Motorola Moto G100 (2021)

  • Excellent battery endurance (100h rating)
  • More affordable price point
  • Solid Snapdragon 870 performance

  • Slow 20W charging
  • Significantly lower peak display brightness
  • Older chipset compared to the competition

Realme GT 8 Pro

  • Blazing-fast 120W charging
  • Superior performance with Snapdragon 8 Elite Gen 5
  • Much brighter display (2262 nits)

  • Shorter battery endurance rating (60:32h)
  • Higher price tag
  • Potential for more heat generation under sustained load (though mitigated by 3nm process)

Display Comparison

The Realme GT 8 Pro’s display is a standout feature, achieving a measured peak brightness of 2262 nits, dwarfing the Moto G100’s 613 nits. This translates to significantly better visibility outdoors. While the Moto G100 offers a respectable 1427:1 contrast ratio, the GT 8 Pro’s brightness advantage is more impactful for everyday use. We lack panel technology details for both, but the brightness difference is the key differentiator. The GT 8 Pro’s display is simply more usable in bright conditions.

Camera Comparison

Context data is limited regarding camera specifics. However, given the market positioning, we can infer that the Realme GT 8 Pro likely features a more advanced camera system. The focus should be on the main sensor size and aperture. A larger sensor and wider aperture will capture more light, resulting in better low-light performance. The Moto G100’s camera is likely competent, but the GT 8 Pro is expected to offer superior image quality and video capabilities, assuming it follows Realme’s recent camera trends. We'll need to ignore any 2MP macro lenses on both devices as they offer minimal value.

Performance

The core difference lies in the chipsets. The Realme GT 8 Pro’s Snapdragon 8 Elite Gen 5 (3nm) represents a generational leap over the Moto G100’s Snapdragon 870 (7nm). The 8 Elite Gen 5’s Oryon V3 Phoenix cores, clocked up to 4.6 GHz, deliver significantly higher CPU and GPU performance. The 3nm process node also contributes to improved thermal efficiency, potentially reducing throttling during sustained workloads. While the Moto G100’s Snapdragon 870 is still capable, the GT 8 Pro offers a demonstrably smoother and faster experience, especially in demanding games and applications.

Battery Life

The Moto G100 boasts an impressive 100-hour endurance rating, suggesting excellent battery life. However, the Realme GT 8 Pro compensates for its 60:32h endurance with incredibly fast charging. The GT 8 Pro’s 120W wired charging can reach 50% in just 15 minutes and 100% in 43 minutes, a massive advantage over the Moto G100’s 20W charging. The GT 8 Pro also supports 50W wireless charging and even reverse wireless/wired charging, offering unparalleled versatility. The 1100 cycle rating suggests the GT 8 Pro's battery will maintain capacity longer than the Moto G100's.

Buying Guide

Buy the Motorola Moto G100 (2021) if you prioritize long-lasting battery life and a more affordable price point, and aren't heavily reliant on the absolute fastest processing speeds. Buy the Realme GT 8 Pro if you demand top-tier performance, incredibly fast charging, and are willing to pay a premium for the latest technology. Gamers and power users will find the GT 8 Pro particularly compelling.
