vivo Y30g
- Significantly faster processor (Dimensity 700)
- 5G connectivity for faster data speeds
- More efficient chipset for potentially better battery life
- Slower charging speed (10W)
- Likely a less feature-rich camera system
Oppo A55s
- Faster charging (18W)
- Potentially lower price point

Display Comparison
Neither device boasts a standout display. Given the context data focuses on processing, we can infer both likely utilize LCD panels common in this price bracket. The absence of specifications like resolution or refresh rate suggests a focus on cost optimization. Bezels are likely comparable, and color accuracy will be standard for budget devices. The real difference lies elsewhere.
Camera Comparison
Without detailed camera specifications, a direct comparison is difficult. However, it’s reasonable to assume both phones feature a primary camera and supporting lenses (likely a depth or macro sensor). The image processing capabilities of the Dimensity 700 in the A55s may offer slightly better image quality, particularly in low-light conditions, due to its more powerful ISP (Image Signal Processor). The Y30g’s Helio P65 ISP is less capable. We can expect similar performance from any included 2MP macro lenses on both devices – largely a marketing feature with limited practical benefit.
Performance
The core differentiator is the chipset. The Oppo A55s’ Mediatek Dimensity 700, built on a 7nm process, is a clear upgrade over the vivo Y30g’s 12nm Mediatek Helio P65. The Dimensity 700’s Cortex-A76 cores (2x2.2 GHz) offer significantly higher single-core performance than the Y30g’s Cortex-A75 cores (2x2.0 GHz). This translates to snappier app launches and a more responsive user interface. The 7nm process also contributes to better power efficiency, potentially offsetting the A55s’ lower charging wattage. The Dimensity 700 also includes an integrated 5G modem, a feature likely absent in the Y30g, offering future-proofing and faster data speeds where available.
Battery Life
The vivo Y30g’s 18W wired charging is a clear advantage over the Oppo A55s’ 10W charging. This means the Y30g will charge from 0-100% significantly faster. However, the Dimensity 700’s superior power efficiency in the A55s may partially mitigate the slower charging speed. Real-world battery life will depend on usage patterns, but the A55s’ more efficient chipset could result in comparable or even slightly better endurance despite the lower charging wattage.
Buying Guide
Buy the vivo Y30g if you prioritize charging speed and are primarily a casual user focused on basic tasks like calls, messaging, and light social media. The 18W charging will minimize downtime. Buy the Oppo A55s if you value performance and responsiveness, especially if you enjoy mobile gaming, streaming video, or frequently switch between applications. The Dimensity 700 offers a significantly more fluid experience.
Frequently Asked Questions
❓ Will the Oppo A55s handle demanding games like PUBG Mobile smoothly?
The Mediatek Dimensity 700 in the Oppo A55s is capable of running PUBG Mobile at medium settings with reasonable frame rates. While it won't deliver a flagship gaming experience, it provides a significantly smoother experience than the Helio P65 in the vivo Y30g, which may struggle with consistent performance even at lower settings.
❓ Is the 10W charging on the Oppo A55s a dealbreaker considering the vivo Y30g has 18W charging?
While 10W is slower, the Dimensity 700’s improved power efficiency in the Oppo A55s means you may not notice a huge difference in overall daily usage. The faster charging of the Y30g is most beneficial if you frequently need to top up your phone quickly throughout the day.
❓ Does the Oppo A55s support 5G networks, and will I see a noticeable speed difference?
Yes, the Dimensity 700 chipset includes an integrated 5G modem. If you live in an area with 5G coverage, you will experience significantly faster download and upload speeds compared to 4G networks, making streaming, browsing, and downloading content much quicker.
