Infinix Note 50 Pro 4G VS Infinix Note 50 Pro Plus 5G

Both the Infinix Note 50 Pro 4G and the Note 50 Pro Plus 5G share the same footprint in terms of height and width — 163.3–163.4 mm tall and approximately 74.4–74.5 mm wide — making them virtually identical to hold in one hand. The key physical difference lies in thickness and weight: the Pro 4G measures just 7.3 mm thick and weighs 198 g, while the Pro Plus 5G is 8 mm thick and weighs 209 g. That 11-gram difference and 0.7 mm extra girth are attributable to the 5G model likely housing a larger battery or additional radio hardware, and while these gaps are modest on paper, over a full day of use the slimmer, lighter Pro 4G will feel noticeably more comfortable for extended one-handed use or pocketing.

Both devices share an IP64 rating, meaning they offer the same level of protection: full dust resistance and protection against water splashes from any direction. Neither has a rugged build or a foldable form factor, so they occupy the same conventional, everyday-use design category. For users who want splash and dust peace of mind without premium ruggedization, both deliver equally here.

On design, the Infinix Note 50 Pro 4G holds a clear ergonomic edge — it is meaningfully slimmer and lighter without sacrificing any protection rating. The Pro Plus 5G's added bulk is a trade-off that comes with its 5G capabilities, not a design advantage. If portability and in-hand comfort are priorities, the 4G model wins this category.

The display category is a straight tie. Both the Infinix Note 50 Pro 4G and the Note 50 Pro Plus 5G are equipped with identical 6.78″ OLED/AMOLED panels running at 1080 x 2436 px resolution and a pixel density of 393 ppi — sharp enough that individual pixels are indistinguishable at normal viewing distances. The 144Hz refresh rate means scrolling, animations, and gaming all feel exceptionally fluid, a feature that was once reserved for flagship devices.

Neither screen supports HDR10, HDR10+, or Dolby Vision, which means content from streaming platforms will not unlock premium dynamic range tiers. That is a shared limitation worth noting for media-heavy users. On the positive side, both include an Always-On Display, which allows glanceable notifications and clock info without fully waking the screen — a practical day-to-day convenience that works well with OLED technology since only active pixels consume power.

There is no differentiator to call here: every display spec is identical across both devices. Users choosing between the two can rule out the screen as a deciding factor entirely — this group is a complete tie.

This is where the two phones diverge most dramatically. The Note 50 Pro 4G runs on a MediaTek Helio G100 built on a 6 nm process, while the Pro Plus 5G steps up to the MediaTek Dimensity 8350 on a more advanced 4 nm node. The smaller fabrication process is not just a number — it translates directly into greater power efficiency and thermal headroom, allowing the Dimensity 8350 to sustain higher performance without throttling under sustained workloads. The AnTuTu scores tell the story bluntly: 438,000 for the Pro 4G versus 1,420,000 for the Pro Plus 5G — the 5G model scores more than three times higher, placing it in a genuinely different performance tier.

The memory architecture gap is equally significant. The Pro 4G uses DDR4 RAM at 4266 MHz with a maximum bandwidth of 17.1 GB/s, whereas the Pro Plus 5G deploys DDR5 RAM at 8533 MHz and delivers up to 68.2 GB/s of bandwidth — four times as much. In practice, this means faster app launches, smoother multitasking, and quicker data-heavy operations. The Pro Plus 5G also supports up to 24 GB of maximum RAM versus the Pro 4G's 12 GB ceiling, giving it far more headroom for future configurations. On the GPU side, the Mali G615 MC6 clocked at 1400 MHz in the Pro Plus 5G outpaces the Pro 4G's Mali G57 at 1000 MHz, and its support for DirectX 12 versus DirectX 11 means better compatibility with modern graphics workloads and gaming APIs.

The verdict here is unambiguous: the Infinix Note 50 Pro Plus 5G wins the performance category by a wide margin across every measurable dimension — CPU speed, GPU capability, memory bandwidth, and overall benchmark throughput. The Pro 4G is adequate for everyday tasks, but users who game, multitask heavily, or want longevity as apps grow more demanding will find the Pro Plus 5G in a different league entirely.

The rear camera systems share a 50 MP primary sensor and an 8 MP lens in common, but the Note 50 Pro Plus 5G adds a third shooter — a dedicated 50 MP telephoto lens — that fundamentally changes what the camera system can do. Paired with 3x optical zoom, this gives the Pro Plus 5G true lossless zoom capability, meaning portraits, distant subjects, and compressed-perspective shots are all captured with genuine optical magnification rather than digital cropping. The Pro 4G offers 0x optical zoom, so any zoom beyond the native focal length degrades image quality. For users who care about versatility and shooting flexibility, this is a meaningful gap.

Video recording tells a similar story. The Pro 4G tops out at 1440p at 30 fps, while the Pro Plus 5G records up to 4K at 60 fps — a substantial jump that matters for anyone shooting content intended for large screens or post-production cropping. Both phones support OIS, phase-detection autofocus, continuous autofocus during recording, slow-motion, HDR mode, and a broad set of manual controls, so the shooting experience and feature parity are strong across both devices at their respective resolution ceilings.

The front camera and flash configurations are identical at 32 MP with a 2.2f aperture, and neither device offers a front-facing flash or under-display camera. The conclusion here is clear: the Infinix Note 50 Pro Plus 5G holds a decisive camera advantage, driven by its triple-lens system with optical zoom and significantly higher video resolution ceiling. The Pro 4G is competent, but it lacks the hardware to compete on zoom range or video quality.

Running Android 15 on both devices, the software experience is functionally identical across the board. Neither phone receives direct OS updates from Google — both rely on Infinix's own update cadence — which is a shared limitation worth keeping in mind for users who prioritize timely security patches and feature rollouts. Beyond that, the feature set is extensive and modern: on-device machine learning, dynamic theming, Live Text, Picture-in-Picture, split-screen multitasking, and full-page screenshots are all present on both handsets.

Privacy-conscious users will find the same toolkit on either device — camera and microphone access controls, location privacy options, app tracking blocks, and clipboard warnings are all included. Notable shared absences include cross-site tracking protection and Wi-Fi password sharing, two features increasingly common on competing platforms. Neither omission is a dealbreaker, but they are consistent gaps across the lineup.

Since every single software specification is mirrored exactly between the two phones, the operating system category is a complete tie. The choice between the Note 50 Pro 4G and the Pro Plus 5G will not be influenced in any way by software — users on either device get the same Android 15 experience, the same privacy controls, and the same feature set out of the box.

Matching spec for spec, both the Infinix Note 50 Pro 4G and the Note 50 Pro Plus 5G carry a 5200 mAh battery — a generous capacity that comfortably supports full-day usage for most users, and often stretches into a second day under moderate workloads. Wired fast charging tops out at 90W on both devices, which at that speed typically means a near-full charge in well under an hour, significantly reducing the friction of daily charging routines.

The charging versatility is equally matched. Both phones support 30W wireless charging, a rate that is fast enough for practical overnight or desk-based top-ups without being tethered to a cable. More notably, both include reverse wireless charging at 7.5W, allowing either device to act as a wireless charging pad for accessories like earbuds or a friend's phone — a feature that remains uncommon at this price tier. A charger is included in the box with both models, which is worth highlighting given the industry trend of omitting it.

There is nothing to separate these two phones on battery: every specification — capacity, wired speed, wireless speed, reverse charging, and bundled accessories — is identical. This category is a complete tie, and battery life or charging capability should play no role in deciding between the two models.

Audio hardware is identical on both devices, so the listening experience starts from the same foundation. Neither the Note 50 Pro 4G nor the Pro Plus 5G includes a 3.5 mm headphone jack, which means wired audio requires a USB-C adapter — a trade-off that has become commonplace but still matters to users with existing wired headphone collections. On the positive side, both feature stereo speakers, which produce noticeably wider, more immersive sound compared to mono setups — particularly relevant for media consumption, gaming, and speakerphone calls.

Wireless audio quality is capped identically on both phones. The absence of aptX, LDAC, aptX HD, or any high-resolution Bluetooth audio codec means that even premium wireless headphones supporting these standards will fall back to standard SBC or AAC transmission. For casual listeners this is unlikely to matter, but audiophiles pairing high-end Bluetooth headphones should be aware of this shared ceiling. A built-in FM radio is present on both, a feature increasingly rare on modern smartphones that adds offline listening utility without consuming data.

With no differentiating spec anywhere in this category, audio is another complete tie. Neither device holds an advantage — the shared strengths and shared limitations apply equally to both, and audio preference should carry no weight in the buying decision between these two models.

The most consequential difference in this category is right in the product names: the Note 50 Pro Plus 5G supports 5G connectivity while the Pro 4G does not. For users in areas with 5G coverage, this means significantly faster mobile data speeds and lower latency — relevant not just today but increasingly so as 5G infrastructure continues to expand. Beyond cellular, both phones share the same Wi-Fi 5 (802.11ac) and Bluetooth 5.4 support, so wireless performance on local networks is evenly matched.

Two smaller but notable divergences separate the feature sets further. The Pro 4G includes a heart rate monitor, which the Pro Plus 5G lacks — a somewhat unusual reversal where the less powerful model carries an extra health sensor. Going the other direction, the Pro Plus 5G adds an infrared sensor, absent on the Pro 4G, enabling it to function as a universal remote control for TVs and appliances — a practical convenience that a dedicated segment of users genuinely values. These swapped features partially offset each other depending on individual priorities.

Shared fundamentals — NFC, fingerprint scanner, GPS with Galileo support, gyroscope, accelerometer, dual SIM, and USB Type-C — are present on both, ensuring neither device feels stripped down for everyday use. Overall though, the Note 50 Pro Plus 5G holds the connectivity edge, primarily due to 5G support, which represents a more future-proof and broadly impactful advantage than the heart rate sensor the Pro 4G carries in return.

The miscellaneous category offers very little to analyze — both the Infinix Note 50 Pro 4G and the Note 50 Pro Plus 5G share every spec listed here without exception. Both include a video light, useful for illuminating subjects during video calls or recording in low-light conditions, and neither features a sapphire glass display, curved screen, or e-paper panel.

This is a complete tie with no differentiators present. The data in this group carries no weight in the decision between the two models.
