STK R45i Specifications, Tests and Review

The STK R45i has dimensions 113 mm × 46 mm × 12.8 mm. Its weight is 59.2 g.

The screen size reaches 1.77" inches. Phones with smaller displays have the advantage of being easier to use with one hand. However, compared to phones with large screens, they provide a lower user experience. Nevertheless, if you don't plan to watch movies or play games on your phone regularly and just expect basic functionality, this size should be good enough for you. 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 STK R45i 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.

STK R45i is supplied with Spreadtrum 6531DA.

One of the most important parameters for user´s decision is often internal memory capacity. The larger it is, the more apps, photos, movies and other files your phone can store. This phone has 32 MB storage. 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. Nowadays, you can usually find one phone model on the market with several different memory sizes. This allows each user to choose what suits them best.

For this model it is possible to increase the storage size by inserting a memory card.

Size of the RAM memory tells us how powerful the phone is. STK R45i is equipped with 32 MB. Commonly today you will find phones with 6 to 8 GB of RAM. This means that the phone can easily handle normal operation and more demanding applications or games. Higher RAM of 12 GB can be found in best phones on market and are ideal especially for avid gamers. On the other hand, operating memory below 4 GB is more of an issue with lower-end phones and older models. However, even they will find their fans among less demanding users, who don´t want to spend much on buying new phone.

The rear camera of the STK R45i 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. The resolution of main lens is 0.3 Megapixel. Nonetheless, resolution alone does not necessarily mean a good photo. Therefore, you should look at other parameters such as lens aperture or pixel size.

The battery size of STK R45i is 600 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 standby time for this phone is 120 hours and tells us how long the phone lasts on a single charge when you're not actively using it. The phone STK R45i will last one charge with constant phone calls 120 minutes.

Bluetooth 2.1 EDR must not be missing from the basic package. It makes it easy to connect wireless headphones to your phone, connect your phone to your TV, tablet, speaker and more.
