Realme P3 Pro 5G VS Realme P4 5G

The most consequential difference in this group comes down to water protection. The Realme P3 Pro 5G carries an IP68 rating, meaning it is fully waterproof and can withstand submersion in water — a meaningful safety net for accidental drops in sinks, pools, or rain. The Realme P4 5G, by contrast, is rated IP66, which certifies it against powerful water jets but not submersion. In practice, IP66 handles everyday splashes and rain perfectly well, but it offers notably less peace of mind in true water-immersion scenarios.

On the physical side, the P4 5G makes a clear case for in-hand comfort. It is 5 g lighter (185 g vs. 190 g), 0.7 mm thinner (7.6 mm vs. 8.3 mm), and 1.4 mm narrower (75.9 mm vs. 77.3 mm), resulting in a noticeably smaller overall volume of 94.2 cm³ compared to the P3 Pro's 104.9 cm³ — roughly a 10% reduction. That slimmer, lighter profile translates to a more pocketable device that is easier to grip and use one-handed over long sessions. Heights are nearly identical at around 163 mm, so neither phone feels taller than the other.

Neither device is rugged-built or foldable, so those factors are a wash. The verdict depends on priorities: the P3 Pro 5G holds a clear edge in water protection thanks to its IP68 certification, while the P4 5G has the advantage in everyday ergonomics with its slimmer and lighter body. Users who frequently work near water should lean toward the P3 Pro; those who prioritize a sleeker, more comfortable form factor will prefer the P4.

Both phones use OLED/AMOLED panels, so they share the core benefits of that technology — deep blacks, vibrant colors, and strong contrast. Screen sizes are close (6.83″ on the P3 Pro vs. 6.77″ on the P4), and pixel density is virtually identical at around 390 ppi, so both will appear equally sharp to the naked eye. Where the two diverge meaningfully is in refresh rate and, most dramatically, brightness.

The Realme P4 5G runs at a 144Hz refresh rate versus the P3 Pro's 120Hz, which produces noticeably smoother scrolling and animations — a real difference gamers and heavy scrollers will feel daily. Far more impactful, however, is the brightness gap: the P4 delivers 1600 nits of typical brightness against the P3 Pro's 600 nits. That is not a marginal improvement — it is the difference between a display that remains clearly legible outdoors in direct sunlight and one that can become a struggle to read. For anyone who regularly uses their phone outside, this is arguably the single most important hardware differentiator in this group. The P4 also includes an Always-On Display, a convenience the P3 Pro lacks entirely.

Resolution is the one area where the P3 Pro pushes back, with a 1272 x 2800 px panel versus the P4's 1080 x 2392 px — but at near-identical pixel densities, this difference is practically invisible in day-to-day use. On balance, the P4 5G holds a clear display advantage for most users, driven by its substantially higher brightness and faster refresh rate, with Always-On Display as an added perk. The P3 Pro's higher raw resolution offers negligible real-world benefit to offset these gaps.

At the silicon level, these two phones take different architectural approaches. The Realme P3 Pro 5G runs on the Qualcomm Snapdragon 7s Gen 3 with an Adreno 710 GPU, while the Realme P4 5G is powered by the MediaTek Dimensity 7400 with a Mali G615 MC2 GPU. Both are fabbed on a 4 nm process and share an 8-thread big.LITTLE layout, DirectX 12 support, and virtually identical GPU clock speeds — so neither has a clear graphics edge on paper. The CPU peak clock slightly favors the P4 at 2.6 GHz across its four performance cores, compared to the P3 Pro's top speed of 2.5 GHz, though the P3 Pro's cluster structure is more granular with three mid-tier cores as well.

The RAM story is where things get interesting. The P3 Pro ships with 12 GB of RAM versus the P4's 8 GB, giving it more headroom for heavy multitasking and keeping more apps live in memory simultaneously. Counterintuitively, however, the P4's RAM runs at 6400 MHz — double the P3 Pro's 3200 MHz — meaning individual memory operations complete faster even if there is less total capacity. Both share the same 25.6 GB/s maximum memory bandwidth and DDR5 standard, and both support up to 16 GB maximum, so the gap could narrow if either device uses virtual RAM expansion.

For most everyday workloads, the P4's faster RAM speed and slightly higher peak CPU clock keep it competitive despite the lower RAM capacity. The P3 Pro's 12 GB RAM gives it a tangible edge for sustained multitasking — running many apps simultaneously without reloading. On raw performance metrics from the provided data, this group is closely contested, but the P3 Pro holds a practical advantage for memory-intensive use, while the P4 may respond more crisply in burst tasks thanks to its faster RAM throughput.

Strip away the shared specs — identical 50 & 2 MP dual rear setups, matching 16 MP front cameras, and the same 4K/30fps video ceiling — and two meaningful differences emerge. First, the Realme P3 Pro 5G includes optical image stabilization (OIS), which the P4 5G lacks entirely. OIS physically compensates for hand movement during shooting, making a tangible difference when capturing handheld video, shooting in low light with slower shutter speeds, or taking photos while in motion. Its absence on the P4 means stabilization falls entirely to software, which is generally less effective.

The second differentiator is aperture. The P3 Pro's primary lens sits at f/2.4, while the P4's opens slightly wider at f/2.2. A wider aperture allows more light onto the sensor, which can aid low-light performance — though without OIS to steady the shot, that advantage may be partially offset in practice. The P4 also carries a CMOS sensor designation that the P3 Pro's specs do not confirm, though this alone is not a decisive differentiator at this tier. Both phones share the same secondary 2 MP lens with an f/1.8 aperture, identical autofocus capabilities including phase-detection, and an equally matched manual controls feature set.

Taken together, the P3 Pro 5G holds the stronger camera package for most users. OIS is a high-impact hardware feature that benefits stills and video alike, and its presence outweighs the P4's marginal aperture advantage on the primary lens. Videographers and anyone who shoots frequently in challenging conditions will notice the difference most acutely.

Rarely does a spec group tell such a clear story: the Realme P3 Pro 5G and Realme P4 5G are absolutely identical across every single operating system data point provided. Both run Android 15, carry the same privacy toolkit — including location controls, camera/microphone permissions, and app tracking blockers — and share the same set of productivity and usability features, from split-screen and Picture-in-Picture to dynamic theming, offline voice recognition, and Live Text.

This is a complete tie in this category. A user switching between the two devices would notice no software difference whatsoever based on the provided specs. Neither phone receives direct OS updates, and neither includes features like Wi-Fi password sharing, focus modes, or Quick Start — absences that apply equally to both.

Charging speed is a non-issue here — both phones top out at 80W fast charging, meaning refill times from empty will be essentially the same. Neither supports wireless charging, and both have sealed, non-removable batteries. The only variable that matters in this group is capacity, and it is a significant one: the Realme P4 5G packs a 7000 mAh cell against the Realme P3 Pro 5G's 6000 mAh — a 17% larger reserve.

In practical terms, that extra 1000 mAh translates to meaningfully more time between charges, particularly relevant for heavy users who stream video, game, or spend long hours away from a power source. It is worth noting that the P4's brighter display and higher refresh rate from the display group could partially offset the raw capacity advantage in real-world endurance — but on the battery specs alone, the larger cell is an unambiguous plus.

The P4 5G holds a clear edge here. With identical charging infrastructure on both sides, the bigger battery is a straightforward win for users who prioritize battery longevity and want more confidence going through a full day — or beyond — without reaching for a charger.

Audio is another category where these two phones are impossible to separate. The Realme P3 Pro 5G and Realme P4 5G share an identical feature set: both have stereo speakers, both drop the 3.5mm headphone jack, and neither supports high-fidelity wireless codecs like LDAC or aptX Lossless. Users who rely on wired headphones will need an adapter or USB-C headphones on either device.

This is a complete tie. There is no audio specification in the provided data that distinguishes one phone from the other, and neither product offers an advantage for wired or wireless listening quality over its counterpart.

Three meaningful differences surface in this group, and they cut in opposite directions. The Realme P3 Pro 5G supports Wi-Fi 6 (802.11ax) in addition to Wi-Fi 4 and 5, while the Realme P4 5G tops out at Wi-Fi 5. On a compatible router, Wi-Fi 6 delivers higher throughput, lower latency, and better performance in congested environments — a genuine advantage for users on modern home or office networks. The P4, however, counters with two wins of its own: NFC support and a newer Bluetooth 5.4 (versus the P3 Pro's 5.2).

NFC is the more impactful of those two advantages for most users — it enables contactless payments, quick device pairing, and data transfers, none of which are possible on the P3 Pro. Bluetooth 5.4 over 5.2 brings incremental improvements in connection reliability and efficiency, though the practical day-to-day difference is modest. Both phones share 5G, dual-SIM, USB Type-C with USB 2.0, a fingerprint scanner, and a standard sensor suite including GPS, gyroscope, accelerometer, and compass — so the feature parity outside these three points is high.

This group is closely contested, but the P4 5G has a slight overall edge for most users. NFC alone is a broadly useful daily-driver feature that the P3 Pro cannot replicate. The P3 Pro's Wi-Fi 6 advantage is real but only relevant to those with compatible networking hardware — making the P4's connectivity package more universally impactful.

The miscellaneous specs offer nothing to separate these two devices. The Realme P3 Pro 5G and Realme P4 5G are identical across every data point in this group — both include a video light, and neither features a sapphire glass display, curved screen, or e-paper display. This is a complete tie with no differentiating factors to analyze.
