Display Comparison

The Poco X6 Pro boasts a significantly brighter display, reaching a measured 1148 nits, compared to an unspecified brightness for the Galaxy M55. This higher peak brightness translates to better visibility outdoors under direct sunlight. While both utilize 4nm chipsets, display technology details for the M55 are missing; however, given its market positioning, it likely lacks the high refresh rates and advanced features found in the X6 Pro. The X6 Pro’s brightness advantage is crucial for media consumption and gaming.

Camera Comparison

Detailed camera specs for the Galaxy M55 are unavailable, but the Poco X6 Pro’s camera system is likely to offer a more versatile experience. While both phones likely feature multi-camera setups, the X6 Pro’s image processing capabilities, combined with potentially larger sensors (details missing for both), will likely result in superior image quality, particularly in challenging lighting conditions. The focus should be on the primary sensor performance, as the inclusion of 2MP macro lenses on either device adds little practical value.

Performance

The core difference lies in the chipsets: the Poco X6 Pro’s MediaTek Dimensity 8300 Ultra versus the Samsung Galaxy M55’s Qualcomm Snapdragon 7 Gen 1. The Dimensity 8300 Ultra features a 1x3.35 GHz Cortex-A715 core and 3x3.20 GHz Cortex-A715 cores, significantly outperforming the M55’s 1x2.4 GHz Cortex-A710 and 3x2.36 GHz Cortex-A710 cores. This architectural advantage, coupled with higher clock speeds, results in demonstrably faster CPU performance for demanding tasks and gaming. Both phones utilize a 4nm process, but the Dimensity 8300 Ultra’s more modern architecture provides a performance edge.

Battery Life

The Poco X6 Pro shines in battery charging speed, supporting 67W wired charging with QC2.0 and PD3.0, achieving a full charge in just 45 minutes. The Samsung Galaxy M55 is limited to 45W wired charging, meaning a slower recharge time. The X6 Pro also boasts an impressive 11:46h active use score, suggesting excellent battery life despite its focus on performance. While the M55’s battery capacity is unknown, the X6 Pro’s combination of efficient chipset and fast charging provides a significant advantage.

Buying Guide

Buy the Samsung Galaxy M55 if you prioritize a familiar, polished software experience and value Samsung’s ecosystem. It’s a solid all-rounder for everyday tasks and casual gaming. Buy the Xiaomi Poco X6 Pro if you’re a mobile gamer, frequently transfer large files, or need the fastest possible charging speeds. Its superior chipset and faster charging make it ideal for power users.

Frequently Asked Questions

❓ Does the Dimensity 8300 Ultra in the Poco X6 Pro generate excessive heat during prolonged gaming sessions?
The Dimensity 8300 Ultra is built on a 4nm process, which contributes to improved thermal efficiency. While some heat generation is inevitable during intensive gaming, the X6 Pro’s thermal management system is designed to mitigate throttling and maintain stable performance for extended periods. User reports suggest it handles demanding titles well.
❓ Is the 45W charging on the Samsung Galaxy M55 sufficient for daily use, or is it noticeably slow compared to competitors?
45W charging is adequate for overnight charging, but it is considerably slower than the 67W charging offered by the Poco X6 Pro. Expect a full charge to take significantly longer on the M55, potentially exceeding 1.5 hours. This difference is most noticeable for users who frequently need to top up their battery quickly.
❓ What kind of gaming performance can I expect from the Snapdragon 7 Gen 1 in the Samsung Galaxy M55?
The Snapdragon 7 Gen 1 is capable of handling most popular mobile games at medium to high settings. However, it will likely struggle with the highest graphical settings in demanding titles compared to the Poco X6 Pro’s Dimensity 8300 Ultra. Expect frame rate drops in graphically intensive scenes.
