Vivo X300 Ultra review: Raising the bar for what a flagship should be in 2026
Follow Us
There are flagship smartphones, and then there is the Vivo X300 Ultra. And I don’t mean that in the usual reviewer way, where everything sounds like a big deal in the first paragraph. Trust me when I say this, the X300 Ultra is actually one of a kind. It’s one of those phones that initially grows on you, and then at some point you realise, okay, this is special. For me, it slots right alongside the Galaxy S26 Ultra (read review) and the iPhone 17 Pro Max. And up until now, if someone randomly asked me what flagship phone to buy, I have always instinctively said Samsung or Apple, because let’s be honest, they are safe, familiar choices. But this time, if anyone asks me the same question, I think I will take a pause. Because if you actually have the money to spend (over Rs 1.5 lakh in this case), I genuinely feel like saying, just go buy the X300 Ultra.
There are camera phones, and then there is the Vivo X300 Ultra. And it has kind of reset my expectations for a flagship phone in 2026. Here’s my full review.
We have to start with the camera; there’s no other way
The Vivo X300 Ultra doesn’t just have a good camera system; it’s a proper, fully loaded setup, which tells you that Vivo just went all in. I remember using the Vivo X200 Pro, and I thought that was peak smartphone photography. Nothing I tried after that, including the Xiaomi 14 Ultra, really matched the Vivo experience. And now the X300 Ultra just takes that idea and goes beyond. Also, it’s not just that it takes great photos. A lot of phones do that now. It’s how much control it gives you, and how consistently it delivers.
There are so many ways to shoot on this phone. You have your regular auto mode, which already does a solid job. But once you step into Pro mode, you start seeing what Vivo is trying to do here. You get full manual control, and yes, you can shoot in LOG as well.
And, did I tell you about the ridiculous zoom on this phone? And I don’t mean to say that in a spec-sheet bragging manner, but in the sense that it is actually usable. You simply go in, frame your shot, and still get detail that holds up. Plus, in doing so, the phone doesn’t even flinch, be it daylight or low-light.
But portraits… portraits are where I had the most fun.
You get multiple focal lengths: 14mm, 35mm, 85mm, 170mm, and even 230mm. And it’s not just there for show. You actually end up using them depending on the situation. I know I used a lot of 35mm for something natural, 85mm for that classic portrait look, and then the longer ones when I wanted something more dramatic.
The good part is that the output just hits. I am literally at a loss for words on how good the camera on this thing is. In photos, the skin tones look natural. There is no weird over-processing. The background separation is clean and not overly artificial. Basically, there’s a certain character to these images that is really hard to explain, but very easy to notice once you start using the phone. And boy, is it a joy using this camera!
In general photos, it’s the same story. You get excellent detail and dynamic range, but more importantly, you get consistency. You don’t have to second-guess whether the shot will come out well. I mean, you really have to be a bad photographer to capture a bad photo on the Vivo X300 Ultra.
There are also a lot of editing tools built in. Enough that you can actually finish your photos on the phone itself without jumping to Canva or even Photoshop.
And, if you are still not down with all this, there’s the whole ecosystem around the camera: the teleconverter kit (200mm and 400mm lenses) and the shooting rig. I, alongside my team, actually used this setup to shoot a short film called The Proof, which is up on the Digit YouTube channel. And we shot it entirely on the X300 Ultra. I’d really suggest checking out the film (linked at the bottom) for the video quality, and that alone should tell you enough about how versatile this thing is.
And speaking of video recording, I think Vivo has really stepped up this year. You see, photos were already sorted, but the video now feels properly flagship-level. Stabilisation is solid, colours are consistent, and it handles lighting really well. I would again bring up the example of our short film, because we shot it during the day and evening, indoors and outdoors, and the footage turned out very usable without much effort.
In fact, just last weekend, I even ended up comparing the X300 Ultra with our Sony A7III camera. And look, a proper camera is still a proper camera. But when I took those photos of Krishika, side by side, from both devices, there were moments where the Vivo held its own in a way that genuinely surprised me. In fact, I can’t believe I’m saying this, but I actually prefer the photos taken from the X300 Ultra over the Sony.
You can check out the full comparison by watching the video at this LINK.
If I had to rank camera phones right now, the Vivo X300 Ultra is easily number one for me. Then comes the Galaxy S26 Ultra, and then the iPhone 17 Pro Max. And that’s not me saying the others are bad. All three are incredible. But when it comes purely to the camera, this one just edges ahead.
Now, once you get past the camera, you may expect the rest of the phone to feel secondary. It doesn’t.
A design that feels as premium as it looks
The Vivo X300 Ultra has an interesting design. Yes, it is top-heavy, no doubt. That circular camera module is massive and sticks out quite a bit. But weirdly, that also makes the bottom half feel slimmer than it actually is. On paper, it’s about 8.2mm at its thinnest point, which is impressive considering everything inside.
In hand, the Vivo X300 Ultra feels… expensive. That’s the best way to put it. There’s this dense, solid feel to it, combined with a matte finish at the back that just feels nice. The sides are flat but slightly rounded, so they don’t dig into your fingers. I would still suggest using a case, because dropping this would hurt (emotionally and financially), but if you use it without one, like me, it feels amazing.
Durability is sorted too, with IP68 and IP69 ratings for dust and water resistance. You even get an IR blaster on top, which is a nice little bonus. USB-C 3.2 is here as well. The ultrasonic fingerprint is insanely fast, and paired with the superb haptic motor, the vibration feedback is quite satisfying every time I unlock the phone.
Honestly, at this point, I was trying to find something missing. The only thing that came to mind was Samsung’s privacy screen feature on the S26 Ultra. If this phone had that, it would have been dangerously close to perfect.
A display that keeps up with everything else
The Vivo X300 Ultra has an LTPO AMOLED screen, with a 6.82-inch size, 2K resolution, and a 144Hz refresh rate. And yes, it looks as good as it sounds. First up, there are a bunch of ways in which you can tailor the display experience on this phone. I have personally bumped up the resolution and refresh rate to max. For the colours, my favourite setting is Bright, because it just exhibits the complete range of vividness and punch.
So yes, everything looks vibrant on this thing, but not overdone. As vivid as the colours are, the blacks are equally deep, and everything just looks clean. It supports HDR10+ and Dolby Vision, so content looks great. For that matter, the audio output from the dual-stereo speakers sounds rich and full.
Vivo claims 1,800 nits HBM brightness, but in our testing at Digit Labs, it went up to 2,830 nits, which is kind of crazy. And you can feel it when you’re outdoors. Visibility is just not an issue.
In a nutshell, this is easily one of the best displays you can get on any flagship phone right now, period.
Power, software, and everything in between
Even when it comes to performance, there’s nothing to complain about. The Vivo X300 Ultra gets 16GB LPDDR5X Ultra RAM, 512GB UFS 4.1 storage, and the top-of-the-line Snapdragon 8 Elite Gen 5 under the hood. What this means is that this phone is fast. Quite literally, in the way the software has been optimised, and the way animations and transitions work, everything is snappy. App opening times are quick, app switching is smooth, RAM management is top-tier, and it just feels like a flagship phone in 2026 should.
The benchmark numbers back it up too. In Antutu, the Vivo X300 Ultra scored 3,807,530. This is actually the highest Antutu score I have recorded on any Snapdragon 8 Elite Gen 5 phone I have tested. Then, in Geekbench 6, the phone scored a solid 3,420 and 10,741 in single-core and multi-core performance, respectively. But honestly, you don’t even need to look at the benchmark scores, because as I said, the phone is fast.
By the way, gaming is solid as well. There’s support for 120fps in BGMI and COD: Mobile, while Genshin Impact is capped at 60fps. The gaming performance holds up, and thermals are managed nicely. However, yes, it did heat up when I used the camera rigorously, but that’s expected. The important part is that it doesn’t stop you from using it. Unlike iPhones, at least it doesn’t give up on you mid-shoot.
Finally, software is another area where Vivo quietly does a lot right. OriginOS 6 on Android 16 is actually very usable. I have already experienced it on the iQOO 15, iQOO 15R and now on the X300 Ultra. I think OriginOS is easily one of the best Android ROMS out there because you get features that people genuinely use. For instance, app locker, private space, app hiding, and app cloning are some of the practical additions I use. Customisation is also great. You can tweak things the way you like, including the lockscreen, the widgets, the way the clock looks, the display size, the AOD screen, fonts, icons, and so much more.
By the way, the AI features are there too, just in case you thought otherwise. The good part is that, thankfully, they are practical too. Photo editing tools, note summaries, recording and transcription in the recorder app, and my two personal favourites: native Screen Translation, which, as the name suggests, translates anything on the screen from one language to another. Especially useful when I am visiting a Chinese website, and I need a quick English translation. The second is getting AI captions in videos, and that too in your desired language. This comes in handy when a YouTube video doesn’t have captions, and it’s in a language I don’t understand (by the way, I only know English and Hindi), AI captions quickly translate it to English in real time.
I would again emphasise that these are OriginOS 6 features that I use in day-to-day life, and I feel the person who buys this phone will also use and appreciate them.
Battery life that keeps up with the rest
Battery life is yet another homerun for the Vivo X300 Ultra. And I know, you may think, is there anything wrong with the phone? Honestly, it is what it is.
The 6,600mAh silicon-carbon battery easily lasts a full day, and then some more, even with heavy use. In the PCMark battery test, it clocked 1,479 minutes, which is insane.
Charging is quick too: 100W wired and 40W wireless. Vivo includes a Type-C to Type-C PD charger in the box, which means that not only can it charge the X300 Ultra at 100W speeds, but even when I plugged in my Galaxy S26 Ultra or my MacBook Air M5, those devices are also able to take advantage of their maximum charging speeds.
By the way, the Vivo X300 Ultra takes about 45 minutes to fully top up from empty. But again, at no point did I feel like I needed to worry about the battery. And that kind of sums up the whole experience.
Vivo X300 Ultra: Should you buy it?
Will it be too far-fetched to say that the Vivo X300 Ultra is a near-perfect flagship? Because you need to understand, this phone is not just about having the best camera, even though it probably does. It’s about how complete the whole package feels.
Yes, the Galaxy S26 Ultra might still be the safer recommendation for most people. But if you are someone who actually cares about what your phone can do, especially with the camera, this one is very hard to ignore. In fact, it’s hard not to recommend it.
When you look at all the parameters, the Vivo X300 Ultra features a premium design, the display is excellent, performance is top-tier, the software is practical, and battery life is reliable. If you noticed, it nails every aspect of an all-rounder flagship smartphone.
In fact, for me, the X300 Ultra has set a new benchmark. I feel smartphone makers really need to pay attention here. And I’m genuinely curious about the upcoming Oppo Find X9 Ultra now, because that’s going to be an interesting fight.
But right now, as things stand, the Vivo X300 Ultra doesn’t just compete. It sets the bar.
