Display Comparison
Both devices list a 'Contrast ratio: Infinite (nominal)', suggesting standard LCD panels without the dynamic range of OLED displays. Without specific brightness data, it's difficult to assess visual clarity in direct sunlight. The Realme X’s display technology is likely older, potentially lacking features like high refresh rates found in more recent Motorola offerings. Bezels are also likely larger on the Realme X due to its age.
Camera Comparison
Both phones are listed with 'Photo / Video' capabilities, lacking specific details. This suggests neither device is a camera-focused flagship. Without sensor size or aperture information, a direct comparison is impossible. However, given the age difference, the Moto G100S likely benefits from improved image processing algorithms and potentially a more modern sensor. The absence of detail suggests both likely rely on software enhancements to compensate for limitations in hardware.
Performance
The Motorola Moto G100S’s Qualcomm SM6435-AA Snapdragon 6s Gen 4 (4nm) represents a substantial leap forward in efficiency compared to the Realme X’s Qualcomm SDM710 Snapdragon 710 (10nm). The 4nm process allows for higher transistor density and lower power consumption, translating to less heat and sustained performance. The G100S’s CPU configuration – Octa-core (4x2.4 GHz Cortex-A78 & 4x1.8 GHz Cortex-A55) – features newer Cortex-A78 cores, offering a performance uplift over the Kryo 360 cores in the Realme X (2x2.2 GHz Kryo 360 Gold & 6x1.7 GHz Kryo 360 Silver). This difference will be most noticeable in demanding applications and games.
Battery Life
The Realme X boasts an impressive 86-hour endurance rating, a significant advantage. However, the Motorola Moto G100S compensates with 30W wired charging, allowing for a 0-100% charge in a shorter timeframe than the Realme X’s 20W charging (55% in 30 minutes). While the Realme X will last longer on a single charge, the G100S’s faster charging reduces downtime, making it more convenient for users who frequently top up their battery.
Buying Guide
Buy the Realme X if your absolute priority is maximizing battery life and you primarily engage in light tasks like calling, texting, and social media. Its 86-hour endurance rating is a standout feature. Buy the Motorola Moto G100S if you prioritize smoother multitasking, gaming, and future-proofing, and appreciate faster charging speeds. The newer chipset provides a more responsive experience and better long-term value.
Frequently Asked Questions
❓ How much faster is the Snapdragon 6s Gen 4 in the Moto G100S compared to the Snapdragon 710 in the Realme X for gaming?
While a precise percentage is difficult to quantify without benchmarks, the Snapdragon 6s Gen 4’s newer CPU cores (Cortex-A78) and more efficient 4nm process will result in noticeably smoother frame rates and reduced thermal throttling in demanding games compared to the Snapdragon 710. Expect a more consistent gaming experience on the Moto G100S.
❓ Does the faster charging on the Moto G100S make up for the potentially shorter battery life compared to the Realme X?
For many users, yes. The 30W charging on the Moto G100S allows for a quick top-up, minimizing downtime. While the Realme X offers longer overall battery life, the convenience of faster charging can be more valuable for those who don't want to wait hours for a full charge.
❓ Are there any known overheating issues with the Snapdragon 6s Gen 4 in the Moto G100S?
The Snapdragon 6s Gen 4 is designed for efficiency, and reports of significant overheating are rare. The 4nm process helps to dissipate heat more effectively than the 10nm process used in the Snapdragon 710. However, sustained heavy usage will still generate some heat, as with any smartphone.
