The Oppo A3 (China) and vivo Y71t represent compelling options in the increasingly competitive sub-$250 5G smartphone market. While both aim to deliver a connected experience without breaking the bank, they diverge in their core processing power and charging strategies. This comparison dives deep into the specifics to determine which device offers the best balance of performance, features, and value.
🏆 Quick Verdict
For the average user prioritizing consistent performance and slightly faster charging, the vivo Y71t emerges as the stronger choice. Its Dimensity 810 chipset offers a noticeable CPU performance advantage over the Snapdragon 695 in the Oppo A3, making it better suited for multitasking and demanding applications. However, the Oppo A3's reverse wired charging is a unique benefit.

Display Comparison
Neither Oppo nor vivo provide display specifications beyond the basic resolution. Given the price point, both likely utilize LCD panels. The real differentiator will be color calibration and brightness, which are currently unknown. However, the focus here is on internal components, and display quality is unlikely to be a major deciding factor for most buyers in this segment. Expect standard 60Hz refresh rates on both.
Camera Comparison
Without detailed camera specs, a direct comparison is difficult. Both phones likely feature a primary camera and depth sensor, with the Y71t potentially having a slight edge due to MediaTek’s image signal processor (ISP) capabilities. The Oppo A3’s camera performance will rely heavily on Qualcomm’s ISP, but the Dimensity 810’s ISP generally offers more advanced features like better noise reduction and dynamic range. The presence of OIS (Optical Image Stabilization) is unlikely on either device at this price point. Any 2MP macro or depth sensors are likely to offer minimal real-world benefit.
Performance
The core battleground is the chipset. The vivo Y71t’s MediaTek Dimensity 810, built on a 6nm process, features a more powerful CPU configuration with 2x2.4 GHz Cortex-A76 cores compared to the Oppo A3’s Snapdragon 695’s 2x2.2 GHz Kryo 660 Gold cores. This translates to a tangible performance advantage for the Y71t in CPU-intensive tasks. While both chips are 6nm, the Cortex-A76 architecture in the Dimensity 810 is generally more efficient and capable than the Kryo 660 Gold. The Snapdragon 695 benefits from Qualcomm’s integrated 5G modem, but the Dimensity 810’s 5G capabilities are equally robust. Gaming performance will favor the Y71t due to the stronger CPU and potentially more optimized GPU drivers.
Battery Life
Both devices offer fast charging, with the vivo Y71t at 44W claiming 70% charge in 33 minutes, and the Oppo A3 at 45W reaching 50% in 30 minutes. While the Oppo A3 has slightly higher wattage, the Y71t’s faster initial charging rate suggests more efficient power delivery. Battery capacity is not specified, but both are likely in the 5000mAh range. The Oppo A3’s inclusion of reverse wired charging is a significant advantage, allowing it to function as a power bank for other devices – a feature absent on the Y71t.
Buying Guide
Buy the Oppo A3 (China) if you need reverse wired charging to top up accessories like earbuds or smartwatches, and prioritize a brand known for its ColorOS software experience. Buy the vivo Y71t if you prefer a more powerful processor for smoother app switching and gaming, and value a slightly faster charging cycle for getting back up and running quickly.
Frequently Asked Questions
❓ Will the Dimensity 810 in the vivo Y71t get noticeably hotter during extended gaming sessions compared to the Snapdragon 695?
While both chips are 6nm, the Dimensity 810's higher performance ceiling means it *could* generate more heat under sustained load. However, thermal management depends heavily on the phone's cooling system, which is unknown for both devices. Expect some throttling during prolonged gaming on both, but the Y71t might experience it slightly sooner.
❓ Does the Oppo A3's reverse wired charging work with all types of earbuds and smartwatches?
The Oppo A3's reverse wired charging supports standard charging protocols like USB Power Delivery (PD). It should work with most earbuds and smartwatches that charge via USB-C, but charging speeds may vary depending on the accessory's power requirements. It won't fast charge devices that don't support PD.
❓ Is the difference in CPU performance between the Snapdragon 695 and Dimensity 810 noticeable in everyday tasks like browsing and social media?
For basic tasks like browsing and social media, the difference will be minimal. However, when multitasking with several apps open or running more demanding applications, the Dimensity 810's more powerful CPU will provide a smoother and more responsive experience.
