Oppo A55

The Oppo A55, launched on October 1, 2021, positions itself in the medium-price range. It offers a blend of features aimed at budget-conscious consumers.

Build Quality The phone measures 163.6 mm in height, 75.7 mm in width, and 8.4 mm in depth, weighing 193 grams. Its construction is typical for its price bracket, offering a solid feel despite not utilizing premium materials. The side-mounted fingerprint sensor is a practical and common feature at this price point. The phone is available in Green, Starry Black, and Rainbow Blue color options.

Screen Quality The Oppo A55 features a 6.51-inch IPS LCD display with a resolution of 720 x 1600 pixels, resulting in a pixel density of 270 ppi. The screen has a typical brightness of 480 nits, with a peak brightness of 550 nits. While the screen is bright enough for indoor use, outdoor visibility may be compromised in bright sunlight. The display has a 20:9 aspect ratio and a contrast ratio of 1500:1. The lack of HDR support is expected at this price point. The screen is protected by a scratch-resistant 2.5D curved glass. The display includes a water drop notch design. The color gamut covers 70% of NTSC.

Camera Performance The Oppo A55 employs a triple camera setup on the rear. The primary camera is a 13MP shooter with an f/2.2 aperture. Additional rear cameras include a 2MP depth sensor (f/2.4) for portrait mode and a 2MP macro lens (f/2.4). The front-facing selfie camera has an 8MP sensor with an f/2.0 aperture. The main camera can record video at 1080p at 30fps. Key features include autofocus, digital image stabilization, LED flash, and a range of shooting modes such as panorama, HDR, and face detection. Slow-motion video recording is available at 120fps. The phone lacks optical image stabilization and 4K video recording capabilities.

Software Experience The Oppo A55 runs on Android 11, and the maximum software update remains unspecified. The user experience is fairly standard for the operating system, offering the usual features and customization options found within Android.

Battery Performance The device is powered by a 5000 mAh Li-Polymer battery. It supports 10W fast charging via a USB Type-C 2.0 port. This charging speed is basic, and users can expect a moderate time to fully recharge the battery. The battery is non-removable.

Connectivity The Oppo A55 supports Wi-Fi 802.11a/b/g/n/ac with dual-band capabilities, Wi-Fi Direct, and hotspot functionality. It includes Bluetooth 5.1 with A2DP, LE, aptX, LDAC, and SBC codecs. GPS, A-GPS, GLONASS, Beidou, QZSS, and Galileo are included for location services. The phone has dual SIM capability (Nano SIM + Nano SIM). It also includes NFC. The USB Type-C port supports OTG functionality, allowing the device to connect to other devices. Network band support includes 2G, 3G, and 4G LTE networks. 5G bands are also listed; however, it should be noted that some specifications elsewhere in the documentation specify a MediaTek Dimensity 700 chipset, which is not compatible with the specified 4G bands. This apparent inconsistency needs to be investigated.

Performance The Oppo A55 utilizes a Mediatek MT6765G Helio G35 (12 nm) chipset, paired with an Octa-core CPU (4x2.3 GHz Cortex-A53 & 4x1.8 GHz Cortex-A53) and a PowerVR GE8320 GPU. This combination positions it as an entry-level or lower-mid-range performer, suitable for daily tasks and light gaming but not demanding applications. While the specifications in the hardware details section list a MediaTek Dimensity 700, this is inconsistent with the original specifications, and there may be a mix-up between different versions of the same model.

Value for Money The Oppo A55 is positioned as a medium-priced phone. The listed price for the 4GB/128GB version is around $143.24. The phone offers a large battery and a reasonable display, but it lacks premium features such as a high refresh rate display, fast charging, or advanced camera capabilities. The value proposition will depend on the user's priorities.
