Realme 15x 5G (India) VS Vivo iQOO Z10R 5G (128GB / 8GB RAM)

The most immediately noticeable difference in this group is physical size and weight. The Realme 15x 5G is heavier at 212 g and thicker at 8.3 mm, while the iQOO Z10R 5G comes in at a significantly lighter 184 g and a slimmer 7.4 mm. That 28 g gap is genuinely perceptible during extended one-handed use — it reduces fatigue during long sessions and makes the device feel more premium in the hand. The Z10R is also more compact across all three dimensions, giving it a noticeably smaller overall volume (92.7 cm³ vs 107.4 cm³), which translates to better pocketability and easier reach across the screen.

On water protection, the picture is more nuanced. The Realme 15x carries an IP69 rating, which certifies resistance to high-pressure, high-temperature water jets — a scenario relevant to heavy rain or rinsing under a tap. The iQOO Z10R holds an IP68 rating, which certifies sustained submersion in water. Neither has a rugged build, and neither is foldable. Despite the Realme being labeled merely ″Water resistant″ versus the Z10R's ″Waterproof″ branding, the IP69 certification is objectively a more demanding standard in terms of pressure tolerance, so the real-world protection offered by both is strong — just suited to different threat scenarios.

Overall, the iQOO Z10R 5G holds a clear ergonomic edge in this group: it is meaningfully lighter, thinner, and more compact, with no trade-off in build protection. For users who prioritize comfort during daily handling, the Z10R is the stronger choice here.

Panel technology is where these two devices diverge most sharply. The iQOO Z10R uses an OLED/AMOLED display, which delivers true blacks, higher contrast ratios, and more vibrant colors compared to the Realme 15x's LCD IPS panel. In everyday use, this means richer visuals when watching video, better legibility in sunlight due to improved contrast, and — a practical bonus — pixel-level dimming that enables an Always-On Display, a feature the Realme entirely lacks.

Resolution is another meaningful gap. The Z10R renders at 1080 x 2392 px, a full HD+ standard, while the Realme 15x outputs only 720 x 1570 px — HD+ territory. Despite the two phones having nearly identical pixel densities on paper (395 ppi vs 388 ppi), those numbers are misleading here: the Realme achieves its density on a slightly larger screen by pushing fewer total pixels, meaning text sharpness and fine detail in images will be noticeably softer. The one spec where the Realme pushes back is refresh rate — 144Hz versus the Z10R's 120Hz — which can make scrolling and animations feel marginally smoother. However, this advantage is subtle and largely offset by the Z10R's superior panel quality.

Taken together, the iQOO Z10R 5G holds a decisive display advantage. A full-HD+ AMOLED screen with Always-On support outweighs the Realme's higher refresh rate for the vast majority of use cases, particularly media consumption and general day-to-day visibility.

At the heart of this comparison is a clear generational gap in silicon. The iQOO Z10R is built on the Dimensity 7400 fabricated at 4 nm, versus the Realme 15x's Dimensity 6300 on a 6 nm process. A smaller node means the Z10R's chip is more power-efficient and capable of higher sustained performance without thermal throttling — a real-world benefit during gaming sessions or prolonged multitasking. The CPU configuration reinforces this: the Z10R fields four high-performance cores at 2.6 GHz compared to just two at 2.4 GHz on the Realme, giving it a stronger hand in demanding workloads. The GPU clock advantage (1047 MHz vs 950 MHz) points in the same direction for graphics-intensive tasks.

Memory architecture tells an equally stark story. The Z10R uses DDR5 RAM at 6400 MHz against the Realme's DDR4 at 2133 MHz — a roughly 3x difference in memory speed — resulting in a maximum memory bandwidth of 25.6 GB/s versus 17.07 GB/s. Faster memory directly reduces latency when loading apps, switching between tasks, and processing large data sets. The Z10R also supports up to 16 GB of RAM versus 12 GB on the Realme, providing more headroom for virtual RAM expansion.

The Realme 15x does have one concrete advantage here: 256 GB of internal storage versus the Z10R's 128 GB, which matters for users who store large amounts of media locally without relying on cloud services. But in raw processing capability, memory speed, and chip efficiency, the iQOO Z10R 5G holds a clear and multi-layered performance edge in this group.

Both phones share a 50 MP primary sensor, but the surrounding hardware tells a different story. The iQOO Z10R pairs its main lens with a secondary 2 MP shooter, making it a dual-lens system — the Realme 15x is single-lens only. More impactful, however, is the Z10R's inclusion of optical image stabilization (OIS), which the Realme lacks entirely. OIS physically compensates for hand movement during capture, producing sharper images in low light and significantly smoother handheld video — a meaningful real-world advantage that no software processing can fully replicate.

Video capability is another area where the gap is hard to ignore. The Z10R records at 4K (2160p) at 30 fps, while the Realme 15x tops out at 1080p at 30 fps. For users who shoot video — even casually — this is a two-generation jump in resolution ceiling. On the selfie side, the Realme counters with a 50 MP front camera versus the Z10R's 32 MP, which gives the Realme an edge for portrait selfies and front-facing detail — though aperture values are nearly identical between the two (2.4f vs 2.45f), so light intake is comparable.

Weighing it all, the iQOO Z10R 5G holds the stronger overall camera package. OIS and 4K video recording are tangible, everyday advantages that outweigh the Realme's higher-resolution front sensor for most users. The Realme 15x's selfie edge is real but narrow, making the Z10R the more versatile imaging device based on these specs.

This is a rare case of complete parity. Both the Realme 15x 5G and the iQOO Z10R 5G run Android 15 and share an identical feature set across every single specification in this group — from privacy controls like location and camera/microphone permissions to usability features such as split-screen multitasking, Picture-in-Picture, dynamic theming, and on-device machine learning. Neither receives direct OS updates, and neither supports Wi-Fi password sharing or focus modes.

For users weighing software experience as a factor, the provided data offers no basis to favor one device over the other. The practical day-to-day Android experience — customization depth, privacy tooling, productivity features — is effectively identical on paper. Any real differences would stem from each brand's proprietary UI skin layered on top of Android, which falls outside the scope of the data provided here.

This group is a complete tie. Neither the Realme 15x 5G nor the iQOO Z10R 5G holds any software advantage over the other based on the available specifications.

Battery capacity is where the Realme 15x 5G makes its strongest statement in this entire comparison. Its 7000 mAh cell is a substantial 1300 mAh larger than the iQOO Z10R's 5700 mAh — a difference of roughly 23%. In practical terms, that gap translates to meaningfully more screen-on time between charges, making the Realme a compelling option for heavy users, frequent travelers, or anyone who regularly ends the day with an empty battery.

On charging speed, the dynamic partially reverses. The Realme tops out at 60W versus the Z10R's 44W, so the Realme actually refills its larger battery faster in absolute wattage terms — a double advantage in this category. Neither phone supports wireless charging, and both feature non-removable, rechargeable batteries with a battery level indicator, leaving no further differentiators to consider.

The Realme 15x 5G wins this group clearly and decisively. A significantly larger battery combined with faster wired charging means more time away from the outlet and less time waiting when you do plug in — two of the most user-facing battery metrics that matter in daily use.

Audio hardware is sparse on both devices, but there is one spec that separates them. The iQOO Z10R 5G features stereo speakers, while the Realme 15x 5G does not. For media consumption — streaming video, gaming, or listening without headphones — stereo output creates a noticeably wider soundstage and more immersive audio compared to a single mono speaker. It is one of those features that is easy to overlook on a spec sheet but immediately apparent during everyday use.

Everything else in this group is identical. Neither phone includes a 3.5 mm headphone jack, so wired audio requires an adapter or USB-C headphones on both devices. Neither supports any high-resolution Bluetooth codec — no aptX, aptX HD, LDAC, or their variants — meaning wireless audio quality is capped at standard Bluetooth levels on both. There is no FM radio on either device.

Given the limited scope of differentiators here, the iQOO Z10R 5G takes a narrow but clear edge in this group solely on the strength of its stereo speaker setup — the one feature with a tangible impact on the day-to-day audio experience.

Wireless connectivity is where the iQOO Z10R pulls ahead in this group. It supports Wi-Fi 6 (802.11ax) in addition to the Wi-Fi 4 and 5 standards that both phones share, while the Realme 15x tops out at Wi-Fi 5. Wi-Fi 6 delivers higher throughput, lower latency, and better performance in congested environments — a meaningful upgrade for users on modern routers in busy households or offices. The Z10R also edges ahead on Bluetooth 5.4 versus the Realme's 5.3, a minor but forward-leaning improvement in connection stability and efficiency. Additionally, the Z10R includes a gyroscope while the Realme 15x does not — a sensor that enables more accurate motion-based gaming controls, AR applications, and image stabilization assistance.

The Realme 15x counters with one practical hardware advantage: it has an external memory card slot, whereas the Z10R does not. For users who need to expand beyond the built-in storage or easily transfer large files between devices, this is a tangible convenience the Z10R simply cannot offer. Both phones share the same USB Type-C 2.0 port, dual SIM support, fingerprint scanner, GPS with Galileo, and accelerometer, with neither including NFC — a notable omission for contactless payments on both devices.

Balancing the tradeoffs, the iQOO Z10R 5G holds a modest overall edge in this group through its superior Wi-Fi standard and gyroscope inclusion, though users who prioritize storage flexibility will find the Realme 15x's expandable memory a compelling counterpoint.

This group presents no differentiation whatsoever between the two devices. Both the Realme 15x 5G and the iQOO Z10R 5G share identical values across every available specification: both include a video light, and neither features a sapphire glass display, a curved display, or an e-paper display.

This is a complete tie. The provided data offers no basis to favor either device, and no spec in this group carries any decision-making weight for prospective buyers choosing between the two.
