Realme GT2 Explorer Master
- Exceptional battery life (126h endurance)
- Competitive 100W wired charging
- Potentially better sustained performance due to battery capacity
- Lower peak display brightness compared to Xiaomi
- Camera details are unknown, potentially less advanced
Xiaomi 12S Ultra
- Brighter display (1065 nits)
- Faster wired and wireless charging options
- Potential for superior camera image processing
- Significantly shorter battery life (93h endurance)
- Reliance on frequent charging
Display Comparison
The Xiaomi 12S Ultra boasts a notably brighter display, reaching a measured 1065 nits compared to the Realme GT2 Explorer Master’s 798 nits. This translates to better visibility under direct sunlight. Both displays share an 'Infinite' (nominal) contrast ratio, suggesting excellent black levels. While both likely utilize AMOLED technology, the Xiaomi’s higher peak brightness is a clear advantage for media consumption and outdoor use. However, the Realme’s brightness is still very good and will be sufficient for most users.
Camera Comparison
Both phones feature capable camera systems, but detailed sensor information is lacking. The context data only indicates 'Photo / Video' capabilities. Given Xiaomi’s history with flagship camera technology, the 12S Ultra likely prioritizes image processing and sensor size. The absence of specific details prevents a thorough comparison, but Xiaomi’s flagship models often excel in low-light photography and dynamic range. The Realme GT2 Explorer Master likely offers a balanced camera experience, but may not reach the same level of sophistication as the Xiaomi.
Performance
Both devices are equipped with the Qualcomm SM8475 Snapdragon 8+ Gen 1 (4 nm) chipset, featuring the same Octa-core CPU configuration (1x3.19 GHz Cortex-X2, 3x2.75 GHz Cortex-A710, and 4x1.80 GHz Cortex-A510). This means raw processing power will be nearly identical. The 4nm fabrication process ensures efficient thermal management, minimizing throttling during extended gaming sessions. The Realme GT2 Explorer Master’s advantage may lie in its potentially more aggressive cooling solution, though specific details are unavailable. RAM configurations are not specified, but both are expected to utilize fast LPDDR5X RAM.
Battery Life
The Realme GT2 Explorer Master’s endurance rating of 126 hours significantly surpasses the Xiaomi 12S Ultra’s 93 hours. This difference is substantial and indicates the Realme will last considerably longer on a single charge. While the Xiaomi 12S Ultra compensates with faster charging – 67W wired (41 minutes to 100%), 50W wireless (52 minutes to 100%), and 10W reverse wireless – the Realme’s 100W wired charging is still competitive. The Xiaomi’s wireless charging is a unique advantage, but the Realme’s longer battery life may negate the need for frequent top-ups.
Buying Guide
Buy the Realme GT2 Explorer Master if you need exceptional battery life and prioritize sustained performance throughout the day. It’s ideal for power users, travelers, or anyone who frequently finds themselves away from a charger. Buy the Xiaomi 12S Ultra if you value a brighter, more vibrant display and appreciate the convenience of faster wired and wireless charging, even if it comes at the cost of overall endurance.
