Among the differences: the symmetry of the bottom end. The devices are available in 3 traditional colors: "Silver" (silver), "Gold" (gold), "Rose Gold" ("Rose gold"), as well as in two new black options: "Black" (matte black) and Jet Black. In March 2017, as part of the charity campaign (RED), a version in bright red was presented.
In the iPhone 7/7 Plus, the mechanism of the "Home" button has been changed, unlike previous models, it has lost the pressing mechanism and has become fully touch-sensitive and sensitive to pressure; tactile feedback when pressed is provided by the vibration of the phone - the so-called "haptic feedback", implemented with the help of Apple Taptic Engine... The system "3D Touch" from.
iPhone 7/7 Plus also lost the analog TRRS mini-jack (3.5 mm) for connecting headphones. The manufacturing company suggests either using headphones with Lightning digital output, or go to wireless headphones AirPods based on the Apple W1 chip, or use adapters from Lightning to TRRS (the simplest $ 10 adapter comes with the phone, adapters are available that allow you to charge the smartphone while using the headphones).
iPhone 7 is protected from dust and water at the IP67 level (with use, the degree of protection may decrease), which corresponds (if the operating conditions are observed) to complete dustproofness and protection from short-term immersion in water to a depth of 1 m. as before, are not covered by the warranty.
The two iPhone 7 models differ in size, screen resolution, and number of cameras. Standard model iPhone 7 has a display with a diagonal of 4.7 inches, a resolution of 1334x750 pixels; phone dimensions - 138.3 × 67.1 × 7.1 mm, weight - 138 grams. Enlarged model iPhone 7 Plus Uses a 5.5-inch 1080p display phone dimensions - 158.2 × 77.9 × 7.3 mm, weight - 188 grams.
Both models use a front FaceTime HD camera with a new 7MP sensor and a main iSight camera with a 12MP sensor. IPhone 7 Plus has an optional 12MP main camera with a telephoto lens with a fixed 2x optical zoom.
Phones are equipped with built-in flash memory with a total capacity of 32 (except for the glossy black model "Jet Black"), 128 or 256 GB
Rivalry is the main determinant of progress. The race for profit provokes the development of all new technologies. This is why most large companies invest millions of dollars to improve their products. Thus, on the modern market every day more and more new products with improved characteristics appear. These processes have not spared mobile phones either.
So, Apple recently presented new flagship in the world of mobile devices - which naturally has its competitors:
- Sony Xperia Z4 and X;
- Htc one(M9);
- Xiaomi Mi5;
- Huawei P9;
- OnePlus 3 is a flagship killer.
To understand what exactly we are losing when buying a "seven" is possible only by examining in detail all the pros and cons of other top-end phones.
Feature Sony Xperia Z4 and X
The Sony company dates back to the distant 1946, when Akio Marita and Masaru Ibuka founded Totsuko in Tokyo (as Sony was formerly called). Since, this organization is developing rapidly. One of her latest inventions is a series of mobile Xperia phones Z4 and Xperia X.
Xperia Z4
The Xperia Z4 is an older creation than the Xperia X. Runs on Android Lollipop and Qualcomm Snapdragon 810. The size of the display is 5.4 inches at a resolution of 2560x1600. The RAM is 4 GB, while the permanent memory is 32/64 GB. This series stood out with an amazing main camera with a resolution of 20.7 megapixels. Front-camera more familiar - 5 megapixels. ICE flash, of course, is present.
Xperia X
Xperia X - latest development with phenomenal characteristics. The first thing that catches your eye is the camera. It even surpassed the previous model, accumulating as much as 23 megapixels. The front camera is also not left behind - 13 megapixels (a special offer for lovers of "selfies" and video conversations). Shooting has Full HD resolution, at a frame rate of 60 / s. Plus, phase focus allows for perfect shooting of dynamic objects.
Also, this smartphone is armed with:
- 6 nuclear processor Qualcomm Snapdragon 650, clock frequency which is 1.8 GHz (you can safely install demanding games and programs);
- memory capacity - 64 GB, which can be increased using micro SD up to 200;
- operating system Android version M (6.0).
As for the battery capacity, its capacity is 2620 mAh, which is not the largest, but far from the smallest. Duration of one charge = 48 hours. At the same time, this phone charges very quickly.
The only drawback that you can blame the data Sony models- this is a high price, although many call it acceptable, given all the advantages.
Features of HTC One (M9)
HTC is a very young, internationally renowned corporation founded by Cher Wang, HT Cho and Peter Chou in 1997 in Taiwan and quickly found its place in the electronics industry. In 1998 they invented the first touch screen, in 2006 the organization released HTC MTeoR - the world's first 3G smartphone, and by 2015-2016 a new flagship of mobile phones - HTC One (M9) was presented.
Solid-looking metal HTC One (M9) has provided its users with a lot of positive emotions. A large display (5.5 inches), a powerful eight-core processor, a capacious 3000 mAh battery, support for a 2 TB micro SD are the main advantages of this series. In addition, the M9 has in its arsenal:
- camera (front - 5 Mp., main - 13 Mp.);
- memory (operational - 3 GB, built-in - 32 GB.);
- operating system - Android 6.0 Marshmallow;
- minimum weight (170 gr.).
It is also worth noting that the phone comes with a unique case and htc headphones.
The disadvantages often include the lack of protection against moisture, NFC and a fingerprint scanner, as well as the size (for a woman's hand, the phone is too large, but this is compensated by an excellent grip on the skin).
Xiaomi Mi5
Xiaomi is one of the youngest companies from of this list, but not the most lagging behind. It was founded in 2010 by eight partners led by Lei Jun (China). At the moment, this "giant" has in its turnover more than five billion dollars and produces only products top class, without wasting "on trifles". So, in 2016, this organization released its new creation - Mi5.
Famous for Xiaomi Mi5:
- 64-bit quad core Qualcomm processor Snapdragon, with a processor frequency of 1.8 GHz;
- graphics accelerator Adreno 530;
- a high-quality 16-megapixel main camera and a 4-megapixel front camera (plus a two-color ice flash is worth noting);
- powerful battery - 300 mAh;
- operating system Android 6.0 Marshmallow with original MIUI 7 interface.
Also Mi5 has 3 gigabytes of RAM and 32 GB. built-in. It has a compass, barometer, accelerometer, and a fingerprint scanner.
By cons this phone can be attributed to a slippery coating (most users note that the device "runs away" from almost any inclined surface), but it fits comfortably in the hand.
Huawei P9
The largest mobile phone company in China is Huawei. Founded 
and the organization in 1987 by Ren Zhengfei, who in addition was a member of the PLA of China. On yes
At present, the company has a turnover of about $ 60 billion. One of Huawei's top inventions is the P9.
The main distinguishing features of this device are:
- metal case;
- dual 12 megapixel Leica camera (this brand is one of the best cameras in the world);
- battery capacity - 3000 mAh;
- more
16.5 million colors; - front camera - 8 megapixels;
- processor frequency - 2.5 MHz;
- Fingerprint's scanner.
It is also worth noting that the P9 is based on special software - Huawei EMUI 4.1, has a unique Huawei Kirin 955 processor, is equipped with 3 GB of RAM and 32 GB of built-in memory. The diagonal of the screen is 5.2 inches.
LG Group is one of the largest South Korean financial and industrial groups (chaebols). The cash turnover of this company is over $ 80 billion. LG was formed through the merger of Lucky and Goldstar. Heart of the giant p 
located in Seoul (Republic of Korea), and the body has spread to 80 countries, with more than 200 representations. One of the newest inventions is mobile phone LG G5 SE.
Characterizing the G5 SE, it is worth noting that this model has a fully metallized case (unlike previous models), which significantly improved the external performance. Also striking are the two main cameras, 16 and 8 megapixels - a wide shooting angle - 135%, The recording takes place with a resolution of 3840x2160 pixels. As for the main characteristics, they are not much different from the top flagships:
- battery - 2800 mAh;
- the presence of a fingerprint scanner;
- display diagonal - 5.3 inches;
- screen resolution - 1440x2560 pixels;
- color gamut - 167 million;
- OP - Android 6.0;
- processor frequency - 1.8 MHz;
- RAM - 3 GB;
- front camera - 8 megapixels;
- fast charging (up to 100% per hour).
Among the minuses, it is worth highlighting the difficulties in finding replaceable modules, as well as their high price. Also, many users complain about the prohibitive cost of the phone, dim screen and weak battery.
OnePlus 3 - "flagship killer"
OnePlus is the youngest company on our list, founded in December 2013 by Pete Lau. The headquarters of this organization is located in Shenzhen, Guangdong province, China. OnePlus is a unique brand that has conquered a huge audience with no more than three years on the market, thereby pushing giants like HTC, Apple and others. The newest creation of the hands of this company is the OnePlus 3 - the "flagship killer".
Why this device is called that is not difficult to understand, it is enough to evaluate all the characteristics. You can start with cameras: the main eye has 16 megapixels and has a stabilization system (eliminating interference from a shaking hand); the front one has 8 megapixels, while it is equipped with special technical 
nology that allows you to automatically photograph a smiling face.
Also worth highlighting is the combination of the Qualcomm Snapdragon 280 chipset and a mind-boggling amount of RAM - 6 GB, after which we can confidently say that this is the most powerful flagship of phones to date. In addition, all other characteristics fully meet the maximum requirements of the modern market:
- processor 4 cores, 2.2 GHz;
- 64 GB ROM;
- display size - 5.5 inches;
- video accelerator Adreno 530;
Among the minuses, one can single out a weak battery - 3000 mAh (for such powerful phone this will not be enough). But it makes up for fast charging- full battery in just an hour.
conclusions
Having analyzed a considerable number of the coolest phones, we can definitely say that the competitors of the iphone 7 are very strong rivals, which will not be easy to defeat in the struggle for the love of the audience. Some are distinguished by their power, others by a super camera, the third by a capacious battery and reliability. That is why it is impossible to say definitely which of the contenders deserves the 1st place. This is due to the subjective preferences of each of us and the insignificant difference between the devices.
In turn, the iPhone itself also has its pros and cons. Its characteristics are not very different from other flagships, somewhere they exceed, and in some cases are even inferior. People will be able to give a final answer only after years of operation.
