Tech review of Oppo A77

The Oppo A77 is a 2022 mid-range 5G phone built around practical essentials: a large screen, a 5,000 mAh battery, expandable storage and stereo speakers. Its Dimensity 810 gives it a stronger foundation for everyday use than many basic budget handsets of its time, but the HD-resolution display and modest camera setup show where Oppo kept costs down. It suits buyers who value connectivity and endurance over a premium screen or photography features.

Design & Display

At 190 g and 8 mm thick, the A77 is a fairly substantial but not unusually bulky phone. Its 6.56-inch IPS LCD offers plenty of room for browsing, messaging and video, while 720 × 1612 resolution is a noticeable compromise by 2022 standards: text and fine details will look less crisp than on Full HD screens. The 269-ppi density makes this a sensible everyday panel rather than one for users who prioritize sharpness. No display protection is specified, so a case and screen protector are prudent.

Performance & Storage

The Dimensity 810 is a capable mid-range 5G chip, with two performance-focused Cortex-A76 cores and six efficiency-oriented Cortex-A55 cores. It should handle routine apps, multitasking and casual games comfortably, though demanding games and heavy workloads are a less natural fit than on premium hardware. Compared with the 2021 Oppo A55’s entry-level Helio G35, the A77 represents a substantial step up in processing capability and adds 5G. Its 4 GB or 6 GB of RAM and 64 GB or 128 GB storage offer useful choice; a memory card slot provides room for photos and media without relying solely on internal capacity.

Cameras

The rear system pairs a 48 MP main camera with a 2 MP secondary camera, while the front camera is 8 MP. These figures describe resolution, not image quality: the specifications alone do not establish how well either camera performs in different lighting. Video recording tops out at 1080p at 30 fps on both front and rear cameras, so there is no listed 4K option or high-frame-rate capture. The A77’s main-camera resolution is similar to the 48 MP sensor in the older Oppo A9 (2020), but that comparison does not guarantee equivalent results.

Battery & Charging

A 5,000 mAh battery is a strong practical feature for a phone with an HD-resolution screen, and the capacity suggests a good basis for day-to-day endurance; actual runtime will depend on usage and network conditions. The Oppo A55 and A53 also use 5,000 mAh batteries, so this is a familiar strength in the A-series rather than a standout capacity advantage over those siblings. Charging details such as supported wattage are not provided, so charging speed cannot be assessed. USB-C is convenient, though the listed USB 2.0 interface is a basic data connection.

Connectivity & Practical Ownership

Broad 5G band support, dual SIM, dual-band Wi-Fi, Bluetooth 5.3 and multiple satellite-navigation systems make the A77 well equipped for everyday connectivity. Stereo speakers and a 3.5 mm headphone jack are welcome practical inclusions. The Nano SIM setup and card slot help accommodate separate work and personal lines alongside expandable storage. Repairability cannot be judged from the supplied specifications: there is no information about construction, parts availability or repair access. The listed software combination, Android 12 and ColorOS 14, is unusual for a 2022 launch, and the support period is not specified.

Verdict

👍 Pros:

• Capable mid-range Dimensity 810 processor with 5G
• Large 5,000 mAh battery
• Stereo speakers, headphone jack and expandable storage
• Dual SIM and broad connectivity options

👎 Cons:

• 720p display is less sharp than many 2022 alternatives
• Camera video is limited to 1080p at 30 fps
• Charging speed and software-support period are unspecified

The Oppo A77 makes the most sense for buyers seeking a practical 5G phone with useful everyday features and a large battery. Its display resolution and restrained camera capabilities are the clearest tradeoffs.
