Infinix Smart 10 Plus vs. Tecno Spark 40: Which Budget-Friendly Phone Should You Buy?
It really comes down to what matters more to you: longer battery life, or less downtime.
When it comes to choosing between two Transsion smartphones, it can be fraught with indecision. Why? Because sometimes you feel like you're looking at twins with slightly different names. Same vibe, same budget range, same UI quirks, and almost identical performance on paper.
The newly launched Infinix Smart 10 Plus and Tecno Spark 40 are a perfect example of this. Both are targeted at entry-level users who want big screens, long battery life, and smooth everyday use, but each has its edges that could matter, depending on what you're looking for.
So if you're trying to make the right call between these two, let’s break it down under the key things that actually matter.

1. Design & Build
First impressions—both phones come in with that familiar budget Transsion design. Plastic builds, glassy surfaces, rounded corners, and flashy back panels. But here’s where it starts to split.
The Infinix Smart 10 Plus keeps it slim and lightweight at 7.99 mm thick and 198 g. It’s got that IP64 dust and splash resistance and comes in a nice range of colors like Ruby Red and Iris Blue. Dual stereo speakers with what Infinix calls "300% Ultra Volume" are a plus for loud environments.
Tecno Spark 40, on the other hand, adds a bit more to the mix. Still IP64 rated, but also throws in Dolby Atmos support, USB-C 2.0, and an infrared remote control (surprisingly useful). It feels more “premium” in features, even though it’s still plastic through and through.
2. Display
On paper, both phones have 6.67-inch LCDs with a 120 Hz refresh rate, which is impressive for their price point.
But there are small differences in brightness and quality. The Infinix Smart 10 Plus pushes up to 700 nits peak brightness, which means better outdoor visibility. The Tecno Spark 40 doesn’t shout about brightness, and even though it also has 720p resolution, the experience might feel slightly dimmer in direct sunlight.
3. Performance
Performance-wise, the Infinix Smart 10 Plus is powered by a Unisoc T7250 processor, paired with up to 8GB RAM and 128GB internal storage.
Tecno Spark 40 steps it up with a MediaTek Helio G81, the same base 4GB RAM but can go up to 8GB with virtual RAM, and also up to 128GB storage.
Between the two, the Helio G81 has slightly better real-world performance than the Unisoc chip. Apps open faster, multitasking feels smoother, and casual gaming is less stuttery.
4. Cameras
For users keen on cameras, the Infinix Smart 10 Plus rocks just an 8MP rear and 8MP front camera setup. That’s barely enough for good lighting selfies or quick document snaps. You’re not getting much detail or sharpness here.
However, the Tecno Spark 40 throws in a 50MP rear camera and an 8MP front camera. Daylight shots, portraits, and even low-light photos are just on another level here.
5. Battery Life & Charging
Battery capacity is big on both ends, but the approach is different.
The Infinix Smart 10 Plus comes with a 6000mAh battery and 18W charging. That’s a tank. Two full days of light to moderate use, easy. But it charges slowly.
The Tecno Spark 40 offers 5200 mAh, which is still solid but not as beastly. However, it makes up for it with 45W fast charging, meaning you’re back up in under an hour.
6. Software
The Infinix Smart 10 Plus runs Android 15 with XOS 15—a clean, stable setup that feels future-proof with the latest Android version right out of the box.
The Tecno Spark 40 also ships with Android 15, layered with HiOS 15.1. It’s equally up-to-date, but HiOS tends to be a bit heavier and more customized, which might slightly tone down the stock Android experience.
Both phones come with some bloatware, system-wide dark mode, app cloning, and gaming tools. Still, Infinix edges it out with a slightly cleaner, closer-to-stock feel—even if both are running the same Android version.
7. Price
In terms of price, the Infinix Smart 10 Plus goes for around ₦126,000, while the Tecno Spark 40 sits higher at ₦142,700. That’s a ₦16,700 gap.
It might not sound like a lot in phone terms, but for many of us, that’s a full week’s transport and airtime—or even a small data plan plus a decent meal or two. So the question is, what exactly are you getting for that extra cash?
If you break it down, that ₦16K+ gives you a much better camera setup, noticeably faster charging, and a more powerful processor. But if those aren’t top priorities for you—and you’d rather put the savings into something else—then the Infinix is more than capable of holding its own.
Conclusion
Both of these phones are strong picks in the entry-level space, but your choice depends on what you care about more.
If you're all about lasting battery, a cleaner Android, and saving cash, the Infinix Smart 10 Plus is a solid everyday companion. But if you're willing to pay a bit more for better performance, camera sharpness, and fast charging, then the Tecno Spark 40 gives you more long-term value.
Overall, there’s no wrong pick here—just what fits your hustle and how far you want your ₦100K+ to go.
