Realme P4 Pro 5G (256GB / 8GB RAM) VS Vivo T4 Pro

In terms of physical dimensions, the two phones are nearly identical twins. The Realme P4 Pro comes in at 162.3 × 76.2 × 7.7 mm and 189 g, while the Vivo T4 Pro measures 163.5 × 77 × 7.5 mm and 192 g. The 3 g weight difference and 0.2 mm thickness gap are imperceptible in daily handling, and both devices occupy virtually the same volume. Neither has a rugged build or a foldable form factor, so for most users these physical dimensions will be a wash.

Where a meaningful distinction does emerge is in water protection. The Realme P4 Pro carries an IP66 rating, which certifies resistance against powerful water jets but does not cover submersion. The Vivo T4 Pro steps up to IP68, the higher standard that certifies protection against prolonged immersion in water. In real-world terms, IP66 is sufficient for rain, splashes, and accidental sink drops, but if the phone ends up fully submerged — in a pool, puddle, or toilet — IP68 provides a meaningful safety net that IP66 does not.

On balance, the two phones are essentially tied on form factor, but the Vivo T4 Pro holds a clear edge in water protection. For users who frequently expose their phone to wet environments or simply want greater peace of mind, the IP68 rating is a tangible and practical advantage over the Realme P4 Pro's IP66.

Both phones use OLED/AMOLED panels with HDR10+ support and branded damage-resistant glass, so the baseline display quality is strong on either device. The more telling differences lie in resolution and refresh rate. The Realme P4 Pro's 1280 × 2800 resolution at 6.8″ yields a pixel density of 453 ppi, while the Vivo T4 Pro's 1080 × 2392 panel across a 6.77″ screen lands at 388 ppi. That 65 ppi gap is genuinely perceptible — text appears crisper and fine detail in photos renders more clearly on the Realme, whereas the Vivo's 1080p output, while perfectly adequate for casual use, will show slight softness under close inspection.

The refresh rate gap — 144 Hz on the Realme versus 120 Hz on the Vivo — is a subtler distinction. Both rates deliver smooth scrolling well beyond what most users will consciously notice, but competitive mobile gamers may appreciate the extra headroom that 144 Hz provides. More practically impactful is the Realme's Always-On Display support, a feature absent on the Vivo T4 Pro. For users who rely on at-a-glance time, notification, and calendar information without waking the screen, this is a genuine convenience advantage in everyday use.

The Realme P4 Pro takes a clear overall edge in this category. Its higher pixel density, faster refresh rate, and Always-On Display capability collectively make it the stronger display package — particularly for users who prioritize visual sharpness and screen utility over raw size.

At the core, these two phones are effectively identical in processing hardware. Both run on the Qualcomm Snapdragon 7 Gen 4, built on a 4 nm process, with the same CPU configuration, 1000 MHz GPU clock, 4200 MHz LPDDR5 RAM speed, and a 6W TDP. Every meaningful benchmark — raw CPU throughput, graphics rendering, memory bandwidth at 33.6 GB/s — will come out virtually identical between the two devices. Choosing one over the other on the basis of the chipset alone would be pointless.

The sole differentiator in this category is RAM capacity. The Vivo T4 Pro ships with 12 GB, versus 8 GB on the Realme P4 Pro. This matters more than it might initially seem: RAM does not affect peak performance, but it directly impacts how many apps the system can hold in the background simultaneously. With 12 GB, the Vivo is less likely to reload apps from scratch when switching between several memory-intensive tasks, which translates to a smoother multitasking experience over extended use sessions. Heavy users who juggle multiple apps, games, and browser tabs will feel this difference more acutely than light users.

Given the fully identical chipset, the Vivo T4 Pro holds a narrow but real advantage here purely on the strength of its larger RAM allocation. For everyday single-app use the gap is negligible, but for multitasking endurance, the extra 4 GB provides a tangible buffer that the Realme P4 Pro cannot match.

The rear camera systems tell very different stories. The Realme P4 Pro pairs a 50 MP primary lens with a 2 MP depth sensor — a fairly modest dual-camera setup. The Vivo T4 Pro counters with a triple-camera array: 50 MP + 50 MP + 2 MP, meaning it adds a full-resolution secondary lens (likely an ultrawide) rather than a token depth sensor. Beyond versatility, Vivo's primary lens also opens to f/1.8 versus the Realme's f/2.2, allowing more light in per shot — a meaningful low-light advantage. Add in Vivo's 3x optical zoom (the Realme offers none), and the gap in photographic range and flexibility is substantial.

Video recording flips the script. The Realme P4 Pro can capture 4K footage at 60 fps, while the Vivo T4 Pro tops out at 4K@30 fps. For users who shoot action, sports, or fast-moving subjects, 60 fps delivers noticeably smoother footage and more usable frames for slow-motion editing. Both phones support OIS, phase-detection autofocus during recording, and slow-motion modes, so the fundamentals are equally solid — but the Realme's higher frame rate ceiling is a genuine differentiator for video-focused users.

On the selfie side, the Realme's 50 MP front camera outguns the Vivo's 32 MP sensor, which may matter to users for whom portrait and selfie quality is a priority. Overall, this category has no single winner — the Vivo T4 Pro leads in rear camera versatility thanks to its triple-lens setup, wider aperture, and optical zoom, while the Realme P4 Pro has the edge in video frame rate and front camera resolution. The right choice depends heavily on whether stills versatility or video quality matters more to the buyer.

This is a rare case of a complete dead heat. Every single software feature across this specification group is identical between the Realme P4 Pro 5G and the Vivo T4 Pro — both ship with Android 15, and both carry the exact same set of privacy controls, productivity tools, and system capabilities. From camera and microphone privacy toggles to split-screen multitasking, Picture-in-Picture, dynamic theming, and offline voice recognition, there is no functional software differentiator to speak of between the two devices based on the provided data.

A few shared limitations are worth noting for prospective buyers. Neither phone receives direct OS updates — meaning updates are routed through the manufacturer rather than pushed straight from Google, which can result in delays before new Android versions or security patches arrive on the device. Similarly, neither supports Wi-Fi password sharing or Focus Modes, features that some users coming from other ecosystems may miss.

The verdict here is an absolute tie. The operating system category provides no basis whatsoever for choosing one phone over the other — both devices offer an identical software feature set on top of Android 15, with the same strengths and the same limitations.

Battery capacity and charging speed pull in opposite directions here, making this an interesting trade-off. The Realme P4 Pro 5G packs a 7000 mAh cell against the Vivo T4 Pro's 6500 mAh — a 500 mAh gap that, while not dramatic, is meaningful in practice. A larger battery directly extends the time between charges, and for power users, travelers, or anyone away from an outlet for extended periods, the Realme's extra headroom translates to a more comfortable buffer before the phone needs a top-up.

The Vivo T4 Pro responds with slightly faster wired charging at 90W versus the Realme's 80W. The 10W difference will shave a few minutes off a full charge cycle, which matters most when a user needs a quick top-up before heading out. However, it is worth keeping in mind that the Vivo is also starting from a smaller battery, so the real-world charging time advantage may be narrower than the wattage gap suggests. Both phones include a charger in the box, and neither supports wireless or reverse wireless charging.

On balance, the Realme P4 Pro 5G holds the edge in this category. A larger battery is a more persistent, all-day advantage, whereas the Vivo's 10W charging lead delivers only a modest and situational benefit. Users who prioritize longevity over a slightly quicker top-up will find the Realme the more compelling option here.

Wired audio is off the table for both devices — neither the Realme P4 Pro 5G nor the Vivo T4 Pro includes a 3.5 mm headphone jack, so wireless listening is the primary audio path for both. Both offer stereo speakers, putting them on equal footing for media consumption without headphones. The real divergence appears in Bluetooth audio codec support, and it is a significant one.

The Realme P4 Pro supports both aptX and LDAC, while the Vivo T4 Pro supports neither. These codecs matter considerably for wireless audio quality. aptX provides noticeably lower latency than standard SBC, making it valuable for video playback and casual gaming. LDAC is the more impactful inclusion — it transmits audio at up to three times the data rate of standard Bluetooth audio, making it the codec of choice for users with high-resolution audio files or premium wireless headphones that support it. Without these codecs, the Vivo is limited to SBC or AAC depending on the connected device, which represents a real ceiling on wireless audio fidelity.

The Realme P4 Pro 5G wins this category clearly. For casual listeners the gap may be imperceptible, but for anyone with quality wireless headphones or an interest in high-fidelity audio, LDAC support alone makes the Realme the substantially more capable device here. The Vivo T4 Pro's lack of any high-quality codec support is a notable omission.

Across the broad sweep of connectivity, these two phones are remarkably well-matched. Both support 5G, dual SIM, Wi-Fi 6, Bluetooth 5.4, NFC, and USB Type-C — covering all the bases a modern user would expect. The sensor suite is equally aligned, with GPS, Galileo, gyroscope, accelerometer, compass, and fingerprint scanner present on both devices. For the vast majority of connectivity use cases, there is simply no distinction to be made.

The lone differentiator in this entire category is the infrared sensor found on the Vivo T4 Pro but absent from the Realme P4 Pro. An IR blaster lets the phone function as a universal remote control for TVs, air conditioners, set-top boxes, and other home appliances — a niche but genuinely useful feature for users who want to consolidate remote controls. It costs nothing in daily use for those who don't need it, but for those who do, it's a convenience that the Realme simply cannot replicate.

This category is essentially a tie in all meaningful respects, with the Vivo T4 Pro claiming a narrow practical edge solely due to its infrared sensor. It's a minor win, but an uncontested one — and for the right user, it's a feature worth factoring into the decision.

The miscellaneous feature set for these two devices is identical across every data point provided. Both include a video light, and neither carries a sapphire glass display, a curved display, or an e-paper display. There is nothing in this group that separates the Realme P4 Pro 5G from the Vivo T4 Pro in any meaningful way.

This is a complete tie — the provided specifications offer no basis for preferring one device over the other in this category. Buyers should weigh the differences identified in other specification groups when making their final decision.
