Infinix Note 50s 5G 128GB VS Realme P4 5G

In terms of physical form, these two phones are remarkably close. Both share an identical 7.6 mm thickness and are similarly tall — 164.3 mm for the Infinix Note 50s 5G versus 163.3 mm for the Realme P4 5G — making them functionally equivalent in the hand. The Infinix is marginally narrower at 74.5 mm versus 75.9 mm, which can subtly improve one-handed reachability on wide screens. The weight difference of 180 g versus 185 g is a mere 5 g — imperceptible in daily use and not a meaningful differentiator.

Where the two phones genuinely diverge is water resistance. Both carry an IP rating, but the Realme P4 5G holds an IP66 certification, while the Infinix Note 50s 5G is rated IP64. This is a real-world distinction: the ″6″ in the first digit means both offer the same dust protection, but the second digit tells a different story — IP64 guards against water splashes from any direction, whereas IP66 withstands powerful, sustained water jets. For users who work outdoors, near sinks, or in rainy conditions, the Realme's rating provides meaningfully stronger protection.

Overall, the Realme P4 5G holds a clear edge in this category, specifically due to its superior IP66 water resistance rating. The rest of the design specs are so closely matched that they effectively cancel out. If durability and water protection matter to you, the Realme is the stronger choice here.

The display credentials of these two phones are strikingly similar at the headline level. Both feature an OLED/AMOLED panel at virtually the same size — 6.78″ on the Infinix Note 50s 5G and 6.77″ on the Realme P4 5G — with matching 144Hz refresh rates and identical 1080p resolutions. The pixel density difference of 393 ppi versus 388 ppi is invisible to the human eye in normal use. In practice, users of either phone will enjoy the same fluid scrolling, deep blacks, and vibrant contrast that AMOLED technology delivers, along with the battery-saving convenience of an Always-On Display.

The single meaningful differentiator in this category is glass protection. The Infinix ships with branded damage-resistant glass, while the Realme P4 5G does not specify any such protection. This matters in everyday durability: branded protective glass — such as Gorilla Glass or its equivalents — significantly reduces the risk of scratches from keys or rough surfaces and improves resilience against accidental drops. The absence of this feature on the Realme means its screen may be more vulnerable to everyday wear over time.

On display quality alone, these phones are essentially tied. However, the Infinix Note 50s 5G earns a narrow edge in this group thanks to its damage-resistant glass, which adds a practical layer of long-term screen durability that the Realme P4 5G does not offer.

Under the hood, these two phones share a remarkable amount of silicon DNA. Both run on MediaTek 4nm chipsets with identical GPU configurations — the Mali G615 MC2 clocked at 1047 MHz — the same 8GB of DDR5 RAM at 6400 MHz, and matching 8-thread big.LITTLE CPU architectures. For everyday tasks, gaming, and multitasking, users of either device will land in essentially the same performance bracket.

The chipset generation does create a subtle but real difference. The Realme P4 5G runs the Dimensity 7400, while the Infinix Note 50s 5G uses the Dimensity 7300. The tangible expression of this is in the peak CPU clock: the Realme's performance cores reach 2.6 GHz versus 2.5 GHz on the Infinix. In sustained workloads — video rendering, large app compilations, or extended gaming sessions — this marginal headroom can translate to slightly snappier responsiveness, though the gap is narrow enough that most users won't notice it in casual use. The more impactful practical difference is storage: the Realme ships with 256GB of base storage compared to 128GB on the Infinix, which is a meaningful advantage for users who store large media libraries or avoid cloud storage.

The Realme P4 5G holds a clear edge in this group. Its newer chipset and doubled base storage make it the stronger value proposition for performance-conscious buyers, even if the day-to-day experience difference between the two chipsets remains modest.

Camera hardware on both phones follows a dual-lens rear setup with identical 4K/30fps video capability and a broadly equivalent feature set — phase-detection autofocus, slow-motion recording, HDR mode, and a solid range of manual controls. Where they part ways is in the primary sensor resolution and aperture. The Infinix Note 50s 5G leads with a 64 MP main sensor at f/1.8, while the Realme P4 5G opts for a 50 MP main sensor. In practical terms, the higher megapixel count on the Infinix allows for more aggressive cropping while retaining detail — useful for users who frequently zoom in post-capture or print large photos.

On the front camera, the dynamic flips. The Realme edges ahead with a 16 MP selfie shooter compared to the Infinix's 13 MP, which could yield marginally more detailed selfies. However, the Infinix counters with a wider f/2.2 front aperture versus the Realme's f/2.4, meaning it lets in more light — a tangible benefit for selfies in dimly lit environments. The Infinix also features a dual-tone LED flash on the rear, which produces more natural-looking flash photography by blending warm and cool tones, compared to the Realme's single-LED setup.

On balance, the Infinix Note 50s 5G holds a narrow edge in this category. Its higher-resolution main sensor, brighter front aperture, and dual-tone flash collectively give it a slight advantage for users who prioritize photo quality across varied shooting conditions. The Realme's higher selfie megapixel count is its strongest counter-point, but it does not fully offset the Infinix's broader camera advantages.

This is the rarest outcome in a head-to-head comparison: a complete dead heat. Every single operating system specification provided for the Infinix Note 50s 5G and the Realme P4 5G is identical. Both ship with Android 15, carry the same privacy toolkit — including location controls, camera/microphone permissions, and app tracking blockers — and support the same set of productivity and usability features such as split-screen, Picture-in-Picture, dynamic theming, and offline voice recognition.

The feature parity extends to the finer details as well. Neither phone offers direct OS updates, Wi-Fi password sharing, focus modes, or PC mode functionality — and both support on-device machine learning, a battery health check, and multi-user profiles. For a buyer weighing these two devices, the software experience will be effectively indistinguishable out of the box.

This group is a definitive tie. The operating system cannot serve as a deciding factor between these two phones — any differentiation in day-to-day software experience would come from each manufacturer's custom Android skin rather than from the underlying OS capabilities reflected in this data.

Battery is where the Realme P4 5G makes its most emphatic statement in this entire comparison. Its 7000 mAh cell dwarfs the Infinix Note 50s 5G's already respectable 5500 mAh — a 27% capacity advantage that translates directly into real-world endurance. For heavy users who stream video, game, or navigate frequently, that extra 1500 mAh can mean the difference between reaching the end of a long day comfortably and scrambling for a charger by evening.

The charging story is equally lopsided in the Realme's favor. At 80W, the Realme charges significantly faster than the Infinix's 45W — and it does so from a larger starting capacity. This combination means the Realme not only lasts longer between charges but also recovers faster when it does need topping up. Both phones include a charger in the box and support fast charging, so neither user is left waiting for optional accessories.

The Realme P4 5G wins this category decisively. A larger battery and nearly double the charging wattage make it the clear choice for anyone who prioritizes battery life and charging convenience — and the margin here is wide enough to be a genuinely compelling differentiator between these two devices.

Audio is another category where these two phones arrive at exactly the same destination. Both the Infinix Note 50s 5G and the Realme P4 5G drop the 3.5mm headphone jack — a now-common trade-off in mid-range smartphones that pushes users toward Bluetooth or USB-C audio solutions. On the upside, both offer stereo speakers, which meaningfully improves the experience for media consumption, gaming, and hands-free calls compared to a single-driver setup.

Neither phone supports any high-resolution Bluetooth audio codec — aptX, aptX HD, aptX Adaptive, aptX Lossless, and LDAC are all absent on both devices. This means wireless audio quality is capped at standard Bluetooth SBC or AAC levels, which is perfectly adequate for most listeners but will disappoint audiophiles who pair their phone with high-end wireless headphones capable of lossless or hi-res transmission.

This group is a complete tie. The audio hardware and feature set are identical across both phones, and neither holds any advantage. Buyers with strong audio priorities should note that the shared absence of hi-res Bluetooth codecs and a headphone jack applies equally to both options.

Across the broad connectivity landscape, these two phones are closely matched — both support 5G, dual SIM, NFC, USB Type-C, Bluetooth 5.4, and an identical sensor suite including GPS, gyroscope, accelerometer, and compass. For most users, the day-to-day connected experience will feel indistinguishable. That said, two specific differences are worth calling out.

The first is Wi-Fi. The Infinix Note 50s 5G supports Wi-Fi 6 (802.11ax), while the Realme P4 5G tops out at Wi-Fi 5 (802.11ac). Wi-Fi 6 offers better performance in congested network environments — such as offices, apartments, or public spaces with many connected devices — as well as improved power efficiency during wireless activity. It's not a dramatic difference for a single user on an uncrowded router, but it is a genuine future-proofing advantage as Wi-Fi 6 routers become the norm. The second differentiator is the infrared sensor present on the Infinix but absent on the Realme. This allows the Infinix to function as a universal remote control for TVs, air conditioners, and other IR-compatible appliances — a niche but surprisingly practical feature for everyday home use.

The Infinix Note 50s 5G takes this category by a clear margin. Both Wi-Fi 6 support and the infrared sensor are meaningful, real-world additions that the Realme P4 5G simply does not offer, giving the Infinix a tangible connectivity edge.

This is a compact spec group with limited data points, but one meaningful distinction emerges. Both phones share a video light and neither features sapphire glass or an e-paper display — those attributes cancel out entirely. The sole differentiator is display curvature: the Infinix Note 50s 5G has a curved display, while the Realme P4 5G uses a flat panel.

Curved displays are largely a matter of aesthetic preference and ergonomics. They can lend a phone a more premium, seamless look and may feel more natural when swiping in from the edges. The trade-off, however, is that curved screens are generally more susceptible to accidental edge touches and can be harder to protect with standard screen protectors. Flat displays, by contrast, offer easier case compatibility and are often preferred by users who prioritize practicality over visual flair.

Neither approach is objectively superior — it comes down to personal preference. However, since the curved display represents the only differentiating feature in this group, the Infinix Note 50s 5G holds a nominal edge for users who value a more distinctive, premium-feeling form factor, while the Realme's flat screen will appeal to those who prioritize practicality and accessory compatibility.
