| Weight | 75 g (2.65 oz) |
| SIM | Dual SIM, (Mini-SIM, dual stand-by) |
Dimensions
The smartphone’s dimensions are 112.7 x 46.4 x 13.1 mm, which translates to 4.44 x 1.83 x 0.52 inches. This makes the phone compact and easy to hold or slip into a pocket.
Weight
This phone is lightweight and weighs only 75 grams (2.65 ounces). This light weight makes it comfortable to carry around all day without feeling bulky or heavy.
SIM
The phone supports dual SIM functionality, utilizing Mini-SIM cards and allowing dual standby. This means you can manage two different phone numbers on a single device, which is convenient for separating work and personal calls.
Display
| Type | TFT, 65K colors |
| Size | 2.0 inches, 12.6 cm2 (~24.1% screen-to-body ratio) |
| Resolution | 128 x 160 pixels (~102 ppi density) |
Type
The display is a TFT screen capable of showing 65K colours. TFT, or Thin Film Transistor technology, ensures good image quality and brightness, though it might not match the vibrancy of more advanced display types like AMOLED.
Size
The screen measures 2.0 inches diagonally, covering an area of 12.6 cm². This relatively small screen size results in a compact device that’s easy to navigate with one hand, though it may not be ideal for media consumption.
Resolution
The display’s resolution is 128 x 160 pixels, equating to approximately 102 pixels per inch (ppi). While this is not high by modern standards, it provides essential clarity for tasks like texting and calling. The screen resolution and density are suitable for a device of this size, offering readable text and simple graphics.
Camera Capabilities of Samsung SM-B310E
Unfortunately, the user of Guru Music 2 has to use this phone without a camera as there is no camera available on this mobile phone.
Software and User Interface
A phone with a phone’s 208 MHz CPU (Central Processing Unit) indicates the speed at which the processor operates. The CPU is the phone’s brain, handling instructions from software and performing calculations.
A 208 MHz CPU is relatively slow compared to modern standards, where smartphone CPUs typically operate in several gigahertz (GHz) range. This lower clock speed suggests that the phone is likely a feature rather than a smartphone.
Reasons for Not Having Other Smartphone Features
- Simple OS: Feature phones typically run lightweight operating systems designed for basic tasks such as calling, texting, and simple apps (like a calculator or calendar). These systems do not require the advanced processing capabilities of a faster CPU.
- App Limitations: The limited CPU power means the phone cannot support a wide range of apps and services that are standard on smartphones. For example, high-performance apps like social media, navigation, and multimedia apps require more robust processing capabilities.
- Affordability: This makes them attractive in markets where cost is critical.
- Target Audience: Feature phones target users who need basic functionality at a low cost, such as those in developing regions, older people, or as secondary devices. These users do not require the advanced features of smartphones.
- Limited Multimedia Capabilities: The CPU’s limited power means that high-resolution cameras, HD video recording, and advanced audio processing are not feasible. Feature phones usually have primary cameras and minimal multimedia features.
Battery Performance and Charging
| Type | Li-Ion 800 mAh, removable |
| Talk time | Up to 11 h (3G) |
The battery specified here is a Lithium-Ion (Li-Ion) type with a capacity of 800 milliampere-hours (mAh) and is removable.
The capacity of 800 mAh indicates the amount of charge the battery can hold, which is relatively small compared to modern smartphone batteries that typically range from 3000 mAh to 5000 mAh or more. The talk time of up to 11 hours on a 3G network suggests that the device is efficient in its power usage.
The Li-Ion 800 mAh removable battery is designed to provide sufficient power for an essential feature phone with low power consumption. Its capacity, while small by modern standards, is adequate due to the phone’s efficient use of power.
The removable nature of the battery adds convenience and extends the device’s lifespan. The phone does not include advanced smartphone features because it is tailored to different priorities: affordability, long battery life, simplicity, and durability, rather than high performance and advanced functionality.
