Tecno Spark Go 2 VS Xiaomi Redmi A5 4G

Both the Tecno Spark Go 2 and the Xiaomi Redmi A5 4G share an identical 8.3 mm thickness and 77 mm width (the Redmi A5 is fractionally wider at 77.8 mm), making them virtually indistinguishable in hand from a slim-profile standpoint. However, the Redmi A5 is notably taller at 171.7 mm versus 165.6 mm for the Spark Go 2, resulting in a larger overall volume — 110.87 cm³ compared to 105.83 cm³. In practice, this means the Redmi A5 will feel slightly more elongated and may be less comfortable for users with smaller hands or those who prefer more compact devices.

The more meaningful differentiator in this group is water resistance. Both phones are rated as water resistant, but the Spark Go 2 holds a clear advantage with an IP64 rating, while the Redmi A5 carries only an IP52 rating. IP64 means the Spark Go 2 is fully dust-tight (the ″6″ digit) and protected against water splashing from any direction (the ″4″ digit). IP52, by contrast, offers only limited dust protection and guards against dripping water at a slight angle — a notably weaker standard. For users in dusty environments or who frequently use their phone near water, this distinction is practically significant.

Neither phone offers a rugged build or a foldable form factor, so they are evenly matched on those fronts. Overall, the Tecno Spark Go 2 holds a clear edge in this group: it is more compact and, more importantly, offers meaningfully stronger environmental protection with its IP64 rating compared to the Redmi A5's IP52.

At the panel level, these two phones are essentially identical in technology: both use an LCD IPS display, share a 120Hz refresh rate, and top out at 720p resolution. The 120Hz refresh rate is a genuine highlight at this price tier — scrolling and animations will feel noticeably smoother than on 60Hz budget devices, regardless of which phone you choose.

The main distinction comes down to screen size and pixel density. The Redmi A5 offers a larger 6.88-inch panel versus the Spark Go 2's 6.67-inch screen, which translates to more visible content area — useful for video consumption or reading. However, the larger screen comes with a marginal trade-off: at 260 ppi, the Redmi A5 is fractionally less sharp than the Spark Go 2's 263 ppi. In practice, the difference of just 3 ppi is imperceptible to the human eye, so sharpness is effectively a tie.

Neither display supports HDR10, Dolby Vision, or any branded damage-resistant glass, so there are no hidden advantages on either side. This group is largely a draw — the Redmi A5 edges ahead slightly if screen real estate is your priority, while the Spark Go 2's more compact display may suit users who prefer a smaller footprint without sacrificing any meaningful visual quality.

Under the hood, these two devices are powered by the exact same silicon — the Unisoc T7250 chipset with an identical 8-core CPU configuration, Mali G57 GPU, and a 12nm manufacturing process. The benchmark scores confirm this perfectly: both post identical Geekbench 6 results of 1461 multi-core and 437 single-core. There is zero daylight between them in raw processing or graphics performance.

Where the two diverge is in the memory and storage trade-off. The Redmi A5 ships with more RAM — 6GB versus the Spark Go 2's 4GB — which in practical terms means better multitasking headroom, fewer app reloads when switching between applications, and a generally smoother experience under sustained workloads. The Spark Go 2, however, flips the advantage on storage, offering 256GB of internal space compared to the Redmi A5's 128GB. For users who store large amounts of media, apps, or offline content locally, that doubling of storage is a tangible benefit.

Ultimately, this group comes down to a deliberate trade-off rather than one phone being outright superior. The Redmi A5 has the edge for day-to-day fluidity and multitasking thanks to its extra RAM, while the Spark Go 2 wins for users who prioritize onboard storage capacity. Buyers should weigh which resource — memory or space — matters more for their usage habits.

The headline difference in this group is the main camera resolution: the Redmi A5 sports a significantly higher 32 MP sensor compared to the Spark Go 2's 13 MP. With the same f/1.8 aperture on both, the Redmi A5's higher pixel count means more detail in well-lit shots and greater flexibility for cropping images without losing clarity — a meaningful advantage for users who care about photo quality.

Beyond resolution, the two cameras are remarkably alike. Both record video at 1080p at 30fps, lack optical image stabilization, and share an identical feature set covering HDR mode, phase-detection autofocus, continuous autofocus during recording, slow-motion, panoramas, and a full suite of manual controls. Front cameras are also matched at 8 MP on both devices. One minor note: the Spark Go 2 uses a dual LED flash versus the Redmi A5's single LED, which can mean slightly better flash illumination coverage in dark environments, though this is a secondary consideration.

On balance, the Redmi A5 holds a clear camera edge in this group, driven purely by its substantially higher main sensor resolution. The Spark Go 2's dual flash is a small consolation, but for users who prioritize photo detail and cropping flexibility, the Redmi A5's 32 MP shooter is the more capable option.

This is a rare case of a complete tie. Both the Tecno Spark Go 2 and the Xiaomi Redmi A5 4G run Android 15 and share an identical feature set across every single tracked specification in this group — without a single point of difference between them.

The shared software experience is fairly well-rounded for budget devices. Both offer meaningful privacy controls including location, camera, and microphone permissions alongside app tracking blocking. Daily usability features like dark mode, dynamic theming, split-screen multitasking, Picture-in-Picture, and customizable notifications are all present. On-device machine learning and offline voice recognition also make the cut, which is noteworthy at this tier.

The verdict here is straightforward: neither phone has any software advantage over the other. A buyer's decision cannot be influenced by operating system features — every capability and limitation listed applies equally to both devices.

Battery capacity is nearly identical between these two phones, with the Redmi A5 edging ahead at 5200 mAh versus the Spark Go 2's 5000 mAh. The 200 mAh difference is marginal — roughly a 4% gap — and in real-world use both phones should comfortably deliver all-day battery life under typical workloads. This is not a meaningful differentiator in practice.

Charging is a straight tie: both support 15W fast charging and both include a charger in the box. At 15W, neither phone will win any speed records, but it remains a functional standard that can replenish a significant portion of battery capacity within an hour. Neither device offers wireless charging, which is expected at this price segment.

Overall, this group is effectively a draw. The Redmi A5 holds a technically larger battery, but the margin is too slim to influence a purchase decision on its own. Charging speed, included accessories, and battery management are identical across both devices.

Audio specs are sparse on both devices, and largely shared. Neither phone offers stereo speakers, LDAC, or aptX Lossless — all expected omissions at this price tier — and both retain the increasingly rare 3.5mm headphone jack, which remains a genuine convenience for users who prefer wired audio without an adapter.

The only point of differentiation is the built-in FM radio, which the Spark Go 2 includes and the Redmi A5 does not. For users in areas with good FM coverage, or those who simply want offline, data-free audio access, this is a tangible real-world advantage — particularly in markets where FM radio remains a primary media source.

Given how closely matched these phones are elsewhere in audio, the Tecno Spark Go 2 takes the edge in this group solely by virtue of its FM radio inclusion. It is a modest but clear win for users who value that feature, while those indifferent to radio will find both phones functionally identical here.

Across most connectivity fundamentals, these two phones are evenly matched — both are 4G-only dual-SIM devices with USB Type-C, microSD expansion, a fingerprint scanner, GPS with Galileo support, and identical cellular download and upload speeds of 300 Mbps and 150 Mbps respectively. Neither includes NFC, which means mobile payments are off the table for both.

The sole but meaningful differentiator in this group is Wi-Fi. The Spark Go 2 is limited to Wi-Fi 4 (802.11n), while the Redmi A5 supports both Wi-Fi 4 and Wi-Fi 5 (802.11ac). Wi-Fi 5 operates on the 5GHz band and delivers significantly faster throughput and reduced congestion compared to Wi-Fi 4's 2.4GHz-primary approach. In practice, this means the Redmi A5 can take fuller advantage of modern routers and faster home broadband connections, with less interference in crowded wireless environments such as apartments or offices.

That Wi-Fi 5 advantage hands the Redmi A5 a clear edge in this group. It is not a dramatic gap, but for users who stream high-quality video, transfer large files over Wi-Fi, or simply want a more future-proof wireless connection, the Redmi A5 is the stronger choice here.

The Miscellaneous group offers no grounds for differentiation whatsoever. Every tracked spec in this category — the presence of a video light, the absence of sapphire glass, a curved display, and an e-paper display — is identical across both the Tecno Spark Go 2 and the Xiaomi Redmi A5 4G.

This is a complete tie, and the data in this group does not factor into any purchasing decision between the two devices.
