vivo X300 Ultra

vivo X300 Ultra Price in Kenya, Full Specifications and Review (2026)

The vivo X300 Ultra price in Kenya is KSh 209,000, and independent testing backs up its position at the very top of vivo’s lineup with numbers that are genuinely hard to argue with: an AnTuTu v11 score exceeding 4 million, a GeekBench 6 multi-core result of 11,494, and a measured display brightness of 1,935 nits. This is vivo’s no-compromise flagship, built around the Qualcomm Snapdragon 8 Elite Gen 5 on a 3nm process, a triple 200MP Zeiss camera system with a genuinely rare dual-200MP main-and-telephoto arrangement, gimbal-stabilized OIS on the main lens, and a modular ecosystem of optional add-on zoom lenses that turn the phone into something closer to a compact camera system than a conventional smartphone.

The gimbal OIS on the main camera deserves specific attention, because it’s a meaningfully different stabilization technology from the sensor-shift OIS found on most rival flagships, including vivo’s own X300 E and X300 Pro. Sensor-shift OIS moves the camera sensor itself in a small, limited range to counteract hand shake. Gimbal OIS, by contrast, suspends the entire camera module on a mechanical gimbal that can tilt and shift across a considerably wider range of motion, similar in principle to the gimbal stabilization used in dedicated camera rigs. In practical terms, this means the X300 Ultra’s main camera can correct for significantly more aggressive hand shake and movement than sensor-shift OIS allows, a genuinely tangible difference in handheld low-light photography and video, particularly while walking or in situations with more pronounced camera movement.

The optional add-on zoom lenses are a genuinely unusual feature worth explaining in full, since nothing else in this price bracket offers anything comparable. Rather than being limited to the built-in 3.7x periscope telephoto, buyers can attach a separate 200mm lens (2.35x additional optical zoom) or a 400mm lens (4.7x additional optical zoom), both featuring their own OIS and Zeiss optics, physically extending the phone’s optical reach well beyond what’s built into the chassis. This effectively turns the X300 Ultra into a modular camera system, where the built-in triple-lens array covers everyday shooting and the add-on lenses handle specialized long-range photography, wildlife, sports, distant architecture, that would otherwise require a dedicated camera with a physical zoom lens.

At KSh 209,000, the vivo X300 Ultra sits considerably above the vivo X300 at KSh 49,000, confirmed in stock at Phonesstore Kenya, with the Ultra’s genuinely flagship-tier Snapdragon 8 Elite Gen 5, dual-200MP camera system with gimbal OIS, and modular add-on lens ecosystem as its extensive advances over the base X300’s more accessible Dimensity 9500 chipset and single 200MP Zeiss camera at a fraction of the price.

You can buy the vivo X300 Ultra from Phonesstore Kenya, where it is available with competitive pricing and nationwide delivery across Kenya.

Design and Build Quality

At 232 or 237 grams, depending on which SIM configuration is chosen, the X300 Ultra carries genuine flagship heft, a direct consequence of housing dual 200MP sensors, a gimbal-mounted stabilization mechanism, and a 6600mAh battery in one chassis. Armor glass on the front, rated at Mohs level 4, is a real but modest scratch-resistance figure worth naming honestly, Mohs level 4 sits below the level 5 and 6 protection some rivals achieve, meaning this glass will resist softer materials but remains more vulnerable to genuinely hard, sharp contact than the toughest competing display glass on the market.

The IP68/IP69 rating provides comprehensive water resistance, covering both sustained immersion to 1.5 metres for 30 minutes and, per the IP69 component, resistance to high-pressure, high-temperature water jets, a meaningfully more robust standard than basic splash protection. It’s worth noting the independently measured Class B EU free-fall rating, covering 180 drops, sits a tier below the Class A ratings the very toughest rivals achieve, a real, honest trade-off to weigh against everything this phone gets right elsewhere.

Display Quality

This display is genuinely exceptional, and the independently measured figures back that up decisively. A 6.82-inch LTPO AMOLED panel at 1440 x 3168 pixels, working out to a sharp 510 ppi, delivers QHD+-level detail considerably sharper than the Full HD+ panels still common even among flagship rivals. The independently measured 1,935 nits of maximum brightness is a genuinely outstanding real-world result, not a marketing claim but a figure verified through actual testing, placing this display among the brightest available on any smartphone currently on the market.

The 144Hz refresh rate provides an extra edge of smoothness over the 120Hz standard most rivals settle for, and the 2160Hz PWM dimming frequency is worth explaining specifically: PWM dimming controls brightness at lower levels by rapidly flickering the display, and at low frequencies that flicker can be genuinely perceptible, contributing to eye strain for sensitive users during extended nighttime use. At 2160Hz, that flicker cycle happens roughly nine times faster than the 240Hz baseline common on budget AMOLED panels, pushing it well past the threshold of human visual perception even under close scrutiny.

Performance and Chipset

The Qualcomm Snapdragon 8 Elite Gen 5 on a 3nm process, built around Qualcomm’s custom Oryon V3 architecture with a 4.6GHz prime core, delivers genuinely top-tier performance, and the independently measured benchmarks confirm it decisively rather than repeating manufacturer claims. An AnTuTu v11 score exceeding 4 million and a GeekBench 6 multi-core result of 11,494 place the X300 Ultra comfortably among the fastest smartphones tested anywhere in 2026, and the Adreno 840 GPU backed that up with a 3DMark Wild Life Extreme score of 7,075, confirming genuinely strong sustained graphics performance for the most demanding mobile games without meaningful throttling concerns.

12GB or 16GB of RAM paired with UFS 4.1 storage, available up to a full 1TB, gives the X300 Ultra genuinely no-compromise memory and storage specifications matched to its flagship-tier performance ambitions.

Camera Performance

This is genuinely one of the most comprehensive camera systems available on any phone, and it earns that distinction through specific, meaningful engineering choices rather than raw megapixel counts alone. The 200MP main sensor, at a large 1/1.12-inch size, paired with gimbal OIS, is the standout: gimbal stabilization allows for a considerably wider range of physical correction than the sensor-shift OIS used on most rivals, meaning handheld low-light photos and video hold up noticeably better under real-world hand movement than competing flagship cameras typically manage.

The 200MP periscope telephoto, at 3.7x optical zoom with its own dedicated OIS and multi-directional PDAF, is a genuinely rare specification, since pairing a full 200MP sensor with telephoto optics, rather than reserving the highest resolution for the main lens alone, gives zoomed shots meaningfully more retained detail than the lower-resolution telephoto sensors most rivals use. The 50MP ultrawide, itself carrying OIS, a feature frequently omitted from ultrawide lenses even on flagship phones, rounds out a genuinely versatile built-in three-lens system.

The optional 200mm and 400mm add-on Zeiss lenses extend this system into genuinely specialized territory, giving photographers optical reach that would otherwise require a dedicated telephoto camera lens, useful for wildlife, distant sports action, or architectural photography where even the built-in 3.7x periscope isn’t sufficient. Video capability tops out at 8K at 30fps, with 4K available at up to 120fps and support for 10-bit Log recording and 3D LUT import, features aimed squarely at serious videographers who want professional color grading control.

Battery Life and Charging

The independently measured 15-hour 45-minute active use score, combined with an EU Energy Label endurance rating of 56 hours 53 minutes, confirms the 6600mAh silicon-carbon battery delivers genuinely strong real-world performance, though it’s worth noting these figures sit somewhat behind the most extreme battery-focused flagships on the market, a reasonable trade-off given how much of the phone’s engineering budget clearly went into the camera system and gimbal stabilization mechanism instead.

100W wired charging, supporting the open PD, PPS, QC, and UFCS standards, gives genuinely broad compatibility with third-party chargers rather than locking buyers into a single proprietary system, and 40W wireless charging is a genuinely fast speed that few rivals match even in the flagship tier. Both reverse wired and reverse wireless charging round out a comprehensive charging ecosystem.

Who Is the vivo X300 Ultra For?

Ideal for:

• Serious photography enthusiasts who want a genuine dual-200MP camera system with gimbal-stabilized main lens and optional add-on telephoto lenses
• Buyers who want independently verified, class-leading benchmark performance and display brightness
• Videographers who need 8K recording, 10-bit Log, and 3D LUT import for professional color grading workflows
• Anyone who wants the widest available optical zoom range on a smartphone, extendable via modular add-on lenses

Not ideal for:

• Buyers on any kind of budget, given the significant price gap to vivo’s own base X300 model
• Anyone who wants the highest available drop-resistance rating, where the Class B rating trails some rivals
• Users who don’t shoot photography seriously and would be paying a substantial premium for camera capabilities they won’t use

Pros and Cons

The vivo X300 Ultra has genuinely exceptional, independently verified strengths at KSh 209,000. It delivers the Snapdragon 8 Elite Gen 5 with benchmark results among the best tested anywhere, a 6.82-inch 510 ppi LTPO AMOLED display with an independently measured 1,935 nits of brightness, a dual-200MP triple camera system with gimbal OIS on the main lens, genuine 3.7x optical telephoto zoom extendable via optional 200mm and 400mm Zeiss add-on lenses, 8K video with 10-bit Log support, IP68/IP69 water resistance, a 6600mAh battery with 100W wired and 40W wireless charging on open charging standards, and Wi-Fi 7, at KSh 209,000.

Its main limitations are the Mohs level 4 display glass protection that trails tougher options some rivals offer, a Class B EU free-fall rating rather than Class A, no expandable storage, and a battery endurance figure that, while strong, sits behind the most extreme battery-focused flagships given how much engineering priority went into the camera system instead.
