Oppo F21s Pro: In the fiercely competitive mid-range smartphone market, manufacturers increasingly seek to distinguish their offerings through specialized features or distinctive design approaches rather than attempting to excel across all aspects.
The Oppo F21s Pro exemplifies this focused strategy, delivering a device that combines striking aesthetics with capable everyday performance while placing particular emphasis on selfie photography and design refinement.
This targeted approach acknowledges that many consumers in this price segment prioritize style and specific use cases over raw performance metrics that might rarely prove relevant to their daily usage patterns.
Design Philosophy: Tactile Sophistication
The Oppo F21s Pro embraces a design language that balances visual distinctiveness with practical ergonomics. Most notable is the Fibreglass-Leather rear panel option—a material choice that provides both visual sophistication and practical advantages over typical glass or plastic alternatives.
This vegan leather implementation resists fingerprints while offering improved grip security, addressing two common complaints about contemporary smartphone designs while creating immediate visual distinction in a crowded market.
Available in Sunset Orange with the Fibreglass-Leather finish or Cosmic Black with a more conventional glossy surface, each variant creates a distinctive impression that reflects different user priorities.
The Sunset Orange option proves particularly successful, combining the textured leather-like material with a warm hue that shifts subtly under different lighting conditions.
This finish incorporates genuine fibreglass highlights around the camera module, creating a premium tactile experience that belies the device’s price positioning.
The frame employs a metal-like plastic construction with a matte finish that resists both fingerprints and scratches more effectively than chrome-effect alternatives often found in this segment.
At 7.54mm thick (7.66mm for the leather variant) and weighing approximately 175 grams, the F21s Pro trends toward the slimmer and lighter end of the current smartphone spectrum, enhancing comfort during extended use without feeling insubstantial.
The camera island adopts a minimalist rectangular housing with rounded corners, containing the lens array in a symmetrical arrangement that creates visual balance.
This housing rises minimally from the main body, reducing the “desk wobble” that plagues many contemporary smartphones when placed on flat surfaces.
The Orbit Light surrounding the microscope camera adds both functional utility and visual flair, illuminating close-up subjects while serving as a notification indicator.
The front face features relatively slim bezels with a slightly more pronounced chin, housing a punch-hole selfie camera in the upper left corner.
This asymmetrical placement represents a deliberate design choice that minimizes intrusion during landscape content consumption while maintaining sufficient distance from the edge for structural integrity.
Display Experience: Balanced Visibility
The centerpiece of the F21s Pro experience is its 6.43-inch AMOLED display, which combines appropriate specifications with excellent calibration. The 2400 × 1080 resolution provides approximately 409 pixels per inch—sufficient for crisp text and detailed media without excessive battery impact.
The 90Hz refresh rate delivers noticeably smoother scrolling and animations compared to 60Hz alternatives, while stopping short of the 120Hz implementations that often demand battery compromises at this price point.
Color reproduction impresses in the “Gentle” display mode, with Delta E values consistently below 3.0—sufficient for accurate representation of photos and videos without the excessive saturation that often characterizes displays in this segment.
The “Vivid” mode increases color intensity for those preferring more visual impact, though with the expected compromise in strict accuracy. The panel supports 100% DCI-P3 color gamut coverage, providing expansive color reproduction for compatible content.
Peak brightness reaches approximately 600 nits in high brightness mode, ensuring adequate visibility in most outdoor conditions while falling short of the 800+ nits achieved by premium alternatives.
The minimum brightness drops sufficiently low for comfortable nighttime viewing, while the DC dimming implementation eliminates the imperceptible flickering that can cause eye strain for sensitive users at lower brightness levels.
The in-display fingerprint sensor utilizes optical technology positioned relatively low on the screen for natural thumb placement.
This implementation demonstrates excellent recognition speed and reliability, particularly in good lighting conditions, though showing occasional hesitation in complete darkness—a common limitation of optical versus ultrasonic alternatives found in premium devices.
Performance Architecture: Everyday Reliability
At the heart of the F21s Pro lies the Qualcomm Snapdragon 680 chipset—a 6nm processor focused on efficiency rather than maximum performance.
This octa-core configuration combines four Kryo 265 Gold cores (based on Cortex-A73) running at 2.4GHz with four Kryo 265 Silver cores (based on Cortex-A53) at 1.9GHz, paired with the Adreno 610 GPU.
This hardware positioning places the device firmly in the mid-range category, prioritizing battery efficiency and thermal management over benchmark supremacy.
In practical usage, the F21s Pro handles everyday tasks with minimal hesitation—social media, messaging, video streaming, and casual photography all perform smoothly, while more demanding applications occasionally show brief loading delays that rarely impact overall satisfaction.
Memory management benefits from the generous 8GB RAM configuration, allowing a reasonable number of applications to remain in memory without aggressive background clearing.
The RAM expansion feature can allocate up to 5GB of storage as virtual RAM, providing additional headroom for multitasking scenarios. The 128GB storage proves sufficient for most users, with microSD expandability offering welcome flexibility for media-heavy usage patterns.
Gaming capability remains adequate for casual titles, which run without issue at medium to high settings. More demanding games like PUBG Mobile or Genshin Impact require reduced graphics settings to maintain acceptable framerates, revealing the processor’s positioning as an efficiency rather than performance-focused chip.
This approach aligns with the device’s target audience, who typically prioritize battery life and reliability over maximum gaming performance.
Thermal management proves particularly impressive, with the efficient processor and thoughtful internal design preventing noticeable external heating even during extended usage.
This characteristic enhances comfort during lengthy sessions while preserving battery efficiency that might otherwise be compromised by elevated temperatures.
Camera Capabilities: Specialized Photography
The camera implementation on the F21s Pro reflects Oppo’s focused approach, with particular emphasis on selfie performance and specialized capabilities rather than attempting to compete across all photography scenarios. The system consists of:
-
A 64MP primary sensor with f/1.7 aperture
-
A 2MP depth sensor for portrait effects
-
A 2MP microscope camera with 30x magnification and ring light
The primary camera delivers respectable results in favorable lighting, producing images with natural color reproduction, reasonable dynamic range, and good detail preservation.
The high resolution enables useful digital zoom up to about 2x magnification while maintaining acceptable quality. Low-light performance demonstrates expected limitations for this price category, with the night mode making appropriate compromises between noise reduction and detail retention.
The depth sensor provides useful data for portrait mode, enabling reasonably accurate subject separation for background blur effects. Edge detection proves generally reliable for human subjects in good lighting, though occasionally struggling with complex elements like hair or glasses in more challenging conditions.
The microscope camera represents perhaps the most distinctive photography feature, enabling extreme close-up imaging at 30x magnification.
This specialized lens allows exploration of textures and details invisible to the naked eye, creating genuinely novel photography opportunities rarely found on smartphones at any price point.
The surrounding Orbit Light provides essential illumination for these extreme close-ups, addressing the practical challenge of lighting subjects at such minimal focal distances.
The 32MP front-facing camera emerges as the genuine photography highlight, producing detailed selfies with natural skin tones and impressive dynamic range.
This implementation builds on Oppo’s long-standing emphasis on selfie performance, with sophisticated image processing that enhances results without creating the artificial appearance that often characterizes beauty modes.
The portrait mode effectively separates subjects from backgrounds using solely computational methods, while numerous creative filters provide engaging customization options.
Video capabilities include 1080p recording at 30fps from both front and rear cameras—a modest specification that nonetheless delivers stable, well-exposed footage suitable for social sharing.
The absence of optical stabilization results in some visible shake during movement, though electronic stabilization partially mitigates this limitation during relatively static recording.
Battery Life and Charging: Everyday Endurance
The F21s Pro houses a 4,500mAh battery that delivers impressive longevity, particularly considering the device’s slim profile.
Under typical usage patterns including social media browsing, messaging, occasional photography, and media consumption, the device consistently provides full-day battery life with 20-30% capacity remaining by bedtime.
More conservative usage can extend this to nearly two days between charges, while even camera-heavy days rarely deplete the battery before evening.
This endurance stems from both the substantial capacity and the efficiency-focused processor, which manages power consumption effectively across varied usage scenarios.
Charging capabilities include 33W SuperVOOC support, refilling the battery from empty to 50% in approximately 25 minutes and reaching full capacity in just under 65 minutes.
While not matching the extreme speeds of premium alternatives, this charging rate provides practical rapid replenishment that aligns well with typical usage patterns.
Battery health features demonstrate growing awareness of long-term usage concerns. The optimized night charging function learns sleep patterns to slow final charging phases, reducing battery stress during overnight charging.
The battery health management system monitors temperature and charging patterns to preserve capacity over the device’s lifespan—an increasingly important consideration as consumers extend their smartphone replacement cycles.
