The Sony Xperia SX SO-05D was a versatile device supporting a wide array of technologies. It operated on GSM, HSPA, and LTE networks, making it quite flexible in terms of connectivity. The device supported 2G bands including GSM 850, 900, 1800, and 1900 MHz. For 3G, it covered HSDPA 2100 and 800 MHz, and for 4G connectivity, it supported band 1. The speeds were competitive for its time, with HSPA reaching up to 14.4 Mbps and LTE Cat2 supporting 50 Mbps download and 25 Mbps upload speeds.
Announced in May 2012 and released later in September 2012, the Sony Xperia SX SO-05D was introduced to the market as a compact smartphone option. However, despite its impressive specifications, it has been discontinued, which is common for smartphones as they are replaced by newer models over time.
The dimensions of the Xperia SX SO-05D were 115 x 54 x 9.4 mm, making it one of the more compact devices of its era. Its weight stood at just 95 g, contributing to its portability. The device utilized a Micro-SIM card. The build was sturdy enough for regular use, with a scratch-resistant glass to offer some protection against minor accidents.
The device featured a 3.7-inch LED-backlit LCD display, which provided decent visibility and color reproduction considering the period it was released in. The screen had a resolution of 540 x 960 pixels, resulting in a pixel density of approximately 298 ppi. This display quality ensured sharp visuals for various applications, though it was relatively limited by today’s standards.
The Xperia SX SO-05D operated on Android 4.0 Ice Cream Sandwich. It was powered by the Qualcomm MSM8960 Snapdragon S4 Plus chipset, which was considered efficient at the time. The CPU was a dual-core Krait processor running at 1.5 GHz, paired with an Adreno 225 GPU that catered to the graphical needs of the device. Although not groundbreaking by today's benchmarks, this combination offered a smooth performance for basic tasks and moderate media consumption in 2012.
The SX SO-05D came with 1GB of RAM, sufficient for managing the Android Ice Cream Sandwich OS and multitasking between applications. Internal storage was limited to 4GB, though this could be expanded via a microSDHC card slot, providing additional space for media files and apps, a necessary feature for many users given the limited onboard storage.
The Sony Xperia SX featured an 8 MP rear camera with autofocus and LED flash. It offered panorama mode and recorded videos at 1080p@30fps, enabling decent video recording quality. On the front, it housed a VGA camera, which was fairly basic and designed primarily for video calls rather than high-quality selfies.
The phone featured a loudspeaker and a standard 3.5mm audio jack, allowing users to connect a variety of headphones and external speakers. This contributed to the device’s versatility in terms of audio output and compatibility with numerous audio accessories available at the time.
Connectivity options on the Xperia SX SO-05D were plentiful. It supported Wi-Fi standards 802.11 a/b/g/n, Wi-Fi Direct, DLNA, and hotspot capabilities. Bluetooth 3.1 with A2DP provided wireless connectivity options, while GPS, A-GPS, and GLONASS facilitated reliable positioning services. Interestingly, the phone also included an infrared port, a feature that has become less common in smartphones today. Stereo FM radio with RDS and microUSB 2.0 (with MHL TV-out) were also part of its communication suite.
Sensors included an accelerometer, gyro, proximity, and compass, which enhanced the phone’s functionality in handling apps that required such inputs including navigation and gaming apps. The device did not skimp on essential features despite its compact form factor.
Equipped with a removable Li-Ion 1500 mAh battery, the Xperia SX SO-05D offered decent battery performance for its time. In standby mode, it could last up to 280 hours on 2G and 360 hours on 3G networks. Talk time was recorded at up to 6 hours on 2G and approximately 5 hours and 50 minutes on 3G, which was reasonably adequate for a user’s daily communication needs in 2012.
For personalization, the Xperia SX SO-05D was offered in various color options, including Black, White, Pink, and Orange. The SAR values were documented at 1.07 W/kg for the head and 0.51 W/kg for the body, reflecting its compliance with radiation standards. The device was priced around 220 EUR when it debuted, making it a competitively priced option in its segment.
