Realme P3 VS Realme P4 5G

In terms of physical form, the two devices are remarkably close. Both share nearly identical footprints — 163.2 mm tall for the P3 versus 163.3 mm for the P4 5G, with widths of 75.7 mm and 75.9 mm respectively — meaning neither will feel meaningfully larger or smaller in the hand. Where a real difference emerges is in slimness and weight: the P4 5G is noticeably thinner at 7.6 mm versus 8 mm, and lighter at 185 g versus 194 g. A 9-gram difference may sound trivial, but combined with the reduced thickness, it translates to a more premium, pocketable feel during extended daily use.

The most consequential divergence in this group, however, is water protection. The Realme P3 carries an IP68 rating, meaning it is fully waterproof and can withstand submersion in water — a standard typically associated with flagship-tier durability. The P4 5G steps down to IP66, which certifies resistance to powerful water jets but offers no protection against submersion. In practical terms, the P3 can survive an accidental drop in a sink or pool, while the P4 5G cannot.

Overall, the P4 5G has a slight edge in ergonomics thanks to its slimmer and lighter profile, but the Realme P3 holds a clear and meaningful advantage in durability — IP68 versus IP66 is not a minor spec gap. For users who prioritize peace of mind around water exposure, the P3 is the stronger choice in this category.

Both phones use an OLED/AMOLED panel, so the fundamentals — deep blacks, vivid colors, and strong contrast — are shared across the board. The P4 5G gets a marginally larger 6.77-inch screen versus the P3's 6.67-inch, but the real-world visual difference is negligible. Pixel density tells a similar story: 395 ppi on the P3 versus 388 ppi on the P4 5G — both are sharp enough that individual pixels are indistinguishable at normal viewing distances, making this gap practically irrelevant.

Where the P4 5G pulls ahead is refresh rate. Its 144Hz panel delivers noticeably smoother scrolling, animations, and gaming responsiveness compared to the P3's already-capable 120Hz display. For casual users the difference is subtle, but for anyone sensitive to motion fluidity — particularly mobile gamers — 144Hz offers a tangible improvement. The P4 5G also supports Always-On Display, a convenience feature absent on the P3 that lets users check the time or notifications without fully waking the screen.

The Realme P4 5G holds a clear edge in this category. The higher refresh rate and Always-On Display are both meaningful real-world upgrades, and neither product has HDR10, HDR10+, or Dolby Vision support to offset the balance. For display-focused buyers, the P4 5G is the stronger pick.

The shared specs here are substantial: both phones run on a 4 nm process, pack 8GB of DDR5 RAM, offer up to 16GB maximum memory, and deliver 256GB of internal storage. The architectural parity ends there, though. On raw CPU clocks, the P4 5G's Dimensity 7400 runs its performance cores at 2.6 GHz — a step above the P3's Snapdragon 6 Gen 4 peak of 2.3 GHz — suggesting a modest but real lead in processor-bound tasks like app launches and multitasking.

The memory subsystem gap is harder to dismiss. The P4 5G's RAM operates at 6400 MHz versus 2750 MHz on the P3, and its maximum memory bandwidth reaches 25.6 GB/s compared to just 12 GB/s. Higher bandwidth means the processor can feed data to and from memory far more quickly — a direct benefit for heavy multitasking, large file handling, and GPU-intensive workloads. Speaking of GPU, the P4 5G's Mali G615 MC2 runs at 1047 MHz versus the Adreno 810's 800 MHz — a meaningful clock speed advantage that, combined with the wider memory bandwidth, points to stronger graphics throughput for gaming and media processing.

The Realme P4 5G holds a clear performance edge in this category. Its faster CPU cores, dramatically superior memory bandwidth, and higher GPU clock speed all point in the same direction. The P3 is no slouch, but the data consistently favors the P4 5G for users who push their devices hard.

Strip away the labels and these two camera systems are nearly twins: both offer a 50 MP + 2 MP dual rear setup, a 16 MP front camera, 4K at 30fps video, phase-detection autofocus, slow-motion, HDR, and an identical manual controls suite. For the vast majority of shooting scenarios, users of either phone will be working with the same fundamental toolset.

The one difference that actually matters is optical image stabilization (OIS). The P3 has it; the P4 5G does not. OIS physically compensates for hand tremor during capture, which makes a tangible difference in low-light photos, handheld video smoothness, and any shot taken without a completely steady hand. Its absence on the P4 5G is a genuine trade-off — especially given that this is otherwise the more performance-oriented device in the lineup.

For camera buyers, the Realme P3 holds a clear and practical advantage here solely on the strength of OIS. It is not a sweeping difference across the full camera experience, but in the conditions where stabilization matters most — dim environments, video recording, or quick candid shots — the P3 will consistently produce sharper, steadier results.

This is the rare category where the comparison ends before it begins. Every single software specification provided — from the base Android 15 version down to privacy controls, dark mode, split-screen, Picture-in-Picture, on-device machine learning, and multi-user support — is identical between the two devices. There is not one meaningful point of differentiation in the data.

This is a complete tie. Buyers should treat both phones as offering an equivalent software experience and look to other categories to inform their decision.

Battery is one of the most decisive categories in this comparison. The P4 5G packs a 7000 mAh cell against the P3's already-generous 6000 mAh — a 1000 mAh difference that represents roughly a 17% larger reserve. In practice, that gap translates directly to more screen-on time between charges, making the P4 5G the stronger pick for heavy users, frequent travelers, or anyone who regularly ends the day in the red.

Charging speed compounds the advantage. The P4 5G supports 80W fast charging versus 45W on the P3 — nearly double the wattage. A larger battery that also refills significantly faster is an uncommon combination; typically, bigger cells take longer to top up. Here, the P4 5G sidesteps that trade-off entirely. Neither phone offers wireless charging, so that shared omission is a non-factor in the decision.

The Realme P4 5G wins this category decisively. More capacity and dramatically faster charging together make it the clear choice for battery-conscious buyers, with no offsetting advantage on the P3's side.

Audio is another category where the two devices are indistinguishable on paper. Both feature stereo speakers and drop the 3.5 mm headphone jack, and neither supports any high-resolution Bluetooth audio codec — no aptX, no LDAC, no aptX HD or any of its variants. The experience wired headphone users and audiophiles get from either device is equally constrained by these shared omissions.

This is a complete tie. Audio should carry no weight in a decision between these two phones, and buyers with strong audio priorities should factor in third-party accessories rather than expecting differentiation at the hardware level.

The connectivity picture is largely shared territory — both phones offer 5G, NFC, USB-C, dual SIM, GPS with Galileo, and a fingerprint scanner. The differences, while few, are meaningful. On Wi-Fi, the P3 pulls ahead by supporting Wi-Fi 6 (802.11ax) in addition to Wi-Fi 4 and 5, whereas the P4 5G tops out at Wi-Fi 5. Wi-Fi 6 delivers faster throughput and significantly better performance in congested environments — a real-world benefit in offices, apartments, or anywhere many devices share the same network.

The trade-offs cut both ways, however. The P4 5G carries the newer Bluetooth 5.4 versus 5.2 on the P3 — an incremental but genuine upgrade in connection stability and efficiency for wireless peripherals and audio devices. The P3, meanwhile, includes an infrared sensor that the P4 5G lacks entirely. An IR blaster lets the phone act as a universal remote for TVs and home appliances — a niche but genuinely useful feature for those who rely on it.

On balance, the Realme P3 holds a slight connectivity edge. Wi-Fi 6 support is a more broadly impactful upgrade than the Bluetooth version bump the P4 5G offers, and the added IR blaster is a bonus feature with no equivalent on the other side. Neither device dominates outright, but the P3 delivers more connectivity value for most users.

The miscellaneous specs provided here offer no basis for differentiation whatsoever. Both devices share every attribute in this group — a video light, no sapphire glass, no curved display, and no e-paper screen. This is a complete tie, and this category should play no role in the decision between these two phones.
