Display Comparison

The Samsung Galaxy S21+ 5G boasts a significantly brighter display, reaching 883 nits compared to the Tecno Phantom X’s 405 nits. This translates to superior visibility in direct sunlight. While both phones feature an 'Infinite' contrast ratio (typical for AMOLED panels), the S21+'s higher peak brightness and likely superior color calibration (though not specified in the data) provide a more vibrant and accurate visual experience. The Phantom X's contrast ratio is nominal, suggesting it may not achieve the same deep blacks as the S21+.

Camera Comparison

Both devices offer photo and video capabilities, but the context data lacks specifics to make a definitive judgment. However, given Samsung’s established camera expertise and the S21+'s likely superior image signal processor (ISP), it’s reasonable to expect better image quality, particularly in low-light conditions. The absence of sensor size information makes a direct comparison difficult, but Samsung typically employs larger sensors in its flagship devices. The Phantom X’s camera performance will likely be adequate for social media sharing, but the S21+ is expected to deliver more detailed and dynamic images.

Performance

The core difference lies in the chipsets. The Galaxy S21+ 5G, depending on the region, utilizes either the Exynos 2100 (5nm) or the Snapdragon 888 5G (5nm). Both are built on a more advanced 5nm process compared to the Tecno Phantom X’s 12nm Mediatek Helio G95. This process node advantage means the S21+ chips are more power-efficient and capable of sustaining higher performance for longer periods. The S21+'s CPU configuration, featuring a Cortex-X1 prime core, provides a substantial performance uplift over the Phantom X’s Cortex-A76 cores, particularly in single-core tasks. While the Phantom X’s octa-core setup is adequate for daily use, the S21+ excels in demanding applications like gaming and video editing.

Battery Life

The endurance ratings are surprisingly close, with the Tecno Phantom X at 122 hours and the Samsung Galaxy S21+ 5G at 114 hours. This suggests that despite a potentially less efficient chipset, the Phantom X’s battery optimization and lower power draw from its display contribute to comparable battery life. However, the S21+ offers faster charging at 25W (with PD3.0 support) compared to the Phantom X’s 33W, and adds the convenience of 15W wireless and 4.5W reverse wireless charging – features absent on the Phantom X. The Phantom X claims 70% charge in 30 minutes, while the S21+’s 25W charging will likely achieve a similar result, though potentially with less overall efficiency.

Buying Guide

Buy the Tecno Phantom X if you need a large-screen phone with decent battery life and are willing to compromise on peak performance and display quality to stay within a tight budget. Buy the Samsung Galaxy S21+ 5G if you prioritize a premium display, faster processing speeds for demanding applications, and a more refined camera experience, and are willing to pay a premium for it.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the Galaxy S21+ 5G suffer from overheating issues?
Early reports indicated potential thermal throttling with the Exynos 2100, particularly during prolonged gaming sessions. However, software updates from Samsung have largely mitigated these concerns. The 5nm process and improved thermal management solutions contribute to stable performance under most conditions. The Snapdragon 888 variant generally exhibits better thermal performance.
❓ Is the 33W charging on the Tecno Phantom X significantly faster in real-world use than the 25W on the S21+?
While the Phantom X boasts 33W charging, the difference in charging speed is likely marginal. The S21+'s Power Delivery 3.0 support optimizes charging efficiency. Both phones should achieve a substantial charge in around 30 minutes, but the S21+ benefits from the added convenience of wireless charging.
❓ How does the Helio G95 processor handle demanding games like PUBG Mobile on the Tecno Phantom X?
The Helio G95 can run PUBG Mobile, but you'll likely need to lower graphics settings to achieve a consistently smooth frame rate. The S21+'s Snapdragon 888 or Exynos 2100 will provide a significantly smoother and more stable gaming experience at higher settings.
❓ Does the Samsung Galaxy S21+ 5G still receive software updates?
Yes, the Samsung Galaxy S21+ 5G continues to receive software updates, including security patches and feature enhancements. Samsung typically provides several years of software support for its flagship devices.
