LG Q51

  • Extremely affordable price point
  • Acceptable for basic smartphone tasks
  • Potentially longer battery life in light use

  • Outdated and slow Helio P22 chipset
  • Limited performance for demanding apps
  • Likely inferior camera quality

Google Pixel 4a 5G

  • Powerful Snapdragon 765G processor
  • 5G connectivity for faster data speeds
  • Excellent camera with Google’s image processing

  • Higher price than the LG Q51
  • LCD display isn't as vibrant as OLED
  • May require more frequent charging with heavy use

Display Comparison

Neither device boasts a standout display. The LG Q51’s display specifications are not provided, but given its market segment, it likely features a 720p+ LCD panel. The Pixel 4a 5G, while also utilizing an LCD, benefits from a larger 6.57-inch size and a higher resolution. The Snapdragon 765G’s image signal processor also contributes to better display calibration. The Q51’s panel is likely to exhibit lower brightness and narrower color gamut, impacting outdoor visibility and media consumption.

Camera Comparison

The Pixel 4a 5G’s camera system is a clear advantage. While specific sensor details for the LG Q51 are unavailable, its price point suggests a basic camera setup. The Pixel 4a 5G benefits from Google’s renowned computational photography, leveraging the Snapdragon 765G’s ISP for superior image processing. The 4a 5G’s image processing excels in dynamic range and low-light performance, delivering consistently high-quality photos. The Q51 will likely produce acceptable images in good lighting conditions, but will fall short in challenging scenarios.

Performance

The performance gap between these two devices is substantial. The Google Pixel 4a 5G’s Qualcomm Snapdragon 765G (7nm) is a far more advanced chipset than the LG Q51’s MediaTek Helio P22 (12nm). The Snapdragon 765G’s octa-core CPU, with its Kryo 475 cores (Prime, Gold, and Silver), offers significantly faster processing speeds – 2.4GHz peak vs. 2.0GHz on the Q51. The 7nm process node also translates to better power efficiency and reduced thermal throttling. This means the Pixel 4a 5G will handle demanding apps and multitasking with ease, while the Q51 will struggle with anything beyond basic usage.

Battery Life

Battery life is a complex equation. The LG Q51’s battery capacity is not specified, but its less powerful chipset and lower-resolution display may result in comparable, or even slightly better, battery endurance in light usage scenarios. However, the Pixel 4a 5G’s 18W fast charging with PD2.0 support significantly reduces downtime. While the Q51’s charging speed is unknown, it’s unlikely to match the Pixel’s efficiency. The Snapdragon 765G’s power efficiency also contributes to overall battery management, even with 5G enabled.

Buying Guide

Buy the LG Q51 if you prioritize extreme affordability and only need a smartphone for basic tasks like calls, texts, and light social media use. You’re willing to compromise on performance and future-proofing. Buy the Google Pixel 4a 5G if you want a responsive user experience, 5G connectivity, a significantly better camera, and guaranteed software updates – even if it means spending a bit more upfront.

Frequently Asked Questions

❓ Will the LG Q51 struggle with modern mobile games like PUBG or Call of Duty?
Yes, the MediaTek Helio P22 is a low-end chipset that will likely struggle to run demanding games like PUBG or Call of Duty smoothly, even on low settings. Expect significant frame rate drops and potential lag. The Pixel 4a 5G’s Snapdragon 765G is far better equipped for gaming.
❓ How much faster is the Pixel 4a 5G's 5G connectivity compared to 4G on the LG Q51?
5G speeds on the Pixel 4a 5G can be significantly faster than 4G on the LG Q51, potentially offering download speeds several times higher depending on network availability. However, 5G coverage is still limited, so the real-world benefit will vary based on your location.
❓ Does the Pixel 4a 5G receive regular software updates and security patches?
Yes, the Google Pixel 4a 5G is guaranteed to receive regular software updates and security patches directly from Google for several years. This is a major advantage over the LG Q51, which may receive limited or no updates from LG.
