The verdict

Across 14 reviews from 11 outlets, the Vivo X300 Ultra is seen as a camera-first flagship with an excellent display and fast charging. Published scores run from 4/5 at Trusted Reviews to 4.75/5 at Android Central. Reviewers are far less united on sustained-load heat, bulk and price, so it suits buyers who put photography first and accept a heavy, expensive phone.

Best for: Photography-focused buyers who want a top-tier zoom and ultrawide camera and can accept a large, heavy phone.
Skip it if: You want a light, easy one-handed phone, steady thermals under heavy load, or a lower price.

In detail

Camera: 9.6/10

The camera is the clear reason to buy this phone. Trusted Reviews called it the most versatile photo and video phone available, and noted a 400mm external zoom lens that adds 4.7x magnification on top of the built-in telephoto. Android Central said it took the best photos of any phone it has tested, with its 10x telephoto beating the Galaxy S26 Ultra and Pixel 10 Pro XL. Smartprix Bytes rated the ultrawide the best of 2026. The caveats: DXOMARK found low-light noise, ghosting, AI artifacts and weaker video. Android Authority saw ultrawide distortion, and Beebom and 91mobiles noted soft selfies. NotebookCheck measured over-brightened colours.

Battery life: 8.8/10

Most outlets found the 6,600mAh battery comfortably lasts a full day. Android Authority measured seven to eight hours of screen-on time and suggested charging every other day with typical use. Trusted Reviews said lighter use often stretches into a second day, and Beebom ended days with 10-15% left. Digit recorded a PCMark runtime of about 24.6 hours. Heavy camera use shortens this, with 91mobiles rarely getting past one full day. NotebookCheck measured very high power use in its Wi-Fi test and placed it well behind the Oppo Find X9 Pro, while Smartprix Bytes found it slightly behind the Xiaomi and Oppo ultras.

Performance: 8.0/10

Raw speed is top-tier. Digit recorded the highest Antutu result it had seen on this chip, and Beebom found maximum-setting gaming smooth, helped by a large vapour chamber. FoneArena saw no frame drops in Call of Duty, BGMI or Genshin Impact. Sustained load is where reviewers split. FoneArena and Android Authority saw stress-test stability of roughly 54-64% with temperatures reaching about 50°C, and Android Authority found it much hotter than the Galaxy S26 Ultra. MySmartPrice Gear saw the CPU throttle, and NotebookCheck reported pronounced throttling and high idle power use. Evidence here is medium confidence because the thermal results conflict.

Display: 9.5/10

The 6.82-inch OLED earns broad praise. NotebookCheck measured near-4,500-nit HDR peak brightness, accurate colour, even brightness and a 1-144Hz refresh range with high-frequency PWM dimming. Trusted Reviews also measured about 4,500 nits and found daylight framing easy. Other outlets measured lower peaks: Digit about 2,830 nits, Beebom 3,300 nits in HDR and MySmartPrice Gear 2,240 nits, so figures depend on the test method. Android Central found it brighter than the X200 Ultra, with improved HDR and comfortable dimming. 9to5Google called it superb but a little short of the Galaxy S26 Ultra’s panel.

Software: 7.6/10

The phone runs OriginOS 6 on Android 16. NotebookCheck highlighted the promise of five years of updates and seven years of security patches, and noted a later firmware update improved power use under load. Beebom found it fast and clean but held back by preinstalled apps and App Store notifications that took about 10 minutes to remove. Android Central found data transfer from Android faster than Google’s tool, and noted notification issues on the Chinese version that can be fixed with memory settings. Digit called it usable, with features such as app lock and AI translation. 9to5Google was the most critical, finding the design and settings dated. Several outlets only listed the update promise, so evidence is medium.

Charging: 8.6/10

Outlets agree that 100W wired charging is quick, with 40W wireless as an extra. Android Central measured a full charge in just over 42 minutes, Digit and Beebom about 45, and Smartprix Bytes 46. Beebom saw 15% to 50% in 15 minutes. Trusted Reviews measured a slower full charge of 55 minutes with the included charger. 91mobiles measured 20% to full in 36 minutes but noted the phone warms up noticeably. Android Central added that 50W works with USB PD chargers. 9to5Google was less impressed, judging the jump over the Galaxy S26 Ultra’s 65W charging not significant.

Design & build: 8.0/10

Reviewers like the premium finish and IP68/IP69 water and dust resistance, but weight is the main complaint. Android Authority found the camera bump extremely thick and the phone much heavier than the Galaxy S26 Ultra. Trusted Reviews cited 239g and one of the largest bumps around. 91mobiles reported wrist strain in one-handed use. NotebookCheck and Beebom described it as top-heavy without a dedicated camera button. Android Central was more positive, praising the beveled two-tone frame and noting there is no table wobble. Digit liked the dense, expensive-feeling build, while MySmartPrice Gear found it bulky with accessories fitted.

Value: 6.3/10

Evidence on value is thin, since only some outlets discussed price, so treat this as an early read. Android Authority called the €1,999 European price extremely expensive, even against other Ultra flagships. NotebookCheck said the same price for the 16GB/1TB model sits above the Oppo Find X9 Ultra and Galaxy S26 Ultra. MySmartPrice Gear called it a costly investment. Smartprix Bytes was more forgiving, saying photographers get the best smartphone camera system of 2026. 9to5Google said it makes few compromises and competes with the best phones, but did not give a price verdict.

We read the reviews and articles listed above and weigh each by how much it should count: in-depth, hands-on testing with measurements counts most; launch news and press-release rewrites count least; sponsored content is penalised. Category scores are our trust-weighted summary of what those sources found, set to the same 10-point scale reviewers use; the reviewers’ own scores, where published, are listed above. This page was compiled with AI assistance and checked against the source notes. All findings belong to the outlets credited above; follow the links to read their full reviews. How we score.
