ASUS ROG Phone 3 Specifications, Tests and Review

The ASUS ROG Phone 3 has dimensions 171 mm × 78 mm × 9.85 mm. Its weight is 240 g.

The screen size reaches 6.59" 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 ASUS ROG Phone 3 is 2340 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.

The refresh rate is 144 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.

ASUS ROG Phone 3 is supplied with Qualcomm Snapdragon 865. 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. Another important parameter is the processor frequency, which indicates how many instructions the phone can process in one second. Similar to refresh rate, the higher the number, the faster the phone responds. Processor frequency of phone ASUS ROG Phone 3 is 2.84 GHz. As standard today, you'll find this value between 1.8 GHz and 2.8 GHz.

The processor also includes the graphics accelerator Qualcomm ADRENO 650.

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 256 GB storage. 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. 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.

Size of the RAM memory tells us how powerful the phone is. ASUS ROG Phone 3 is equipped with LPDDR4X SDRAM - 8 GB. 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 phone ASUS ROG Phone 3 has 2 lenses. Today's modern phones usually have several rear lenses. The most common are macro lens, telephoto lens and wide-angle lens. Each is used to capture the perfect photo - macro lens is designed for close-up photography, telephoto lens, often equipped with an optical zoom, is for photos of objects in distance, and wide-angle lens captures larger areas where you need a wider field of view. The resolution of main lens is 64 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.

Second camera
The resolution reaches size of 13 Megapixel.

Front camera
The front camera of phone ASUS ROG Phone 3 has one lens. This number of lenses is standard on most smartphones nowadays. The lens is equipped with 24 Megapixel. However, do not forget there are other factors than resolution having impact on the final quality of front camera photos.

The battery size of ASUS ROG Phone 3 is 6000 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.

Standard 4G connectivity is currently being replaced by 5G, but is still the preserve of the latest phones. ASUS ROG Phone 3 supports 5G. 3G connectivity is now only found in the oldest phones. The operating system in the case of this model is Android 10.

Contactless payments are not a problem with this phone, thanks to NFC function. It can also be used, for example, to unlock doors or load menus in a restaurant using an NFC tag. Bluetooth 5.1 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.
