iPhones have been among the most anticipated smartphones for years now. The American company Apple makes every effort to maintain the impeccable reputation of its products. Smartphones are among the key ones in its portfolio and therefore we see a lot of innovation in their face.

Before reading the full review, you can familiarize yourself with the detailed Apple iPhone 6s specs or watch the video below the article.

The appearance of the iPhone 6s, like its predecessors, was also long awaited. A lot of rumours have been swirling online.  Compared to the iPhone 6 model, the features of the new device look impressive indeed. The RAM has been increased, the CPU frequency has been increased, the camera has been significantly improved. At the same time, the battery capacity has been reduced and the weight and thickness are slightly larger.

Let's take a closer look at the iPhone 6s - this is a model that will be relevant on the market for at least a few years.

The appearance of the iPhone 6s has remained virtually unchanged. It makes sense that Apple would choose this path, as consumers have the ability to get attached to the shape and design of their phones. The front surface of the iPhone 6s is no different from that of the iPhone 6. The layout of all the controls and ports is completely identical. In other words, if you replace your device with the new iPhone, there will be no need for an adaptation period.

You can tell the old model from the new one by the fact that the back surface is emblazoned with the letter S. There's one more difference that's easy to spot. Take the two smartphones in hand. The iPhone 6s is slightly heavier - by 15 grams. In addition, this iPhone is also thicker. As it will turn out later, this is not a reason for weaker performance.

According to the manufacturer, the iPhone 6s uses a new type of aluminum that is used in the aerospace industry, and even stronger glass.

Something new in this Apple model is the additional color. Rose gold. If we recall the history of the company's smartphones, it has always been noticeable that the S-indexed iPhone gets some new body color. Rose gold definitely looks more girly and is a guarantee that it will reap success among the ladies.


As with the previous iPhone, we see two levels of protection on the iPhone 6s. The user has a Touch ID fingerprint scanner and a PIN. Both systems have undergone changes. The fingerprint sensor now works faster. With the PIN, we see that it now consists of six characters instead of four. This change is a double-edged sword. On the one hand, Apple is trying to encourage users to use TouchID more actively, on the other - now the PIN is now 6 characters, which makes it harder to "crack". For those of you who struggle to remember such long passwords, you can revert to the four-character password in the settings.


iPhone 6s runs on Apple's A9 SoC, built on 14nm technology. The manufacturer of the SoC is the South Korean company Samsung. Apple usually does not report almost any technical details, only saying that the current solution is faster than the one used so far.

According to reports from various sources, it is a single-chip system that includes a 2-core 64-bit CPU with an ARMv8-A-based architecture, a six-core PowerVR 7XT series GPU, and an Apple M9 co-processor that is now integrated into the SoC itself. This way, the co-processor runs more power-efficiently and is always available for Siri.

The smartphone goes with 2 GB of RAM and 16/64/128 GB of internal storage.

What performance does the iPhone 6s demonstrate? Flagship-level. It's ample enough to play whatever games you want.

3D Touch

The main innovation in the iPhone 6s screen is the 3D Touch technology. It determines the degree of pressure on the screen. The technology is implemented through special sensors that are embedded in the backlight layer of the display. They determine the pressure variations. Pressing the display when 3D Touch is triggered is accompanied by a short vibration that confirms the action.

Thanks to 3D Touch, the user can access certain functions and programs directly from the main screen.


The main camera in the iPhone 6s, as before, consists of 5 lenses, but this time the company from Cupertino has used a 12-megapixel sensor with an aperture of ƒ/2.2, a hybrid infrared filter and phase autofocus.

Despite the increase in camera resolution on the iPhone 6s, you won't notice a significant increase in photo quality compared to its predecessor. At the same time, the detail is higher. The camera demonstrates more natural colours. In automatic mode, you will enjoy satisfying photos.

The front camera of iPhone 6s is a 5-megapixel one. The higher resolution has positively affected the detail of the photos.

In Apple originally solved the issue with the flash for the front camera. In fact, it is absent on its own. Its task is partially handled by the display, which lights up more strongly during shooting.

Fans of shooting video with a phone will properly appreciate the ability of the iPhone 6s to shoot video in 4K format. This resolution is adjustable from the camera menu.

Live Photo

Consumers love novelty, and Apple tries to respond to that. One of the innovations in the iPhone 6s camera is the creation of animated photographs. These are similar to GIFs, but of higher quality.

Autonomous operation

The battery capacity of the cute iPhone 6s amounts to 1715 mAh. If you recall the iPhone 6 had a 95 mAh bigger battery. This fact may surprise you as the newer iPhone has a higher weight and is a bit thicker than its predecessor. The good news is that despite the smaller battery capacity, the iPhone 6s's battery life is impressive. It outperforms all previous iPhones.


The iPhone 6s is a device that doesn't offer a new design, but it's armed with a bunch of innovations that no Apple fan won't appreciate. The smartphone has become noticeably faster, more rugged and has received an improved camera. The fingerprint scanner works faster, which only benefits the user - interacting with the iPhone is even more comfortable. We should also mention the 3D Touch technology! It greatly speeds up navigation on the iOS9 interface and apps.
