Overview of Celkon A518
The Celkon A518, launched in April 2015, is a budget smartphone that has been discontinued. This smartphone aimed to provide essential features within a reasonable price range. Below is a comprehensive analysis of its specifications and performance across various domains.
Design and Build
The Celkon A518 features dimensions of 145 x 73 x 9.8 mm, making it a moderately sized phone that fits comfortably in hand. Weighing 164 grams, it is relatively lightweight, ensuring ease of portability. The dual SIM capability supports two GSM SIM cards, catering to users who need different numbers for personal and professional use. It was available in two classic color options: Blue and White, appealing to a wide audience.
Display
The device is equipped with a 5.0-inch TFT display, supporting up to 256K colors which is typical for budget phones. It offers a resolution of 480 x 854 pixels, translating to a pixel density of approximately 196 ppi. This ensures basic clarity for everyday activities such as browsing and messaging, though the display might not cater well to users looking for high-definition video streaming experiences.
Hardware Performance
At the core of the Celkon A518 is the Spreadtrum 7715 chipset, powered by a 1.0 GHz processor and Mali-400 GPU. This setup provides adequate performance for basic tasks but is limited when it comes to gaming or multitasking heavy applications. The internal memory is constrained to 4GB, paired with 512MB of RAM, which is minimal by today’s standards, allowing only fundamental apps and operations without additional storage.
Memory and Storage
The phone's internal storage of 4GB can be expanded via a microSDHC card, though it's essential for users to manage installed applications and stored media carefully. The 512MB RAM restricts the phone's capability to run numerous applications simultaneously without experiencing slowdowns.
Camera
In the camera department, the Celkon A518 offers a modest 3.15 MP main camera featuring an LED flash, useful for low-light conditions. It supports basic video recording functions, suitable for casual photography. Additionally, the front-facing camera is 1.3 MP, catering mostly to video calls rather than high-quality selfies.
Battery Life
The smartphone is supported by a Li-Ion 2000 mAh battery, a standard capacity for budget-friendly phones from its era. This battery size ensures that the device can last through a day of average use, including calling, messaging, and light browsing. Features like non-demanding processors and low-resolution screens also aid in conserving battery life.
Connectivity
On the connectivity front, the A518 offers GSM and HSPA technology for cellular communication. Wi-Fi 802.11 b/g/n enables wireless internet connectivity, and Bluetooth 2.0 supports basic wireless peripherals and file transfers. It features GPS for navigation purposes and comes with an FM radio, microUSB port, and a 3.5mm headphone jack for listening convenience.
Software
The phone operates on Android 4.4.2 KitKat, a version that was well-regarded for its improved performance and user interface enhancements when compared to previous ones. However, advancements in applications and software demands mean that newer applications may not be compatible or perform optimally.
Conclusion
Overall, the Celkon A518 was designed to meet the needs of budget-conscious consumers requiring fundamental smartphone functionalities. Its design language, basic camera capabilities, sufficient battery life, and connectivity options reflected a sensible choice during its active market period. However, as technology advances, consumer needs evolve towards higher performance benchmarks that the A518 may not satisfy today.
