Both the Realme C75 5G and the Xiaomi Redmi A5 4G are water-resistant and share a conventional, non-folding form factor, so neither has a rugged build designation. That said, the Realme holds a meaningful edge in protection: its IP64 rating guards against dust ingress entirely and resists water splashes from any direction, while the Redmi A5's IP52 rating offers only limited dust protection and resistance to light, low-pressure water drips. In everyday use, this difference matters — IP64 is noticeably more reassuring in rain, near sinks, or in dusty environments.

On physical dimensions, the Realme C75 5G is the more compact and pocketable device across every measurement. It is 0.4 mm thinner (7.9 mm vs 8.3 mm), narrower, and shorter, resulting in a significantly smaller overall volume — 99.75 cm³ versus 110.87 cm³ for the Redmi A5. That roughly 10% volume difference is perceptible in hand and in a pocket. The weight gap is negligible at just 3 g (190 g vs 193 g), so that alone would not influence a choice.

In this category, the Realme C75 5G has a clear advantage: it is slimmer, more compact, and offers superior ingress protection. For users who prioritize a sleeker profile and better resistance to dust and water, the Realme is the stronger choice based strictly on these design specs.

Display:
Display type LCD, IPS LCD, IPS
screen size 6.67" 6.88"

These two displays share the same panel technology (LCD IPS), resolution tier (720p), refresh rate (120Hz), contrast ratio (1500:1), and lack of any HDR support — so at a glance, they appear nearly identical. The practical image quality difference between them will be imperceptible to most users, since the pixel density gap is just 4 ppi (264 ppi on the Realme C75 5G vs 260 ppi on the Redmi A5). Neither screen will render text or images with the sharpness of a 1080p panel, but both are adequate for everyday content consumption at typical viewing distances.

Where the two diverge is screen size and touch responsiveness. The Redmi A5 offers a larger 6.88″ panel versus 6.67″ on the Realme — a difference that benefits media viewing and reading. However, the Realme counters with a slightly higher pixel density as a consequence of fitting the same resolution into a smaller screen. On touch sampling, the Redmi A5 edges ahead with 240Hz versus the Realme's 180Hz, meaning it polls touch inputs more frequently — a subtle but real advantage for fast scrolling and casual gaming responsiveness.

This category is essentially a trade-off rather than a clean win for either side. Users who prioritize a larger viewing area will lean toward the Redmi A5, while those who want marginally crisper visuals in a smaller footprint may prefer the Realme. Neither product holds a decisive overall display advantage based on these specs alone.

The silicon gap here is substantial. The Realme C75 5G runs on the MediaTek Dimensity 6300, built on a modern 6 nm process, while the Redmi A5 uses the Unisoc T7250 on an older 12 nm node. A smaller manufacturing process generally translates to better power efficiency and thermal performance — meaning the Realme can sustain workloads longer without throttling and with less battery drain. The CPU clock speeds reinforce this: the Realme's cores run at up to 2.4 GHz versus the Redmi A5's 1.8 GHz peak, a gap that compounds under sustained load.

Benchmark results make the real-world difference concrete. The Realme C75 5G scores 782 single-core and 2012 multi-core on Geekbench 6, compared to 437 single-core and 1461 multi-core for the Redmi A5. The single-core gap — nearly double — matters most for everyday responsiveness: app launches, UI animations, and general snappiness. The Realme also carries 8 GB of RAM (vs 6 GB) at a faster 2133 MHz speed, and doubles the L3 cache to 2 MB, both of which reduce latency when switching between apps or handling memory-intensive tasks. GPU clock speed similarly favors the Realme at 950 MHz versus 850 MHz.

The Realme C75 5G holds a clear and comprehensive performance advantage in this category. Across chipset architecture, process node, CPU speed, benchmark scores, RAM capacity, and cache size, it outpaces the Redmi A5 at every level. Users who care about smooth multitasking, gaming, or simply a phone that stays responsive over time will find the Realme the stronger performer by a significant margin.

Rarely does a comparison yield a result this definitive: the camera specifications for the Realme C75 5G and the Xiaomi Redmi A5 4G are identical across every single data point provided. Both shoot with a 32 MP main sensor at f/1.8, pair it with an 8 MP front camera at f/2, cap video at 1080p 30fps, and share the same autofocus system — phase-detection for stills and continuous autofocus during video. Neither offers optical image stabilization, optical zoom, or a multi-lens setup.

The manual controls available on both — ISO, exposure, focus, and white balance — give users a reasonable degree of creative control for a budget-tier device, though the absence of manual shutter speed limits low-light flexibility. Slow-motion and panorama support round out a feature set that is functional without being remarkable. The lack of a BSI sensor on either device is a minor note: BSI sensors typically improve low-light performance, so both phones share the same constraint there.

This category is an absolute tie. There is no basis in the provided specs to differentiate the two phones on camera capability — every hardware spec and feature flag is a mirror image. A buyer for whom camera quality is the deciding factor will need to look beyond this specification group entirely.

Much like the camera group, the operating system specs present a perfect mirror between the two devices. Both the Realme C75 5G and the Xiaomi Redmi A5 4G launch on Android 15 and share an identical feature set across every tracked data point — from privacy controls (location, camera/microphone access, app tracking blockers) to usability features like dark mode, dynamic theming, split-screen, and Picture-in-Picture. Neither device receives direct OS updates, and neither supports focus modes, cross-site tracking blocking, or Wi-Fi password sharing.

The privacy and productivity foundations shared by both are genuinely solid for the budget segment. On-device machine learning, offline voice recognition, customizable notifications, and a media picker are all present — features that were once mid-range exclusives. The absence of direct OS updates on either device is worth noting: it means both rely on manufacturer-pushed updates, which can be slower and less consistent than stock Android guarantees.

This is a complete tie. Every OS feature and privacy flag is identical across both phones. Software experience will ultimately be shaped by each manufacturer's custom Android skin rather than the underlying Android version or feature set — a distinction that falls outside the scope of the provided data.

Battery:
battery power 6000 mAh 5200 mAh
has wireless charging
Supports fast charging
charging speed 45W 15W
comes with a charger
has a removable battery
has a battery level indicator
has a rechargeable battery

After several tied categories, battery is where the Realme C75 5G pulls ahead decisively. Its 6000 mAh cell is a meaningful step up over the Redmi A5's 5200 mAh — an 800 mAh difference that, in practice, can translate to several additional hours of screen-on time depending on usage patterns. For users who spend long days away from a charger, that gap is tangible rather than theoretical.

The charging speed difference is even more striking. The Realme supports 45W fast charging versus just 15W on the Redmi A5 — a three-fold advantage. A larger battery that also refills far faster is a rare combination at this price tier. In real-world terms, the Realme can go from low battery to a substantial charge in a fraction of the time the Redmi A5 would require. Both phones come with a charger in the box, which is worth noting as it is no longer universal across the industry.

The Realme C75 5G wins this category outright. It offers more capacity and dramatically faster replenishment, making it the superior choice for battery-conscious users on both fronts simultaneously. The Redmi A5 has no compensating advantage here based on the provided specs.

Audio:
has a socket for a 3.5 mm audio jack
has stereo speakers
has LDAC
has aptX Lossless

The audio specs for both the Realme C75 5G and the Xiaomi Redmi A5 4G are identical and minimal. Each device includes a 3.5 mm headphone jack — a welcome inclusion at this price point, where many users rely on wired earphones rather than wireless accessories. Neither phone supports stereo speakers, high-resolution Bluetooth codecs like LDAC, or aptX Lossless, keeping the audio profile firmly utilitarian.

The absence of stereo speakers means both devices produce mono sound from a single driver, which limits the immersiveness of media playback compared to dual-speaker setups. For casual listening through the built-in speaker, both phones will perform equivalently — and modestly. The headphone jack partially compensates: wired listening remains the most reliable path to decent audio quality on budget hardware, and both phones accommodate it without requiring an adapter.

This category is a tie in every respect. Neither device offers an audio advantage over the other, and audio-focused buyers should factor in the shared limitations — particularly the mono speaker output — when evaluating either phone.

Connectivity is where the gap between these two phones widens most dramatically. The Realme C75 5G supports 5G, which the Redmi A5 does not — and the downstream speed figures underscore just how significant that is: the Realme is capable of up to 3300 Mbits/s download versus only 300 Mbits/s on the Redmi A5's 4G ceiling. For users in areas with 5G coverage, this translates to a fundamentally different mobile data experience in terms of speed and future-proofing. Beyond cellular, the Realme also includes NFC — enabling contactless payments and quick device pairing — while the Redmi A5 omits it entirely. The Realme further adds a digital compass, useful for navigation apps, which the Redmi A5 lacks.

Where the two converge, they are well-matched for the budget tier: both offer dual SIM slots, expandable storage, USB Type-C (USB 2.0), identical Wi-Fi support (Wi-Fi 4 and Wi-Fi 5), fingerprint scanners, GPS with Galileo support, and accelerometers. Bluetooth favors the Realme marginally at version 5.3 versus 5.2 on the Redmi A5, though the practical difference in everyday use is negligible.

The Realme C75 5G holds a clear and multi-faceted advantage in this category. The combination of 5G connectivity, NFC, and a compass versus a 4G-only device without either feature makes the Realme the stronger choice for users who want a more capable and future-ready connectivity profile.

Miscellaneous:
has a video light
Has sapphire glass display
Has a curved display
Has an e-paper display

The miscellaneous specs for the Realme C75 5G and the Xiaomi Redmi A5 4G are identical across every available data point. Both feature a video light — essentially a torch that stays on during video recording to illuminate subjects in low-light conditions — and neither carries a curved display, sapphire glass, or an e-paper screen. All of these absences are entirely expected for devices in this price segment.

This is a complete tie with no differentiating factors present. The data set for this category is narrow, and none of the tracked attributes create any meaningful distinction between the two phones. Buyers will find no reason to choose one over the other based on these miscellaneous specs alone.

Comparison Summary & Verdict

After examining every specification, a clear picture emerges for each device. The Realme C75 5G stands out as the stronger all-around performer, offering a faster MediaTek Dimensity 6300 chipset built on a 6nm process, more RAM, a larger 6000 mAh battery with 45W fast charging, and crucially, 5G connectivity and NFC — features that future-proof the handset considerably. It is the better choice for users who prioritize raw performance, faster top-ups, and modern network support. The Xiaomi Redmi A5 4G, on the other hand, appeals to buyers who want a larger 6.88-inch screen and a higher 240Hz touch sampling rate in a no-frills 4G package. It is a sensible pick for light users in areas where 5G is not yet available and who are less concerned with charging speed or processing power.
