realme P3 Ultra

The realme P3 Ultra is a performance-oriented 5G smartphone from realme's P series. It combines a MediaTek Dimensity 8350 Ultra chipset, 12GB of LPDDR5X RAM, a 6.83-inch quad-curved AMOLED screen, a 6,000 mAh battery with 80W wired charging and an IP69 rating in a body that is only 7.38 mm thick. This page is based on the published specifications and manufacturer information from realme's global product and specification pages, and it marks realme's statements as claims, because many figures on those pages come from realme Lab tests rather than from independent measurements.

Place in the lineup

The P series is realme's performance-for-the-money line, and realme's website lists the P3 Ultra 5G alongside the P3 5G and the P3 Lite. realme's pitch for the Ultra is a high-end chipset, a curved display and very fast charging in a slim body. The page does not give a price or a launch date, so neither is stated here; the date used (19 March 2025) comes from the editorial plan for this entry and should be treated as approximate. For context in the same company's catalogue, the realme 15, the realme 14T and the newer realme 16 Pro+ sit in different price tiers, and a realme P3 Ultra vs. realme 15 comparison shows how the chipset and screen differ between generations.

Design and display

The design is built around what realme calls the Lunar Design: the white version, Glowing Lunar White, has a moon-themed pattern that realme says glows in the dark (and that, according to a footnote, may vary with the environment and test conditions). The second colour is Neptune Blue. The Lunar White model measures 163.10 x 76.90 x 7.38 mm and weighs about 183 g, while the Neptune Blue version is slightly thicker and heavier at 7.47 mm and about 186 g, according to the specification page, which also mentions a leather version and a plate version. realme says the 7.38 mm thickness made it the thinnest body among smartphones in its price range at the time of launch, which is a claim about the phone's own segment and not an absolute statement. The phone carries an IP69 rating, together with IP68 and IP66, which means that realme states resistance to submersion, hot water and high-pressure jets; the company adds the usual warning not to deliberately immerse the phone in daily use and notes that the protection can decrease over time.

The screen is a 6.83-inch AMOLED panel with a resolution of 2800 x 1272 pixels, a refresh rate of up to 120Hz and a quad-curved shape, which means that all four edges curve. realme lists a peak brightness of 1500 nits, a contrast ratio of 5,000,000:1, 1.07 billion colours and 100 percent DCI-P3 coverage, PWM dimming at 3840Hz for eye comfort and TÜV Rheinland low-blue-light certification. The bezels are 1.6 mm thin and the screen-to-body ratio is 93.8 percent. Protection comes from 0.55 mm Gorilla Glass 7i. Touch sampling is up to 240Hz on the specification page, and realme's gaming section advertises a touch response of up to 2500Hz in an instant-touch mode. Curved edges look elegant and make the phone comfortable to hold, but they can also cause accidental touches, which realme says its software reduces, and they make screen protectors harder to fit.

Performance, memory and software

The processor is the MediaTek Dimensity 8350 Ultra, built on a 4nm process with an octa-core CPU of up to 3.35GHz, a Mali-G615 GPU and an NPU 780 for AI tasks. realme states an AnTuTu score of more than 1,450,000, and it claims a steady 120 frames per second in several popular games until the battery runs out. Those figures come from realme Lab, but they place the chip in the upper-middle class, well above the entry-level hardware that most phones in this price range use. The RAM is 12GB of LPDDR5X with a data rate of up to 8533 Mbps, and storage options are 256GB or 512GB; realme also offers up to 14GB of dynamic RAM expansion, which borrows storage space and should be seen as a convenience rather than real memory.

Thermals are handled by a 6050 mm² vapour-chamber cooling system that realme describes as aerospace-grade, and the company claims it lowers the maximum CPU temperature by 19 degrees Celsius compared with a reference. realme also lists GT Boost game optimisation, a geek power-tuning mode, an X-axis linear vibration motor and dual stereo speakers with Hi-Res audio certification. The software is realme UI 6.0 based on Android 15, and the product page highlights AI features such as Circle to Search, Google Gemini, an AI writer, recording summaries and a smart loop for efficiency. The page does not state how many Android upgrades or years of security updates realme promises, so that is worth checking separately if long-term support matters to you.

Camera

The rear camera has two lenses. The main one is a 50MP Sony IMX896 sensor with optical image stabilisation, an f/1.8 aperture, a 24mm-equivalent focal length and a resolution of 4096 x 3072 for photos, and the second is an 8MP ultrawide camera with a 112-degree field of view and an f/2.2 aperture. There is no telephoto lens and no dedicated macro lens. The front camera is a 16MP Sony sensor with an f/2.4 aperture. Video can be recorded in 4K at up to 60 frames per second on the rear camera, with stabilisation, slow motion at 720p up to 240 frames per second and a dual-view mode.

realme puts the emphasis on AI editing: AI Clear Face and AI Unblur for sharpening portraits, an AI Eraser for removing distractions and AI LivePhoto in 2K. These tools work after the shot, so the final quality depends on the software and on the original image. Two cameras are fewer than the three or four that some rivals list, but the stabilised main sensor is the part that determines most everyday results, and 4K at 60 frames per second is a better video specification than many phones in this class offer.

Battery and charging

The battery is a 6,000 mAh cell (typical value; the rated capacity is 5,860 mAh), which realme calls the Titan battery and which it built with C-Pack technology reinforced by graphite to keep the body slim. Charging is by 80W SUPERVOOC through USB Type-C, and an 80W adapter is included in the box, which is a point in its favour at a time when many brands have dropped the charger. realme claims a full charge from 1 to 100 percent in 47 minutes and that five minutes of charging provide about 1.8 hours of online meetings. It also claims up to 17 hours of video playback and a 10-hour gaming session, as well as a battery that stays healthy for five years of gameplay. The phone supports bypass charging, which powers the system directly from the charger while gaming, and realme says this lowers the temperature by 2.2 degrees Celsius. All of these numbers are from realme's own tests.

Connectivity and extras

The P3 Ultra supports 5G in both standalone and non-standalone modes, with a long list of 5G, LTE, WCDMA and GSM bands, dual nano-SIM slots, Wi-Fi 6, Bluetooth 5.4 (with an upgrade to Bluetooth 6.0 promised by a future OTA update), NFC and a full set of satellite navigation systems. There is an in-display fingerprint sensor and an infrared emitter, and the sound system uses two speakers with dual-microphone noise cancellation. There is no microSD slot listed. The box contains the phone, a USB Type-C cable, the 80W adapter, a protective case, a SIM tool and the guides.

Who it is for

The P3 Ultra suits users who want strong performance, a bright and smooth screen and very fast charging without paying flagship prices: mobile gamers, heavy multitaskers, and people who value a slim body with a big battery. It also suits buyers who like a distinctive design, since the Lunar White finish with its glow-in-the-dark effect is more unusual than the plain colours of most competitors.

Compromises

• Two rear cameras only: there is no telephoto or macro lens, so zoom relies on cropping the 50MP sensor.
• Curved screen: quad-curved edges are attractive but can cause accidental touches and complicate protectors.
• Update promise not stated: the pages do not give the number of Android upgrades or security-update years.
• Company-sourced figures: benchmarks, thermal data and battery life come from realme Lab, so independent tests should confirm them.
• Heavier in blue: the Neptune Blue version is 7.47 mm thick and about 186 g, slightly more than the white one.

Overall, the realme P3 Ultra is a feature-rich performance phone whose main strengths are the Dimensity 8350 Ultra, the 80W charger in the box and the slim, water-resistant body. To see how it compares with other models in the database, open the rankings page.
