Realme 15x 5G (India) VS Vivo iQOO Z10R 5G

In terms of physical footprint, the Vivo iQOO Z10R 5G is the more compact and lightweight device across every measurable dimension. At 184 g versus 212 g, it is 28 grams lighter — a difference that is genuinely noticeable during extended one-handed use or all-day carrying. It is also slimmer at 7.4 mm compared to the Realme 15x's 8.3 mm, and its smaller overall volume (92.69 cm³ vs 107.40 cm³) means it will sit more comfortably in a pocket and feel less bulky in the hand.

On water resistance, the comparison is more nuanced. The Realme 15x 5G carries an IP69 rating, which certifies resistance to high-pressure, high-temperature water jets — a standard commonly associated with industrial durability. The iQOO Z10R holds an IP68 rating, which certifies sustained submersion in water at defined depths. In everyday life, both ratings offer strong protection against rain, splashes, and accidental spills, but the IP69 gives the Realme 15x a technical edge in harsher, more forceful water exposure scenarios.

Overall, the iQOO Z10R wins clearly on ergonomics and portability, while the Realme 15x counters with a higher-grade IP69 water resistance certification. Neither device has a rugged build or foldable form factor, so if compactness and lightweight handling are the priority, the iQOO Z10R has the edge; if maximum water resistance certification matters more, the Realme 15x has the advantage.

The single most important distinction here is panel technology. The iQOO Z10R uses an OLED/AMOLED panel, while the Realme 15x 5G relies on an LCD IPS display. In practice, OLED delivers true blacks, higher contrast, and more vibrant colors because each pixel produces its own light — making it significantly more suited to media consumption, dark-mode usage, and general visual quality. An LCD, regardless of how well-tuned, cannot match OLED in these areas at a fundamental hardware level.

Resolution is the other major gap. The iQOO Z10R renders at 1080 x 2392 px, while the Realme 15x 5G offers only 720 x 1570 px — a sub-HD resolution on a large 6.81-inch screen. Despite the Realme's marginally higher pixel density figure on paper (395 ppi vs 388 ppi), this is a quirk of its taller aspect ratio rather than a sign of superior sharpness; individual pixels on a 720p panel at this screen size are visible to the naked eye, particularly in text rendering and fine detail. The Realme does counter with a faster 144Hz refresh rate against the iQOO's 120Hz, which can make scrolling feel slightly smoother, but this advantage is modest and contextual.

The iQOO Z10R also supports an Always-On Display, a convenience feature the Realme 15x lacks entirely. Taken together, the iQOO Z10R holds a decisive advantage in this category — the OLED panel and full-HD resolution represent a categorically higher display tier, and no single spec on the Realme 15x is sufficient to offset that gap.

At the heart of this comparison is a clear chipset generational gap. The iQOO Z10R is powered by the MediaTek Dimensity 7400, built on a 4 nm process node, while the Realme 15x 5G runs the Dimensity 6300 on a 6 nm node. A smaller fabrication process generally means better power efficiency and thermal performance — the 7400 can sustain higher workloads while consuming less energy. The CPU configuration reinforces this: the Dimensity 7400 deploys four high-performance cores at 2.6 GHz compared to just two at 2.4 GHz on the 6300, giving the iQOO Z10R a more substantial performance cluster for demanding tasks like gaming or heavy multitasking.

The memory architecture gap is equally significant. The iQOO Z10R uses DDR5 RAM running at 6400 MHz with a maximum bandwidth of 25.6 GB/s, versus the Realme 15x's DDR4 at 2133 MHz and 17.07 GB/s. This nearly 50% bandwidth advantage means the iQOO Z10R can feed its CPU and GPU data far more rapidly, which translates to snappier app launches, smoother multitasking, and better sustained gaming performance. The iQOO Z10R also ships with 12 GB of RAM compared to 8 GB, providing more headroom for keeping apps in memory.

GPU performance follows the same pattern — the Mali G615 in the iQOO Z10R runs at 1047 MHz versus 950 MHz for the Realme 15x's Mali-G57. Storage capacity is equal at 256 GB for both. Across every meaningful performance dimension, the iQOO Z10R holds a clear and compounding advantage: newer silicon, faster and more abundant RAM, and a stronger GPU make it the considerably more capable performer of the two.

Two specs alone are enough to define the rear camera gap: optical image stabilization (OIS) and 4K video recording, both exclusive to the iQOO Z10R. OIS physically compensates for hand movement during shooting, resulting in noticeably sharper handheld photos in low light and steadier video footage — its absence on the Realme 15x means the phone relies solely on software stabilization, which is a meaningful real-world compromise. On video, the iQOO Z10R captures at 2160p (4K) at 30 fps while the Realme 15x tops out at 1080p at 30 fps, a full resolution tier lower. For anyone who values video quality, this difference is substantial and non-negotiable.

The iQOO Z10R also fields a dual rear camera system (50 MP + 2 MP), giving it a secondary lens the Realme 15x entirely lacks. The Realme 15x counters on the selfie side, however, with a 50 MP front camera against the iQOO Z10R's 32 MP — a meaningful edge for users who prioritize self-portraits or video calls. The Realme 15x also includes a dual-tone LED flash with two LEDs, which can produce more natural-looking flash photography compared to the iQOO Z10R's single LED.

Beyond these differentiators, the two phones share an identical feature set: phase-detection autofocus, continuous autofocus during recording, HDR mode, slow-motion, timelapse, and a full suite of manual controls. The shared foundation is solid, but the iQOO Z10R's OIS and 4K capability give it a decisive edge for rear camera versatility — while the Realme 15x earns a narrow win specifically on selfie resolution.

This is a rare case of a complete dead heat. Both the Realme 15x 5G (India) and the iQOO Z10R 5G run Android 15 and share an identical feature set across every single tracked specification in this group — from privacy controls and dark mode to split-screen multitasking, Picture-in-Picture, dynamic theming, and offline voice recognition. There is not a single differentiating data point between them here.

The shared Android 15 foundation means both phones benefit from the same generation of privacy tooling — including camera and microphone access indicators, app tracking controls, and granular notification permissions — as well as productivity features like full-page screenshots, widget support, and multi-user capability. Notably, neither device receives direct OS updates straight from Google, meaning software updates will be filtered through each manufacturer's own release schedule, a limitation that applies equally to both.

With no differentiators present in the provided data, this category is a definitive tie. A buyer choosing between these two phones on software alone has no basis for preference — the decision will hinge entirely on the other specification groups.

Battery capacity is where the Realme 15x 5G strikes back decisively. Its 7000 mAh cell is a genuinely large battery by any standard, sitting 1300 mAh above the iQOO Z10R's 5700 mAh — a 23% difference that translates directly into longer time between charges. For heavy users, frequent travelers, or anyone in situations where charging access is limited, that margin is meaningful and hard to dismiss.

The Realme 15x also charges faster, at 60W versus the iQOO Z10R's 44W. Despite having a larger battery to fill, the higher wattage means it can recover charge more quickly when plugged in. The iQOO Z10R's 44W is still respectable fast charging, but it is outpaced on both capacity and replenishment speed here. Neither phone supports wireless charging, so that shared limitation does not factor into the comparison.

For this category, the Realme 15x 5G has a clear and unambiguous advantage. A bigger battery combined with faster wired charging makes it the stronger choice for endurance-focused users — and represents one of the most compelling reasons to consider it over the iQOO Z10R.

Audio is a lean category for both devices, but the one differentiator that exists is meaningful. The iQOO Z10R features stereo speakers, while the Realme 15x 5G does not. In practical terms, stereo speakers produce sound from two directions simultaneously, creating a wider, more immersive soundstage for media playback, gaming, and speakerphone use. A single mono speaker, by contrast, projects audio in one direction only — a noticeably inferior experience when watching video or listening to music without headphones.

Everything else in this category is identical — and notably sparse. Neither phone includes a 3.5 mm headphone jack, meaning wired audio requires an adapter or USB-C headphones on both devices. Neither supports any high-resolution Bluetooth audio codec such as aptX, aptX HD, LDAC, or aptX Adaptive, which limits wireless audio quality to standard Bluetooth transmission for both. There is no FM radio on either device.

Given the limited feature set shared across both phones, the iQOO Z10R's stereo speakers stand as the sole differentiator and are enough to give it a clear edge in this category — particularly for users who frequently consume media through the built-in speakers.

Wireless connectivity is where the iQOO Z10R pulls ahead in a few targeted but practical ways. Most notably, it supports Wi-Fi 6 (802.11ax) in addition to Wi-Fi 4 and 5, while the Realme 15x 5G tops out at Wi-Fi 5. Wi-Fi 6 delivers better throughput, lower latency, and significantly improved performance in congested network environments — such as offices, apartments, or public spaces with many connected devices. The iQOO Z10R also edges ahead on Bluetooth 5.4 versus 5.3 on the Realme 15x, a minor generational step that brings marginal improvements in connection stability and efficiency. It additionally includes a gyroscope, a sensor the Realme 15x lacks entirely — relevant for gaming, augmented reality applications, and accurate screen rotation based on orientation.

The Realme 15x counters with one meaningful advantage: an external memory slot, which the iQOO Z10R does not offer. For users who want to expand storage affordably or transfer files easily via a microSD card, this is a practical and tangible benefit that the iQOO Z10R simply cannot provide. Both phones share the same USB 2.0 Type-C connection, dual SIM support, 5G, GPS, compass, accelerometer, and fingerprint scanner — and notably, neither includes NFC, which rules out contactless payments for both.

On balance, the iQOO Z10R holds the broader connectivity edge with its superior Wi-Fi standard and added gyroscope, while the Realme 15x offers the more user-friendly storage flexibility. Buyers who prioritize network performance and sensor capability will lean toward the iQOO Z10R; those who value expandable storage will find the Realme 15x more accommodating.

The Miscellaneous category offers no differentiating information between these two devices. Both the Realme 15x 5G (India) and the iQOO Z10R 5G share identical attributes across every tracked spec here: 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 by the data provided, and neither phone holds any advantage in this group. Buyers should weigh the other specification categories — particularly display, performance, battery, and connectivity — when making their final decision.
