This comparison treats the TECNO as the SPARK 50 5G, not the separately listed SPARK 50. That distinction matters: TECNO’s SPARK 50 5G page lists a Dimensity 6400 5G chip, while its Bangladesh SPARK 50 page lists a G81 processor. The phones are close on headline battery capacity and display refresh rate, but the available evidence does not establish a performance, camera, or battery-life winner.

Performance and 5G: Dimensity 6400 vs Dimensity 6300
TECNO advertises the SPARK 50 5G with a MediaTek Dimensity 6400 5G, while vivo lists a MediaTek Dimensity 6300 for the Y21 5G. Both are 5G platforms in the specified models. The chipset names alone do not establish which phone runs faster: the available sources do not provide comparable independent benchmarks or hands-on testing. RAM configuration, storage, thermal behavior, software, and the specific apps being used can also affect everyday responsiveness.
Display: close in size, both up to 120Hz
The reported SPARK 50 5G display is 6.78 inches with 720 × 1576 resolution and a 120Hz refresh rate; those figures come from 91mobiles. vivo’s official Y21 5G specifications list a 6.74-inch, 1600 × 720 LCD with a refresh rate of up to 120Hz. The nominal size difference is small, and both are HD-class displays with 120Hz-class refresh rates. The cited facts do not establish comparative brightness, color accuracy, or outdoor readability.

Battery and charging: equal listed capacity, 1W apart
TECNO specifies a 6500mAh battery and 45W Super Charging. vivo lists a 6500mAh typical battery and 44W charging. On the headline ratings, capacity is equal and charging differs by 1W. Those figures do not predict a reliable real-world battery-life or charge-time winner: no controlled comparison is available, and actual results depend on usage, settings, charger, and conditions. TECNO says its battery data comes from TECNO Laboratory and that actual data may vary.
Quick wins for a faster PC:
Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Cameras: similar main-camera megapixels, no proven winner
TECNO promotes a 50MP FlashSnap rear camera. vivo lists a 50MP + 0.08MP rear camera and a 5MP front camera. The listed megapixel counts do not show how well either phone handles detail, motion, low light, skin tones, or video. The cited material does not provide controlled sample comparisons, so it cannot support a camera-quality verdict.

Durability: read the ratings as different brand claims
TECNO advertises IP64 dust/water resistance and military-grade shock-resistance certification. vivo lists IP65 and promotes SGS 5-Star Drop Resistance with military-grade certification. These are manufacturer-stated claims, not equivalent independent results. IP ratings describe protection against dust and water under specified test conditions; they do not establish drop-proofing, and the two brands’ additional certification claims should not be treated as interchangeable. Follow each phone’s care guidance and do not assume either is waterproof.
Software and support: listed versions differ, update duration is unknown
vivo’s cited specification page lists Android 16 with OriginOS 6. TECNO’s cited product-page material promotes TECNO AI and FreeLink 2.0 but does not establish an exact operating-system version in the captured specifications. TECNO also uses the phrase “5 Years Lasting Fluency Guarantee,” while vivo promotes a “50-months smooth experience guarantee.” The cited passages do not define these promotions as comparable Android or security-update commitments. They are not enough to determine how long either phone will receive software updates.

Price difference in India: compare live, like-for-like offers
A stable current price gap cannot be established from the cited evidence. vivo’s India shop displays an MRP of ₹32,999 for the Y21 5G 4GB+128GB in Champagne Gold; that is an MRP, not necessarily the current sale price, and shop price or stock may change. The shop also lists 6GB and 8GB 128GB options. No official India price for the TECNO SPARK 50 5G is established by its cited product page. 91mobiles shows Amazon offer snapshots, but result variants report differing prices and listings can change.
For a useful comparison, check both phones at the same time and match RAM, storage, color where relevant, seller, warranty, and any bank or exchange offer. An apparent difference between unlike configurations or a changing listing is not a dependable model-to-model price comparison.

Which one should you choose?
- Consider the SPARK 50 5G if its live price for the configuration you want is preferable and you value its stated 45W charging or want the Dimensity 6400 5G model. The cited facts do not prove a speed advantage over the vivo.
- Consider the Y21 5G if you prefer vivo’s listed Android 16 and OriginOS 6 details or its officially listed display and camera specifications. Its ₹32,999 MRP applies specifically to the 4GB+128GB Champagne Gold variant shown on vivo’s shop page, not necessarily to every configuration or current offer.
- Compare the actual listing before deciding: confirm the exact SPARK 50 5G name, RAM and storage, seller, warranty, and live price. Decide based on the features and terms you can verify rather than assuming a benchmark, camera, or endurance winner from headline specifications.
