Samsung Galaxy Z Fold3 5G 512 GB Specifications, Tests and Review

Design of Samsung Galaxy Z Fold3 5G 512 GB has dimensions of 158.2 mm × 67.1 mm × 16 mm and weight of 271 g. The water resistance of the phone´s design is also worth mentioning.

The screen size reaches 7.6" inches. With a large display, phone offers a great experience for watching videos, playing games and reading. The best phones today are 6.5'' or more. They have the advantage of a large display area that allows you to see more content than with conventional display sizes. Owing to OLED technology, the display offers a true representation of colours, especially black. The resulting contrast is significantly higher and colours appear more vivid. OLED technology is now part of most smartphones, while LCD displays are becoming a thing of the past in mobile phones. OLED displays also have lower power consumption compared to LCD technology.

Display Resolution of Samsung Galaxy Z Fold3 5G 512 GB is 2208 x 1768 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 374 ppi.

The refresh rate is 120 Hz. This value indicates how many times per second display shows new information. Previously, 60 Hz was considered the standard, but today the average frequency for mid-range phones is more like 90 Hz. Modern phones now reach frequencies of around 120 Hz and above. Higher frequencies mean a better user experience when browsing the internet and especially when playing games.

The processor type of the Samsung Galaxy Z Fold3 5G 512 GB is Qualcomm Snapdragon 888 5G. The number of processor cores is 8. It is a number of cores that plays an important role in evaluating the performance of phone as it is responsible for computing operations. Smartphones already commonly have a core count of around 4 to 8. Multi-core processors can perform better and reduce the processing time of a request to a minimum, which is reflected in the responsiveness of the phone, e.g. in the speed of opening applications. Samsung Galaxy Z Fold3 5G 512 GB is provided with processor´s frequency of 2.84 GHz. Normally today you will find this value between 1.8 and 2.8 GHz, and the higher the number, the faster the response of the phone. The processor frequency will thus be one of the important parameters if you are looking for a phone capable of managing several requests at once without major problems.

The phone is provided with an internal memory of 512 GB. Internal storage capacity is often a key parameter, as it determines how many files, photos, apps and more your phone can store. Best phones like this one have 256 GB to 1 TB of memory, which is already enough for even the most demanding geeks who use the phone to create videos, take high-resolution photos and play more demanding games. The downside is that with most phones, you'll have to pay extra for that kind of storage capacity. Fortunately, manufacturers nowadays think of all users and therefore offer phone models with different memory sizes so that everyone can choose what suits them.

Operating memory significantly affects the performance of the entire phone. Samsung Galaxy Z Fold3 5G 512 GB has an operating memory of 12 GB. Phones with less than 4 GB of RAM are better suited for undemanding users who use phone more for basic needs and some essential applications only. But if you are a heavy user, reach for at least 6 to 8 GB of RAM, which is the standard today, or 12 GB for the really demanding ones.

The rear camera of the Samsung Galaxy Z Fold3 5G 512 GB is equipped with 3 lenses. A larger number of lenses usually results in better quality photo, as each lens is designed differently: usually as a macro lens, telephoto lens or wide-angle lens. Macro lens is used for great close-ups, telephoto lens is designed for capturing objects in the distance as it often has an optical zoom, and wide-angle lens will take great landscape photos where you need a larger field of view. The main lens is designed as Ultra wide-angle lens. A high resolution lens alone does not necessarily mean high quality photos. The main lens in this has a resolution of 12 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. Pixel size is 1.12 μm. Average value is typically around 0.8 μm to 1.8 μm on better mobile phones, and again, the higher the number, the higher the photo quality. Luminance is one of the main factors determining the quality of a photograph. Commonly today, this value ranges between F/1.8 and F/2.2. However, best photomobiles have an aperture of up to F/1.2. Value indicates how much light passes through the sensor and the lower it is, the better the quality of the photos. Main lens here is equipped with F/2.2.

Digital zoom in this case offers zooming up to 10x. 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. You should also pay attention to optical zoom, as it is far more important than the digital zoom. Its main advantage is that image does not lose quality or sharpness as you zoom in. Optical zoom in this case is 2x. 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. If you like to take photos of people and portraits, you'll appreciate the facial recognition feature. The camera automatically detects face and focuses on it.

Second camera
The second lens of rear camera is designed as Wide-angle lens. The field of view of second lens reaches 83 degree(s). The resolution reaches size of 12 Megapixel. Pixel size in this case is 1.8 μm. Furthermore, aperture of second lens reaches size of F/1.8.

Third camera
The third lens is designed as Telephoto lens. The field of view reaches 45 degree(s). The resolution of third lens is then 12 Megapixel. The pixel size that significantly affects quality of photo is 1 μm. Finally, the lens also features a lens aperture of F/2.4.

Front camera
The front camera of Samsung Galaxy Z Fold3 5G 512 GB is equipped with 2 lenses, with each lens having a different function when taking pictures. The resolution of main lens reaches 10 Megapixel. Again, it should be noted that resolution is not the only factor affecting the quality of the front camera photo. The pixel size itself is 1.22 μm. The aperture of main lens is F/2.2. The field of view of front camera is 80 degree(s).

Second front camera
You won't see a second front lens on most smartphones yet. Having more than one front lens in Samsung Galaxy Z Fold3 5G 512 GB is thus rather exceptional in world of phones. The resolution of second front lens reaches 4 Megapixel. The lens aperture is designed to F/1.8.

The battery size of Samsung Galaxy Z Fold3 5G 512 GB is 4400 mAh. Nevertheless, battery capacity is not the only factor that affects the phone's battery life. For example - the size of the display, the performance of the processor, the use of data functions and, of course, the intensity of use of phone in general all have a significant impact on battery life. Standard for most smartphones today is a battery capacity of around 4500 to 5000 mAH. Phones with this battery size usually guarantee a phone life of at least 1 day. Older or cheaper smartphone models can then reach battery capacities typically around 2500 mAH and below. With this capacity, you may find that if you use your phone heavily, you may need to recharge your phone during the day. 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 Samsung Galaxy Z Fold3 5G 512 GB it is 2040 minutes. Many users will also welcome the wireless charging feature. Wireless charging keeps your phone from overheating and also protects the connector from wear and tear. On the other hand, it does cause some power loss. You'll also enjoy the fast charging function, which allows for faster power flow and thus up to several times faster charging of the phone.

Samsung Galaxy Z Fold3 5G 512 GB supports 5G. 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 Android 10. Among other benefits It also includes payment technology Samsung Pay.

The NFC function will please all fans of contactless mobile payments. In addition, you can also use function in the context of connectivity, for example, to unlock doors or load menus in restaurants. Bluetooth 5.2 makes it easy to connect your phone to other wireless devices such as headphones, speakers, TV or tablet and more. Samsung Galaxy Z Fold3 5G 512 GB is also equipped with UWB technology, a wireless communication technology that enables even faster transfer of larger amounts of data between devices. At the same time, it provides even better localization of mobile device, for example, if it is lost. UWB is said to be the emerging wireless technology of future, which should soon replace use of Bluetooth or NFC.
