Editorial report

Oppo A55 technical sheet

The Oppo A55 suits buyers looking for a large display and a 120 Hz refresh rate; the trade-off is its 270 ppi density, lower than that of most phones of its time. The 6.51-inch display also has a resolution of 720 × 1600 px. Its refresh rate is higher than that of most phones launched around the same time, while the pixel density is a clear limitation for anyone prioritizing a sharper image.

Performance is the main weakness: its 4 GB of RAM and AnTuTu score of 110,000 are lower than those of most phones of its time. This version pairs 4 GB of RAM with 128 GB of expandable storage; the Oppo A55 is also sold with 64 GB. The 50 MP rear camera records video at 1080p and 30 fps, but it has no optical image stabilization. The 5,000 mAh battery supports 18 W charging; both figures are typical for phones of its time.

Other features include dual SIM, NFC, a 3.5 mm audio jack, and Android 11. The large, high-refresh-rate display makes it a fit for buyers who place those features ahead of pixel density and performance. Its overall NeoScore is 4.6: a basic phone whose clearest distinction among phones launched around the same time is its display refresh rate.
