Review Summary
Expert Rating
Tecno’s Spark series has mostly lived in the budget space, with phones like the Spark 30C (review) 5G priced between 10,000 and 13,000 rupees in India. With the Tecno Spark 50 5G, Tecno is nudging the lineup upwards, pricing it at 16,999 rupees for the base 4GB + 128GB model and 18,999 rupees for the 6GB + 128GB variant.
This time, you get a much bigger 6,500 mAh battery instead of the older 5,000mAh unit, faster 45W charging, a newer Dimensity 6400 chipset, and things like IP64 protection, MIL STD 810H durability and 4×4 MIMO support for better network performance. On paper, the Spark 50 5G is no longer just a basic first 5G phone; it is trying to be a more rounded all-rounder in the lower mid-range. This also means it now faces stronger rivals, so let’s see how much value it delivers at its new price.

Design: Looks good, feels sturdy
The Tecno Spark 50 clearly draws inspiration from Google’s Pixel lineup for its design, particularly in how the rear camera module is laid out. The matte finish on the back looks clean and does a decent job of keeping smudges and fingerprints at bay during everyday use. The phone comes in Ink Black and Champagne Gold, with both options carrying a simple, refined look that works well at this price.
At 8.18mm thin and 210g, the Spark 50 5G does feel a little dense in the hand initially, though you do tend to get used to it fairly quickly. The buttons are well placed, with the power and volume keys at an accessible height on the right spine, easy to reach with the thumb despite the phone’s size. The phone also includes a 3.5mm headphone jack, something I missed dearly and am happy to see make a comeback.
| Smartphone | Thickness | Weight | IP Rating |
| Tecno Spark 50 5G | 8.18 mm | 210 grams | IP64 Pro |
| OPPO K14 5G | 8.6 mm | 216 grams | IP69 |
| iQOO Z11x | 8.39 mm | 219 grams | IP68 +IP69+ |
On the durability front, the Spark 50 5G carries an IP64 rating and MIL-STD-810H military-grade certification, meaning it can withstand dust, light splashes, and drops from up to 1.5 metres. Although IP64 is a step behind what some rivals at this price offer, like the Oppo K14 (review), which offers multiple IP ratings.
Display: Big screen with some caveats
The Tecno Spark 50 5G sports a 6.78-inch IPS LCD panel with a 120Hz refresh rate and a clean punch-hole cutout, and it makes a decent first impression with its size. Brightness indoors is acceptable at 560 nits, and the large screen makes scrolling and watching content comfortable enough for everyday use.
The HD+ resolution at 760 x 1576p delivers satisfactory output, but I feel the resolution could have been better. It isn’t as sharp as an FHD panel, and at a time when most phones in this price segment were shipping with FHD+ displays last year, it is hard not to feel the difference. In terms of colours, the display has a pretty neutral tone, and you can nudge it towards a warmer or cooler output using the display settings to best suit your needs.
| Smartphone | Display | Peak Brightness |
| Tecno Spark 50 5G | 6.78 inches - IPS LCD | NA |
| OPPO K14 5G | 6.75 inches - LCD | NA |
| iQOO Z11x | 6.76 inches - LCD | NA |
The panel also offers a 120Hz refresh rate, which sounds good on paper but is a bit misleading in practice. Only a handful of apps actually run at the full 120Hz, with most of the system defaulting to 90Hz. Outdoors, the 560 nits peak brightness can also feel limiting under direct sunlight.
In terms of audio, you only get a single down-firing speaker unit, which provides functional value but, compared to a stereo setup, lacks the depth you’d expect. The good thing is that there’s a 3.5mm audio jack, which lets you plug in headphones or earphones to address this limitation. Something I would love to see make a comeback in phones.
Battery life: could have been better
The Tecno Spark 50 5G packs a 6,500mAh battery, and on paper, that capacity sounds like it should last well beyond a day. In practice, however, the endurance does not quite live up to what the numbers suggest.
The drain during regular use runs higher than expected compared to rivals, and gaming on this phone only worsens it. Running games at 90fps in particular caused significantly higher battery drain, roughly 20 percent more compared to rivals in similar tests.
For most users, the Spark 50 5G will still comfortably see through a full day of regular use. The PCMark battery benchmark results confirm the same, with a decent output. Heavier users, however, or those who game frequently, will likely need to plug in by night rather than stretching it to the next morning. Given the large battery, the actual endurance of it in day-to-day use feels a bit more underwhelming than what one would expect.
| Smartphone | Battery Capacity | Charging Support | Charging time (20% to 100% ) |
| Tecno Spark 50 5G | 6500 mAh | 45W Fast Charging | 1h 5m |
| OPPO K14 5G | 7000 mAh | 45W Super Charging | 1h 27m |
| iQOO Z11x | 7200 mAh | NA | 1h 16m |
It’s not all bad, however, as the 45W fast charging does help make up for it, taking the phone from 20 to 100 percent in around 65 minutes, which is a fantastic result for a battery this size.
Performance: Decent for daily use, modest under pressure
The Tecno Spark 50 5G runs on the MediaTek Dimensity 6400 paired with up to 6GB of RAM and 128GB of storage. For general day-to-day use, it holds up well enough. App launches, social media, and casual browsing all feel reasonably smooth, and most users picking this up as an everyday device will find it gets the job done without much complaint.
Push it harder, though, and the limits show up fairly quickly. Heavy multitasking and demanding tasks can cause lag to creep in, and the 6GB RAM ceiling leaves little headroom when several apps are running simultaneously. Compared with rivals in the segment, the Spark 50 5G is a fairly modest performer.
Gaming performance, however, is a more pleasant surprise. Tecno appears to have done some optimisation work for popular FPS titles, and it shows. BGMI in particular runs well, clocking an average of 54 FPS over 30 minutes at medium settings. COD: Mobile is where it struggles more, averaging 40 FPS, which is lower than what rivals manage. If BGMI is your primary game, the Spark 50 5G will serve you well. For other demanding titles, you may need to dial down the settings.
The Spark 50 runs on HiOS, Tecno’s custom Android skin based on Android 16. The software is clean, responsive, and fluid in day-to-day use. he speciality of the software this time around is that it’s packed with a slew of convenient features, such as Active Noise Cancellation, AI WhatsApp Assistant, Ella Alarm Announcement, AI Writing Assistant, AI Eraser 2.0, AI Image Extender and Ella-powered tools.
While there are a bunch of 3rd party apps out of the box, most of them can be uninstalled. It is a functional, no-fuss software that does what it needs to. There’s no official word on the software support cycle for this device, and based on past Spark series launches, it may not receive any new OS upgrades.
Good daylight cameras
The Tecno Spark 50 5G has a 50MP primary camera on the back paired with a 2MP auxiliary lens and an 8MP selfie camera. Outdoor shots in daylight look natural and well-balanced, with colours that do not feel overdone and a good ability to hold detail in both bright and darker parts of the same frame.
The front camera delivers satisfactory results as well. The selfies look natural without heavy processing, and the phone handles tricky lighting situations, like shooting against a bright sky, better than most phones at this price point.
Once the light drops, though, things get a bit tricky for the device. Night mode helps to a degree, but the camera tends to struggle with light sources in the frame, resulting in softer images with some unwanted glare. It is still usable, but low light is clearly not where this camera is most comfortable.
The sweet spot for the Spark 50 5G’s cameras is well-lit outdoor conditions. That is where it consistently delivers results that look good without any extra effort from the user.
I compared the phone’s cameras against the Oppo K14 (review) to see how it holds up against the competition.
Daylight
In daylight, the Tecno Spark 50 5G produces photos that look close to what your eyes see. Colours look natural, and it handles bright skies and shadowy areas in the same shot reasonably well. The OPPO K14 captures finer details more sharply, so things like leaves and building textures look crisper when you zoom in.
Portrait
In portrait mode, the Tecno Spark 50 5G produces more natural-looking skin tones and retains facial details well. The background blur is applied cleanly, with the edges around the subject separated accurately. The OPPO K14 leans towards a more processed look, with slightly off skin tones and less precise edge separation.
Selfie
In selfies, the Tecno Spark 50 5G produces more natural-looking skin tones and holds onto facial details better. It also handles bright backgrounds more gracefully, keeping the face well-exposed without losing too much of the background. The OPPO K14 produces a slightly flatter, less accurate look by comparison.
Low light
With night mode on, the OPPO K14 takes the lead. It controls stray light and lens flares more effectively, preventing bright light sources from bleeding into the rest of the shot. Details are sharper and colours look more accurate too. The Tecno Spark 50 5G struggles more with light sources in the frame, and the overall output looks softer in comparison.
Final Verdict
Starting at Rs 16,999 for the 4GB variant and Rs 18,999 for the 6GB model, the Tecno Spark 50 5G gets a lot of the everyday basics right. The design is clean and well-built, the camera performs well in good light, and the 45W charging keeps the large battery topped up without much waiting. For a general user who wants a reliable, no-fuss daily driver, there is a lot to like here.
It falls short in the areas that matter when you push it. The processor handles routine use comfortably but starts to show its limits with heavy multitasking or demanding apps. Low-light camera performance also leaves room for improvement. Taken together, these gaps are enough to give some buyers pause, especially at a price that now puts it in direct competition with stronger options.
The OPPO K14 (review), for instance, delivers better low-light photography; likewise, the iQOO Z11x (review) offers a more powerful processor, an FHD+ display, and smoother overall performance if gaming or multitasking is a priority. All that being said, if you want a phone with a good build, good daylight cameras, capable selfies, and fast charging, the Spark 50 5G makes a reasonable case for itself at this price.
