Apple iPhone 4 16 GB Specifications, Tests and Review

Design of Apple iPhone 4 16 GB has dimensions of 115 mm × 59 mm × 9 mm and weight of 137 g.

The screen size reaches 3.5" inches. Smaller phone displays are not necessarily a disadvantage. They are easier to use with one hand. However, displays of these sizes don't provide the same experience when watching videos or playing games, so they're better suited for less demanding users. It means, if you're a basic user and you don't expect to use your phone for activities like watching videos or playing games on regular basis, this size is perfectly adequate. LCD displays are currently taking a back seat. This is mainly due to higher power consumption. In addition, they have the disadvantage of lower colour contrast, which can be reflected e.g. in the resulting photos. On the other hand, phones with LCD displays are in general cheaper than those with OLED technology.

Display Resolution of Apple iPhone 4 16 GB is 960 x 640 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. If you want a perfect picture, focus on pixel density in addition to resolution. This number indicates how sharp the image will be. Best phones today have a display fineness of 450 ppi or higher, but the today´s average is around 350-400 ppi. That should be enough for you to enjoy a fine and sharp image. This model has a pixel density of 326 ppi.

The processor type of the Apple iPhone 4 16 GB is Apple A4.

The phone is provided with an internal memory of 16 GB. Internal storage capacity is often a key parameter, as it determines how many files, photos, apps and more your phone can store. 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. Fortunately, manufacturers nowadays think of all users and therefore offer phone models with different memory sizes so that everyone can choose what suits them.

The rear camera of the Apple iPhone 4 16 GB 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. A high resolution lens alone does not necessarily mean high quality photos. The main lens in this has a resolution of 5 Megapixel. However, if you are looking for perfect photos, in addition to resolution, don't forget to focus on at other parameters such as lens aperture or pixel size.

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.

Standby time is 300 hours. The value indicates how long your phone will last on a single charge when you are not actively using it. The battery life when making calls is, like standby time, a figure that tells us how long the phone will last on a single charge when making continuous calls. For the Apple iPhone 4 16 GB it is 840 minutes.

Apple iPhone 4 16 GB supports 3G. 4G connectivity is still common today, although the latest phones already have 5G connectivity. 3G connectivity is now more of a thing of past and can only be found on older models. The phone's operating system is iOS 4.

Bluetooth 2.1 EDR makes it easy to connect your phone to other wireless devices such as headphones, speakers, TV or tablet and more.
