  • Significantly weaker processor
  • Slower charging speed
  • Likely less vibrant display

Xiaomi Poco X6 Pro

  • Much faster and more efficient processor

  • Brighter display for better outdoor visibility

  • Higher price tag
  • Xiaomi’s MIUI software can be polarizing
  • Potentially less long-term software support compared to Samsung

Display Comparison

The Poco X6 Pro boasts a significantly brighter display, reaching a measured peak of 1148 nits. This translates to superior visibility outdoors under direct sunlight compared to the Galaxy F15, whose brightness is not specified but is likely lower given its positioning. While both likely utilize LCD panels (based on market segment), the X6 Pro’s higher brightness is a clear advantage. The absence of information on refresh rates or panel technology (LTPO) for the F15 suggests a more basic display experience.

Camera Comparison

While both phones feature cameras, the context data is limited. The Poco X6 Pro likely features a more sophisticated camera system, given its higher price point and Xiaomi’s focus on camera technology. We can infer that the X6 Pro will offer better image processing and potentially larger sensor sizes. The Galaxy F15’s camera is likely adequate for casual photography, but will likely fall short in low-light conditions and detail capture. The absence of sensor size details for either phone makes a precise comparison difficult, but the X6 Pro’s overall positioning suggests a more capable camera experience.

Performance

The performance gap between these devices is substantial. The Poco X6 Pro’s MediaTek Dimensity 8300 Ultra (4nm) is a powerhouse, featuring a 1x3.35 GHz Cortex-A715 core and three additional Cortex-A715 cores, alongside four Cortex-A510 cores. This contrasts sharply with the Galaxy F15’s Dimensity 6100+ (6nm), which uses older Cortex-A76 and A55 cores. The 4nm process of the X6 Pro’s chip also offers better power efficiency, reducing thermal throttling during sustained workloads. This means the X6 Pro will handle demanding games and applications with greater ease and consistency.

Battery Life

The Poco X6 Pro demonstrates a clear advantage in battery endurance, achieving an active use score of 11:46h. While the Galaxy F15’s battery capacity is not specified, the X6 Pro’s superior efficiency, combined with its 67W fast charging (capable of 100% charge in 45 minutes with QC2.0 and PD3.0 support), provides a significant convenience factor. The F15’s 25W charging is considerably slower, requiring more downtime to replenish the battery. The X6 Pro’s faster charging is particularly beneficial for users who frequently use power-intensive applications.

Buying Guide

Buy the Samsung Galaxy F15 if you need a reliable, everyday smartphone with a focus on affordability and long-term software support. It's ideal for users who primarily browse, use social media, and make occasional calls. Buy the Xiaomi Poco X6 Pro if you prioritize gaming, demanding multitasking, and fast charging. This phone is geared towards power users who want a responsive experience and don't mind a less-known brand.

Frequently Asked Questions

❓ Does the Dimensity 8300 Ultra in the Poco X6 Pro get hot during extended gaming sessions?
The Dimensity 8300 Ultra is built on a 4nm process, which inherently offers better thermal efficiency than the 6nm Dimensity 6100+ in the Galaxy F15. While some heat generation is inevitable during prolonged gaming, the X6 Pro is designed to manage temperatures effectively, minimizing throttling and maintaining consistent performance. The larger surface area of the phone also aids in heat dissipation.
❓ How does the software experience differ between Samsung's One UI and Xiaomi's MIUI on these phones?
Samsung's One UI is generally considered more polished and user-friendly, with a cleaner interface and a focus on simplicity. Xiaomi's MIUI, while feature-rich, can be more cluttered and includes a greater degree of customization. MIUI also tends to include more pre-installed apps (bloatware) than One UI. Software preference is subjective, but One UI is often favored by users seeking a streamlined experience.
❓ Is the 25W charging on the Galaxy F15 slow enough to be a major inconvenience?
Yes, 25W charging is significantly slower than the 67W charging on the Poco X6 Pro. While it will still charge the phone overnight, topping up quickly during the day will take considerably longer. For users who frequently find themselves needing a quick boost, the slower charging speed of the F15 can be a noticeable drawback.
