They have the advantage of a large display area that allows you to see more content than with conventional display sizes. The disadvantage of LCD displays is the relatively lower color contrast displayed, as the technology cannot display absolute black well. Also due to the higher power consumption, LCD displays are no longer as common in phones. Even so, some manufacturers still equip their phones with LCD technology. However, modern smartphones are already using OLED technology. The advantage of LCD phones is that they tend to be cheaper to build than OLED technology.

Display Resolution of Apple iPhone 6s Plus (Apple A9 - with M9) is 1920 x 1080 pixels. A higher display resolution is a prerequisite for a sharper image. The standard for mid-range phones today is a Full HD resolution of 1920 × 1080 px. Cheaper phones, which usually have a smaller diagonal, have an HD resolution of 1280 × 720 px. Smaller resolutions can only be found in older models. Best phones, on the other hand, have a 4K resolution of 3840 x 2160 px. Another important factor having impact on the final image is display´s pixel density. In case of this model, the value reaches 401 ppi. With pixel density, the higher the value, the sharper the image will be. On average today, the image fineness value is around 350-400 ppi. This will guarantee a sufficiently fine and sharp image for normal use. However, the best phones on the market today are equipped with pixel density of 450 ppi or higher.

Apple iPhone 6s Plus (Apple A9 - with M9) is supplied with Apple A9 - with M9.

One of the most important parameters for user´s decision is often internal memory capacity. The larger it is, the more apps, photos, movies and other files your phone can store. This phone has 16 GB storage. This memory capacity is ideal for those who have a few basic apps and a few dozen photos on their phone. If you don't expect to use your phone to play games or need to store high-resolution photos, this size should be sufficient. There is almost no probability you're likely to see this low capacity on new smartphones. The standard memory today is around 64 and 128 GB. The best phones have internal memory of 256 GB or more. Nowadays, you can usually find one phone model on the market with several different memory sizes. This allows each user to choose what suits them best.

The rear camera of the Apple iPhone 6s Plus (Apple A9 - with M9) has only one lens. Single lens is more typical for older phones or lower-end phones with lower quality cameras. The rear cameras of modern phones nowadays are usually equipped with two, three and sometimes even five rear camera lenses. The resolution of main lens is 12 Megapixel. Nonetheless, resolution alone does not necessarily mean a good photo. Therefore, you should look at other parameters such as lens aperture or pixel size. Another important factor is the aperture, which in this case is F/2.2 and determines how much light passes through the sensor. Best phones have an aperture of up to F/1.5. But the most common lenses today are F/1.8 to F/2.2. In this case, the lower the number after the slash, the higher the photo quality.

Digital zoom in this case offers zooming up to 5x. Of course, the higher the lens value, the more distant object can be zoomed in. Nonetheless, the disadvantage of digital zoom is that the quality and sharpness of photo deteriorates when using it. An undeniable advantage is the optical image stabilisation, which makes image significantly more stable without any loss in quality. Cheaper phone models are equipped with electronic stabilisation, which has a negative effect on the resulting image quality. Many people will also benefit from the facial recognition feature. In translation it means the camera can recognise face of person in the frame and automatically focus on it.

A nice bonus here is the facial recognition function.
