The O2 Cocoon, announced in June 2007, was a feature phone that operated on GSM and HSPA technologies. It supported 2G bands in GSM 850/900/1800/1900 frequencies and a 3G band in HSDPA 2100. With a speed capability of 384 kbps, it offered moderate connectivity performance for its time, although it pales in comparison to modern standards.
Encased in a compact body measuring 94 x 49 x 21 mm and weighing 114 grams, the O2 Cocoon was a device designed for easy handling and portability. Its sleek white exterior encased a Mini-SIM, making it a product designed with simplicity and functionality in mind. Though its design appears outdated today, at the time, it provided a sophisticated aesthetic appeal that attracted fashion-conscious users.
The device featured a 2.28-inch TFT display that supported 256K colors, offering a resolution of 240 x 320 pixels with a 4:3 ratio. The screen was relatively small, covering approximately 35% of the phone’s body, but it was sufficient for navigating the phone's basic functionalities. The 175 ppi density ensured decent clarity in displaying text and images for a feature phone.
With internal storage of 2GB, the O2 Cocoon was on par with other devices in its category during its release year. It supported a microSD card, providing additional storage options for users who needed more space for their contacts, photos, and downloaded content. The phonebook could hold up to 1000 entries with photocall capability, and it also logged the last 20 dialed, received, and missed calls, offering efficient call management.
Equipped with a 2 MP main camera with autofocus and LED flash, the O2 Cocoon allowed users to capture basic photographs and videos. While it lacked advanced features found in current smartphones, its autofocus capability was considered a valuable addition. The device also featured a secondary videocall camera, although its quality and utility were limited at the time.
Known for having a loudspeaker and a 3.5mm audio jack, the O2 Cocoon enabled users to enjoy music through its stereo FM radio and tunes via MP3 ringtones. The device supported vibration alerts and downloadable polyphonic ringtones, enhancing the overall multimedia experience.
While lacking WLAN support, the O2 Cocoon featured Bluetooth 2.0 with A2DP for wireless audio streaming, as well as USB 2.0 connectivity for data transfer. Despite the absence of advanced positioning technologies like GPS, the phone catered to the essential communication needs of its era.
The Cocoon was pre-installed with Java, allowing users to download and play games such as Tetris, Ice Hockey, and Sims2. It supported essential messaging services like SMS, MMS, and Email. The browser capabilities included WAP 2.0/xHTML and HTML, providing access to basic internet browsing.
Fitted with a removable Li-Ion battery, the phone offered a standby time of up to 350 hours and a talk time of up to 5 hours, which was fairly standard for feature phones at the time. Its battery efficiency and removable design allowed users to replace the battery if necessary, extending the phone’s usability.
Offered solely in a white color, the O2 Cocoon didn't provide users a choice in aesthetics, focusing instead on its unique form and display features. While it had been discontinued by now, at its time of release, it was a product that combined simplicity and essential mobile functionalities.
In audio tests, the O2 Cocoon's loudspeaker registered voices and noise at 65dB, and ringing at 78dB, indicating a reasonable sound experience for daily usage. Its audio quality illustrated noise levels of -80.1dB and crosstalk of -79.6dB, maintaining functional audio clarity and performance.
Overall, the O2 Cocoon represented a blend of basic mobile communication needs packaged in a stylish design. While it lacked many contemporary smartphone features, it met the fundamental requirements for personal and multimedia use in a compact and aesthetically pleasing form. As a discontinued model, it now serves as a reminder of how far mobile technology has evolved over the past decades.
