verykool i316 Opal Specifications, Tests and Review

Design of verykool i316 Opal has dimensions of 89 mm × 44 mm × 12 mm and weight of 69 g.

The screen size reaches 1.77" 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 verykool i316 Opal is 128 x 160 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.

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

The rear camera of the verykool i316 Opal 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 0.3 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.

The battery size of verykool i316 Opal is 800 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 verykool i316 Opal it is 240 minutes.

Bluetooth 3.0 makes it easy to connect your phone to other wireless devices such as headphones, speakers, TV or tablet and more.
