๐Ÿ“ฑ Design & Build: Sleek and Comfortable

The OPPO A78 5G features a slim 7.99mm profile with a matte textured back that resists fingerprints and smudges. Weighing just 188g, the phone feels comfortable in hand and pocket.

Itโ€™s available in two stylish shades:

  • Glowing Blue โ€“ With a shimmering effect under light
  • Glowing Black โ€“ Subtle, premium matte finish

The camera module is cleanly embedded and the edges are slightly curved, giving it a modern, premium appeal despite its budget pricing.


๐ŸŒˆ Display: Smooth, But Basic Resolution

The OPPO A78 5G sports a 6.56-inch IPS LCD panel with HD+ resolution (1612 x 720 pixels) and a 90Hz refresh rate.

What Youโ€™ll Like:

  • Smooth scrolling and animation due to 90Hz
  • Eye Comfort and AI backlight adjustment
  • Decent brightness under indoor conditions

Limitations:

  • Not Full HD+
  • Outdoor visibility is average under strong sunlight
  • No AMOLED panel (understandable at this price point)

For binge-watchers, the lack of FHD+ might feel like a compromise, but for everyday use โ€” browsing, social media, YouTube โ€” the display performs quite well.


๐Ÿš€ Performance: Reliable for Daily Use

Powered by the MediaTek Dimensity 700 chipset, the OPPO A78 5G offers reliable performance for basic multitasking, social media, video calls, and light gaming.

Paired with 8GB LPDDR4X RAM and 128GB UFS 2.2 storage, performance feels snappy for regular apps. It also supports RAM expansion up to 16GB, using virtual RAM for smoother background performance.

Gaming:

You can comfortably play games like:

  • Call of Duty: Mobile โ€“ Medium settings, stable performance
  • Free Fire โ€“ Smooth gameplay
  • BGMI / PUBG โ€“ Balanced graphics, minor heating after long play sessions

This phone is not meant for high-end gaming but gets the job done for casual players.


๐Ÿ“ธ Camera: Good in Daylight, Average at Night

The OPPO A78 5G offers a dual-camera setup:

  • 50MP main sensor (f/1.8)
  • 2MP depth sensor

The rear camera captures sharp images in daylight, with decent color accuracy and contrast. Portrait mode works well in good lighting, blurring backgrounds effectively.

Pros:

  • Good detailing in well-lit shots
  • Color consistency in natural light
  • AI scene enhancement improves contrast

Cons:

  • Low-light images lack sharpness
  • No ultra-wide or macro lens
  • Night Mode is basic

The 8MP front camera is adequate for selfies and video calls. Beauty filters are available, though heavy processing is noticeable in some scenarios.


๐Ÿ”‹ Battery Life: Long-Lasting & Fast-Charging

With a 5000mAh battery, the OPPO A78 5G easily lasts a full day and more on moderate usage. If you’re using it for social media, music, browsing, and some gaming, you can expect 1.5 days of backup.

Even if you’re a power user, the included 33W SuperVOOC charger takes the battery from 0 to 50% in about 28 minutes, and full charge in under 70 minutes.

This is a huge advantage at this price point, where fast charging is often limited or absent.
