Tecno Camon 40 Pro 4G VS Vivo Y400 Pro 5G

The most significant design differentiator here is water protection. The Tecno Camon 40 Pro 4G carries an IP68 rating, meaning it is certified to withstand full submersion in water — a meaningful real-world advantage for accidental drops in sinks, pools, or rain. The Vivo Y400 Pro 5G, by contrast, holds an IP65 rating, which covers dust ingress and resistance to water jets, but offers no protection against submersion. For users who want genuine peace of mind around water, this gap is not trivial.

In terms of physical form, both phones are very close, but the Camon 40 Pro 4G edges ahead on compactness. At 7.3 mm thick and 178 g, it is noticeably slimmer and slightly lighter than the Y400 Pro 5G's 7.7 mm profile and 182 g frame. The volume difference — roughly 89.5 cm³ vs 94.6 cm³ — confirms the Camon occupies meaningfully less physical space, translating to a slightly more pocket-friendly, premium feel in hand. The height and width of both devices are nearly identical, so the slimness and weight savings are the real tactile story.

Neither phone has a rugged build or a foldable form factor, so both target the mainstream flat-slab market. Overall, the Tecno Camon 40 Pro 4G holds a clear design edge: it is slimmer, lighter, and — most importantly — offers a substantially stronger water-resistance certification with IP68 versus the Y400 Pro 5G's IP65.

Both phones share a strong display foundation — OLED/AMOLED panels of virtually identical size (6.78″ vs 6.77″) and nearly the same pixel density (~393 vs 388 ppi), meaning sharpness and color quality will be indistinguishable in everyday use. Where they diverge meaningfully is in refresh rate and content capability. The Tecno Camon 40 Pro 4G runs at 144Hz, delivering visibly smoother scrolling and more responsive gaming compared to the Y400 Pro 5G's 120Hz — a real, perceptible difference for users sensitive to motion fluidity, even if 120Hz is already well above average.

On the content side, the trade-off flips. The Vivo Y400 Pro 5G supports HDR10, which means streaming HDR content from compatible platforms will render with the intended wider dynamic range and tone-mapping. The Camon 40 Pro 4G lacks any HDR certification, so it misses out on this for video consumption. Meanwhile, the Camon counters with branded damage-resistant glass — a practical durability edge the Y400 Pro 5G does not offer, making the Camon's screen more resilient to everyday scratches and minor impacts.

On balance, the two displays are closely matched, but each holds a distinct advantage in different areas. The Camon 40 Pro 4G wins for gamers and general smoothness seekers with its higher refresh rate and tougher glass; the Y400 Pro 5G is the stronger pick for media consumption thanks to HDR10 support. Neither has a sweeping overall edge — the right choice depends on what the user values more: motion performance or richer streaming visuals.

At the heart of this comparison is a generational chipset gap. The Vivo Y400 Pro 5G runs on the MediaTek Dimensity 7300, built on a 4nm process, versus the Camon 40 Pro 4G's MediaTek Helio G100 on a 6nm node. A smaller semiconductor process means the Dimensity 7300 is architecturally more power-efficient and thermally cooler under sustained load — advantages that translate into better sustained performance and potentially longer battery life during intensive tasks. The Y400 Pro also fields faster CPU cores at 4 x 2.5 GHz compared to the Camon's top cluster of 2 x 2.2 GHz, giving it a raw single-core edge for demanding workloads.

The memory story is split but still favors the Y400 Pro on a technical level. The Camon 40 Pro 4G ships with 12GB of RAM versus the Y400 Pro's 8GB, which is a real advantage for heavy multitasking and keeping more apps resident in memory. However, the Y400 Pro's RAM operates at 6400 MHz DDR5 versus the Camon's 4266 MHz DDR4 — significantly faster bandwidth that helps the Dimensity 7300 feed its CPU and GPU more efficiently. On the graphics side, the Y400 Pro's Mali G615 MC2 is a newer GPU architecture than the Camon's Mali G57, and its support for DirectX 12 (vs DirectX 11) indicates broader compatibility with modern graphics workloads.

Taken together, the Vivo Y400 Pro 5G holds a clear performance advantage: its newer 4nm chip, faster CPU cores, superior GPU, DDR5 memory, and DirectX 12 support represent a meaningfully more capable and efficient platform. The Camon 40 Pro 4G's higher installed RAM cushions the gap for multitaskers, but it cannot offset the underlying architectural lead the Dimensity 7300 holds over the Helio G100.

Several practical advantages stack up in favor of the Tecno Camon 40 Pro 4G on the camera front. Its primary shooter pairs a 50MP main lens with an 8MP secondary lens, compared to the Y400 Pro 5G's 50MP main paired with a much more limited 2MP secondary — a sensor so low-resolution it typically serves only as a depth assist rather than a usable camera. More importantly, the Camon includes optical image stabilization (OIS), which physically compensates for hand movement during handheld shooting and is one of the most impactful real-world camera features available, directly improving sharpness in low light and smoothness in video. The Y400 Pro 5G lacks OIS entirely.

The video gap reinforces this advantage. The Camon records 4K at 60fps, delivering smoother, more cinematic footage compared to the Y400 Pro's 4K capped at 30fps. For anyone who shoots video regularly, this is a meaningful difference — 60fps captures fast motion far more cleanly and allows for smooth slow-motion playback in post. The Camon also features a dual-LED dual-tone flash versus a single LED on the Y400 Pro, which produces more balanced, natural-looking artificial lighting in dark environments. On selfies, the Camon's 50MP front camera holds a clear resolution advantage over the Y400 Pro's 32MP shooter, though the identical f/2.5 aperture means low-light selfie performance should be comparable.

Across nearly every differentiating camera spec, the Tecno Camon 40 Pro 4G comes out ahead — OIS, higher 4K frame rate, a more capable secondary lens, higher-resolution selfie camera, and a better flash system all point in the same direction. For users who prioritize photography and videography, the Camon holds a clear and well-rounded advantage over the Y400 Pro 5G.

This is a rare case of a complete dead heat. Both the Tecno Camon 40 Pro 4G and the Vivo Y400 Pro 5G run Android 15 and share an identical feature set across every single operating system specification provided — from privacy controls and multitasking capabilities to productivity tools and customization options. Split-screen support, Picture-in-Picture, dynamic theming, on-device machine learning, battery health checks, and offline voice recognition are all present on both devices without exception.

The privacy posture of both phones is equally matched: camera and microphone access controls, location privacy options, app tracking blockers, clipboard warnings, and notification permissions are all accounted for on each. Neither phone gets direct OS updates, and neither supports cross-site tracking blocking or Wi-Fi password sharing — shared limitations that apply equally to both.

With no differentiating data point anywhere in this group, the operating system category is a complete tie. Users can expect an functionally identical software experience from both devices based strictly on these specs, and this group should carry no weight in any purchase decision between the two.

Battery capacity is close but not identical: the Vivo Y400 Pro 5G packs a 5500 mAh cell versus the Camon 40 Pro 4G's 5200 mAh. The 300 mAh difference is modest and unlikely to translate into dramatically different screen-on time in daily use, but it does give the Y400 Pro a marginal endurance edge under equivalent workloads — particularly relevant given that its more efficient 4nm chipset (noted in the Performance group) will also draw less power, compounding the stamina advantage.

Where the gap becomes impossible to ignore is charging speed. The Y400 Pro 5G supports 90W fast charging — exactly double the Camon 40 Pro 4G's 45W. In practical terms, 90W charging can replenish a large battery from near-empty to a usable level in roughly 30 minutes or less, while 45W, though still respectable, will take noticeably longer. For users who rely on quick top-ups during short breaks, this difference is highly tangible. Neither phone supports wireless charging, so the wired charging speed is the only replenishment option for both.

The Vivo Y400 Pro 5G wins this category decisively. Its larger battery and significantly faster 90W charging combine to offer both more capacity and far quicker recovery — a compelling dual advantage for users who prioritize all-day endurance and minimal downtime at the charger.

For the most part, these two phones are evenly matched on audio. Both drop the 3.5mm headphone jack — meaning wired audio requires a USB-C adapter — and both feature stereo speakers, which deliver a noticeably wider, more immersive soundstage than mono setups for media consumption and calls. Neither device supports any high-resolution Bluetooth audio codec, including aptX, aptX HD, LDAC, or their variants, so wireless audio quality is limited to standard Bluetooth transmission on both.

The only differentiator in this group is the built-in FM radio on the Tecno Camon 40 Pro 4G, which the Vivo Y400 Pro 5G lacks entirely. While radio is a feature many users never touch, it holds genuine value in specific contexts — areas with limited data connectivity, emergency broadcasts, or markets where FM radio remains a primary media source. For users in those situations, its absence on the Y400 Pro is a real omission.

Overall, audio is nearly a tie, but the Camon 40 Pro 4G claims a narrow edge solely by virtue of its FM radio inclusion. For the vast majority of users focused on speaker or wireless headphone performance, both phones stand on equal footing in this category.

The single biggest divide in this category is cellular generation. The Vivo Y400 Pro 5G supports 5G; the Tecno Camon 40 Pro 4G does not, topping out at 4G LTE. This gap is reflected dramatically in the cellular speed figures: the Y400 Pro lists download and upload speeds of up to 3270 Mbits/s, compared to the Camon's 650 Mbits/s down and 150 Mbits/s up. In practical terms, wherever 5G coverage is available, the Y400 Pro can deliver significantly faster downloads, lower latency, and more reliable performance in congested areas — a future-proofing advantage that will only grow as 5G networks expand.

Wi-Fi capabilities are identical on both phones, both topping out at Wi-Fi 5 (802.11ac), so there is no advantage to either on local network performance. Both also share NFC, dual-SIM support, USB Type-C (USB 2.0), fingerprint scanning, GPS with Galileo support, gyroscope, and accelerometer — a solid and evenly matched baseline for daily connectivity and navigation needs. Neither phone offers an external memory slot, which is a shared limitation worth noting.

The Camon 40 Pro 4G does bring one exclusive to the table: a built-in infrared (IR) sensor, which allows the phone to function as a universal remote for TVs and other IR-controlled appliances — a genuinely useful convenience feature absent on the Y400 Pro. However, this does not come close to offsetting the Y400 Pro's 5G advantage. For users in or moving to 5G coverage areas, the Vivo Y400 Pro 5G holds a clear and consequential connectivity edge in this group.

The miscellaneous spec group offers no differentiation whatsoever between these two devices. Both the Tecno Camon 40 Pro 4G and the Vivo Y400 Pro 5G share a curved display design and include a video light, while neither features sapphire glass protection nor an e-paper display. Every data point in this group is identical across the two phones.

This is a complete tie with no basis for preferring one device over the other from these specs alone. This group carries no decision-making weight and should be set aside entirely when comparing the two phones.
