Display Comparison

The Moto G51 5G boasts a measured peak brightness of 595 nits, significantly outshining the G42. Its 1634:1 contrast ratio is also impressive. The G42's display is likely adequate but won't offer the same vibrancy or visibility in bright sunlight. Both phones likely feature similar resolution (FHD+), but the G51's brightness is a key differentiator.

Camera Comparison

Camera performance is a bit more nuanced. While both phones offer 'Photo / Video' capabilities (specific megapixels are missing), the G42's Snapdragon 680 is often paired with better camera software optimization. The G51 5G's camera is likely decent, but the G42 might offer slightly better image processing and low-light performance. Both likely feature a main sensor, ultrawide, and macro lens.

Performance

The Moto G51 5G's Snapdragon 480+ 5G offers a noticeable performance edge over the G42's Snapdragon 680 4G, especially when considering 5G connectivity. While both are budget chipsets, the 480+ generally handles multitasking and demanding apps slightly better. The G42's 6nm process offers better power efficiency, though.

Battery Life

The Moto G51 5G's endurance rating of 124h is exceptional, suggesting excellent battery life. The G42, with its more efficient Snapdragon 680, likely also provides solid battery life, though potentially not quite as impressive as the G51 5G. Charging speeds are a drawback for both, with the G51 5G varying between 10W and 20W depending on the region, and the G42 at 18W.
