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 Fold4 is 2176 x 1812 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. Display´s pixel density is 374 ppi and represents another significant factor affecting image sharpness besides resolution. The higher the value, the sharper the image. Average value is currently about 350-400 ppi, which guarantees a fine and sufficiently sharp image. Finest modern phone displays reach 450 ppi and above.
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 rear camera of the Samsung Galaxy Z Fold4 is equipped with 3 lenses, with each lens having a different role in taking pictures. Most common lens you'll see on smartphones is a wide-angle lens, telephoto lens or macro lens. A wide-angle lens is mainly used to capture landscapes and other spatially larger compositions where a wide field of view is needed. A telephoto lens is designed for photographing subjects at a distance and often has an optical zoom. A macro lens is ideal for close-ups and small objects. The main lens is designed as Wide-angle lens. The resolution of the main lens is 50 Megapixel. Higher resolution does not necessarily mean super high quality photos. Furthermore, it depends on the pixel size but also on other important factors. Pixel size is 1 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. The aperture of main lens reaches F/1.8 value. The best phones have a lens with an aperture of up to F/1.5, where more light can pass through sensor and photos will be of a high quality even in low light conditions. However, lenses with apertures around F/1.8 to F/2.2 are the most common. The lower the number after the slash, the better the photo quality.
Digital zoom in this case offers zooming up to 12x. 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 3x. 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. Some users will also appreciate facial recognition feature, which allows camera to recognise the face of person in frame and automatically focus on it.
Second camera
The second lens of rear camera is designed as Ultra wide-angle lens. The field of view of second lens reaches 123 degree(s). The resolution reaches size of 12 Megapixel. Pixel size in this case is 1.12 μm. Furthermore, the second lens is equipped with aperture of F/2.2.
Third camera
The third lens is designed as Telephoto lens. The field of view reaches 36 degree(s). The resolution of third lens is then 10 Megapixel. The pixel size that significantly affects quality of photo is 1 μm. Last but not least, third lens is equipped with a lens aperture of F/2.4.
Front camera
The front camera of Samsung Galaxy Z Fold4 is equipped with 2 lenses, with each lens having a different function when taking pictures. The resolution of front lens reaches 10 Megapixel. Again, it should be noted that resolution is only one of several other significant factors that affect resulting quality of a photo. The pixel size itself is 1.22 μm. The main lens is also equipped with aperture of F/2.2. The field of view of front camera is 85 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 Fold4 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 Fold4 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. Talk time, or we can say battery life when making calls, then indicates amount of time your phone will last from a full charge if you are constantly on a call. Samsung Galaxy Z Fold4 is provided with a talk time about 2340 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.
