First impressions: design and build

Vivo keeps the T4 Ultra looking like a premium device — slim curved glass front, matte glass back in Meteor Grey or textured Phoenix Gold, and a large circular camera island that leaves no doubt this phone is camera-first. At ~192 g it feels lighter than many big-battery devices, and the 7.4 mm thickness keeps the phone pocketable while still housing a 5,500 mAh battery. The IP64 splash/dust resistance rating is a welcome practical touch for everyday use. 

What you immediately notice in hand is the quad-curved screen edge (comfortable grip) and a slightly raised camera island. Vivo bundles a charger and a case in-box — helpful for buyers who want out-of-the-box protection. The unit’s finish hides fingerprints fairly well on the Meteor Grey option. 

Display: bright, curved, and made for outdoors

Numbers that matter

On paper the T4 Ultra’s 6.67-inch AMOLED panel is impressive: 2800 × 1260 (1.5K) resolution, 120 Hz refresh rate, P3 color gamut, and a pixel density around 460 ppi. Vivo lists 1,600 nits in HBM (High Brightness Mode) on its product page; several outlets and marketing materials also call out a local peak brightness metric marketed as up to 5,000 nits — meaning the panel can hit very high local peaks for HDR highlights while still showing a lower sustained figure for general use. If you’re outdoors a lot, this phone should be readable even in strong sunlight. 

Real-world use

In daily use the 120 Hz refresh rate makes navigation and animations feel smooth and responsive. Colors are vivid but not oversaturated in natural mode, and contrast — as on most AMOLEDs — is punchy for video and gaming. The curved edges add immersion to video playback but do increase accidental touches slightly; vivo’s touch-response tuning helps mitigate that. If you favor a flat screen, be aware this is a design trade-off. 

Performance: Dimensity 9300+ and what it delivers

Vivo equipped the T4 Ultra with MediaTek’s Dimensity 9300+ (4 nm) and pairs it with LPDDR5 RAM and UFS 3.1 storage. On paper this places the T4 Ultra ahead of many midrange phones and close to true flagship performance in CPU/GPU tasks. Vivo’s marketing numbers and early benchmarks show strong AnTuTu and real-world results for multitasking and sustained performance. 

Gaming and thermal behaviour

Thanks to the 4-nm process and an Immortalis-class GPU, the T4 Ultra handles popular titles smoothly at high settings. Vivo includes “Ultra Game Mode” features and 4D game vibration to enhance immersion. Thermals are reasonable in mid-length sessions; like any powerful thin phone, sustained extreme loads will raise skin temperature but most players should see stable frame-rates for typical sessions. Real user reports and early reviews describe “decent gaming” without significant throttling for average play sessions. 

Camera system: the headline feature

This is where Vivo placed most of its bets. The T4 Ultra sports a dual 50MP sensor setup (Sony IMX921 main + Sony IMX882 periscope) plus an 8MP ultra-wide and a 32MP front camera. Vivo highlights the periscope’s ability to handle “3× optical” and a suite of software enhancements that enable 10× telephoto macro and up to 100× HyperZoom modes. The company also emphasizes stage portrait features and OIS on the main camera for steadier shots. 

Main camera (daylight & low light)

The 50MP Sony IMX921 delivers plenty of detail in daylight with natural color tones and good dynamic range. Vivo’s image pipeline leans into lively colors but not aggressively so — useful if you prefer share-ready shots without heavy editing. In low light the OIS and larger sensor area help retain detail; night mode improves shadow detail and reduces noise without turning images into oversmoothed blobs. Reviews suggest this phone can punch above its weight compared to older midrangers. 

Periscope & “10× telephoto macro”

The 50MP IMX882 periscope is the star for zoom and macro. Vivo advertises 3× optical for everyday zoom; software-assisted 10× telephoto macro (for close-up detail) and up to 100× digital HyperZoom are also available. In practice, optical (3×) and short-range telephoto shots look excellent — useful for portraits and distant subjects — and the 10× macro mode is a fun addition that produces usable closeups without the typical blur caused by being too close with a regular lens. Digital zoom beyond ~10–15× will predictably lose detail, but the software can still deliver surprising social-media-ready images. If telephoto shots are high on your list, T4 Ultra is one of the better sub-₹40k options. 

Video & selfies

Both rear and front cameras support 4K video recording. The periscope isn’t intended for continuous cinematic zoom at the highest quality, but for casual vlogging and social clips the stabilization and HDR performance are solid. Selfies from the 32MP front cam are sharp and bright, with autofocus helping framing for group shots. 

Battery life & charging: the practical side

The 5,500 mAh silicon-carbon battery is sizable — vivo manages to keep the phone slim while still offering all-day endurance under mixed use (calls, social, streaming, gaming). For moderate to heavy users, daily top-ups are expected but most reviewers report getting through a full day comfortably. 

The 90W FlashCharge wired solution is fast — vivo claims very rapid top-ups and Flipkart/official listings back the 90W spec. If you need a quick boost before heading out, the T4 Ultra charges significantly faster than many competitors that top out at ~65W or lower. As always, battery longevity depends on charging habits; fast charging is excellent for convenience. 

Software & updates: Funtouch OS 15 (Android 15)

The T4 Ultra ships with Funtouch OS 15 on Android 15. Vivo’s Funtouch 15 brings AI utilities (Circle to Search, AI transcription, enhanced note-taking, AI Eraser and image tools) that are integrated into the camera and system apps. Vivo’s PR and press materials indicated multi-year update commitments (marketing mentions up to 3 major Android updates and multiple years of security updates in various release notes), but buyers who care deeply about update guarantees should verify the exact promise for their region and variant at purchase. 

How the Vivo T4 Ultra compares (short)

If you’re sizing up competitors in the mid-premium space, here’s a rough guide:

• Vs OnePlus 13R / iQOO Neo10 series — T4 Ultra competes strongly on camera hardware and battery; some rivals might edge it in raw GPU performance or UI preference. 

• Vs Flagships (Galaxy S25 range / iPhone 16 Pro) — These flagships still win on absolute imaging versatility, software ecosystem, and some specialist features — but the T4 Ultra delivers flagship-style telephoto and strong everyday performance at a fraction of the cost. 

• Vs budget-heavy phones — T4 Ultra is pricier but gives flagship camera perks, higher brightness, and faster charging worth the jump if you want better photos and display. 

Who should buy the Vivo T4 Ultra?

Buy it if:

• You want a mid-premium phone with an excellent telephoto/periscope camera.

• You value a bright, curved OLED and smooth 120 Hz experience for media and gaming.

• Fast charging and a big battery are priorities for daily life. 

Skip it if:

• You need the absolute cleanest Android experience (stock Android fans may prefer Pixel).

• You prioritize long-term software guarantees above all (check the local update promise before buying). 

Final verdict — is it worth it?

Vivo’s T4 Ultra is a thoughtful mid-premium offering: it packages flagship-adjacent camera hardware, an eye-catching curved display with very high local peak brightness claims, speedy MediaTek silicon, and a large battery with 90W charge — all at a competitive price point. For photography-minded users who don’t want to spend flagship money, the T4 Ultra is a compelling pick in 2025. A few caveats — software update clarity and true long-term support should be verified in your market — but overall, this phone gives better camera and display value than many rivals in the sub-₹40k bracket.

Buyer checklist (quick)

• Confirm the exact RAM/storage variant and price from Flipkart or vivo e-store. 

• If display peak brightness matters, remember marketing uses different metrics (HBM vs local peak). 

• Test the periscope zoom in store/sample images if possible — 3× optical is great; 100× is digital and best for social crops. 

• Keep an eye on official update policy for your country/variant before final purchase.

Conclusion

The Vivo T4 Ultra is one of those rare mid-premiums that feels unapologetically focused — it bets on a high-quality display and a flexible periscope camera to steal the spotlight. For buyers who want flagship camera tricks without flagship prices, this phone deserves strong consideration in 2025. If your priority list centers on telephoto photos, a bright curved screen and fast charging, add it to your shortlist — then compare real photos and local prices before you decide.
