Vivo X300 Ultra Is The Most Complete Smartphone You Can Buy Right Now, And Its Camera System Changes Everything

First impressions matter, and the Vivo X300 Ultra does not arrive quietly. The large circular camera island on its rear panel dominates the design language in a way that is bold and intentional. The outer ring of this camera module features a ridged texture with smooth sections at the top and bottom for the Zeiss branding, giving it a refined, professional aesthetic that recalls high-end optical equipment rather than consumer electronics.

The Victory Green colour variant, which was used throughout this review, features a two-tone rear panel with a noticeably lighter shade in the lower section. The matte glass back feels premium in the hand and actively resists fingerprint smudges, which is a thoughtful choice for a phone this beautiful. The aluminium frame runs around the device with the volume rocker and side button placed on the right edge. The bottom edge houses the SIM tray, dual microphones, and the primary speaker grille, while the secondary speaker sits up top for a true stereo spread.

At 237 grams, the X300 Ultra is not the lightest device in Vivo's lineup, weighing 11 grams more than the X Fold5. However, the weight distributes evenly enough that extended use does not feel uncomfortable. One notable omission on the Ultra model is the Shortcut key found on the Pro variant, which some users accustomed to that convenience may find disappointing.

What the X300 Ultra does carry is an IP68 and IP69 dual rating, making it completely dustproof and waterproof with submersion capability up to 1.5 metres for 30 minutes. For a flagship phone carried in pockets and used across varied outdoor environments, this level of protection matters enormously.

The 6.83-inch LTPO AMOLED display rounds out the front-facing experience beautifully. With a 144Hz refresh rate, peak brightness of 4,500 nits, and a 2K resolution, this panel delivers visuals that are consistently impressive. Sunlight legibility is excellent, colours are vibrant without being overblown, and blacks carry that deep, natural quality that only OLED technology delivers at its finest. The slim bezels and smooth touch response make scrolling and navigation feel effortless. The under-display ultrasonic fingerprint sensor is noticeably faster and more reliable than optical alternatives on competing devices.

Under the hood, the X300 Ultra runs on Qualcomm's Snapdragon 8 Elite Gen 5, currently the most powerful mobile processor available for Android devices. The phone ships in a single configuration of 16GB LPDDR5X Ultra Pro RAM paired with 512GB of UFS 4.1 storage.

Benchmark results from testing confirm the performance pedigree. The device scored 3,877,653 on AnTuTu 3D, while Geekbench 6 returned a single-core score of 3,445 and a multi-core score of 9,274. These are top-tier numbers, but raw benchmarks only tell part of the story.

In daily use, the X300 Ultra handles every task with a smoothness that quickly becomes expected rather than impressive. Applications open instantly. Multitasking between a dozen apps simultaneously produces no lag. Video editing, whether short Reels or extended long-form content, runs without hesitation or thermal throttling. The UFS 4.1 storage contributes significantly to the snappy app loading experience, and the LPDDR5X Ultra Pro RAM ensures that background apps remain active and ready rather than forcing constant reloads.

Gaming performance deserves particular mention. BGMI and Call of Duty Mobile, two of the most demanding titles in the mobile gaming ecosystem, ran at maximum frame rates and highest graphics settings without any performance degradation. The 5,800 square millimetre vapour chamber cooling system proved effective throughout extended gaming sessions, with the back panel remaining impressively cool even after 30 minutes of intensive gameplay.

The X-axis linear motor is a detail that often goes unremarked in reviews but significantly shapes the feel of everyday use. The haptic feedback on the X300 Ultra is crisp, precise, and deeply satisfying in a way that elevates simple interactions like typing and receiving notifications.

The X300 Ultra ships with Android 16 layered with Vivo's OriginOS 6. The software experience is fluid, visually cohesive, and thoughtfully customised for the hardware it runs on. Sliding animations, app entry and exit effects, card transition styles, and dynamic effects for actions like fingerprint unlock, USB insertion, and screen activation are all adjustable to user preference, allowing meaningful personalisation.

Bloatware is present, and its inclusion on a flagship product remains an unfortunate industry habit. However, Vivo allows all pre-installed third-party apps to be fully uninstalled, which softens the frustration. The company has also committed to 5 major Android OS updates and 7 years of security patches, which is a serious long-term software support promise that few Android manufacturers match.

AI features are woven into the experience without being forced to the foreground. Writing tools for summarisation, proofreading, and text extension are accessible when needed. AI captions can be enabled in settings. The native voice recorder supports transcription and summarisation of voice memos. The photo editing suite within the Albums application includes AI-powered object eraser and detail enhancement tools. These are genuinely useful implementations rather than feature box-ticking exercises.

The camera system on the Vivo X300 Ultra is where this device truly distinguishes itself from the competition. Tuned in collaboration with Zeiss, the rear setup comprises a 200MP Sony LYTIA 901 primary sensor, a 200MP telephoto lens with 3.7x optical zoom, and a 50MP Sony LYT-818 ultrawide lens. A 50MP front-facing camera is housed in a punch-hole cutout at the top of the display.

The primary 200MP shooter operates at a 35mm focal length, which is slightly more zoomed in than the traditional 24mm perspective used by most flagship cameras. This focal choice benefits portrait and defined-subject photography enormously, delivering compositions that feel more deliberate and visually engaged. The image quality from this sensor is consistently exceptional. Detail resolution is remarkable, colours are rich and accurate without artificial boosting, and the 1/1.12-inch sensor gathers sufficient light in challenging low-light conditions to preserve essential detail. Night Mode enhances already capable low-light results further, producing well-illuminated images with natural colour reproduction.

Because the main camera defaults to 1.5x zoom, the 14mm ultrawide lens sees substantial daily use. This would present a problem on most smartphones, where ultrawide lenses typically produce softer, less detailed results than the primary sensor. The X300 Ultra is a different story. The 50MP ultrawide lens produces landscape images with sharpness and detail that genuinely rival, and in some scenes surpass, what competing flagship ultrawide lenses deliver. The tonal consistency between the main and ultrawide sensors is remarkably close, meaning photo sets taken across both cameras look coherent rather than like photographs from different phones. Night Mode on the ultrawide performs admirably, reducing noise and illuminating subjects with natural balance.

The 200MP telephoto lens at 3.7x optical zoom and 85mm focal length introduces a mild tonal shift toward cooler, slightly greyish tones compared to the main lens. This is a minor inconsistency in an otherwise excellent system. The telephoto resolves fine detail impressively at its native zoom level, and the AI-assisted zoom algorithm produces usable results up to 105x. For a zoom range that extends this far, maintaining structural detail and recognisable clarity is a genuine achievement.

Portrait photography is one of the X300 Ultra's most enjoyable applications. The 3.7x telephoto creates naturally shallow depth of field when photographing subjects from a distance, producing that sought-after DSLR-style separation between subject and background. Edge detection is precise, and background blur falls off in a way that looks optically natural rather than computationally manufactured.

The 50MP front-facing camera produces selfies with natural skin tones and minimal over-processing, which is refreshingly honest in a market where manufacturers frequently over-smooth facial textures. Video capabilities are extensive, with the front camera recording up to 4K at 60fps and all three rear cameras supporting 8K footage at 30fps.

The 6,600mAh battery powering the X300 Ultra is large enough to serve as a meaningful differentiator in real-world use. Heavy users, including those who spend significant time gaming, streaming video, and maintaining active social media use throughout the day, will reliably reach the end of the day with charge remaining. Users with moderate consumption patterns can comfortably push the battery to two full days between charges.

When the battery does need replenishing, the 100W fast charger included in the box brings the phone from zero to full in just under 50 minutes. This is a practical and competitive charging speed for a battery of this capacity.

The Vivo X300 Ultra at Rs 1,59,999 is not a compromise device. It is a statement of intent from a manufacturer that has built its reputation around camera quality and premium hardware. The Zeiss-tuned camera system here is genuinely among the best available on any smartphone at any price, with the ultrawide lens in particular standing apart from the competition in sharpness and colour accuracy.

The Snapdragon 8 Elite Gen 5 ensures that performance matches the camera ambition at every level. The 6.83-inch 2K AMOLED display is among the finest panels currently available on an Android phone. The battery lasts long and charges fast. The build quality communicates durability and premium craftsmanship in equal measure.

The omission of the Shortcut key available on the Pro model is a minor irritant, and the presence of bloatware, however removable, remains an unnecessary blemish on an otherwise impeccable package. The optional 200mm and 400mm telephoto extenders add cost for users who want the full photography ecosystem. These are genuine limitations worth acknowledging.

However, for photography enthusiasts, performance-focused users, and anyone seeking the most capable all-around Android flagship currently available in India, the Vivo X300 Ultra stands at the top of the category without serious challenge. This is a phone that genuinely delivers on its premium promise, and that is a rarer achievement than any specification sheet can convey.
