Vivo Y51 Pro vs Oppo F33 Pro Specs, Prices & Choice

This article compares the Vivo Y51 Pro and the Oppo F33 Pro across specs, pricing, and real-world usability to help you decide which phone fits your needs. The short answer: choose the Vivo Y51 Pro if you want a larger battery and a more capable processor, while the Oppo F33 Pro is the better pick if you prioritize a lighter, more compact design and a slightly better selfie camera. Below we break down every major difference, explain how to interpret the specs, and answer common questions.

Background: Where These Phones Fit

The Vivo Y51 Pro was released in late 2020 as a mid-range device aimed at users who want a big screen and long battery life without paying flagship prices. The Oppo F33 Pro (also known as the Oppo F17 Pro in some markets) launched around the same time, targeting the same price bracket but with a stronger emphasis on camera features and a slimmer build. Both phones run Android with their respective custom skins—Vivo’s Funtouch OS and Oppo’s ColorOS—and both support 4G LTE (no 5G on either model).

These phones are often compared because they share similar storage configurations and price points, but their design philosophies differ. Vivo focuses on endurance and raw performance, while Oppo leans into aesthetics and camera versatility. Understanding these priorities is key to making the right choice.

Specs Comparison: Vivo Y51 Pro vs Oppo F33 Pro

Here is a side-by-side look at the most important specifications. Note that some regional variants may have slightly different specs, so always check the exact model sold in your country.

• Display: Vivo Y51 Pro has a 6.58-inch IPS LCD with 1080×2408 resolution (401 ppi). Oppo F33 Pro has a 6.43-inch AMOLED with 1080×2400 resolution (409 ppi). The Oppo’s AMOLED offers deeper blacks and better contrast, but the Vivo’s LCD is still sharp.
• Processor: Vivo uses the Qualcomm Snapdragon 675 (11nm, octa-core up to 2.0 GHz). Oppo uses the MediaTek Helio P95 (12nm, octa-core up to 2.2 GHz). In CPU-heavy tasks, the Snapdragon 675 generally edges out the Helio P95, but the P95 has a slightly stronger GPU for gaming.
• RAM and Storage: Both come with 8GB RAM and 128GB internal storage. Vivo supports microSD expansion up to 1TB; Oppo also supports microSD but only up to 256GB.
• Rear Cameras: Vivo Y51 Pro has a quad-camera setup: 48MP main (f/1.8), 8MP ultrawide (f/2.2), 2MP macro, and 2MP depth. Oppo F33 Pro also has quad cameras: 48MP main (f/1.7), 8MP ultrawide (f/2.2), 2MP macro, and 2MP depth. The Oppo’s main sensor has a slightly wider aperture, which helps in low light.
• Front Camera: Vivo has a 16MP selfie camera (f/2.0). Oppo has a 16MP selfie camera (f/2.4) plus a 2MP depth sensor for bokeh effects. The Oppo’s dual front cameras allow for better portrait shots.
• Battery: Vivo Y51 Pro packs a 5000mAh battery with 18W fast charging. Oppo F33 Pro has a 4015mAh battery with 30W VOOC fast charging. The Vivo lasts longer on a single charge, but the Oppo charges faster.
• Build and Weight: Vivo weighs about 190g and is 8.4mm thick. Oppo is significantly lighter at 164g and slimmer at 7.5mm, making it more comfortable for one-handed use.
• Connectivity: Both have dual SIM, 4G LTE, Wi-Fi 5, Bluetooth 5.0, and a USB-C port. Neither has a headphone jack, but both include a USB-C to 3.5mm adapter in the box.
• Operating System: Vivo ships with Funtouch OS 11 based on Android 11. Oppo ships with ColorOS 7.2 based on Android 10, but later received an update to Android 11. Both have received security patches, but Vivo’s update policy has been slightly more consistent.

Price Comparison and Value

Pricing varies by region and time, but at launch, the Vivo Y51 Pro was priced around $250–$300 USD, while the Oppo F33 Pro was slightly more expensive at $280–$330 USD. In many markets, the Oppo F33 Pro has dropped in price faster, so you may find it cheaper than the Vivo today. However, the Vivo often offers better value for money because of its larger battery and superior processor for everyday tasks.

When comparing prices, consider the total cost of ownership: the Oppo’s faster charging means you can top up quickly, but the Vivo’s bigger battery means you might not need to charge as often. If you find the Oppo at a significantly lower price, it becomes a more attractive option.

How to Choose: Which One Fits Your Needs?

Your choice should depend on what you value most. Here are the key decision factors:

• Battery life: If you are a heavy user who streams videos, plays games, or uses navigation frequently, the Vivo Y51 Pro’s 5000mAh battery will easily last a full day, sometimes two. The Oppo F33 Pro’s 4015mAh battery will likely need a mid-day top-up.
• Charging speed: If you have limited time to charge, the Oppo’s 30W VOOC charging is significantly faster—it can go from 0 to about 50% in 30 minutes. The Vivo’s 18W charging takes about 2 hours for a full charge.
• Display quality: The Oppo’s AMOLED screen offers better colors and true blacks, which is noticeable when watching movies or using dark mode. The Vivo’s LCD is still good, but it can’t match AMOLED contrast.
• Camera preferences: Both have similar rear camera specs, but the Oppo’s main sensor has a wider aperture (f/1.7 vs f/1.8), which lets in more light for better low-light shots. The Oppo also has a dual front camera for more detailed selfie portraits.
• Gaming performance: The Oppo’s Helio P95 has a slightly better GPU, so it may handle graphics-intensive games at slightly higher settings. However, the Vivo’s Snapdragon 675 is more efficient and may offer smoother sustained performance due to better thermal management.
• Build and portability: The Oppo is noticeably lighter and thinner, making it easier to carry and use with one hand. The Vivo is bulkier but feels more substantial.

Common Problems and Misconceptions

One common misconception is that the Oppo F33 Pro is a newer phone than the Vivo Y51 Pro because it has “Pro� in the name. In reality, both launched within months of each other, and the “Pro� suffix is just marketing. Another misconception is that the Oppo’s MediaTek processor is inferior—while it is less efficient, it performs comparably in daily use.

Users have reported that the Vivo Y51 Pro’s Funtouch OS can be heavy with pre-installed apps (bloatware), which slows down the phone over time. The Oppo’s ColorOS is generally cleaner, but it also has some ads in system apps. Both phones have been updated to Android 11, but neither is guaranteed to receive Android 12 or beyond. If long-term software updates are critical, you may want to consider a different brand.

Alternatives to Consider

If neither phone fully satisfies you, there are other options in the same price range:

• Xiaomi Redmi Note 10 Pro: Offers a 120Hz AMOLED display, a more powerful Snapdragon 732G processor, and a 5020mAh battery, often at a similar price.
• Realme 7 Pro: Has a 65W fast charging, a 90Hz AMOLED screen, and a Snapdragon 720G, making it a strong all-rounder.
• Samsung Galaxy M32: Features a 6000mAh battery and a Super AMOLED display, but its processor is weaker than both the Vivo and Oppo.
• Poco X3 Pro: If gaming is your priority, this phone offers a Snapdragon 860 and a 120Hz screen for a similar price.
