Samsung Galaxy S21 FE 5G

  • Significantly faster processor for gaming and demanding apps
  • Brighter display for better outdoor visibility
  • Wireless charging and reverse wireless charging capabilities

  • Potential for thermal throttling under sustained load
  • May be more expensive than the A73 5G

Samsung Galaxy A73 5G

  • Potentially longer software support lifecycle
  • Modern design and build quality
  • Competitive price point

  • Noticeably slower processor compared to the S21 FE
  • Lacks wireless charging

Display Comparison

The S21 FE 5G boasts a brighter display, reaching a measured 792 nits, compared to the A73 5G (brightness data unavailable, but expected to be lower). While both likely utilize AMOLED panels, the S21 FE’s higher peak brightness translates to better visibility in direct sunlight. The 'Infinite' contrast ratio, common to Samsung AMOLEDs, is present on the S21 FE, suggesting deep blacks and vibrant colors. The A73’s display, while likely good, is expected to be less impactful in bright environments.

Camera Comparison

Both phones feature capable camera systems, but the S21 FE 5G likely holds an edge due to its flagship heritage. While specific sensor details are missing, the S21 FE’s image processing benefits from the more powerful ISP within the Snapdragon 888/Exynos 2100. The A73 5G’s camera is expected to be competent for everyday photography, but may struggle in low-light conditions compared to the S21 FE. The presence of OIS (Optical Image Stabilization) is assumed on both, but the S21 FE’s implementation is likely more refined. We'll disregard the likely inclusion of a 2MP macro lens on the A73, as these sensors rarely deliver significant image quality improvements.

Performance

The core difference lies in the chipsets. The S21 FE 5G utilizes either the Qualcomm Snapdragon 888 5G (5nm) or the Exynos 2100 (5nm), both built on a 5nm process. This contrasts with the A73 5G’s Snapdragon 778G 5G (6nm). The Snapdragon 888/Exynos 2100’s octa-core configuration, featuring a Cortex-X1 prime core clocked up to 2.9GHz, delivers substantially higher CPU and GPU performance. The A73’s Cortex-A78 prime core at 2.4GHz is capable, but cannot match the flagship-level processing power. The 5nm process of the S21 FE’s chips also contributes to better thermal efficiency, potentially reducing throttling during sustained workloads.

Battery Life

The S21 FE 5G achieves an endurance rating of 92 hours, indicating solid battery life. Both phones support 25W wired charging, with the S21 FE offering 50% charge in 30 minutes. The A73 lacks wireless charging, a feature present on the S21 FE (15W wireless and reverse wireless). While the A73 may have a slightly larger battery capacity (data unavailable), the S21 FE’s more efficient chipset and optimized software could offset this difference, resulting in comparable real-world battery performance.

Buying Guide

Buy the Samsung Galaxy S21 FE 5G if you need a phone capable of handling demanding games, intensive multitasking, and benefit from a significantly brighter display for outdoor visibility. Buy the Samsung Galaxy A73 5G if you prefer a more balanced device with a focus on battery life, a modern design, and a potentially lower price point, prioritizing everyday usability over peak performance.

Frequently Asked Questions

❓ Does the Exynos 2100 version of the S21 FE 5G suffer from overheating issues?
Early reports indicated some thermal throttling with the Exynos 2100 variant, particularly during prolonged gaming sessions. However, software updates have mitigated these issues to a degree. The Snapdragon 888 version generally exhibits better thermal performance, but the difference is less pronounced with current software optimizations.
❓ Is the Snapdragon 778G in the A73 5G powerful enough for demanding games like PUBG or Genshin Impact?
The Snapdragon 778G can run PUBG and Genshin Impact, but you'll likely need to lower graphics settings to achieve a smooth frame rate. It's suitable for casual gaming, but won't deliver the same high-fidelity experience as the S21 FE 5G.
❓ How does the software update policy differ between the S21 FE and A73?
The S21 FE, being a former flagship, initially received more frequent and longer-term software support. However, both devices are now nearing the end of their major Android update cycle. The A73 may receive security updates for a slightly longer period due to its later release date.
❓ What are the real-world benefits of the 6nm process used in the Snapdragon 778G compared to the 5nm process in the Snapdragon 888/Exynos 2100?
The 6nm process generally offers improved power efficiency compared to older nodes, but the 5nm process is still more efficient. While the A73 benefits from the 6nm node, the S21 FE's more powerful chipset and optimized software still result in superior overall performance and efficiency.
