Display Comparison

Both devices feature a nominal contrast ratio of 928:1, indicating decent image quality for their time. The Sidekick 4G had a 3.2-inch display, while the Xperia Pro boasted a 4.1-inch screen, giving it a slight advantage in terms of screen real estate. However, resolution was limited on both, so don't expect modern sharpness.

Camera Comparison

Camera capabilities were basic on both devices. Both featured Photo/Video functionality, but image quality was limited by the sensors and processing power of the time. Expect grainy images and low-light performance that's far from ideal by today's standards. Neither phone was a photography powerhouse.

Performance

The Xperia Pro's Qualcomm Snapdragon S2 chipset (1.0 GHz Scorpion) generally outperformed the Sidekick 4G's Hummingbird (1.0 GHz Cortex-A8). While both CPUs are similarly clocked, the Snapdragon architecture offered better efficiency and performance in real-world usage. App loading times and multitasking were noticeably smoother on the Xperia Pro.

Battery Life

The Xperia Pro shines in this category. Its endurance rating of 37 hours significantly surpasses what the Sidekick 4G could achieve. The Sidekick 4G's battery life was considerably shorter, requiring more frequent charging.

Buying Guide

The T-Mobile Sidekick 4G is for those seeking a nostalgic experience and a dedicated messaging device. The Sony Ericsson Xperia Pro is for users who appreciate a compact form factor, a physical keyboard, and a longer-lasting battery, and are willing to overlook its age.

Frequently Asked Questions

❓ Are these phones still usable in 2024?
Yes, but with significant limitations. Network compatibility is a major concern, as 3G networks are being phased out. Software updates are non-existent, so security vulnerabilities are a risk. They are best suited for nostalgic use or as collector's items.
❓ Which phone is easier to find?
Both are rare, but the Sidekick 4G might be slightly more common due to its wider initial release. Expect to pay a premium for either device due to their collectibility.
