Realme P4 Pro 5G VS Vivo T4 Pro (128GB / 8GB RAM)

In terms of physical footprint, the Realme P4 Pro 5G and Vivo T4 Pro are remarkably close. The Realme measures 162.3 × 76.2 × 7.7 mm and weighs 189 g, while the Vivo is marginally taller and wider at 163.5 × 77 mm, slightly slimmer at 7.5 mm, and a touch heavier at 192 g. The 3 g weight difference and 0.2 mm thickness gap are imperceptible in daily use, meaning neither phone has a meaningful ergonomic advantage over the other. Both are non-foldable and lack a rugged build, so they occupy the same mainstream-slab category.

The most consequential difference in this group is water protection. The Realme P4 Pro holds an IP66 rating, which certifies resistance to powerful water jets but does not cover submersion. The Vivo T4 Pro steps up to IP68, a full waterproofing standard that protects against continuous immersion in water. In practical terms, IP66 handles rain, splashes, and accidental spills with confidence, but a drop into a sink or pool is a real risk. IP68 removes that anxiety entirely, making the Vivo the safer choice for anyone who frequently uses their phone near water or in unpredictable environments.

Overall, the Vivo T4 Pro holds a clear edge in this design group. Its IP68 certification is a meaningful, real-world upgrade over the Realme's IP66, and this advantage comes without any notable trade-off in size or weight. For users who prioritize durability and peace of mind around liquids, the Vivo wins this category outright.

Both phones share the same panel technology — OLED/AMOLED — and support HDR10+, so baseline color accuracy, contrast, and media compatibility are on equal footing. The meaningful gaps emerge in resolution and refresh rate. The Realme P4 Pro runs at 1280 × 2800 px with a pixel density of 453 ppi, while the Vivo T4 Pro tops out at 1080 × 2392 px at 388 ppi. That 65 ppi difference is perceptible: text and fine details will appear noticeably crisper on the Realme, which matters most when reading small print, viewing high-resolution photos, or using the phone at close range.

The refresh rate gap reinforces the Realme's display lead. Its 144Hz panel delivers smoother scrolling and more responsive gaming compared to the Vivo's 120Hz screen. In practice, the jump from 120Hz to 144Hz is subtler than going from 60Hz to 120Hz, but it is still a tangible advantage in fast-paced gaming and everyday swipe interactions. Adding to this, the Realme supports Always-On Display, a convenient feature for glancing at notifications and time without waking the screen fully — a capability the Vivo T4 Pro lacks entirely.

The Realme P4 Pro 5G holds a clear advantage in this category. Its higher resolution, sharper pixel density, faster refresh rate, and Always-On Display support combine to make it the stronger display package. The Vivo T4 Pro's screen is by no means poor — its OLED panel and HDR10+ support ensure solid visuals — but for display-conscious buyers, the Realme is the better choice here.

At the core, these two phones are identical: both are powered by the Qualcomm Snapdragon 7 Gen 4 on a 4 nm process, with the same CPU configuration, 1000 MHz GPU clock, 4200 MHz LPDDR5 memory speed, and a 6W TDP. This means raw processing performance, thermal behavior, and graphics capability will be virtually indistinguishable in real-world use. Tasks like app loading, gaming frame rates, and AI workloads will feel identical on both devices.

The differentiators here are entirely about capacity, not horsepower. The Realme P4 Pro ships with 12GB of RAM and 512GB of storage, while the Vivo T4 Pro offers 8GB of RAM and just 128GB of storage. The RAM gap is practically significant: more RAM means the system can keep a larger number of apps resident in the background, reducing reload times when multitasking. The storage gap is even starker — 512GB versus 128GB means the Realme can hold roughly four times as much content locally, which matters for users with large photo libraries, offline media, or many installed games.

Since the underlying silicon is identical, the Realme P4 Pro 5G wins this category purely on configuration. It offers more headroom for multitasking and substantially more room for data, with no performance trade-off whatsoever. For users who push their phones hard or simply dislike managing storage, the Realme is the stronger performer in practical terms.

The rear camera systems diverge meaningfully here. The Realme P4 Pro pairs a 50MP primary lens with a modest 2MP depth sensor, while the Vivo T4 Pro fields a proper triple-camera array: a 50MP main, a second 50MP lens, and a 2MP sensor. More importantly, the Vivo backs this up with 3x optical zoom — a capability the Realme entirely lacks. Optical zoom preserves image quality at distance in a way that digital crop cannot, making the Vivo a significantly more versatile shooter for travel, events, or any scenario where subjects are not within arm's reach. The Vivo's main sensor also carries a wider f/1.8 aperture compared to the Realme's f/2.2, which translates to better light intake in dim conditions.

The Realme fights back in two specific areas. Its main camera records video at 4K 60fps, versus the Vivo's ceiling of 4K 30fps — a tangible advantage for anyone shooting action footage or content that benefits from higher frame rates. On the selfie side, the Realme's 50MP front camera outresolves the Vivo's 32MP sensor, which will appeal to users for whom self-portrait detail is a priority.

Weighing the trade-offs, the Vivo T4 Pro holds the stronger overall camera position. Optical zoom and a triple-lens system offer day-to-day shooting versatility that a higher selfie resolution or 60fps video capability cannot fully offset for most users. The Realme is the better pick for video creators and selfie-focused users specifically, but for general photography flexibility, the Vivo has the clear edge.

This is a rare case of a complete specification tie. Both the Realme P4 Pro 5G and the Vivo T4 Pro run Android 15 and share an identical feature set across every 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, to quality-of-life additions like dynamic theming, extra dim mode, and battery health checks. There is no differentiator to analyze here because none exists in the provided data.

It is worth noting what both phones share as a baseline: a solid, modern Android 15 experience with strong privacy tooling and broad usability features. The absence of direct OS updates on both devices means neither will receive Android version upgrades straight from Google, relying instead on their respective manufacturers for software support — a shared limitation rather than an individual weakness.

For this specification group, the verdict is a dead tie. A buyer choosing between these two phones will find no software or OS-level reason to favor one over the other based on the available data. The decision should rest entirely on the advantages identified in other categories.

Battery capacity is where the Realme P4 Pro makes one of its strongest statements. Its 7000 mAh cell is notably large, outpacing the Vivo T4 Pro's already-generous 6500 mAh by 500 mAh. While real-world screen-on time depends on software and display factors analyzed elsewhere, a larger cell is a direct input to longevity — all else being equal, the Realme has more raw energy to draw from, which should translate to longer intervals between charges for heavy users.

The Vivo T4 Pro answers with a marginal but real edge in replenishment speed: its 90W fast charging nudges ahead of the Realme's 80W. The practical gap is modest — at these wattages, both phones are capable of very rapid top-ups, and the 10W difference may amount to only a few minutes over a full charge cycle. Neither phone supports wireless charging or reverse wireless charging, so both are strictly wired in their charging options.

On balance, the Realme P4 Pro 5G holds the advantage in this category. A 500 mAh capacity lead is meaningful for endurance-focused users, and the 10W charging speed deficit to the Vivo is too small to offset it. Buyers who prioritize going longer between charges will find the Realme the more compelling option here.

Wired listening is off the table for both phones — neither carries a 3.5mm headphone jack — and both deliver stereo speakers for on-device playback. That shared foundation means casual listeners will have a comparable experience. The real split emerges the moment wireless headphones enter the picture.

The Realme P4 Pro supports both aptX and LDAC, two of the most significant high-resolution Bluetooth audio codecs available on Android. LDAC in particular can transmit audio at up to three times the bitrate of standard SBC, making it the codec of choice for audiophiles pairing their phone with high-quality wireless headphones. The Vivo T4 Pro supports neither, meaning it will fall back to baseline codecs when paired with even premium headphones — a tangible quality ceiling for discerning listeners.

The Realme P4 Pro 5G wins this category without contest. Its LDAC and aptX support are meaningful, real-world advantages for anyone who invests in quality wireless audio gear. The Vivo T4 Pro has no compensating audio feature in the provided data, making this one of the cleaner edges in the entire comparison.

Across the broad sweep of connectivity specs, these two phones are nearly identical. Both support 5G, Wi-Fi 6, Bluetooth 5.4, NFC, and dual SIM — a well-rounded modern foundation. USB Type-C is present on both, though both are capped at USB 2.0 speeds, meaning neither is suited for fast wired data transfers or video output. Sensors are also evenly matched, with gyroscope, accelerometer, GPS, compass, and Galileo support shared across both devices.

The sole differentiator in this entire group is the Vivo T4 Pro's infrared sensor, which the Realme P4 Pro lacks. An IR blaster lets the phone function as a universal remote control for TVs, air conditioners, and other home appliances — a niche but genuinely useful feature for users who want to consolidate their remotes into a single device. It adds no complexity and costs nothing in daily use, making it a straightforward bonus.

This category is nearly a tie, but the Vivo T4 Pro takes a narrow edge solely on the strength of its infrared sensor. For users who have no interest in IR functionality, the two phones are effectively equal here. For those who do, the Vivo is the only option on the table.

The Miscellaneous group offers nothing to separate these two phones. Every data point — presence of a video light, absence of sapphire glass, flat display, and no e-paper panel — is identical across both the Realme P4 Pro 5G and the Vivo T4 Pro. There are no differentiators to analyze and no advantages to assign.

This is a complete tie, and buyers should weight this category at zero when making their decision. Any meaningful distinction between these two devices must be drawn from the other specification groups covered in this comparison.
