The screen size reaches 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. 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 CUBOT J3 is 960 x 480 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 215 ppi.

PROCESSOR CUBOT J3
Processor Type (CPU) MediaTek
Processor Number MT6580
Clock Speed 1.3 GHz Worse than 57 % of phones rated.
Processor Core Qty Quad-core Worse than 57 % of phones rated.
64-bit Architecture Yes Better than 82 % of phones rated.
Graphics System (GPU) ARM Mali-400 MP2

The processor type of the CUBOT J3 is MediaTek. The number of processor cores is 4. 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. CUBOT J3 is provided with processor´s frequency of 1.3 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 processor also includes the graphics accelerator ARM Mali-400 MP2.

MEMORY CUBOT J3
RAM 1 GB Worse than 61 % of phones rated.
Internal Memory Size (Storage Capacity) 16 GB Worse than 53 % of phones rated.
Supported Flash Memory Cards (Expandable Memory) microSDHC, microSDXC - up to 64 GB

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.

In addition, if you need more memory, this model offers the option of inserting a memory card to increase the storage size.

Operating memory significantly affects the performance of the entire phone. CUBOT J3 has an operating memory of 1 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.

Sensor Resolution 8 Megapixel Better than 52 % of phones rated.
Focus Adjustment Automatic
Light Source LED flash
FRONT CAMERA
Number of Front Cameras 1
Sensor Resolution (Front) 5 Megapixel Worse than 55 % of phones rated.
Focus Adjustment Focus free

The rear camera of the CUBOT J3 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 8 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.

Front camera
The front camera of phone CUBOT J3 has one lens. This number of lenses is standard on most smartphones nowadays. The resolution of main lens reaches 5 Megapixel. Again, it should be noted that resolution is not the only factor affecting the quality of the front camera photo.

BATTERY AND CHARGING CUBOT J3
Battery Capacity (Battery Size) 2000 mAh Worse than 52 % of phones rated.
Standby Time 168 hours Worse than 92 % of phones rated.
Run Time Details Standby: up to 168 hrs
Playback (audio): up to 15 hrs
Continuous browsing: up to 10 hrs
Reading (book): up to 13 hrs

The battery size of CUBOT J3 is 2000 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.

Standby time is 168 hours. The value indicates how long your phone will last on a single charge when you are not actively using it.
