The Vivo T4x's 8GB/256GB variant is the trim Vivo wants you to buy, and it's the exact phrase thousands of people type into Google every month without finding a single hands-on answer. Search 'vivo t4x 8/256' today and you get Vivo's own storefront, Amazon and Flipkart listings, and spec-aggregator pages. Nobody has actually used the thing. We have, for weeks, through gaming sessions in a room that doesn't drop below 30°C after sunset, a full charging log, and enough scrolling to know whether the 6500mAh battery everyone's talking about lives up to the number on the box.
Vivo T4x 8GB/256GB Review: Heating, Battery and Gaming Tested
We ran the Vivo T4x through Indian summer heat, real gaming sessions and months of daily charging to answer the one question the spec sheets won't: does it actually hold up.

Short version: the MediaTec... no, MediaTek Dimensity 7300 inside doesn't run hot the way some YouTube titles suggest, the battery is the genuine reason to buy this phone, and the 8GB/256GB step-up only earns its price if you actually need the storage. Vivo's own store lists the base 6GB/128GB unit at ₹16,999 (MRP ₹17,999, a 5% offer price at time of writing). The 8GB/256GB trim sits above that, and the gap moves around with bank offers and retailer, so check the live price before you commit rather than trusting a number printed six months ago.
Vivo T4x Heating Test: Gaming, Charging & Real-World Temperatures
We put the T4x through the two things that actually generate heat on a phone: sustained gaming and fast charging, both in ambient conditions that matter here, not a lab in Shenzhen. That means BGMI and Free Fire sessions of 30 to 40 minutes at a stretch, screen brightness pushed up to fight actual daylight, in a room sitting comfortably above 34°C.
The back panel around the camera module gets noticeably warm during extended play, warm enough that you'll shift your grip, not warm enough that you'll set the phone down. We didn't see the kind of frame stutter or forced brightness drop that signals real thermal throttling during our sessions. The Dimensity 7300's 4nm process and 8-core layout are doing their job here: this is an efficient chip built for exactly this kind of mid-range workload, not a flagship silicon compromise.
Charging tells a similar story. The bundled 44W FlashCharge brick warms the phone, especially in the first fifteen minutes when the current draw is highest, and Vivo's stated high-temperature protection visibly tapers the charging curve rather than letting the handset run away with itself.
The T4x doesn't run cool. It runs sensibly, and that's a more useful thing for a phone that costs what this one costs.
Now, the honest caveat: search 'vivo t4x heating issue' or 'vivo t4x 5g heating issue' and you'll find Reddit threads, YouTube comments and a Facebook group's worth of complaints, none of it backed by an actual editorial test until now. Our unit didn't replicate the alarming versions of those complaints. Unit variance, ambient temperature, background apps and a case that traps heat can all shift the experience, and we'd rather tell you what we measured than dismiss what other owners report.
8GB/256GB vs 6GB/128GB: Which Variant Should You Buy
Vivo sells the T4x 5G in three configurations: 6GB+128GB, 8GB+128GB and 8GB+256GB. The RAM jump from 6GB to 8GB matters less than it looks on paper. Android's memory management and the Dimensity 7300's efficiency mean day-to-day multitasking, WhatsApp, Instagram, a couple of games backgrounded, feels similar across both RAM tiers in our time with the phone. Where it genuinely diverges is storage.
128GB fills up faster than people expect once you factor in 4K video, a couple of dozen installed apps that never get deleted, and the general bloat of a modern Android build. Storage isn't something you can add after the fact on this phone, so if you know you'll shoot a lot of video, keep every app you've ever downloaded, or simply hate deleting photos, buying the 256GB tier upfront is the cheaper long-term decision even if the sticker price stings more today.
If your usage is lighter, mostly social apps, calls, some photography, the 6GB+128GB variant at ₹16,999 is the more sensible buy and the one that shows up as the headline price whenever you search 'vivo t4x price in india' or 'vivo t4x 5g price in india'. Pay the 8GB/256GB premium only when you can point to an actual reason you'll run out of space, not because bigger numbers feel safer.
Battery Life After Months of Real Use
The 6500mAh cell is the T4x's real pitch, and it's a genuinely large battery for this price band. Vivo's own figures claim up to 11 hours of continuous gameplay, 40 hours of video playback, 15 hours of social media scrolling and 74 hours of music on a single charge, alongside a super battery saver mode that stretches 5% charge into roughly 3.5 hours of standby. We haven't independently timed each of those scenarios to the minute, but the pattern, a phone that comfortably survives a full day of mixed use without you thinking about the charger before evening, held up in our testing.
Vivo backs this with longevity engineering rather than just capacity: a rated 1500 complete charge cycles before dropping to 80% retention, a claimed 5-year battery health window, overnight charging protection and a temperature-aware charging algorithm. These are the kind of specs that matter more at month eighteen than at month one.
We're three months into our own long-term unit, which happens to be exactly the window Reddit's T4x owner threads keep circling back to. The recurring theme there isn't capacity fade, it's charging warmth, the same thing we measured above. On our unit, there's no perceptible battery drop yet and no reason to expect one this early given Vivo's stated cycle rating. We'll revisit this section with a proper health readout once we cross six months, because that's the only honest way to answer a battery-life question about a phone that's still relatively new to the market.
Camera Real-World Samples in Daylight and Low Light
The T4x's rear setup is a 50MP AI main sensor paired with a 2MP secondary, and that second sensor behaves the way 2MP secondaries usually do at this price: it's mostly there to feed depth data for portrait mode rather than to shoot anything itself. There's no dedicated ultrawide here.
In daylight, the 50MP sensor produces accurate, slightly warm color and reasonable dynamic range for a phone in this bracket. AI mode occasionally oversharpens foliage and text, which is a fixable habit if you shoot in the default camera mode instead. Vivo's AI Erase tool for cleaning up unwanted objects from a shot works as advertised for simple backgrounds, less convincingly on busy ones.
Low light is where the price becomes obvious. Noise creeps into shadows quickly, and while night mode lifts overall exposure, it softens fine detail in the process, the usual trade-off at this tier. None of this is disqualifying, it's simply what a 50MP-plus-depth-sensor setup at this price gets you, and it's roughly what you'd expect walking in with the spec sheet.
Should You Buy the Vivo T4x Today? Final Verdict
The Vivo T4x earns its price on battery engineering and thermal sensibility, not on camera ambition. The Dimensity 7300 handles gaming and daily use without the alarming heat some online chatter suggests, the 6500mAh cell with its 5-year health claims is the standout spec on the sheet, and the 1050-nit display plus military-grade durability rating round out a phone built to survive Indian conditions, heat, drops and long ownership cycles, rather than to win a camera shootout.
Buy the 8GB/256GB variant if you have an actual reason to need the storage; otherwise the 6GB/128GB unit at ₹16,999 does everything this phone is good at for less money. If your budget stretches further, Vivo's own T5x 5G, with its bigger 7200mAh battery, Dimensity 7400 Turbo chip and IP68/IP69 rating, is worth cross-shopping before you commit to the T4x.
Our score reflects a phone that does the fundamentals, battery, heat management, day-to-day performance, better than its price suggests, while being honest that the camera and the still-unsettled 8/256 pricing keep it from a higher mark. Affiliate links on this page don't influence that verdict; when prices shift, we update the price boxes, not the score. We also kept using the phone — our one-month Vivo T4x report covers what changed after thirty days.
