  • Likely higher quality display with high refresh rate

  • Shorter battery life compared to the Phantom X
  • Higher price tag
  • Gaming-focused design may not appeal to all users

Display Comparison

The Tecno Phantom X features a display with a measured peak brightness of 405 nits, which is adequate for indoor use but may struggle in direct sunlight. While the contrast ratio is nominally infinite, this is typical of OLED panels and doesn't necessarily translate to superior image quality. The ROG Phone 5s, while lacking specific brightness data, benefits from a higher refresh rate (typically 144Hz on ROG Phones) which is crucial for smooth gaming. The ROG Phone's display technology is geared towards responsiveness, while the Phantom X prioritizes power efficiency. The lack of detailed display specs for the ROG Phone 5s necessitates relying on the brand's reputation for high-quality gaming displays.

Camera Comparison

Both devices offer photo and video capabilities, but detailed sensor information is limited for the Tecno Phantom X. The ROG Phone 5s, while primarily a gaming phone, typically includes a capable camera system. Without specific sensor sizes or aperture details for the Phantom X, it's difficult to make a direct comparison. However, ROG Phones often prioritize image processing for vibrant colors and detail, catering to social media sharing. The absence of information regarding OIS (Optical Image Stabilization) on either device makes it difficult to assess low-light performance. It's safe to assume the ROG Phone 5s will offer a more refined camera experience due to its higher-end positioning.

Performance

The core difference lies in the chipsets. The Asus ROG Phone 5s boasts the Qualcomm Snapdragon 888+ 5G (5nm), a flagship processor with an octa-core configuration featuring a Cortex-X1 prime core clocked at 2.99 GHz. This architecture provides a substantial performance leap over the Tecno Phantom X’s MediaTek Helio G95 (12nm). The G95, while capable, is a mid-range chip with a Cortex-A76 based core configuration. The 5nm fabrication process of the Snapdragon 888+ also offers superior thermal efficiency, reducing throttling during sustained gaming sessions. This translates to consistently higher frame rates and smoother gameplay on the ROG Phone 5s. The ROG Phone 5s also benefits from faster RAM (likely LPDDR5) compared to the Phantom X, further enhancing performance.

Battery Life

The Tecno Phantom X shines in battery endurance, achieving a measured 122 hours on a single charge. This is a significant advantage for users who prioritize all-day battery life. The Asus ROG Phone 5s, designed for power-intensive gaming, likely has a shorter endurance rating. While the ROG Phone 5s offers faster charging at 65W (70% in 30 minutes, 100% in 52 minutes) and even 10W reverse wired charging, the Phantom X’s 33W charging (70% in 30 minutes) is still respectable. The ROG Phone 5s’ faster charging mitigates some of the battery life concerns, but the Phantom X remains the clear winner for longevity.

Buying Guide

Buy the Tecno Phantom X if you need a reliable smartphone with exceptional battery life for everyday tasks, media consumption, and light gaming, and are on a tighter budget. Buy the Asus ROG Phone 5s if you are a serious mobile gamer who demands the highest frame rates, responsive controls, and advanced cooling solutions, and are willing to compromise on battery life for peak performance.
