The new iPhone is very similar to its predecessor same shape , same size , how it looks how it feels is pretty same as iPhone 6 and 6 plus . But with improvements like antenna bands don't go across the back anymore gives neat and clean finishing . The two new colors are black and jet Black . Black is the matte finishing and jet Black is glossy black like a Piano which is also a finger print and scratch magnet .
iPhone 7 is very similar to touch track pad in new iPads it doesn't click anymore it is a solid glass button with pressure sensitivity which doesn't move .
#3: WATER RESISTANCE
iPhone 7 is now officially water and dust resistant it is rated to survive under 1 m of water for 30 min. So, now you can now take a shower with it .
The iPhone 7 has a new 12 mp camera with f 1.8 aperture , Optical Image Stabilization and couple of new things new image processing chip , quad Led flash and Raw capture which is really awesome and beautiful camera bump.There is also a new 7 mp front facing camera which looks better from the previous one .
The real camera upgrade is in the bigger phone (iPhone 7 plus) which has these two 12mp camera with different lenses in front of each on right is had 28 mm lens and on left 56mm (2X) lens this is better for portrait and objects which are far away .
iPhone display is mostly same as the iPhone 6 same resolution and same IPS technology but it is 25% more brighter with more color gamete so the colors will pop up more but probably not like a OLED.
I would say that it is not a proper stereo but technically it is .The bottom of the phone has one speaker grill it is downward facing and the earpiece is the other side of the pair and it is front facing it is weird but technically it makes stereo speaker.
Every iPhone7 and iPhone 7 plus will ship with this lightning earpods because there is no headphone jack in the iPhone 7 but iphone will also ship little adapter with every phone.
The apple has introduces the option of wireless earphones , which they call Airpods. they come is charging case which charges then and when the case is opened it automatically connects to the iphone the airpods also got proximity sensors so when you put it in you ears it will start playing song . There is one more feature double tap on earpiece will activate siri ,So, you can talk with its both eand microphone.
It is the minor one . Apple has released a smaller update to use apple pay in JAPAN.
iPhone 7 has the new A10 fusion chip inside which has few benefits that better performance with CPU and better GPU performance for better gaming and it is Quad-core chip with two of it core being lower powered So, in theory it is more efficient chip which will give you more battery life.It starts with 32 GB version and goes up to 256 GB version.
