Mobile network functionality is an important feature that must be available on modern devices. This feature enables users to use a SIM card to access online networks, facilitating connections between individuals. Good mobile networks must have a fast connection, use the latest technology, and adopt extra features to support the needs of users.

In our matrix calculation, we calculate the mobile network score using a technology adoption approach. If a device offers more complete features on the network bands and uses extra features on the SIM card function, it will receive a higher score. A higher score on this segment will provide a faster and more flexible experience when using the mobile network function.

Similar to the mobile network function, the connectivity feature is also an important feature for modern devices. With this feature, devices can connect to other supporting gadgets, such as internet routers, computers, speakers, wearable devices, and others.

Good connectivity features on devices must adopt all the latest wireless connection technologies available. This ability allows devices to make more connections to other devices using the latest Bluetooth technology with lower latency and achieve faster internet connection from the WLAN network.

In this situation, we use a calculation methodology with a technology approach. If a device supports more features on the WLAN function, uses the latest Bluetooth version, and has a modern universal connection port, we can assign a high score to the device. This means that a higher score will bring a more flexible user experience in terms of connectivity.

The body material is an important consideration for users who want a premium device or need the device for long term use. Therefore, the device must have a good and strong body material component.

In this segmentation, we measure the body and design score using a quality and variety color approach. If a device uses good materials like aluminum and stainless steel, the score will be higher than a device that adopts plastic as the main body material component. If a device uses a more premium body material component and also provides extra protection from water and dust damage, the score will be even higher.

However, we do not include body dimensions and weight information in our matrix calculation because these factors are subjective and can vary from user to user. Some users may prefer larger and bolder devices, while others may prefer smaller and lighter ones. Therefore, we do not include this information in the score calculation.

The chipset performance on a device is a vital aspect that concerns most people. This is reasonable because most users want a device that can process tasks quickly. The CPU and GPU are the main components that affect performance.

The CPU processes tasks, and the GPU renders images. Both are related to providing the best experience for users. The better the CPU, the more efficient the device will be in terms of battery consumption, because the best CPU is smarter and more advanced in handling system logic.

We calculate the matrix for this segmentation using a performance result approach, where the data is obtained from several benchmark tools. This is done to bring more relevance to the actual data from the performance score. Additionally, the latest chipset model is not always better than the older chipset model because we use an overall performance approach that calculates based on real performance and not just based on the chipset model.

The total score is calculated from the combination of the CPU and GPU scores. The higher the score, the faster and smoother the processing will be for the user's needs.

Besides the chipset, memory is also an important component that users must consider when purchasing a device, as it is closely related to the device's performance.

For instance, multitasking is a simple example that highlights the importance of memory performance. If the RAM storage is insufficient, the user may not be able to run several apps simultaneously, and if the RAM runs out, the apps may crash, which can cause the device to reboot automatically.

Moreover, modern apps require large RAM usage to run smoothly, making the RAM sector a crucial factor in our matrix calculation score. We can say that 65% of the score comes from the RAM performance.

We also consider the internal storage when calculating our score. A larger internal storage size will result in a higher score, as the internal storage is crucial for multimedia purposes, among others. Therefore, we pay more attention to this sector.

However, we do not include external storage in our matrix score calculation because several modern users prefer to use cloud storage services instead of physical expansion memory. Furthermore, cloud storage services offer many benefits such as ease of use, safety, and lower cost, as opposed to buying external memory expansion, which is more expensive and less safe.

A good device is one that can last all day. Modern devices can typically endure for more than 20 hours under normal use, although some may only last for 16 to 18 hours. Therefore, if you want a device with a good battery life, you should pay attention to the battery segmentation on the device.

To help users determine how good the battery sector is on a device, we calculate a score using several metrics. First, we calculate the battery capacity and also consider battery features such as whether it supports fast charging or not.

We also factor in the charger method support to create a score. If the device supports multiple charge methods, such as wireless charging, we give it a higher score in the battery segmentation. However, we do not include battery type information in our matrix calculation because it is unnecessary.

It's important to note that a higher score on the battery segmentation does not necessarily mean that the device will have better battery endurance life than other devices. Although it is usually the case, our score is not based solely on battery life but also on the advanced battery features and support available on the device.

The camera feature is a brilliant thing that modern devices offer. With this feature, we can capture any moment as quickly as possible and share the result directly on social media to show others the interesting moments we capture.

Generally, modern devices come equipped with a single camera, while others have more than one camera setup. This is amazing because with a variety of camera lens styles on a single device, we can take photos in multiple styles, including portrait photos, landscape photos, or take photos of faraway objects using zoom cameras.

A good camera feature should produce high quality, clear images with low noise and offer multiple lens styles. You can determine the quality of the camera feature by looking at the score on the camera segmentation. If the score is high, that means the camera feature on that device is brilliant and very good.

For the matrix calculation, we not only consider individual camera specifications but also combine all information data. We consider how many camera lenses are available on the device, how good the main camera features are for both rear and front cameras, and how good the camera can be used for recording video. All of these factors directly impact the matrix calculation score.
