The Pros and Cons of the OPPO A6 Pro 4G

In the middle of the growing competition among mid-range phones, OPPO A6 Pro comes with a different approach. It doesn’t try to be the fastest, but instead focuses on durability and battery life.

This seems to be OPPO’s response to many users who want a phone with strong durability. OPPO noticed this need and launched OPPO A6 Pro 5G, priced at around US$ 250, along with its sibling, the OPPO A6 Pro 4G (or simply OPPO A6 Pro), sold at US$ 200. This article focuses on the 4G variant.

So, what is the OPPO A6 Pro really like? Is it worth considering? Let’s take a look at its pros and cons to see if this phone is a good choice in the price range.

Pros of OPPO A6 Pro

So, what are the pros of the OPPO A6 Pro? To find out, take a look at some of its key strengths below.

1. Equipped with IP66, IP68, IP69, and Military-Grade Durability

One of the main strengths of the OPPO A6 Pro is its outstanding durability. The phone comes with three certifications, IP66, IP68, and IP69.

This means it can handle high-pressure water spray from any direction (IP66 and IP69) and can survive being submerged in fresh water up to 1.5 meters deep for 30 minutes (IP68).

It also meets the Military-Grade Shock Resistance standard. With its impact-resistant body design, accidental drops from a table or pocket won’t cause serious damage.

According to OPPO, this toughness also comes with reliable long-term performance for up to 60 months, showing their focus on both hardware and software durability.

The phone also includes a one-click ejection feature that helps remove water or dust. On top of that, it’s protected by Crystal Shield Glass, which improves the screen’s resistance to scratches and daily wear.

2. Comes with a Bright AMOLED Screen

One of the nice things about this phone is its screen. The OPPO A6 Pro 4G comes with a 6.57-inch AMOLED panel with sharp FHD+ resolution and a 120 Hz refresh rate. I was quite surprised to see this, as the A series usually uses IPS panels.

With the AMOLED panel, the phone has a pleasant visual experience with smooth animations when scrolling through social media. The display is also able to show 1.07 billion colors and reach a peak brightness of up to 1400 nits, keeping it bright even under strong sunlight.

Its thin bezel design gives it a 93% screen-to-body ratio, creating an immersive and premium look. As mentioned in a review by Mas Tech on YouTube, the visuals feel similar to the Reno series, OPPO’s higher-end line.

The screen responsiveness is also impressive, with a 240 Hz touch sampling rate that makes navigation fast and accurate. On top of that, the phone can be used with wet or sweaty hands, which is a rare feature in this price range.

3. 7000 mAh Battery and 80W Charger

The 7000 mAh battery in the OPPO A6 Pro 4G is one of its biggest strengths. This capacity is much higher than most phones in its class. In 2025, most phones priced above US$ 120 only offer around 6000 mAh.

Even more impressive, the phone manages to keep a slim and light body despite the large battery, weighing only 185–188 grams and just 8 mm thick. This is possible because of its lighter silicon-carbon battery technology.

Besides the large battery, the OPPO A6 Pro also supports 80W SUPERVOOC fast charging. OPPO claims that it can reach 50% charge in just 30 minutes.

This claim seems true, as tests by the PhoneWorld YouTube channel showed the phone reaching 100% in about 61 minutes. That means it charged 50% in the first 30 minutes and the rest in the next 30 minutes.

Another useful feature is reverse charging with a cable. This lets the OPPO A6 Pro 4G act like a power bank to charge other devices such as earphones, mini speakers, or even other phones during an emergency.

4. SuperCool VC Cooling System

To keep performance optimal and prevent overheating, the OPPO A6 Pro 4G comes with the SuperCool VC (Vapor Chamber) cooling system. This system spreads heat quickly and efficiently to keep performance smooth and stable. As a result, the phone stays cool and comfortable even during long use.

The performance is also quite good. The phone runs on the MediaTek Helio G100 chipset, which is powerful enough for daily multitasking, social media, and popular games on medium settings. It also has 8 GB of RAM.

According to the PhoneWorld YouTube channel, the phone runs smoothly with minimal lag even during heavy use, including when using the camera. This means daily performance is solid and reliable.

The AI Game Boost feature helps enhance the gaming experience. With good cooling, long battery life, and balanced performance, the A6 Pro is ideal for users who want a reliable phone for everyday use.

5. 50 MP Camera with Underwater Photography Capability

On the back, the phone has a dual camera setup with a 50 MP main sensor (f/1.8) and a 2 MP depth sensor. In good lighting, it produces detailed photos with vivid colors.

The 50 MP camera delivers high-quality photos with sharp details, even when zoomed or cropped, and shows natural color tones. In low light, the results are fairly standard for its class.

The most interesting feature is its underwater photography capability. Since the phone has IP68 certification, it can be used underwater. This feature disables the touchscreen and switches the camera controls to the physical volume buttons to make it easier to take photos or videos in fresh water.

6. 16 MP Front Camera

OPPO A6 Pro has a 16 MP (f/2.4) front camera designed for clear and natural selfies. It captures faces sharply and shows pleasing skin tones. With this high resolution, photos stay detailed even after cropping. In good lighting, the dynamic range is balanced and consistent.

For videos, the front camera supports recording at up to 1080p 30fps, which is suitable for video calls, casual live streams, and short vlogs.

In low light, the AMOLED display acts as a natural light source, helping your face stay visible. When it’s too dark, the Screen Fill Light mode provides extra brightness. OPPO also includes several practical camera features for daily use and social media, such as:

• Portrait Mode: Creates a bokeh effect with clear background separation, perfect for profile photos.
• Night Mode: Improves brightness and reduces noise in dark scenes.
• Dual-view Video: Records with both front and rear cameras at the same time.
• Time-Lapse: Captures creative videos with time-lapse effects.

The front camera produces fine details both day and night, with natural-looking colors. For video calls or social media, it supports 1080p 30 fps recording.

7. 2-Year OS Warranty and Full Connectivity

The OPPO A6 Pro runs on ColorOS 15 (Android 15) that can give a smooth experience with smart features like Smart Sidebar and AI Eraser. OPPO promises two major Android updates and three years of security patches, keeping the phone updated and secure.

Connectivity supports AI LinkBoost 3.0, which uses AI to analyze Wi-Fi and cellular signals and switch to the most stable connection automatically. It also includes important connection features:

• Physical Connections: USB Type-C port with OTG support, allowing connection to external devices like flash drives.
• Wireless Connections: Dual-band Wi-Fi, efficient Bluetooth 5.4, and NFC for easy contactless payments.

OPPO A6 Pro Cons

Despite having many good features, the OPPO A6 Pro still has some drawbacks that should be considered. Here are the main ones.

1. Still 4G and Limited Performance

OPPO A6 Pro uses the MediaTek Helio G100, which is a 4G chip, so it only supports 4G LTE networks. This is quite disappointing because many phones in its price range already support 5G, such as the Infinix GT 30, iQOO Z10, and the Samsung Galaxy A17 5G, which costs almost the same.

Although the MediaTek Helio G100 is good enough for daily use and casual gaming, its performance feels weaker compared to other phones in the same price range.

This is something OPPO needs to improve to make the product more appealing. With an AnTuTu score between 540,000 and 580,000, the performance is decent but not great for users who focus on heavy gaming or multitasking.

2. No Ultrawide Camera

Like many other phones in its class, the OPPO A6 Pro does not include an ultrawide camera. This is a pity because the ultrawide lens is quite useful for taking wider photos.

3. Hybrid microSD Slot

This phone uses a hybrid SIM slot, which means users must choose between using two SIM cards or one SIM card and a microSD card. For those who need both, this can be limiting.

The OPPO A6 Pro also lacks an audio jack, so users will need to use TWS or wireless earphones instead of wired ones.

4. No Gyro Hardware

For gaming fans, this can be a deal-breaker. The OPPO A6 Pro 4G doesn't have a hardware gyroscope sensor and instead uses a software-based version. Because of this, games that need motion control, such as shooting in FPS games, may feel less accurate and less realistic.

Conclusion

OPPO A6 Pro focuses on durability, display quality, and battery life, which are strong points for its price range. However, there are some drawbacks, such as the lack of 5G support and the absence of an ultrawide camera.

If buyers don’t mind these limitations and prefer a phone with excellent endurance, the OPPO A6 Pro is still a good choice. But for those who want 5G connectivity, the OPPO A6 Pro 5G would be the better option.
