It's a phone that's in an identical chassis to the phones released three years ago, We can call it's the iPhone 'Special Edition'.
By launching a 4-inch phone, no matter how fancy the specs are, peoples will expect it to be a little cheaper, and thankfully that's what Apple has done. The SE starts at $399, which is the lowest introductory price Apple has ever offered on an iPhone. That’s for the 16GB model; the 64GB variant will run you an extra $100.
Besides price, the key selling point with this new phone is the design. The chassis, as I've mentioned above, is almost the same as on the iPhone 5S, and beyond coming in rose gold color, it doesn't offer anything new at all.
The phone is designed to be easily operated with one hand, the 4-inch screen sitting just at the edge of a thumb stretch, and Apple is banking on this fact keeping the handset current.
The power of the iPhone SE is something to uphold,- its as much as powerful as the iPhone 6S and 6S Plus with a new A9 chip, the M9 co-processor and 2GB of RAM.
The one issue I encountered with this phone was when watching movies. The Retina display can't even display the lower end of HD movies.The sharpness looked OK actually - better than I was expecting from the iPhone 5S.
Battery life is very impressive, especially when you consider there are only a few extra mAh added in here, from 1560mAh to 1624mAh, and with no increase to the size of the chassis at all, This is really really impressive feat and addresses one of the key concerns we had in the 5S. If you're upgrading to this phone from the iPhone 5 or 5S, you'll be in dreamland with the battery life, trust me.

iPhoneSE, A new model iphone with 4 inch screen, Apple is now picking up where it left off with 4-inch screens.
If you have held an iPhone 5S, you would know what you are going to get with the SE. It’s small, linear and familiar of previous phones. There are no other surprises.
But, When its comes about specs, Its technically an iPhone 6s internals in a 5S body.The latest A9 processor is there, as is an NFC chip for Apple Pay. But the battery, which is about the same capacity as the 5S, but lasts a lot longer. Really!
The rear camera is capable Live Photos and 4K video. The front facing camera uses Retina flash which lights up the screen in low-light situations, especially for selfies.
For the first time, NFC is introduced on a 4-inch phone from Apple, which means you’ll get Apple Pay on the smallest screen.
I think the major attraction is the battery life, which is on so good. I can go two full days with light-medium use on an iPhone 6S Plus, and I get the same from the SE.
If you have got an iPhone 6 or newer, then SE likely is not fit for you. Even with specs are almost being equal, the smaller screen is just harder to return to after you have gone with big screens. For the small crowd who really wish their iPhone 6 or 6s were smaller, then go ahead and get the SE. You’ll love it.

The iPhone SE is an exact clone of the older 5S. However, it is slightly slimmer and lighter. The comfort of a smaller phone is something only stubborn.
Talking about the display, Everything is looks good in the small screen with a resolution of just 1136 x 640 pixels. it is very crisp with good contrast and viewing angles. But, 3D Touch is absent in this.
The phone has the 12 MP camera of the 6S along with Live Photos support. The rear camera is capable of shooting 4K videos along with slo-mo and time-lapse videos, also there is a dual tone LED Flash at the back and on the front screen flashes to lighten selfies, like in the 6S.
The camera shoots photos good under good lighting conditions, but not under low-light with flash enabled. The images sometimes having more dots under low-light. While camera quality is good, it is not at par with the 6S or the older iPhone 6.
The device is smooth and there was no glitches in performance. you might thing its small, but it is not at all 'less powerful' than the 6S.
Overall, iPhone SE is a small but faster super horse.
