The Yezz Classic C21 is designed for simplicity and durability, characteristic of many feature phones released in the mid-2010s. The device comes in multiple colors, including Red, Green, Blue, Purple, White, Gray, and Black, offering a range of options for users who want a touch of personal flair. Weighing in at just 73 grams without the battery, it is remarkably lightweight, making it easy to carry around in a pocket or purse. The phone measures 106 x 45 x 14.5 mm, which ensures it fits comfortably in the hand, providing ease of use for calls and text messaging.
The Yezz Classic C21 features a 1.8-inch TFT screen with a resolution of 128 x 160 pixels, offering a pixel density of approximately 114 ppi. While the display size and resolution might seem modest by today’s smartphone standards, it is quite typical for feature phones focused on basic functionalities. The screen can display up to 65K colors, providing sufficient vividness for viewing contacts and text messages clearly.
Designed as a purely functional device rather than a high-performance gadget, the Classic C21 manages basic phone operations with ease. Equipped with 32MB of internal storage and 32MB of RAM, the phone allows users to store essential contacts and messages. For additional storage, there is a microSDHC slot, enabling users to expand their storage capacity for music and other minor files.
In terms of photography, the Yezz Classic C21 includes a basic VGA camera. While this 0.3MP camera does not offer advanced photography features like those found in modern smartphones, it is capable of capturing simple images suitable for quick photo needs. The device does not support video recording, reinforcing its status as a basic communication device rather than a multimedia powerhouse.
A standout feature of the Yezz Classic C21 is its long battery life, thanks to its 600mAh Li-Ion removable battery. Although it might seem small compared to contemporary smartphone batteries, the phone's energy-efficient design allows for up to 150 hours of standby time and up to 4 hours of continuous talk time. This makes it an excellent choice for individuals who prioritize long battery life in a mobile device.
The Classic C21 supports GSM technology, with coverage for GSM 850/900/1800/1900 bands. This ensures wide-ranging network compatibility, especially useful for international travelers. Although the phone lacks modern data connectivity features like 3G or 4G, it supports GPRS with speeds up to 48 kbps, which may suffice for basic internet tasks like checking emails.
With dual SIM capability, the Classic C21 allows users to easily manage two different phone numbers, making it suitable for those who need separate business and personal lines. The device also includes Bluetooth 2.1 for local data sharing and stereo FM radio for entertainment purposes. However, it does not support Wi-Fi connectivity, which aligns with its focus on basics rather than smartphone-like functionalities.
In addition to its core functions, the Yezz Classic C21 includes some essential features like SMS messaging. Notably, the phone does not come with pre-installed games or Java applications, which further reiterates its design focus on communication. The lack of a 3.5 mm headphone jack might be an inconvenience for some users, but the device does have a loudspeaker for hands-free calls.
The Yezz Classic C21 is a quintessential feature phone, aimed at providing basic communication functionality rather than diversified multimedia capabilities. Discontinued since its release in 2014, it nonetheless serves as a practical choice for users who seek simplicity, long battery life, and reliable performance in voice calling and messaging. Its lightweight design and diverse color options add to its appeal as an accessible and straightforward mobile device.
