realme P4x, the review: the battery phone with the LED at the back focuses on longevity

realme P4x

The realme P4x is an affordable battery phone that focuses almost entirely on a 7,500 mAh battery and 45W fast charging. However, the model available on Italian shelves does not match the version marketed in other Global markets, which varies in processor, battery capacity, and some certifications. Instead, the European market retains an exclusive feature, the Pulse Light, a customizable LED ring mounted on the back next to the camera module.

We tested the Italian variant in the 4+256 GB configuration, in Rally White color, for several days to understand how much the technical compromises of a device that plays almost all its game under €250 weigh.

Technical specifications and differences from the Global market

The name P4x does not guarantee the same technical specifications worldwide. The Italian variant of realme P4x adopts a Unisoc T7250 processor with 4G support, while many Global models integrate more powerful 5G chips such as the Dimensity 7400 Ultra.

The battery follows the same script: the European variant features a 7,500 mAh cell with 45W charging, while its capacity in other markets typically hovers around 7,000 mAh, with capacities reaching up to 8,000 mAh in other destinations. On the back, the Italian variant also adds an exclusive feature, the Pulse Light, in addition to MIL-STD-810H military-grade certification for shock and drop resistance, which is absent in many Global versions.

The differences do not end here. The global variant adopts UFS 3.1 storage, while the Italian model relies on eMMC 5.1 memory: a choice that reflects in the sequential read and write times, slower than what mid-range users are accustomed to, as confirmed by our tests reported in the chapter dedicated to hardware and performance. The display is a 6.8" LCD with HD+ resolution (720 x 1,570 pixels), with a maximum refresh rate of 120 Hz and touch sampling rate of 240 Hz.

The model under review measures 166.48 x 78.23 x 8.78 mm and weighs 219 grams, featuring an ArmorShell structure and IP64 certification against dust and water penetration, along with the already mentioned MIL-STD-810H resistance.

RAM is fixed at 4 GB LPDDR4X, paired with 128 or 256 GB of eMMC 5.1 storage, while the operating system is realme UI on top of Android 16. The phone unlocks with a reasonably fast and reliable side-mounted fingerprint reader integrated into the power button, along with facial recognition via the front camera.

Design, colors, and Pulse Light

The realme P4x features a body that recalls the proportions of vintage motorsport liveries. The unit tested, in Rally White, alternates a cream base with two diagonal stripes on the back, a dark one and a bright orange one, running from the camera module to the bottom edge. The other color available on the Italian market is Phantom Navy.

The back module houses the 50 Megapixel sensor, an additional dummy module, and the circular Pulse Light ring in a single elongated island: a composition that recalls the proportions of more expensive multi-camera systems, even though the actual photographic equipment consists of only one sensor.

The Pulse Light is the true distinctive element of the design and is exclusive to the European market. It is an LED ring that lights up to signal notifications, incoming calls, alarms, music playback, or battery status, with different colors depending on the event: it can change from white to violet to cyan, including more saturated colors like green and red.

From the Wallpaper and Style menu, it is possible to activate or deactivate the Pulse Light, set an active period, and customize the behavior for each individual event, from incoming calls to playing music. This granularity goes beyond a simple aesthetic gimmick and is a feature appreciated even in everyday use after the first few days.

The display hosts a drop-shaped notch, which is now rarely found on the latest models, paired with a more pronounced lower chin compared to other bezels: an aesthetic that aligns more with models from a few years ago than with the latest releases in the segment.

From our point of view, the vibration of the haptic motor is not very impactful and lacks materiality, far from the feedback of a more modern and defined response.

Software, hardware, and performance

The Unisoc T7250 octa-core SoC, combined with the Mali-G57 GPU, manages a device with 4 GB of LPDDR4X RAM and eMMC 5.1 storage in 128 or 256 GB variants. These specifications position the realme P4x in the most accessible segment of the market, far from 5G solutions and UFS storage adopted by competitors offered at a not overly different price.

In our tests, 3D Mark Wild Life scored 578 points, while Geekbench 6 recorded 436 points in single-core, 1,428 points in multi-core, and 707 points in the graphics test. Google Octane 2.0 reached 14,022 points, Speedometer 2.0 stopped at 48 runs per minute: numbers consistent with a chip designed for basic daily activities, not for intensive multitasking or demanding gaming.

Comparing with other devices in our benchmark database clarifies the positioning of realme P4x: the multi-core score of 1,428 points is among the lowest recorded so far, and the 578 points in 3D Mark Wild Life fall short of even 1,393 points from the realme C100, a model that competes in the same price range. Even the POCO M8, another low-cost competitor, easily surpasses it.

The CPDT test, dedicated to storage, measured 146 MB/s in sequential write, 187 MB/s in sequential read, and 3.46 GB/s in memory copy. These values surpass those of realme C100 (122 and 181 MB/s respectively in write and read), but remain typical of eMMC storage that is slower compared to the now-common UFS storage even in the mid-range.

In everyday use, perceived performance remains decent, aided by an interface that does not require excessive resources. The feeling changes when the device is pushed with heavier usage, prolonged multitasking, or more apps open simultaneously: in these cases, a general perception of slowness emerges, consistent with benchmarks that already indicate hardware designed for essential use.

The realme P4x arrives with realme UI built on Android 16. During the first boot, the setup allows you to choose which bloatware to install from the proposed apps: a commendable choice, although bloatware is not entirely eliminated even if all options are deselected. Undesired apps are added to promotional notifications of apps or services that occasionally appear in the interface.

The rest of the software provision follows the typical realme UI setup, with a set of features based on artificial intelligence now present even in the brand's more affordable models, from notification management to interface customization, here tailored according to the standards of a device aimed at the most accessible price segment.

Display and panel quality

The 6.8-inch LCD panel of realme P4x adopts HD+ resolution of 720 x 1,570 pixels, for a density of 254 PPI and a screen-to-body ratio of 90.4%. The maximum refresh rate reaches 120 Hz, with a touch sampling rate of up to 240 Hz, while protection is provided by Corning Gorilla Glass.

There are two color modes available, Vivid with 83% coverage of the DCI-P3 space and Natural with 100% of the sRGB space. realme claims a typical brightness of 700 nits, with a peak of 900 nits in HBM mode, but our measurements stopped lower: 592 nits with 15% area illuminated and 590 nits at full screen, values still sufficient for outdoor visibility in most conditions.

The density of 254 PPI becomes noticeable, especially on smaller text characters, where the pixel grid is visible up close: a compromise understandable given the price positioning, but it penalizes overall sharpness compared to more common Full HD+ panels in the same segment.

Battery life and charging

The 7,500 mAh battery represents the most evident strength of realme P4x. The device supports SUPERVOOC fast charging up to 45 W, compatible with VOOC, PPS, PD, and QC standards, in addition to reverse charging at 5 W to power other accessories. The package does not include a power adapter: besides the smartphone, the package includes a USB cable, SIM eject tool, manuals, and a protective case.

realme claims for the battery the proprietary Bionic Repair Technology, designed to maintain reliable performance over time, allowing over 1,600 full charge cycles before significant capacity drop.

In our battery tests, realme P4x achieved 1,380 minutes, over 23 hours, in the overall test: a result second only to the realme P4 Power, which with a 10,001 mAh battery stopped at 1,505 minutes, and superior to other devices with similar-sized batteries, such as the REDMAGIC 11S Pro (1,010 minutes) and HONOR Magic8 Lite (870 minutes). This confirms that the choice to sacrifice more powerful RAM and storage in favor of longevity pays off in numbers.

Overall test

Camera and image quality

The photographic component of realme P4x relies on a single 50 Megapixel rear sensor, f/1.8 aperture, 76-degree field of view, and 5-element autofocus, without ultra-wide-angle or optical stabilization. Video is limited to Full HD at 30 frames per second, without 4K mode.

The main sensor produces saturated colors and good overall performance. In wider shots, detail remains average for the segment, with dynamic range management that tends to slightly brighten the brighter areas of the sky. Color consistency between shots remains good, with a white balance that never drifts significantly towards warm or cool tones, even when changing scenes or lighting conditions.

The level of detail is good, although noticeable artifacts typical of marked post-processing are evident. As light decreases, perceived quality diminishes: noise increases and fine details disappear, with micromoss being always around the corner.

On the front, the 5 Megapixel sensor with f/2.2 aperture and 77-degree field of view manages selfies and video calls, limited to 720p resolution at 30 frames per second. The front camera provides sufficiently sharp selfies in good light conditions, with a natural skin tone reproduction, although the limited resolution becomes evident in more zoomed-in enlargements or subsequent crops.

Final considerations

The outcome of the review leans towards battery life, where realme P4x confirms itself as one of the most convincing battery phones in its range, thanks to a generous battery and fast charging that recovers energy in a short time. The more contained technical specifications, HD+ display, 4 GB RAM, and eMMC storage translate into a perception of slowness when the device is pushed beyond essential daily use.

The Pulse Light remains an aesthetic and functional feature that differentiates the model from competitors, although it does not fundamentally change daily use experience. For those looking primarily for a device that lasts all day and beyond, without worrying about a power outlet, realme P4x represents a solid choice in its price range, provided that the necessary compromises on display, memory, and performance are accepted.
