The screen size reaches 6.67" 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. 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 TCL 20 5G is 2400 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. Display´s pixel density is 395 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.

PROCESSOR TCL 20 5G
Processor Type (CPU) Qualcomm Snapdragon 690 5G
Clock Speed 2 GHz Better than 70 % of phones rated.
Processor Core Qty 8-core Better than 99 % of phones rated.
Graphics System (GPU) Qualcomm ADRENO 619L

TCL 20 5G is equipped with Qualcomm Snapdragon 690 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. The processor frequency indicates how many instructions phone can process in 1 second. The higher the frequency, the better the performance. Standard processor frequency range today is between 1.8 GHz and 2.8 GHz. TCL 20 5G reaches the frequency of 2 GHz.

The processor also includes the graphics accelerator Qualcomm ADRENO 619L.

MEMORY TCL 20 5G
RAM LPDDR4X SDRAM - 6 GB Better than 89 % of phones rated.
Internal Memory Size (Storage Capacity) 256 GB Better than 98 % of phones rated.
Memory Interface UFS 2.1
Supported Flash Memory Cards (Expandable Memory) microSDHC, microSD, microSDXC - up to 256 GB

The phone´s internal memory capacity is 256 GB. The size of the internal storage determines e.g., how many photos, songs, movies, or applications you can store on your phone. 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. Luckily, most smartphone manufacturers nowadays offer models with different memory sizes to suit every user.

An additional option to increase the storage capacity of this model is to insert a memory card.

RAM memory of the TCL 20 5G is LPDDR4X SDRAM - 6 GB. Most powerful phones currently have an operating memory of 12 GB or more, which is especially useful for demanding users such as gaming enthusiasts. Normally, phones nowadays have 6 to 8 GB of RAM, which means that the phone can easily handle normal operation and more demanding applications. Operating memory of less than 4 GB is found in lower-end phones or older models, and they are suitable for low-end users who don't use demanding applications and have the phone more for basic use.

The rear camera of the TCL 20 5G 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 resolution of the main lens is 48 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 typically around 0.8-1.8 μm in better mobile phones. The higher the value, the better the quality of the resulting photo should be. In the case of main lens, the pixel size reaches 0.8 μm.

The size of the phone's sensor is also among the parameters that affect quality of the photo. In case of TCL 20 5G, it is 1/2". Focus mainly on the value after the slash, where the higher it is, the better photo quality will be. 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 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.

Second camera
The second lens of rear camera is designed as Super wide-angle lens. The field of view of second lens reaches 118 degree(s). The resolution reaches size of 8 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 lens achieves a field of view of up to 83 degree(s). The resolution of third lens is then 2 Megapixel. The pixel size that significantly affects quality of photo is 1.75 μm. Last but not least, third lens is equipped with a lens aperture of F/2.4.

Front camera
The front camera of phone TCL 20 5G has one lens. This number of lenses is standard on most smartphones nowadays. The resolution of front lens reaches 8 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 1.12 μm. The main lens is also equipped with aperture of F/2.0. As for the field of view of main lens of front camera, it reaches 78 degree(s).

BATTERY AND CHARGING TCL 20 5G
Battery Capacity (Battery Size) 4500 mAh Better than 91 % of phones rated.
Fast Charging Technology Qualcomm Quick Charge 4.0+ Better than 86 % of phones rated.
Recharge Time (Charging Time) 2.5 hour(s) Better than 51 % of phones rated.

The battery size of TCL 20 5G is 4500 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 fast charging function will also please many people. Owing to fast charging, phone charges up to several times faster, which you will appreciate, for example, on the go.
