Samsung Galaxy S21+ vs Samsung Galaxy S23+
The Verdict
Both phones command the same $999 price point, but the Galaxy S23+ demonstrates meaningful generational improvements across key areas. Samsung's newer flagship boasts a significantly more powerful Snapdragon 8 Gen 2 processor with the Adreno 740 GPU, delivering noticeably faster performance than the S21+ Plus's Snapdragon 888. Camera capabilities lean toward the S23+, featuring a superior 50MP main sensor with Dual Pixel PDAF versus the S21+ Plus's 12MP sensor, though the S21+ Plus retains a slightly better telephoto at 3x hybrid zoom. Display brightness jumps substantially to 1750 nits on the S23+, compared to 1300 nits, ensuring better outdoor visibility. Charging speeds favor the S23+ at 45W versus 25W, while battery capacities are comparable. The S23+ includes Wi-Fi 6E and Bluetooth 5.3 for superior connectivity. However, the S21+ Plus offers a fractionally larger 6.7-inch display. For photography enthusiasts and those prioritizing performance, the S23+ justifies the purchase despite identical pricing.
