Oppo A77
- Faster CPU performance with Dimensity 810
- Faster 33W charging
- Potentially better for demanding apps
- Thermal throttling potential under sustained load
- Display brightness data unavailable, potentially lower than A23
Samsung Galaxy A23 5G
- Brighter display (508 nits)
- More balanced performance with Snapdragon 695
- Samsung’s image processing expertise
- Slower 25W charging
- CPU performance slightly lower than A77
Display Comparison
The Samsung Galaxy A23 5G boasts a display capable of reaching 508 nits of peak brightness, a significant advantage for outdoor visibility compared to the Oppo A77 (brightness data unavailable). Both displays share a 1328:1 contrast ratio, suggesting similar levels of black depth and color vibrancy. While neither manufacturer specifies panel technology, the A23’s higher brightness suggests a potentially more advanced LCD panel. The lack of high refresh rate support on either device is typical for this price segment, but impacts smoothness during scrolling and animations.
Camera Comparison
Both the Oppo A77 and Samsung Galaxy A23 5G feature photo/video capabilities, but detailed sensor information is limited. Without specific megapixel counts or sensor sizes, a direct comparison is difficult. It’s reasonable to assume both phones include a primary camera, ultrawide, and potentially a depth or macro sensor. Given Samsung’s image processing expertise, the A23 5G is likely to deliver more consistently pleasing images, particularly in challenging lighting conditions. The inclusion of Optical Image Stabilization (OIS) on either device is unlikely at this price point.
Performance
The Oppo A77’s Mediatek Dimensity 810, built on a 6nm process, features a CPU configuration of 2x2.4 GHz Cortex-A76 cores and 6x2.0 GHz Cortex-A55 cores. This contrasts with the Samsung Galaxy A23 5G’s Qualcomm Snapdragon 695 5G (also 6nm) with its 2x2.2 GHz Kryo 660 Gold and 6x1.7 GHz Kryo 660 Silver cores. The Dimensity 810’s higher clock speeds on its performance cores translate to a theoretical advantage in CPU-bound tasks. However, the Snapdragon 695 often demonstrates better sustained performance due to Qualcomm’s more mature thermal management. The A77 will likely excel in short bursts of demanding activity, while the A23 will maintain consistent performance over longer periods.
Battery Life
Both devices share an endurance rating of 138 hours, indicating comparable battery life under typical usage scenarios. The Oppo A77 supports 33W wired charging, allowing it to reach 53% charge in 30 minutes. The Samsung Galaxy A23 5G is limited to 25W charging, resulting in a slower charging speed. While the A23’s battery capacity isn’t specified, the faster charging of the A77 provides a convenience advantage for users who frequently need to top up their battery quickly.
Buying Guide
Buy the Oppo A77 if you need a phone capable of handling more intensive applications and occasional gaming, and are willing to potentially trade off some battery optimization. Buy the Samsung Galaxy A23 5G if you prefer a consistently smooth experience for everyday tasks, value a slightly brighter display, and prioritize a balanced approach to performance and battery life. Both phones are excellent choices for budget-conscious 5G adopters.
