Review of realme 16 5G: The smartphone with Selfie Mirror features a 6550mAh battery

realme 16 5G

The realme 16 5G arrives on the market with three specific points: a camera system that bears the Sony signature on the main sensor, a novel physical mirror integrated into the camera bar for selfies with the rear camera, and a 6550mAh battery packed into a chassis just 8.1mm thick thanks to AirCraft Structure technology. Additionally, it boasts an IP69K certification that exceeds the common IP68 standard found in the mid-range segment.

The system runs on MediaTek Dimensity 6400 Turbo with realme UI 7.0 and the new Flux Engine. The official price is below 400 euros, with further discounts expected during the launch period, positioning it in the competitive mid-range segment.

Technical Specifications

The realme 16 5G presents a compact form factor despite its generous battery: 158.30x75.13x8.10 mm for around 183 grams. The chosen chipset is the MediaTek Dimensity 6400 Turbo, an octa-core at 6nm with a Mali G57 MC2 GPU, providing solid performance in mainstream gaming and everyday multitasking without excessive heat.

The display is a 6.57-inch AMOLED with FullHD+ resolution (2372x1080 pixels), a density of 397 PPI, refresh rates up to 120Hz, and default touch sampling that operates at 120Hz with peaks of 240Hz. Technically, it reproduces 1.07 billion colors with 100% DCI-P3 color coverage in Vivid, Cinematic, and Colorful modes, while the Natural mode adheres to 100% sRGB. The protective glass is a DT Star D+.

In terms of photography, the rear sensor is a 50MP Sony IMX 852 with an f/1.8 aperture, 75° FOV, and autofocus. This sensor is shared with the 16 Pro series. The front camera is also 50MP with f/2.4 and 86° FOV. Unlike what one might think when observing the rear module, there is no telephoto or ultra-wide angle: the system consists of a single rear sensor plus the front one, featuring the differentiating element of the integrated physical selfie mirror in the camera bar.

The battery is, on paper, the highlight of this smartphone: we are talking about a 6550mAh unit, supporting 45W fast charging in PPS mode. It also features bypass charging and reverse charging to other devices, which are also quite interesting at this price range.

Connectivity includes 5G sub-6GHz, Wi-Fi 5 (802.11ac), Bluetooth 5.3 with Low Energy, and comprehensive LTE FDD and TDD coverage. The operating system is realme UI 7.0 based on Android, while the available memory versions include combinations of 6GB and 8GB of RAM, with storage options of 128GB and 256GB. In Italy, it comes with both RAM configurations, but only in the 256 GB version of built-in storage.

Design

The most evident stylistic choice on the realme 16 5G is the horizontal camera bar on the back, a module that extends in width integrating, for the first time in the industry (according to realme), a physical mirror for selfies placed at the extreme right of the bar. The practical advantage is immediate: using the rear camera in selfie mode, the user can frame themselves by looking directly at the small mirror instead of relying solely on the preview on the screen. The module has a slightly convex profile that keeps the center of gravity stable when the phone is placed on a flat surface, avoiding the classic rocking effect seen on some competitors with prominent camera islands.

The Aurora Wings white coloring best represents realme's investment in aesthetics: the rear glass casing with fine-sand texture adopts a triple particle plating process that overlays gold, blue, and glitter in distinct layers, creating a chameleon effect that changes appearance with varying light angles. The anti-fingerprint treatment reduces mark retention during everyday use.

The darker coloring (Graphite Black, the one we tested) adopts a uniform matte finish without visible texture, is more subdued, and perhaps less tiring in the long run. The bezels around the display are very minimal for a smartphone in this price range, with the bottom measuring just over 2mm, contributing to a 93% screen-to-body ratio. The edges are rounded to facilitate one-handed grip, resulting in an excellent ergonomics despite the large integrated battery.

For this purpose, the weight of 183 grams helps, a direct merit—according to realme—of the internally developed AirCraft Structure construction technology: a high-density component layout minimizes empty spaces inside, freeing up volume for more compact and simultaneously larger high-energy cells. Notably, the battery is not silicon-carbon.

User Experience, Hardware, and Performance

The smartphone runs from the first start with realme UI 7.0 and adopts the Flux Engine, representing realme's attempt to create a system-level optimization engine (not just software). The architecture is divided into three modules: Flux Animation Framework (the first realme native animation framework), Flux Scheduling Algorithm (Dynamic Frame Generation at the chip level), and Flux Booster (editing architecture that enables cross-tier data fusion). The stated numbers are +15% in daily response, +29% smoother scrolling, and +22% app loading for heavy apps compared to the previous version.

In practice, the smartphone always appears ready for use, with virtually no waiting times for the end user. The fluidity is solid, provided one does not use heavy apps or games from the Play Store, with a remarkably high user experience that is no longer that rare in this market segment.

Visually, the interface has undergone a restyling with Cube icons, Misty Glass-style Control Center, new animated wallpapers, and redesigned fingerprint sensor animations. The engine also introduces three specific types of animation: Continuous Startup Animation for sequential app launches, Snake Style Animation for reorganizing icons, and Quick Switch Animation for rapid task switching.

The heart of the photography and editorial experience is the AI Edit Genie suite, which introduces tools that have become common among Android devices. Among these stands out AI Inspiration, a feature capable of analyzing gallery shots to apply targeted and automatic improvements with a single click. AI StyleMe allows one to transform portraits by applying three-dimensional creative filters (like Cartoon Shot and 3D Modeling), while AI LightMe simulates studio lighting schemes, from party neon to beams of light like windows, directly in post-production.

Completing the package aimed at content creators is AI Instant Clip (only for the versions with 8GB of RAM), a function that instantly transforms photos, videos, and Motion Photos into ready-made VLOGs for social media, complete with automatic editing, subtitles, and speed management.

The AI optimization does not stop with images: thanks to the Al Battery Boost Engine and predictive energy management algorithms, the system learns the user’s habits to regulate the charge current and preserve battery health over the long term. The entire system is powered by the Dimensity 6400 Turbo chip, built on a 6nm process, which does not aim for record benchmarks but rather maximum thermal stability during prolonged gaming and streaming sessions.

Display

The 6.57-inch AMOLED panel with FullHD+ resolution is the expected combination in this range, but the brightness numbers clearly distinguish it from direct competition.

realme states 1000 nits typical brightness under normal operation, HBM (High Brightness Mode, automatically activated outdoors in bright sunlight) at 1400 nits, while the absolute peak reaches 4200 nits: a rare value, but not unique, below the 300-400 euro mark, ensuring uncompromised readability even in the middle of summer sunshine.

The 10-bit color depth with 1.07 billion shades, combined with the 100% DCI-P3 coverage, makes the display suitable for watching HDR content. Default touch sampling at 120Hz (with peaks at 240Hz on request) responds well to gaming and quick scrolling on social media.

The DT Star D+ glass is not the latest generation Gorilla Glass but offers adequate scratch resistance for everyday use. The smartphone is also packaged with a pre-applied protective film, which performed particularly well in our tests against common wear and scratches.

With a 93% screen-to-body ratio and a lower bezel measuring 2.23mm, it contributes to a borderless visual experience, also a pleasant feature to achieve at this price range.

Battery Life

The 6550mAh battery is the strongest feature of the realme 16 5G, not only for its absolute capacity. The smartphone offers around a day and a half of real usage—even moderately—inside a device that weighs significantly less than the all-important 200 grams.

Data provided by realme indicate 45.14 hours of standby with the screen on, 10.80 hours of MLBB at max graphics, 26.83 hours of Instagram scrolling, and 21.84 hours of WhatsApp chatting at 350 nits, plus 118.05 hours of music playback via Spotify with wired earphones at volume level 10.

Our overall test, performed with display brightness set at 200 nits and a script simulating human interactions on web pages, video streaming, and alternating sessions of CPU and GPU benchmarks, concluded in 855 minutes, a result that places the smartphone in the mid-high range of the entire category.

Camera

The camera system on the realme 16 5G focuses entirely on the 50+50MP duo (front and rear) as a unique offering in this price segment. No direct competitor, according to realme, provides both a 50MP front sensor and a 50MP Sony IMX 852 at the back concurrently; however, the setup lacks versatility as it offers neither an ultra-wide angle nor a telephoto lens.

The photography software is called LumaColor IMAGE and shares the same algorithms as the 16 Pro series: this includes the AI Color & Portrait Algorithm for managing skin tones and distortion, the Imaging RawHDR Algorithm for managing lights and shadows, and the AI Facial Feature Beautification Algorithm with ethnic recognition to optimize face shape, hairline, and cheekbones consistent with the subject’s physiological characteristics.

Rear Wide-angle: 50MP Sony IMX 852 sensor, f/1.8, FOV 75°, autofocus supported. The sensor has physical dimensions of 1/2.93”, which represents a decent size for light collection in the mid-range.

Video Features: Rear videos cover 1080p at 30 and 60fps, 1080p with EIS/OIS, slow motion 720p at 120fps, Cinematic mode at 30fps, and even a dedicated 1080p UNDERWATER mode coherent with the smartphone's IP69K certification. Video zoom and dual-view shooting are supported for simultaneous front and rear captures.

The combination with the integrated physical Selfie Mirror in the camera bar is the real novelty: by observing the small circular mirror while pointing the rear camera towards oneself, one can check the composition in real-time before taking a shot. This way, we can create self-portraits with the best sensor present in the smartphone, avoiding "blind" shots which often lead to out-of-focus or poorly framed photos.

Front Camera: 50MP, f/2.4, FOV 86°. The wide field of view makes it suitable for group selfies. It lacks autofocus. Quality is good, both in managing light and shadow, and especially in the high detail captured. The algorithms in Portrait mode also perform decently, managing hair and fine details quite credibly (though somewhat aggressively).

The integrated Vibe Master Mode technology adds 20 preset ambient light tones with three main presets (Lively, Festival, Ceremony), accessible by scrolling down the shutter button. The Aura Flash, the circular flash integrated into the rear camera bar, aims to distribute more uniform light compared to classic single-point flashes, particularly useful for group selfies.

Price

The smartphone is sold in two different memory and storage variants, both available in Air White and Air Black colors. It is important to emphasize that the sample currently distributed for reviews in the specialized press features a top configuration of 8+512GB; however, this specific version will not be marketed in our country, where the range will focus instead on the 256GB versions.

Regarding in-store availability, the entry-level version of 6+256GB is an Amazon exclusive. Those aiming for the higher configuration of 8+256GB can purchase it through major national consumer electronics chains, including Unieuro, Mediaworld, Euronics, Trony, and Expert. To celebrate the launch, both channels will offer a special launch promotion valid until June 24, allowing the purchase of the device at a discount from the official list price. After the promotional period, products will be offered at their standard list price. Below are the details of the prices and promotions for Italy:

• 6+256GB Variant (Amazon Exclusive):
  • List price: €379.99
  • Launch promotional price (valid until 24.06): €359.99
• 8+256GB Variant (Available at Unieuro, Mediaworld, Euronics, Trony, Expert):
  • List price: €399.99
  • Launch promotional price (valid until 24.06): €379.99

Final Considerations

The realme 16 5G builds its identity on concrete and measurable elements: a large battery in a thin chassis, a water resistance certification that exceeds the IP68 category, a Sony sensor on the back in a segment that usually features less refined sensors, and a physical mirror in the camera bar that allows for selfies with high-quality camera.

The Flux Engine and the 72 months of guaranteed fluidity are medium-to-long-term promises that can only be verified over time, but the premises seem to be of excellent quality based on our test which lasted several days. Battery life is also at an excellent level, with this characteristic representing—along with the device's lightweight—the main reason for purchasing this smartphone.

The main limitations are equally clear: no ultra-wide angle, no telephoto, Wi-Fi 5 instead of Wi-Fi 6 (a shortcoming that starts to weigh in 2026), and a Mali G57 MC2 GPU that is not the optimal choice for those playing demanding titles at high settings.

So, for whom is this realme 16 5G? For those seeking a smartphone to keep for three or four years, with battery life lasting a full day, a chassis resistant to hot, high-pressure water, and high-quality main camera, this realme 16 5G presents a serious candidate. However, those who desire full photographic versatility will need to look elsewhere (though spending a bit more).
