The BenQ-Siemens EF91: A Feature-Packed Phone
When it comes to mobile devices, the BenQ-Siemens EF91 may not be the first name that comes to mind. But for those who owned this phone back in 2006, it was a beloved device that offered many features and capabilities.
Release and Specifications
The EF91 was released in February of 2006 and was considered a feature phone. This means that it had more advanced functions than a basic phone, but it wasn't a full-fledged smartphone.
It weighed only 100g and had a thickness of 23.5mm, making it lightweight and easy to carry around. It also had 32MB of internal storage, which could be expanded with a microSD card.
Network and Speed
The EF91 utilized both GSM and HSPA technologies, with 2G bands of GSM 900/1800/1900 and 3G bands of HSDPA 2100. This allowed for fast data speeds, especially for its time.
Thanks to the HSPA speed, users could browse the internet and download content quickly and efficiently.
Design and Display
The phone had a compact design, with dimensions of 92 x 46.5 x 23.5 mm. Its external 2.0-inch TFT display boasted 256K colors and a resolution of 240 x 320 pixels. Additionally, it had a second external display with 65K colors and an OLED screen with a resolution of 96 x 64 pixels.
Camera and Sound
For its time, the EF91's camera was impressive, with a 3.15 MP rear camera with autofocus and LED flash. It also had a VGA front camera for video calls.
The phone also had loudspeaker capabilities and downloadable polyphonic and MP3 ringtones. However, it didn't have a 3.5mm jack but did offer 3D sound for a more immersive listening experience.
Connectivity and Features
The EF91 had limited connectivity options, with no WLAN capability. It did have Bluetooth 1.2 and a proprietary USB port for data transfer.
In terms of features, the phone had sensors for basic functions like messaging and email. It also offered games, a video telephony option, and a music player that supported MP3 and AAC files.
Battery and Color
The EF91 had a removable Li-Ion 1000mAh battery that provided decent battery life for its time. As for its color options, it was only available in Arctic Silver.
Final Thoughts
Although the BenQ-Siemens EF91 is now discontinued, it still offers a glimpse into the past and the advancement of mobile technology at the time. With its compact design, advanced features, and decent camera, it was a popular choice among those looking for a feature phone back in 2006.
