 with a two-year contract with service providers, while the iPhone 6 Plus will cost $299-$499, with the same carriers and contract terms. In India, it is expected that the iPhone 6 will retail for Rs 60,000 (16 GB, 4.7 inches) to Rs 85,000 (64 GB, 5.5 inches) since the Indian market doesn’t follow the contract model. Grey market prices are likely to command a 20% premium. 
3. WHEN: Pre-booking is expected to start in the US on Friday. Cook has not yet specified when actual deliveries will start. Either way, expect the new iPhones to be a major conversation starter if you are one of the early birds carrying one. Indian resellers say they have no information about when they will receive the phones. 
4. CALLING: Both phones will also have a wi-fi calling facility,, which means that you can make and receive phone calls if you are in a wi-fi zone and are not on a phone network, 
5. WEIGHT: At 6.9 mm for the iPhone 6 and 7.1 mm for the iPhone 6 Plus, these are the thinnest smartphones Apple has ever made, a point that Cook made quite early in his presentation. Thinner also means lighter, and perhaps this is a way to take on larger, clunkier Android-based smartphones
6. SAFETY: iPhone users have long suffered the vagaries of a super-delicate screen that would shatter even on low-level impact. Apple is hoping to win that love back with what it claims is a shatter-proof sapphire crystal screen. The screen will also be largely smudge-proof and water resistant. 
7. CAMERA: The older iPhones have also fallen behind in camera quality, with even lower-priced smartphones carrying much cameras of much higher quality. This time, the iPhone 6 hopes to change that with an 8 MP iaSight camera and a new sensor. 
8. BATTERY: Another sore point with earlier models, the new iPhone 6 will run on a non-removable Li-Po1810 mAh battery that should give users extended use-time. 
9. SPEED: Both models come with the fastest chip Apple has ever used. The new processor chips are expected to both speed up computing as well as preserve energy. The second point is important, since many iPhone users often use energy-hungry apps. The new chip should help in conserving battery power, too. 
10. DISPLAY: Both iPhones come equipped with Retina HD display for a clearer view. The new phones will come in multiple resolution options, with the higher end iPhone 6 Plus kicking in at 1080 pixels, but still falling short of the QuadHD level that some Android-based phablets pack.
