- Brighter display (508 nits)
- Slower 25W charging
- Potentially higher price
- Similar battery life despite less efficient chipset
Display Comparison
Both the Oppo A77 4G and Samsung Galaxy A23 5G feature displays with a 1328:1 contrast ratio, suggesting similar visual pop. However, the A23 5G edges ahead with a measured peak brightness of 508 nits, offering better visibility in direct sunlight. While neither display is expected to offer high refresh rates, the A23 5G’s higher brightness is a tangible benefit for outdoor use.
Camera Comparison
Both devices are listed as having Photo/Video capabilities, but detailed sensor information is missing. Given the market positioning, it’s likely both rely on primary sensors around the 50MP mark. However, the A23 5G’s more powerful ISP (Image Signal Processor) within the Snapdragon 695 chipset will likely result in better image processing, particularly in low-light conditions. The absence of details suggests neither phone will excel in photography, but the A23 5G has a processing advantage.
Performance
The core difference lies in the chipsets. The Samsung Galaxy A23 5G’s Qualcomm Snapdragon 695 5G (6nm) is a significant upgrade over the Oppo A77 4G’s MediaTek Helio G35 (12nm). The 6nm process node of the Snapdragon 695 translates to improved power efficiency and reduced thermal throttling during sustained tasks. The A23 5G’s CPU configuration – 2x2.2 GHz Kryo 660 Gold & 6x1.7 GHz Kryo 660 Silver – offers a more balanced performance profile than the A77 4G’s 4x2.3 GHz Cortex-A53 & 4x1.8 GHz Cortex-A53. This means smoother multitasking and better performance in demanding applications.
Battery Life
Both phones achieve an endurance rating of 138 hours, indicating similar overall battery life despite the Oppo A77 4G having a smaller battery capacity (not specified). However, the A77 4G compensates with significantly faster 33W wired charging, reaching 100% in just 69 minutes, compared to the A23 5G’s 25W charging. This difference is crucial for users who prioritize quick top-ups over extended runtime.
Buying Guide
Buy the Oppo A77 4G if you prioritize extremely fast charging and don't require 5G connectivity. It's ideal for users who frequently find themselves needing to top up their battery quickly. Buy the Samsung Galaxy A23 5G if you want a phone with 5G support, a more efficient processor, and a slightly brighter display, even if it means slightly slower charging speeds.
Frequently Asked Questions
❓ Is the Snapdragon 695 in the Galaxy A23 5G powerful enough for demanding games like PUBG?
