Oppo F29 Pro 5G VS Vivo Y31 Pro 5G

In terms of physical design, the Oppo F29 Pro 5G is notably more compact and lighter across every measurable dimension. At 180 g and 7.6 mm thick, it undercuts the Vivo Y31 Pro 5G's 208 g and 8.1 mm profile by a meaningful margin — a 28 g weight difference is something most users will feel during prolonged one-handed use or when carrying the phone in a pocket. The smaller overall volume (91.93 cm³ vs 102.41 cm³) reinforces that the F29 Pro is the more pocketable, ergonomically friendlier device of the two.

The most significant differentiator in this group, however, is water protection. The Oppo F29 Pro 5G carries an IP68 rating, which means it is certified for submersion in water — the manufacturer classifies it as fully waterproof. The Vivo Y31 Pro 5G, by contrast, holds an IP64 rating, offering only splash and dust resistance, and is categorized simply as water resistant. In practice, this is a substantial gap: IP68 gives real peace of mind against accidental drops in water, while IP64 only guards against light splashes and should never be submerged.

Neither phone features a rugged build or a foldable form factor, so those points are evenly matched. Overall, the Oppo F29 Pro 5G holds a clear advantage in this design group — it is lighter, slimmer, and offers meaningfully superior water protection, making it the better-built option for users who prioritize portability and durability.

The single most impactful differentiator here is panel technology. The Oppo F29 Pro 5G uses an OLED/AMOLED display, while the Vivo Y31 Pro 5G relies on an LCD IPS panel. This distinction carries real-world consequences: AMOLED delivers true blacks by switching off individual pixels, resulting in superior contrast, more vivid colors, and better visibility in direct sunlight. LCD panels, even good IPS ones, use a backlight that prevents true blacks and generally produce a flatter image. For media consumption, gaming, or any color-sensitive work, the AMOLED panel on the F29 Pro is a tangible upgrade in everyday visual experience.

Where the two phones converge is almost everywhere else. Screen sizes are virtually identical at 6.7″ vs 6.72″, pixel density is a statistical tie at 394 ppi vs 393 ppi, and both run at a smooth 120Hz refresh rate — meaning scrolling and animations feel equally fluid on both devices. Neither supports HDR10, HDR10+, or Dolby Vision, so premium streaming HDR formats are off the table for both.

One additional edge belongs to the F29 Pro: it supports an Always-On Display, which lets users glance at the time, notifications, or widgets without waking the screen — a convenience feature the Y31 Pro lacks entirely, and one that AMOLED makes power-efficient since only active pixels consume energy. Overall, the Oppo F29 Pro 5G has a clear display advantage, driven by its superior panel technology and the Always-On Display feature, despite the two phones being otherwise nearly identical in size, sharpness, and refresh rate.

Both phones are built on an identical silicon foundation: the MediaTek Dimensity 7300 chipset, manufactured on a 4 nm process with the same CPU configuration, GPU, clock speeds, and benchmark results. The Geekbench 6 scores — 1026 single-core and 2932 multi-core — are exactly the same for both devices, which is expected given that every processing component is shared. In day-to-day use, this means users can expect equivalent responsiveness, app launch speeds, and gaming performance from either phone.

The one meaningful difference within this group is RAM. The Oppo F29 Pro 5G ships with 12 GB, while the Vivo Y31 Pro 5G comes with 8 GB. Both use the same LPDDR5 memory running at 6400 MHz, so the speed is identical — but the capacity gap matters. More RAM allows the system to keep a larger number of apps active in the background simultaneously, reducing reload times when switching between tasks. For heavy multitaskers or users who run memory-intensive apps and games, the F29 Pro's extra headroom provides a practical advantage, even though both phones would handle everyday tasks comfortably.

On raw processing power, these two devices are a dead tie. The F29 Pro, however, earns a narrow overall edge in this group solely due to its higher RAM — a real-world benefit for sustained multitasking that the shared chipset specs cannot offset.

The rear camera systems on both phones start from the same baseline: a 50 MP + 2 MP dual-lens setup with identical apertures, phase-detection autofocus, and 4K at 30fps video recording. Manual controls — ISO, exposure, focus, white balance — are available on both as well. Where the F29 Pro separates itself is with built-in Optical Image Stabilization (OIS), a feature the Vivo Y31 Pro 5G lacks entirely. OIS physically compensates for hand movement during shooting, which makes a tangible difference when capturing handheld video or shooting in low light where slower shutter speeds are required. Without it, the Y31 Pro is more susceptible to motion blur and shakier footage.

Selfie shooters face an even starker contrast. The Oppo F29 Pro 5G packs a 16 MP front camera, doubling the Y31 Pro's 8 MP sensor. More megapixels on a front camera translates directly to sharper, more detailed selfies and better-quality video calls. The Y31 Pro does counter slightly with a wider front aperture of f/2.0 versus the F29 Pro's f/2.4, meaning it lets in more light per pixel — which can help in dim environments — but this advantage is modest compared to the resolution gap.

Taken together, the Oppo F29 Pro 5G holds a clear camera advantage. OIS is a meaningful real-world differentiator for video and low-light photography, and the front camera resolution gap is hard to ignore for users who prioritize selfies or video calling. The Y31 Pro's marginally brighter front aperture is a minor consolation that does not shift the overall balance.

This is a rare case of absolute parity. Both the Oppo F29 Pro 5G and the Vivo Y31 Pro 5G run Android 15 and share an identical feature set across every single data point in this group — from privacy controls like location and camera/microphone permissions, to productivity features like split-screen, Picture-in-Picture, and widget support. Even less common features such as on-device machine learning, offline voice recognition, dynamic theming, and the ability to offload unused apps are present on both devices without exception.

Notably, neither phone receives direct OS updates from Google — both rely on their respective manufacturers to push Android updates, which is standard practice for most Android OEMs. Users on either device will be equally dependent on Oppo and Vivo's update cadences, which is worth keeping in mind for long-term software support expectations. Equally, neither blocks cross-site tracking or supports Wi-Fi password sharing, so those omissions apply to both.

There is simply no differentiator to declare here. This group is a complete tie — every supported feature and every missing feature is shared identically between the two phones. A buyer's operating system experience will be functionally indistinguishable regardless of which device they choose, with differences in software experience coming only from each brand's custom Android skin rather than from anything captured in this spec set.

Battery life and charging speed pull in opposite directions here, making this a classic capacity-versus-replenishment trade-off. The Vivo Y31 Pro 5G carries a larger 6500 mAh battery compared to the Oppo F29 Pro 5G's 6000 mAh — a 500 mAh difference that, while not dramatic, could translate to an extra 30–60 minutes of screen-on time under typical usage, giving the Y31 Pro a modest but real endurance edge for users who stretch their phone through long days without access to a charger.

The F29 Pro fights back decisively on charging speed. Its 80W fast charging nearly doubles the Y31 Pro's 44W, meaning the F29 Pro can replenish its battery in roughly half the time. For users who charge opportunistically — during a commute, a lunch break, or between meetings — this is a highly practical advantage. A quick 20-minute top-up on the F29 Pro will deliver significantly more charge than the same session on the Y31 Pro. Both phones come bundled with a charger and support fast charging, so neither requires an additional purchase to access these speeds.

Neither phone offers wireless charging, so that is a shared limitation. Overall, this group is a genuine trade-off with no outright winner: the Y31 Pro suits users who prioritize raw endurance and want to charge less frequently, while the F29 Pro is the better fit for those who charge regularly and value getting back to full power as quickly as possible.

Both phones share the same foundational audio setup — stereo speakers, no 3.5 mm headphone jack, and no FM radio — so wired headphone users will need an adapter or Bluetooth earphones on either device. The speaker experience is equally matched on paper, leaving wireless audio quality as the only meaningful battleground in this group.

That is where the Oppo F29 Pro 5G pulls ahead. It supports both aptX and aptX HD, two Qualcomm Bluetooth audio codecs that enable higher-quality wireless audio transmission when paired with compatible headphones. aptX reduces the compression artifacts common in standard Bluetooth audio, while aptX HD goes further, supporting higher bit-depth and sampling rates for near-lossless wireless sound. The Vivo Y31 Pro 5G supports neither, meaning it is limited to standard Bluetooth audio codecs, which deliver noticeably lower fidelity to audiophile-grade wireless headphones that could otherwise take advantage of the enhanced codecs.

For casual listeners using budget Bluetooth earbuds, this distinction may go unnoticed in daily use. But for users who own aptX or aptX HD-compatible headphones and care about wireless audio quality, the Oppo F29 Pro 5G has a clear advantage — it is simply capable of a higher-quality wireless listening experience that the Y31 Pro cannot match.

Across the broad sweep of connectivity features, these two phones are well-matched — both offer 5G, dual SIM, USB Type-C, Bluetooth 5.4, GPS with Galileo support, an infrared sensor, and identical peak download and upload speeds of 3270 Mbits/s. The shared sensor suite (gyroscope, accelerometer, compass) is also equivalent. The meaningful differences, however, are concentrated in three specific areas.

The Oppo F29 Pro 5G supports Wi-Fi 6 (802.11ax), while the Vivo Y31 Pro 5G tops out at Wi-Fi 5 (802.11ac). Wi-Fi 6 delivers better throughput in congested environments — like offices or apartments with many connected devices — and offers improved efficiency. The F29 Pro also includes NFC, which the Y31 Pro entirely lacks; NFC is essential for contactless payments and quick device pairing, making its absence a notable gap for users who rely on mobile payment platforms. On the flip side, the Y31 Pro counters with an external memory slot, allowing users to expand storage via a microSD card — a flexibility the F29 Pro does not offer since it lacks such a slot.

Weighing these trade-offs, the Oppo F29 Pro 5G holds the broader connectivity advantage. Wi-Fi 6 and NFC are features with growing everyday relevance, whereas the expandable storage on the Y31 Pro, while useful, is a more situational benefit — particularly since both phones already ship with 256 GB of internal storage.

The miscellaneous spec group offers very little to separate these two devices. Both the Oppo F29 Pro 5G and the Vivo Y31 Pro 5G share identical attributes across every data point here — each has a video light, and neither features a sapphire glass display, a curved display, or an e-paper display.

This is a complete tie with no differentiators to analyze. The shared absence of premium extras like sapphire glass is typical at this market segment, and the presence of a video light on both phones is a minor but equal convenience for recording video in low-light conditions. No buying decision should be influenced by this group either way.
