Sonyβs new Xperia 1 VIII is drawing some criticism online, though this time it is not about the cameras or pricing. Instead, the discussion is centered around the phoneβs actual thickness versus what Sony officially lists on the spec sheet.
Sony advertises the Xperia 1 VIII at 8.3mm thick, but well-known leaker @OnLeaks recently measured the device and arrived at roughly 8.59mm instead. That may sound like a tiny difference, but it was enough to spark debate about how smartphone brands report dimensions in the first place.
The front and rear glass panels of the Xperia 1 VIII sit slightly above the metal frame, which Sony could be excluding from its thickness measurements. In other words, Sony appears to be measuring just the middle frame thickness.
The internet already mocked Apple for advertising the iPhone 17 Air at 5.64mm despite its huge camera bar reaching roughly 11.32mm in thickness. Now Sony seems to be taking things a step further by excluding part of the phone body users actually hold.
Sony might have some justification for this new way of measuring thickness, just as it did during the recent AI Camera Assistant controversy. Unfortunately, there has been no official response so far, so we cannot say for sure how the company measured the Xperia 1 VIII and arrived at the 8.3mm figure.
Most people probably would never notice a 0.29mm difference in daily use. Still, the situation touches on a larger issue that has existed in the smartphone industry for years. Brands often advertise the thinnest possible point of a device while ignoring protruding camera bumps or slightly raised glass edges.
Some companies even end up with small dimension differences between color variants because of coating layers or material changes, yet the marketing almost always highlights the smallest number possible.
At the end of the day, this is not exactly a scandal-level controversy. But it does highlight how smartphone measurements can sometimes be more complicated than the clean numbers listed on product pages. For buyers who care about ergonomics and in-hand feel, independent measurements and hands-on reviews still matter quite a bit.
Vivo X300 Ultra and Sony Xperia 1 VIII represent two completely different visions of what an ultra-premium Android flagship should be in 2026. Vivo is chasing maximum hardware dominance with a massive battery, extreme camera setup, and ultra-fast charging, while Sony continues to refine its creator-focused Xperia formula with professional camera tools, expandable storage, and one of the few remaining headphone jacks in a flagship phone.Β
Both devices sit at the very top of the Android market, but they target very different kinds of users. This comparison breaks down which flagship actually delivers the better overall experience in design, performance, cameras, battery life, and long-term value.Β
Please note: Since the Sony Xperia 1 VIII is still expected to launch in June 2026, some specifications, features, and pricing could change before the official release.Β

Design and Display
Build and Feel
The Vivo X300 Ultra and Sony Xperia 1 VIII approach flagship design very differently. Vivo focuses on a bold ultra-premium camera-centric style with curved edges, a polished aluminum frame, and strong IP68/IP69 protection. The phone feels futuristic and luxurious, especially with the massive camera module that clearly signals its imaging ambitions. Sony, meanwhile, keeps its signature minimalist Xperia identity with flatter sides, Gorilla Glass protection, and a cleaner professional look. The Xperia feels more practical for long-term use thanks to the dedicated microSD slot and headphone jack, which are becoming increasingly rare in flagship phones.
Display Quality
Vivo easily pushes ahead in raw display specifications. Its LTPO AMOLED panel offers a sharper 1440p resolution, smoother 144Hz refresh rate, Dolby Vision support, and extremely high brightness handling. Content consumption and gaming feel more immersive and premium. Sonyβs OLED panel is still color-accurate and cinematic with HDR BT.2020 tuning, but the lower resolution and 120Hz refresh rate feel conservative for a 2026 ultra-flagship. Sonyβs display is clearly tuned for creators, while Vivo aims for maximum visual impact.
Verdict
The Xperia 1 VIII feels cleaner and more functional, but the Vivo X300 Ultra delivers the more modern and visually impressive flagship experience overall.
Specifications Including Battery
Performance
Both phones run on Qualcommβs Snapdragon 8 Elite Gen 5 chipset paired with the Adreno 840 GPU, so flagship-grade performance is guaranteed on either side. Heavy gaming, AI processing, multitasking, and 4K video editing should run effortlessly. Vivo, however, appears more aggressive with overall optimization. The combination of UFS 4.1 storage, a high-refresh display, and OriginOS tuning makes the phone feel exceptionally fast in daily use. Sony takes a more balanced approach focused on sustained performance and creator-oriented stability. Features like bypass charging and native Sony Alpha support make it especially appealing for photographers and videographers.
Battery and Charging
Battery capacity is one of Vivoβs biggest strengths. The massive 6600mAh battery paired with 100W wired and 40W wireless charging significantly outclasses Sonyβs 5000mAh setup with 30W charging. Vivo clearly targets power users who demand long endurance and minimal downtime. Sonyβs battery system is more conservative but likely healthier for long-term battery lifespan. Still, charging speeds now matter heavily in premium phones, and Vivo simply feels more future-ready here.
Verdict
Sony offers refined stability and creator-focused features, but Vivo dominates in battery life, charging technology, and overall flagship performance feel.
Camera
Main and Secondary Lenses
Camera hardware is where the Vivo X300 Ultra becomes extremely difficult to ignore. Its dual 200MP setup with large sensors, gimbal stabilization, Zeiss optics, and optional external zoom lenses creates a camera system that feels closer to dedicated photography equipment than a smartphone. Low-light shots, zoom quality, and cinematic video recording are likely among the best in the market. Sony takes a different route by focusing on natural color science, eye tracking, Alpha-inspired controls, and balanced lens consistency. The Xperia 1 VIII may produce more realistic photos, especially for creators who prefer manual tuning over aggressive computational photography.
Selfie Camera
Vivo again carries stronger hardware with a 50MP autofocus selfie camera capable of detailed 4K recording. Sonyβs 12MP front camera prioritizes natural tones and stable video rather than extreme detail. Content creators who rely heavily on front-camera quality may find Vivo more versatile overall.
Verdict
Sony delivers a professional photography experience with cleaner image processing, but Vivo provides a more advanced and versatile flagship camera package in nearly every hardware category.
Pricing
The Vivo X300 Ultra is priced around $1500 or βΉ160000, while the Sony Xperia 1 VIII is expected to cost around $1600 or βΉ140000, depending on the region and configuration. Interestingly, Sony carries the higher global pricing despite offering a comparatively weaker display and charging specifications on paper. Vivo aggressively packs flagship-grade hardware into nearly every category, making the pricing feel surprisingly competitive for what is included.
Sony justifies its premium through niche creator-focused features like microSD support, headphone jack integration, Alpha ecosystem compatibility, and cleaner Android software support. That approach will appeal strongly to photographers and long-time Xperia enthusiasts. However, mainstream flagship buyers often prioritize battery life, charging speed, and camera hardware, areas where Vivo clearly provides more value.
Verdict
The Xperia 1 VIII feels premium but specialized. The Vivo X300 Ultra offers stronger overall hardware value and feels like the better flagship deal for most buyers at this price level.
Disclaimer: Prices are approximate and may vary based on country, region, launch timing, and applicable taxes. Always check whether the listed price is for a China unit or a global/international variant when purchasing.
Conclusion
The Vivo X300 Ultra stands out with its enormous battery, extremely advanced camera hardware, optional zoom lenses, satellite communication support, and ultra-fast charging system. It feels designed for users who want the most cutting-edge smartphone technology available without compromise. The Xperia 1 VIII, on the other hand, continues Sonyβs niche flagship philosophy by prioritizing creator tools, expandable storage, professional camera controls, and audio-focused features like the 3.5mm headphone jack and Snapdragon Sound support.
Both phones target premium users, but they cater to different personalities. Vivo feels bold, experimental, and specification-heavy, while Sony feels mature, focused, and intentionally practical. The difference is not just about hardware numbers but also about the kind of user experience each brand wants to deliver.
Verdict
The Sony Xperia 1 VIII remains one of the most creator-friendly Android flagships available, but the Vivo X300 Ultra delivers the more complete ultra-premium experience overall with stronger display, battery, charging, and camera hardware.
