  • Slower processor (Snapdragon 765G)
  • Slower charging speed (18W)

Display Comparison

The Pixel 5a 5G boasts a brighter display, reaching a measured 861 nits, compared to the Realme X3’s unspecified peak brightness. This translates to better outdoor visibility for the Pixel. While both offer an 'infinite' contrast ratio (typical for OLED panels), the Pixel’s superior brightness is a tangible advantage. The Realme X3’s display technology is not specified, but given its market positioning, it likely lacks features like adaptive refresh rates found in higher-end devices, potentially resulting in a less fluid visual experience than some competitors.

Camera Comparison

While detailed camera specs are limited, the Pixel 5a 5G is expected to excel in image processing due to Google’s computational photography expertise. The Realme X3’s camera system is less emphasized in available data, suggesting a more standard approach. The Pixel’s strength lies in its ability to produce consistently excellent photos in various lighting conditions, leveraging software algorithms to enhance detail and dynamic range. The absence of detailed sensor information for the Realme X3 makes a direct comparison difficult, but it’s unlikely to match the Pixel’s software-driven image quality.

Performance

The Realme X3’s Snapdragon 855+ is a significant step up in processing power compared to the Pixel 5a 5G’s Snapdragon 765G. The 855+ features a Kryo 485 core clocked at 2.96 GHz, while the 765G tops out at 2.4 GHz with its Kryo 475 Prime core. This difference is noticeable in benchmarks and real-world performance, particularly in demanding games. However, the 765G’s architecture is more efficient, potentially leading to better sustained performance under load, mitigating thermal throttling. The Realme X3’s performance advantage comes at the cost of potentially higher power consumption.

Battery Life

Both phones achieve an endurance rating of 122 hours, indicating similar overall battery life despite differing battery capacities (not specified for the X3). However, the charging speeds differ significantly. The Realme X3 supports 30W wired charging, reaching 100% in 55 minutes, while the Pixel 5a 5G is limited to 18W with PD2.0. This means the Realme X3 can be topped up much faster, a crucial advantage for users who frequently need a quick power boost. The Pixel’s efficiency may compensate for the slower charging, but the X3 offers greater convenience.

Buying Guide

Buy the Realme X3 if you need uncompromising performance for gaming, video editing, or other resource-intensive applications and are comfortable with a less polished software experience. Buy the Google Pixel 5a 5G if you prioritize a clean Android experience, exceptional camera quality, and long-term software support, even if it means sacrificing some raw processing power.

Frequently Asked Questions

❓ Does the Snapdragon 765G in the Pixel 5a 5G struggle with demanding games like Genshin Impact?
While the Snapdragon 765G is capable, it won't deliver the same peak frame rates as the Snapdragon 855+ in the Realme X3. You'll likely need to lower graphics settings for a smooth experience in graphically intensive titles. The Pixel 5a 5G prioritizes efficiency over raw power, so sustained performance might be better due to less thermal throttling.
❓ How does Realme's UI compare to the stock Android experience on the Pixel 5a 5G?
Realme UI is a heavily customized Android skin with a different aesthetic and feature set compared to the Pixel 5a 5G’s stock Android. Pixel’s software is known for its simplicity, speed, and timely updates directly from Google. Realme UI offers more customization options but can feel bloated to some users.
❓ Is the lack of a microSD card slot on either phone a significant limitation?
For users with large media libraries or who frequently record high-resolution videos, the lack of microSD card expansion on both devices could be a limitation. Cloud storage solutions are viable alternatives, but require a stable internet connection and may incur subscription costs.
