OPPO A78 5G: In today’s rapidly evolving smartphone landscape, finding a device that offers 5G connectivity without breaking the bank can be challenging.
The OPPO A78 5G emerges as a compelling contender in this space, combining essential features with next-generation connectivity at a price point that makes 5G accessible to more users.
This mid-range offering from the Chinese tech giant has garnered attention for striking a balance between performance and affordability while maintaining the sleek design language OPPO has become known for.
OPPO A78 5G: Design and Build Quality
The OPPO A78 5G features a refreshingly modern design that belies its mid-range classification. With dimensions of 163.8 x 75.1 x 7.99mm and weighing approximately 188g, the device strikes an excellent balance between screen real estate and ergonomics.
The phone sports a plastic frame with a glass front, while the back panel features a glossy finish that OPPO calls “Glowing Design.” This unique finish creates subtle light patterns when viewed from different angles.
Available in two striking colorways—Glowing Black and Glowing Blue—the A78 5G offers aesthetic appeal rarely found at this price point.
The phone also boasts an IPX4 rating, providing basic protection against water splashes, though not full water immersion.
The right edge houses the power button, which doubles as a fingerprint scanner, while the volume rocker sits on the left.
At the bottom, you’ll find the USB-C port, speaker grille, and the increasingly rare 3.5mm headphone jack—a welcome inclusion for those who prefer wired audio solutions.
Display Technology
Dominating the front of the device is a 6.56-inch LCD display with a waterdrop notch housing the front camera.
While not an AMOLED panel, the IPS LCD offers respectable performance with a 90Hz refresh rate that ensures smooth scrolling and animation transitions.
The 1612 x 720 resolution (HD+) may not match the sharpness of higher-end phones, but it remains perfectly adequate for everyday use and helps conserve battery life.
The display achieves a peak brightness of 480 nits, making it usable in most lighting conditions, though direct sunlight can pose challenges.
OPPO has included eye comfort features like AI Smart Backlight and Blue Light Filter to reduce eye strain during extended usage periods.
Performance and Hardware
Under the hood, the OPPO A78 5G is powered by the MediaTek Dimensity 700 chipset, an octa-core processor built on a 7nm process.
This includes two Cortex-A76 performance cores clocked at 2.2GHz and six Cortex-A55 efficiency cores running at 2.0GHz. While not the most powerful SoC in MediaTek’s lineup, it delivers balanced performance for day-to-day tasks.
The chipset is paired with 8GB of RAM and 128GB of internal storage, expandable via microSD card up to 1TB.
OPPO has also implemented RAM expansion technology, which can convert up to 8GB of storage into virtual RAM, potentially allowing for better multitasking performance.
Graphics are handled by the integrated Mali-G57 MC2 GPU, which provides adequate performance for casual gaming.
While demanding titles may require reduced graphics settings, popular games like PUBG Mobile and Call of Duty Mobile run smoothly at medium settings.
Camera System
Photography on the OPPO A78 5G is managed by a dual-camera setup on the rear. The primary sensor is a 50MP shooter with f/1.8 aperture, capable of capturing detailed images in good lighting conditions.
It’s accompanied by a 2MP depth sensor that assists with portrait mode shots.
The camera app comes with AI scene recognition, which can identify up to 16 different scenarios and adjust settings accordingly. Night mode is also present, though results are modest compared to flagship offerings.
Video recording tops out at 1080p at 30fps, which, while not groundbreaking, delivers stable footage for casual recording.
On the front, an 8MP selfie camera handles self-portraits and video calls competently. Beauty mode options are plentiful, as expected from OPPO devices, allowing users to customize their look according to preference.
Battery Life and Charging
One of the standout features of the A78 5G is its robust 5000mAh battery, which easily provides a full day of usage even with moderate 5G connectivity. OPPO claims up to 24 hours of talk time or 16 hours of video playback on a single charge.
When it’s time to recharge, the included 33W SuperVOOC fast charger can replenish the battery from empty to 50% in approximately 30 minutes, with a full charge taking around 75 minutes.
While not as rapid as some premium offerings, this charging speed represents excellent value in the mid-range segment.
The device also includes various power-saving modes and optimization features that can extend battery life when needed, such as Super Power Saving Mode and Night Standby Mode.
Software Experience
The OPPO A78 5G runs ColorOS 13.1 based on Android 13, offering a feature-rich interface with extensive customization options.
ColorOS has matured significantly over the years, now offering a cleaner experience while maintaining useful additions like Game Space, Clone Apps, and Private Safe.
OPPO promises two years of Android version updates and three years of security patches for the A78 5G, which provides reasonable longevity for a mid-range device.
The interface is generally fluid thanks to the 90Hz refresh rate, though occasional stutters may appear in heavy multitasking scenarios.
Connectivity and Additional Features
As the name suggests, 5G connectivity is the headline feature of this device. The A78 5G supports multiple 5G bands, ensuring compatibility with most carriers worldwide.
Other connectivity options include dual-band Wi-Fi, Bluetooth 5.3, GPS, and NFC for contactless payments.
Audio output through the single bottom-firing speaker is adequately loud, though lacking in bass response.
The inclusion of a 3.5mm headphone jack provides flexibility for audio connections, while Dirac-tuned audio enhancement improves the listening experience with headphones.
Value Proposition
Priced competitively in the mid-range segment, the OPPO A78 5G represents excellent value for consumers looking to enter the 5G ecosystem without significant investment.
While compromises have been made in areas like display resolution and processing power, the device excels in battery life, charging speed, and overall user experience.
