Apple is saying that the only thing that is changed is everything, but according to me they are saying this just because there is nothing more changed in this phone from iphone 6 plus.so first of all if you have iphone 6 plus then you seriously dont need to spend another 80 thousand for this phone.now if you dont have iphone 6 and planning to buy a new phone then this is the best phone.
The key new feature in this phone is 3d touch and improved camera which can now shoot 4k videos.this phone come with 12 megapixle camera.it has all new apple A9 chip and have 2 gb ram.this phone is ofcourse on ios platform and ios is better then android thats what I feel otherwise world is divided in 2 part about android vs ios.design of this phone is unmatchable and comes in 4 colors, space gray, silver, gold and rose gold.batery is 2750 mAh but the battery life is really great, dont go with mAh numbers.available in 16 64 and 128 gb and memory card is not supportable.on a down side it dont transfer files very easily so its very difficult to add music in phone or transfer photroes for iphone to other phone however now a days so many software are available for it so you cant cancel this phone just for music and pics, siri, voice assistant is really great and accurate.this phone is really easy to use and very stylish.ofcourse it is expensive and some feel it overpriced but thats what apple says, if it is not an iphone then it is not an iphone!
