Vivo Y04 VS Xiaomi Redmi A5 4G

In terms of form factor, the Vivo Y04 is the more compact device overall. It is shorter (167.3 mm vs 171.7 mm), narrower (77 mm vs 77.8 mm), and occupies a meaningfully smaller volume (105.6 cm³ vs 110.9 cm³). This translates to a more pocket-friendly, easier-to-grip experience, particularly for users with smaller hands. The Redmi A5 4G, conversely, is fractionally thicker (8.3 mm vs 8.2 mm) but also slightly lighter at 193 g versus the Y04's 199 g — a 6-gram difference that is unlikely to be perceptible during everyday use.

The more significant differentiator in this category is the IP rating. The Vivo Y04 carries an IP64 certification, meaning it is fully dust-tight and protected against water splashes from any direction. The Redmi A5 4G, by contrast, is rated IP52 — offering only partial dust resistance and protection against low-pressure, vertically dripping water. In practice, the Y04 is considerably better suited to dusty environments and accidental splashes from unpredictable angles, giving it a clear edge for users who are rough on their devices or frequently use them outdoors.

Neither phone has a rugged build or a foldable form factor, so both target the same mainstream audience. However, the Vivo Y04 holds a meaningful advantage in this group: it is more compact and offers substantially stronger environmental protection through its superior IP rating, making it the more durable and ergonomically manageable choice of the two.

Both phones use an LCD IPS panel, so neither offers the deep blacks or vivid contrast of an AMOLED display — a common trade-off at this price tier. Where they genuinely diverge is in refresh rate: the Redmi A5 4G runs at 120Hz compared to the Vivo Y04's 90Hz. That 30Hz gap is tangible in everyday use — scrolling through social feeds, swiping between apps, and casual gaming all feel noticeably smoother on a 120Hz panel, even on an otherwise modest LCD screen.

Screen size and sharpness tell a more nuanced story. The Redmi A5 4G's display is marginally larger at 6.88″ versus 6.74″, but both panels land at an identical 260 ppi pixel density. This means neither phone has a sharpness advantage — the Redmi A5 simply scales its slightly higher resolution (720 x 1640 px vs 720 x 1600 px) to fill the larger screen, arriving at the same visual clarity. For media consumption, the larger canvas of the Redmi A5 4G is a minor but real benefit, while the Y04's smaller screen aligns with its more compact physical footprint noted in the design category.

Neither device supports HDR10, Dolby Vision, or Always-On Display, so premium content rendering and ambient information features are off the table for both. The Redmi A5 4G holds a clear edge in this group, driven entirely by its 120Hz refresh rate — the single most impactful display specification for perceived day-to-day fluidity at this segment.

The performance gap between these two devices is real and measurable. The Redmi A5 4G is powered by the Unisoc T7250, which scores 308,682 on AnTuTu, compared to the Vivo Y04's Unisoc T612 at 252,597 — roughly a 22% lead. In practical terms, this margin shows up in app launch times, multitasking responsiveness, and the ability to handle moderately demanding games without stuttering. Both chips are built on the same 12 nm process and share an identical 8-thread big.LITTLE architecture, so the difference is not architectural philosophy but raw silicon capability.

Memory is another area where the Redmi A5 4G pulls ahead. Its 6 GB of RAM versus the Y04's 4 GB means more apps can stay resident in the background without being killed — a meaningful quality-of-life difference for users who switch frequently between applications. The Redmi A5 4G also supports a higher maximum memory ceiling (12 GB vs 8 GB), offering more headroom for future software demands. On the GPU side, the Redmi A5 4G's Mali G57 doubles the shading units to 64 versus the Y04's 32, which directly benefits graphics rendering in games and UI compositing, despite both chips carrying the same number of GPU execution units. Both devices ship with identical 128 GB of internal storage and use eMMC 5.1 at the same RAM speed, so read/write performance is comparable.

Across every meaningful performance metric in this group, the Redmi A5 4G holds a clear advantage — more RAM, a higher benchmark score, and double the GPU shading units. The Vivo Y04's slightly faster efficiency cores are a negligible offset against this broader gap, making the Redmi A5 4G the stronger performer for users who prioritize snappy, sustained everyday performance.

The camera specs tell a decisive story here. The Redmi A5 4G packs a 32 MP main sensor with a wider f/1.8 aperture, against the Vivo Y04's 13 MP shooter at f/2.2. The resolution gap means the Redmi A5 4G captures significantly more detail — useful for cropping into shots without losing clarity. More importantly, the wider aperture lets in more light, which translates directly to better low-light performance: less noise, brighter exposures, and more usable photos in dim environments like indoor events or evening shots.

The selfie camera follows the same pattern. The Redmi A5 4G's 8 MP front camera edges out the Y04's 5 MP, and its slightly wider f/2.0 aperture (versus f/2.2) again offers a minor but real light-gathering advantage. For users who prioritize self-portraits or video calls, the Redmi A5 4G will consistently produce sharper, more detailed results. Both cameras cap video recording at 1080p at 30 fps, so neither has an edge in that department.

The feature sets are otherwise nearly identical — shared autofocus methods, HDR mode, manual controls, slow-motion, and panorama support appear on both devices. Neither shoots RAW or offers optical zoom, keeping both squarely in the entry-level tier. Still, within those constraints, the Redmi A5 4G holds a clear and meaningful camera advantage, with its higher-resolution sensor and brighter aperture on both front and rear making a tangible difference in real-world shooting conditions.

The software landscape between these two is largely uniform, with one meaningful distinction: the Redmi A5 4G ships with Android 15, while the Vivo Y04 launches on Android 14. A newer OS version at launch matters because it sets the baseline for how long the device will receive future updates before falling behind — starting one generation ahead gives the Redmi A5 4G a tangible longevity advantage out of the box.

The only other functional difference is app offloading, which the Redmi A5 4G supports and the Vivo Y04 does not. This feature allows the system to automatically remove rarely used apps while preserving their data, freeing up storage without requiring manual management. On a device with a fixed 128 GB of internal storage and no guaranteed expansion, this is a quietly useful capability. Beyond these two points, the feature sets are essentially identical — both offer dark mode, dynamic theming, split-screen multitasking, Picture-in-Picture, customizable notifications, and a solid suite of privacy controls including app tracking blocks and camera/microphone permission management.

Neither device receives direct OS updates, so long-term software support depends on the respective manufacturers' update policies rather than anything in this data. Within what the specs confirm, the Redmi A5 4G holds a modest but real edge — a newer Android version at launch and app offloading support combine to make it the slightly more future-ready choice in this category.

Battery life is where the Vivo Y04 reclaims ground lost in other categories. Its 5500 mAh cell outpaces the Redmi A5 4G's 5200 mAh by 300 mAh — a modest but not insignificant difference. At this capacity tier, that margin can translate to an extra 30–60 minutes of screen-on time depending on usage, which for a power user pushing through a long day without access to a charger is a genuine advantage. Both devices are already well-equipped for endurance by mainstream standards, but the Y04 nudges ahead.

Charging is a non-story: both phones top out at an identical 15W wired speed, ship with a charger in the box, and lack wireless charging entirely. The practical implication is that the Y04's larger battery will actually take slightly longer to fill from empty at the same wattage — a minor trade-off worth acknowledging. Neither phone offers a removable battery, which is now standard across this segment.

On balance, the Vivo Y04 holds a narrow edge in this category purely on capacity. The charging infrastructure is identical, so there is no offset from the Redmi A5 4G's side. For users who prioritize stretching through a full day on a single charge — particularly relevant given the Redmi A5 4G's more power-hungry 120Hz display — the Y04's larger battery provides a meaningful counterpoint to what it concedes elsewhere.

Audio is a category where the Vivo Y04 pulls ahead convincingly. Most notably, it features stereo speakers — something the Redmi A5 4G lacks entirely. The real-world impact of this is substantial: stereo output creates a wider, more immersive soundstage for media consumption, gaming, and video calls, while a single mono speaker on the Redmi A5 4G sounds comparatively flat and directional. For anyone who regularly watches videos or plays games without headphones, this is a meaningful quality-of-life difference.

The Y04 also includes a built-in FM radio, which the Redmi A5 4G omits. While radio is a niche feature for many users, it remains genuinely useful in areas with limited mobile data coverage or for users who prefer not to stream music. Both phones retain the 3.5 mm headphone jack — a welcome inclusion at this price tier that ensures compatibility with standard wired headphones without an adapter. Neither device supports high-resolution wireless audio codecs like LDAC or aptX Lossless, which is typical for this segment.

The Vivo Y04 wins this category outright. Stereo speakers alone would be enough to decide it, but the addition of FM radio makes the gap wider. For the Redmi A5 4G, the absence of stereo output is a notable omission — particularly given that its larger, higher-refresh display positions it as a media-friendly device on paper.

Connectivity is the most evenly matched category in this entire comparison. Both phones share an identical wireless feature set: dual-SIM support, Wi-Fi 5 (802.11ac), Bluetooth 5.2, USB Type-C with USB 2.0 speeds, a microSD card slot for expandable storage, GPS with Galileo support, and a fingerprint scanner. Neither device offers 5G, NFC, a gyroscope, or a compass — absences that are unremarkable at this price point but worth noting for users who rely on contactless payments or motion-sensitive applications.

The lone differentiator is cellular upload speed: the Redmi A5 4G supports up to 150 Mbits/s upload versus the Vivo Y04's 100 Mbits/s. In practice, this matters for users who frequently upload large files, stream live video, or back up data over mobile networks — the Redmi A5 4G will complete those tasks faster under ideal network conditions. For typical everyday use such as social media, messaging, and browsing, the gap is unlikely to be perceptible.

This group is effectively a near-tie, with the Redmi A5 4G holding a very slight technical edge through its higher upload ceiling. Neither phone distinguishes itself meaningfully in connectivity breadth or sensor suite — both are straightforwardly equipped for mainstream use without any standout additions or notable omissions beyond what is expected in this segment.

The miscellaneous spec sheet for these two devices is identical across every data point provided. Both feature a video light, and neither carries a sapphire glass display, a curved screen, or an e-paper panel — all of which are premium or niche features firmly outside the scope of this price tier.

This is an unambiguous tie. There is no differentiator in this category to analyze, and no advantage to assign to either device. The shared video light is a minor but practical feature, useful for recording in low-light conditions, and its presence on both phones simply confirms parity rather than giving either one an edge.
